What You're Really Drinking: The Degradation of British Beer

An investigation into what mass-market brewers put in your pint; and what they are NOT required to tell you

National Health Restoration Series — Article 5

Beer is supposed to be one of the simplest products in the world. Water, grain, hops, yeast. Four ingredients. The Germans codified this in 1516 with the Reinheitsgebot, the Beer Purity Law, mandating that beer could only contain barley, hops and water, with yeast added later once its role in fermentation was understood [1]. Five centuries on, many German breweries still voluntarily brew to those standards, and the ethos of that law, transparency, purity and respect for the consumer, remains central to how much of Europe views beer.

In Britain, however, you are likely drinking something rather different. The pint in your hand may contain glucose syrup, maize starch, rice, propylene glycol alginate, caramel colouring, isinglass derived from fish swim bladders, and an array of processing aids that never appear on any label, because, in the United Kingdom, beer is not required to carry an ingredients list. The exemption is categorical. Any alcoholic beverage above 1.2% ABV is exempt from the obligation to list its ingredients and exempt from the requirement to provide a nutrition declaration [2][3]. The only mandatory disclosure is the presence of specific allergens, the ABV, and the volume. Everything else, every adjunct, every syrup, every additive, every processing chemical, can remain entirely undisclosed.

This is the regulatory environment in which the largest beer companies in the world operate when they sell to British consumers. And they have used it, methodically and profitably, to transform what Britain drinks into something that would be unrecognisable to the brewers who built this country’s brewing tradition.

Part One: The Ingredient You Cannot See

The most widespread adulterant in mass-market British beer is glucose syrup. Derived primarily from maize or wheat starch, glucose syrup is cheaper than malted barley and serves as a source of fermentable sugar that produces alcohol without contributing the body, flavour or complexity that comes from grain [4]. British brewing has a long history of sugar adjuncts: the 1847 “Free Mash Tun” legislation gave UK brewers unique latitude to use sugars in brewing, a freedom their continental counterparts did not enjoy [4]. What began as a historical quirk has become an industrial strategy. Where most European and American brewers use solid grain adjuncts such as rice or wheat, UK and Australian brewers have overwhelmingly favoured syrups, because they can be added directly to the wort kettle without using mash tun capacity, increasing brewery throughput without additional capital investment [4].

For the consumer, the effect is a thinner, lighter beer with less body and less flavour, and a product that costs significantly less to produce. For the brewery, glucose syrup is a direct route to higher margins. But you will never know it is there, because no ingredients list is required.

Beyond glucose syrup, the list of permitted additives and processing aids in British beer includes substances that would surprise most drinkers. Propylene glycol alginate, or PGA, is a chemically modified seaweed extract used as a foam stabiliser; it creates the appearance of a thick, lasting head on beer that would otherwise have poor foam retention [5][6]. The foam produced by PGA has, according to the Oxford Companion to Beer, “substantially different aesthetic qualities than natural foam” [5]. It is, in effect, an artificial simulation of what a properly brewed beer would produce naturally. Isinglass, a collagen derived from dried fish swim bladders, is used by many British brewers as a fining agent to clarify beer, a practice dating to the eighteenth century [7]. While isinglass is filtered out before the finished product reaches the consumer, its use renders the beer unsuitable for vegans and vegetarians, a fact that is not required to be disclosed unless allergen labelling applies [7]. Caramel colouring, manufactured by heating ammonia and sulphites under high pressure, is used by some breweries to darken beers artificially rather than using roasted malts [8]. Newcastle Brown Ale used caramel colouring from 1927, a fact the brewery acknowledged only after public pressure [8][9]. The compound used, Class IV caramel colour, contains 4-methylimidazole, which has been classified as a possible carcinogen by the International Agency for Research on Cancer and would require a cancer warning label in the state of California [8].

None of these additives appear on the product. The consumer has no way to distinguish between a beer whose colour comes from roasted malt and one whose colour comes from an industrial caramel compound. There is no way to know whether the head on your pint is a product of natural protein and hop interaction or a chemical foam stabiliser. There is no way to know whether your beer was clarified using fish bladders.

The information simply does not exist on the label, and there is no legal requirement that it should.

Part Two: The Systematic Weakening of British Beer

If what goes into British beer is opaque, what has been taken out of it is conspicuous, if you have been paying attention. Over the past fifteen years, the major brewers have systematically reduced the alcohol content of their flagship brands sold in the UK, a process that saves them millions in excise duty while delivering a materially weaker product to the consumer at the same or higher price.

The case study is Stella Artois. In Belgium, where it originated, Stella Artois is brewed at 5.2% ABV, the standard for Belgian pilsners [10]. When it first arrived in the UK, brewed under licence by Whitbread from 1976, it was marketed at 5.2% with the slogan “Stella’s for the fellas who take their lager strong” [10]. The brand’s UK identity was built on that strength. Then the reductions began. In 2008, Stella was cut to 5.0% [11]. In 2012, it was cut again to 4.8%, a move AB InBev described as being “in line with evolving UK category trends” [12]. In 2020, it was cut once more to 4.6% [11]. The beer that British consumers now purchase as Stella Artois is 11.5 per cent weaker than the beer sold in Belgium under the same name. AB InBev has saved an estimated £8.6 million per year in duty on off-trade sales of Stella alone from just one of these reductions [12][13].

Stella was not alone. In the same period, Budweiser and Beck’s were both reduced from 5.0% to 4.8% in the UK [12]. Carlsberg Export and Cobra followed suit [14]. And in 2025, the process accelerated. Following the introduction of the UK’s new alcohol duty structure in August 2023, which created a significantly lower tax band for beers at or below 3.4% ABV, breweries moved aggressively to exploit the threshold. Carlsberg Marston’s reduced its flagship Carlsberg Pilsner from 3.8% to 3.4% [15]. Heineken reduced Sol from 4.2% to 3.4% [15]. Grolsch Premium Pilsner was cut from 4.0% to 3.4% in the UK, saving approximately 23 pence in excise duty per 440ml can [15]. Foster’s and Stella Artois were moved to the same bracket [15].

An analysis by the brewing blog Beer Nouveau calculated the financial implications. Based on Carlsberg’s 2022 UK sales of 651,246 hectolitres, the reduction from 3.8% to 3.4% ABV combined with the new Draught Relief rate would save Carlsberg approximately £33.4 million per year in duty [16]. For Carling, the potential saving was calculated at £108.6 million [16].

Every one of these reductions has been presented to consumers as a response to “evolving trends” or a commitment to “responsible drinking” or “moderation.” Not one has been accompanied by a reduction in price. The product is weaker. The price is the same or higher. The brewery pockets the duty saving. The consumer receives less of the thing they are paying for, alcohol, and is told it is for their own good.

Part Three: The Carling Scandal - Brewing Below the Label

The most brazen example of this practice was exposed not by a journalist or a regulator, but by Her Majesty’s Revenue and Customs. In a case heard at the Royal Courts of Justice, Molson Coors admitted that its Carling brand, one of the most popular lagers in the United Kingdom, had been brewed at 3.7% ABV since September 2012, despite being labelled and sold at 4.0% [17]. The discrepancy was not accidental. Tribunal papers revealed that Carling had tested a range of strengths below 4.0% to gauge consumer reactions, and had deliberately chosen not to update the label. The reason, according to evidence given by Molson Coors’ vice president Philip Rutherford, was to prevent retailers from demanding a share of the duty savings [17].

For at least five years, millions of British consumers bought Carling believing they were drinking a 4.0% beer. They were drinking a 3.7% beer. The company knew. The company chose not to disclose it. EU labelling regulations permitted a tolerance of plus or minus 0.5% on declared ABV for products between 1.2% and 5.5%, meaning that the 0.3% discrepancy was technically within legal limits [17]. HMRC accused Molson Coors of underpaying more than £50 million in excise duty, but the brewery won the case, arguing that the lower strength was intentional and the duty had been paid on the actual alcohol content [17].

The Carling case illustrated in miniature everything wrong with the British beer market: a product brewed weaker than declared, a consumer told nothing, a regulator unable to act, and a company whose only miscalculation was failing to match its tax payments to its deception. The label said 4.0%. The beer said 3.7%. The law said that was fine.

Part Four: High Gravity Brewing - Your Beer Was Watered Down

The mechanism by which major breweries achieve these precise ABV adjustments is a technique called high gravity brewing. The principle is straightforward: brew a concentrated beer at a higher ABV than the intended finished product, then dilute it with specially treated water before packaging to reach the target strength [18][19]. The process has been used by virtually every major commercial brewery in the world for decades and is the primary method by which large-scale brewers maximise throughput without expanding their physical brewing capacity [18].

In practical terms, a brewery might brew a wort at 7, 8 or 9 per cent ABV, ferment it, and then dilute it with de-aerated water, water that has been heated and carbonated to remove dissolved oxygen, to produce a finished product at 4 or 5 per cent [20]. Colour corrections are added in-line using products such as caramel colour or Weyermann Sinamar, and hop bitterness is adjusted using iso-hop extract [20]. The entire process can be monitored and validated in-line, measuring alcohol, colour and IBUs on the way to the bright beer tank [20].

The result is a beer that has been literally watered down, diluted by as much as 50 per cent, with adjustments made chemically to approximate the appearance and bitterness of a normally brewed product. Studies have shown that high gravity brewing produces beer with significantly inferior foam retention, reduced levels of hydrophobic polypeptides (the proteins that create stable natural foam) and altered flavour profiles characterised by increased ester production [18][19]. A traditionally minded German brewer from Göller brewery observed that a diluted high gravity beer “will unfortunately keep its low foam status” regardless of the water addition, and that the resulting product requires special malts and other additives to compensate for poor mouthfeel and colour distortion [21].

This is the beer the British public is drinking. Not a beer brewed to 4.6% or 3.4%. A beer brewed to 8 or 9 per cent and then diluted with water to reach the number on the label. The water used for dilution is, of course, subject to the same concerns documented in Article 4 of this series: municipal mains water carrying PFAS, pharmaceutical residues, microplastics and disinfection byproducts, treated but not tested for many of the contaminants now known to be present in the UK water supply.

Part Five: The Water in Your Beer

Water constitutes approximately 90 to 95 per cent of finished beer by volume. It is the single largest ingredient. And in Britain, the water used by major breweries is drawn from the mains supply, the same supply whose contamination profile was documented in Article 4 of this series.

As established in that investigation, UK tap water contains PFAS compounds at levels for which no statutory maximum exists in British law, with the Drinking Water Inspectorate’s guidance value of 100 nanograms per litre being 25 times more lenient than the United States EPA standard [22]. Pharmaceutical residues including antidepressants, contraceptive hormones and anti-epileptic drugs pass through wastewater treatment and into drinking water supplies but are not routinely tested for [22]. Microplastics are present at an average of 57 particles per litre with no monitoring standard [22]. And trihalomethanes, carcinogenic byproducts of chlorine disinfection, are permitted up to 100 micrograms per litre [22].

Large breweries use reverse osmosis and activated carbon filtration to treat their water, and many adjust the mineral profile to achieve desired brewing characteristics. These processes are effective at removing some contaminants. But there is no regulatory requirement for breweries to test their production water for PFAS, pharmaceutical residues or microplastics, and no requirement to test the finished product for these compounds. PFAS, in particular, are resistant to conventional water treatment and can persist through reverse osmosis at reduced but not eliminated concentrations.

In high gravity brewing, the water used for post-fermentation dilution must be of the highest quality: sterile, de-oxygenated and carbonated to match the beer [18]. But “highest quality” in the brewing context refers to microbiological safety, dissolved oxygen content and mineral composition. It does not refer to PFAS, pharmaceutical residues or microplastics. When a brewery dilutes a concentrated beer with 30 to 50 per cent treated mains water, it is adding whatever those water treatment processes failed to remove. No one monitors this. No one tests the finished product. No one is required to.

Part Six: Glyphosate - The Weedkiller in Your Pint

In 2019, the US Public Interest Research Group tested 20 beer and wine brands and found glyphosate, the active ingredient in Roundup weedkiller, in 19 of 20 samples [23]. Popular beer brands including Coors Light, Miller Lite and Budweiser contained concentrations above 25 parts per billion [23]. Guinness and Heineken contained approximately 20 ppb [24]. Stella Artois and Samuel Smith’s Organic both tested positive, though at lower concentrations [24]. Only one product, Peak Beer Organic IPA, contained no detectable glyphosate [23].

A 2016 study in Germany found glyphosate residues in every beer sample tested [23]. A 2018 study in Latvia reached similar conclusions [23]. A 2024 study published in Food Additives and Contaminants tracked 17 pesticides through the brewing process and found that while most non-polar pesticides were retained in spent grain, glyphosate behaved differently: more than 80 per cent of glyphosate residues transferred through into the sweet wort and subsequently into the finished beer [25].

Glyphosate was classified as a “probable carcinogen” by the World Health Organisation’s International Agency for Research on Cancer in 2015 [23]. California agreed, adding it to the state’s list of known carcinogens in 2017 [23]. Research has found that those exposed to glyphosate are 41 per cent more likely to develop non-Hodgkin lymphoma [24]. One study found that glyphosate at concentrations as low as 1 part per trillion, far below the levels detected in beer, could stimulate the growth of breast cancer cells and disrupt the endocrine system [23].

The brewing industry does not want glyphosate on its raw materials. The Brewers Association in the United States opposes its use on barley. But glyphosate is the most widely used herbicide in the world, sprayed on the cereal crops from which brewing grains are sourced, and its residues survive the malting and brewing process. In the UK, where no ingredient list is required on beer and no routine testing for pesticide residues in finished beer is mandated, the consumer has no way to know whether their pint contains glyphosate residues. The regulatory framework does not require the question to be asked.

Part Seven: The Brewery That Owns Your Pub

The degradation of British beer does not occur in isolation. It is part of an industrial structure designed to extract maximum profit from every point in the supply chain, from the grain to the glass.

The UK beer market is dominated by three multinational corporations: AB InBev (owner of Budweiser, Stella Artois, Beck’s and Camden Town Brewery), Heineken (owner of Birra Moretti, Amstel, Foster’s and a controlling interest in Beavertown), and Molson Coors (owner of Carling, Coors, Sharp’s Doom Bar and Aspall) [26]. These three companies, together with Carlsberg Marston’s and Diageo, control the overwhelming majority of draught beer lines in British pubs. Macro breweries held 76.7 per cent of the UK draught beer market in 2024 [27].

Meanwhile, the pubs themselves are disappearing. CAMRA data shows that 1,062 pub businesses across Great Britain closed in 2024, with a further 210 converted to other uses [28]. In the first three months of 2025 alone, 303 more pubs shut their doors [28]. By the end of 2025, analysis by global tax firm Ryan found that pubs liable for business rates had fallen from 38,989 to 38,623, a net loss of 366 pubs, equivalent to one pub every single day [29]. Since the year 2000, more than 15,000 pubs have permanently closed in the UK [30]. The BBPA warned that for every three pounds spent in a pub, one pound goes directly to the tax man [31].

In 2024, 100 small independent breweries closed, according to the Society of Independent Brewers [32]. These are the producers most likely to brew genuine all-malt beer without adjuncts, the businesses whose products represent what beer is supposed to be. They are being crushed by the same cost pressures, duty, energy, raw materials, employer NICs, that the multinational brewers absorb through economies of scale, ABV reductions and ingredient substitution.

The structure is self-reinforcing. The multinationals reduce ABV to save duty. The savings are not passed to pubs or consumers. Small brewers cannot reduce ABV without destroying their products. Pubs close. Small breweries close. The multinationals gain further market share. The consumer has fewer choices, each one thinner, weaker and more industrially produced than the last.

Part Eight: What Germany Requires and Britain Does Not

The contrast with Germany is instructive. The modern German brewing law, the Vorläufiges Deutsches Biergesetz, which replaced the original Reinheitsgebot in 1993, permits only malted barley, wheat, rye, hops, water and yeast in beer [1][33]. No glucose syrup. No maize starch. No rice. No caramel colouring. No foam stabilisers. No processing aids that remain in the finished product. When Corona is sold in Germany, its label is required to disclose its full ingredient list, including the propylene glycol alginate foam stabiliser and ascorbic acid antioxidant that appear on no label in Britain [9].

In 1987, the European Court of Justice ruled that Germany could not refuse imports of beer that did not comply with the Reinheitsgebot, but required that such products carry labels declaring the use of non-conforming ingredients [33]. German consumers could therefore make an informed choice. British consumers cannot, because British law does not require them to be informed.

The EU moved towards mandatory ingredient and nutrition labelling for alcoholic beverages in 2023, requiring wine to carry full ingredient lists from December of that year [34]. Beer was included in the scope of the proposed regulation. Post-Brexit Britain, however, is under no obligation to follow. The UK has taken no steps to require ingredient labelling on beer. The exemption that permits brewers to sell you a product without telling you what is in it remains entirely intact.

Part Nine: What British Consumers Actually Drink in 2026

Consider the pint of mainstream lager purchased in a British pub or from a British supermarket in 2026.

The beer was brewed at high gravity, perhaps 7 or 8 per cent ABV, using a combination of malted barley and glucose syrup or maize starch to provide cheap fermentable sugar. It was fermented, then diluted with de-aerated mains water to reach its target ABV of 3.4 or 4.6 per cent. Colour was corrected in-line. Hop bitterness was added using iso-hop extract. Foam stability was enhanced with propylene glycol alginate. The beer was clarified using isinglass derived from fish swim bladders, or using PVPP, a synthetic polymer. None of these adjuncts, additives or processing aids appear on the label.

The water used, both in brewing and in dilution, was drawn from the mains supply and treated by the brewery. It was not tested for PFAS, pharmaceutical residues or microplastics, because no regulation requires this. The barley from which the malt was made was grown using glyphosate herbicide, residues of which persist through the brewing process into the finished beer. No testing for glyphosate in the finished product is required.

The beer’s ABV has been reduced multiple times over the past decade, from 5.2 per cent to 4.6, or from 4.2 to 3.4, saving the brewer millions of pounds per year in excise duty. These savings have not been passed to the consumer. The price of a pint has risen from approximately £3.50 in 2015 to over £6.00 in many parts of the country. What you receive in 2026 is materially weaker, contains more adjuncts, and costs significantly more than what you received a decade ago.

The company that brewed your beer is a multinational corporation, Belgian, Dutch, American or Canadian-Danish, that has used its scale to dominate draught lines, acquire or undercut independent competitors, and lobby government on duty structures that disproportionately reward ABV reductions. Meanwhile, the pub you are drinking in is statistically endangered: one disappears from the British landscape every day, and another 378 are projected to close this year [30].

The regulatory framework that permits all of this requires the brewer to tell you precisely three things: the name of the product, its ABV, and its volume. Everything else, what is in it, how it was made, what was added, what was removed, what contaminants it carries, is entirely at the brewer’s discretion. Most choose not to disclose.

The Cumulative Deception

Every ABV reduction has been framed as a response to consumer demand for moderation. Every reformulation has been described as maintaining “the same great taste.” Every ingredient substitution has been justified by market pressures. Every year, the beer gets weaker, thinner, more industrial, and more expensive.

In Germany, beer drinkers know exactly what is in their glass, because the law requires it and the culture demands it. In Belgium, a pilsner is brewed to 5.2 per cent because that is the standard and the consumer expects it. In the Czech Republic, brewers compete on the quality of their ingredients. In Britain, brewers compete on the efficiency of their cost-cutting, protected by a regulatory framework that does not require them to disclose what they have done.

The British consumer deserves to know what is in their beer. They deserve ingredient lists. They deserve to know whether their pint was brewed from malt or from glucose syrup. They deserve to know whether the foam on their glass is natural or chemical. They deserve to know whether glyphosate residues are present. They deserve to know that the water used to dilute their beer carries contaminants that no one monitors and no one tests for.

They deserve, at a minimum, the same transparency that a German consumer has enjoyed by right for more than five hundred years.

Until that transparency exists, the British pint will remain what it has become: a product manufactured to the minimum standard that the market will tolerate, by companies with no obligation to disclose what that standard actually is, sold to consumers who have no way to tell the difference.

Call to Action

This series does not simply document failure. It demands specific remedies. On beer, the following reforms are necessary, achievable, and overdue:

1. Mandatory ingredient labelling on all beer and alcoholic beverages sold in the United Kingdom.

The exemption that permits alcoholic beverages above 1.2% ABV to be sold without an ingredients list is indefensible. The EU moved to require ingredient labelling on wine from December 2023 and included beer in its regulatory scope. Post-Brexit Britain has taken no equivalent step. Every packaged food product in a British supermarket must declare its ingredients. Beer, a product consumed by tens of millions of people every week, is not required to declare whether it contains glucose syrup, maize starch, propylene glycol alginate, isinglass, caramel colouring or any other adjunct or processing aid. This exemption should be abolished. If Germany can require Corona to declare its foam stabiliser on the label, Britain can require the same of every beer sold on its shelves.

2. Mandatory nutrition declarations on all alcoholic beverages, including calorie content, sugar and carbohydrate levels.

A consumer purchasing a soft drink, a chocolate bar or a bag of crisps receives a full nutritional breakdown. A consumer purchasing a pint of lager, which may contain more calories than any of those products, receives nothing. The same Food Information Regulations that mandate nutritional labelling on every other consumable product should apply to beer, wine and spirits without exception. The alcohol industry's exemption from nutritional transparency has no scientific, ethical or consumer-protection basis. It exists because the industry lobbied to retain it. It should end.

3. A statutory requirement that declared ABV reflects the actual brewed strength of the product, with a maximum tolerance of 0.3 percentage points.

The current labelling tolerance of plus or minus 0.5% ABV for beers between 1.2% and 5.5% is an invitation to deceive. Molson Coors brewed Carling at 3.7% while labelling it at 4.0% for at least five years, and the law permitted it. A beer labelled at 4.0% should contain beer brewed to 4.0%, not beer brewed to 7% and diluted with water to 3.7%. The tolerance should be tightened to 0.3 percentage points, and any brewery that systematically brews below its declared ABV should be required to update its labelling within 90 days or face enforcement action.

4. Mandatory disclosure of high gravity brewing and post-fermentation dilution on all products where the practice is used.

If a beer has been brewed at a higher concentration and diluted with water to reach its target ABV, the consumer should know. A simple mandatory declaration, "Brewed at high gravity and diluted to target strength," would allow consumers to distinguish between a beer brewed to its declared strength and one that has been watered down. This is not a radical proposal. It is the minimum transparency owed to a person paying over six pounds for a pint.

5. Mandatory testing and disclosure of glyphosate residues in finished beer.

Peer-reviewed research has found glyphosate, classified as a probable carcinogen by the WHO's International Agency for Research on Cancer, in 19 of 20 beer brands tested, with more than 80 per cent of glyphosate residues in barley transferring through the brewing process into the finished product. No UK regulation requires breweries to test for glyphosate in their beer, and no labelling requirement exists to disclose its presence. A mandatory annual testing regime for glyphosate and other pesticide residues in finished beer should be introduced, with results published and maximum residue limits set in line with international best practice. The consumer has a right to know whether their pint contains a probable carcinogen. The industry's preference not to ask the question is not a substitute for an answer.

6. Mandatory testing of brewing water and dilution water for PFAS, pharmaceutical residues and microplastics.

Water constitutes 90 to 95 per cent of finished beer. In high gravity brewing, up to 50 per cent of the finished product may be water added after fermentation. That water is drawn from mains supplies carrying contaminants documented in Article 4 of this series, including PFAS for which Britain has no statutory legal limit, pharmaceutical residues that treatment plants were never designed to remove, and microplastics for which no monitoring standard exists. Breweries should be required to test their production and dilution water for these contaminants and to publish the results. A product that is 95 per cent water should be held to the same transparency standards as the water itself.

7. A review of alcohol duty structures to prevent ABV reductions being used as a stealth tax saving passed entirely to shareholders rather than consumers.

The 2023 duty restructure created a powerful financial incentive for breweries to reduce ABV to 3.4% or below, with potential savings of tens of millions of pounds per year for the largest brands. Every major lager brand in Britain has exploited this threshold. Not one has passed the saving to the consumer through a price reduction. The Treasury should require that where a brewery reduces ABV specifically to exploit a duty band threshold, at least 50 per cent of the duty saving is reflected in the retail price, or the product must carry a clear declaration that its ABV has been reduced and the reason for the reduction. Duty policy designed to encourage moderation should not function as a mechanism for multinational brewers to increase margins while delivering a weaker product at the same price.
