History

Low-alcoholic brews such as small beer date back at least to

, where they served as a less risky alternative to water (which often was polluted by feces and parasites) and were less expensive than the full strength brews used at festivals. More recently, the temperance movements and the need to avoid alcohol while driving, operating machinery, taking certain medications, etc. led to the development of non-intoxicating beers. In the United States, according to John Naleszkiewicz, non-alcoholic brews were promoted during

, which limited the alcohol content of all beverages to 0.5%. These very-low-alcohol beverages became known as ''tonics'', and many breweries began brewing them in order to stay in business during Prohibition. Since removing the alcohol from the beer requires just one simple extra step, many breweries saw it as an easy change. In 1933, when Prohibition was repealed, breweries simply omitted this extra step. By the 1980s and 1990s, growing concerns about alcoholism led to the growing popularity of "light" beers. In the 2010s, breweries have focused on marketing low-alcohol beers to counter the popularity of homebrew. Declining consumption has also led to the introduction of mass-market non-alcoholic beverages, dubbed "near beer". Low-alcohol and alcohol-free bars and pubs have also been established to cater for drinkers of non-alcoholic beverages, such as Scottish brewer BrewDog's London bar, which opened in early 2020. In the UK, the introduction of a lower rate of beer duty for low-strength beer (of 2.8% ABV or less) in October 2011 spurred many small brewers to revive old styles of small beer and create higher-hopped craft beers at the lower alcohol level to be able to lower the cost of their beer to consumers. At the start of the 21st century, alcohol-free beer has seen a rise in popularity in the Middle East (which now makes up a third of the market). One reason for this is that Islamic scholars issued '' fatawa'' which permitted the consumption of beer as long as large quantities could be consumed without getting drunk.''The Economist''

Pros and cons

Positive features of non-alcoholic brews include the ability to drive after consuming several drinks, the reduction in alcohol-related illness, and less severe hangover symptoms. Low-alcohol and alcohol-free beers are usually lower in calories than equivalent full-strength beers. Some common complaints about non-alcoholic brews include a loss of flavor, addition of one step in the brewing process, sugary taste, and a shorter shelf life. There are also legal implications.

content, and secondarily by reducing the alcohol content, since both carbohydrates and alcohol contribute to the caloric content of beer. Light beers are marketed primarily to drinkers who wish to manage their calorie intake. However, these beers are sometimes criticized for being less flavorful than full-strength beers, being "watered down" (whether in perception or in fact), and thus advertising campaigns for light beers generally advertise their retention of flavor. In Australia, regular beers have approximately 4%-5% ABV, while reduced-alcohol beers have 2.2%–3.2%. In Canada, a reduced-alcohol beer contains 2.6%–4.0% ABV, and an "extra-light" beer contains less than 2.5%. In the United States, most mass-market light beer brands, including

In Sweden, low alcohol beer is either 2.2%, 2.8% or 3.5%, and can be purchased in an ordinary supermarket whereas normal strength beers of above 3.5% must be purchased at '' Systembolaget''. Beer containing 2.8-3.5% ABV (called Folköl or "Peoples' Beer") may be legally sold in any convenience store to people over 18 years of age, whereas stronger beer may only be sold in state-run liquor stores to people older than 20. In addition, businesses selling food for on-premises consumption do not need an alcohol license to serve 3.5% beer. Virtually all major Swedish brewers, and several international ones, in addition to their full-strength beer, make 3.5% folköl versions as well. Beer below or equaling 2.25% ABV (''lättöl'') is not legally subject to age restrictions; however, some stores voluntarily opt out from selling it to minors anyway.


Low-point beer

Low-point beer, which is often known in the United States as "three-two beer" or "3 point 2 brew", is beer that contains 3.2% alcohol by weight (equivalent to about 4% ABV). The term "low-point beer" is unique to the United States, where some states limit the sale of beer, but beers of this type are also available in countries (such as Sweden and Finland) that tax or otherwise regulate beer according to its alcohol content. In the United States, 3.2 beer was the highest alcohol content beer allowed to be produced legally for nine months in 1933. As part of his

By 1921, production of near beer had reached over 300 million US gallons (1 billion L) a year (36 L/s). A popular illegal practice was to add alcohol to near beer. The resulting beverage was known as ''spiked beer'' or ''needle beer'', so called because a needle was used to inject alcohol through the cork of the bottle or keg. Food critic and writer Waverley Root described the common American near beer as "such a wishy-washy, thin, ill-tasting, discouraging sort of slop that it might have been dreamed up by a

In the early 2010s, major breweries began experimenting with mass-market non-alcoholic beers to counter with declining alcohol consumption amid growing preference for craft beer, launching beverages like Anheuser-Busch's Budweiser Prohibition Brew, launched in 2016. A drink similar to "near beer", "bjórlíki" was quite popular in Iceland before alcoholic beer was made legal in 1989. The Icelandic variant normally consisted of a shot of vodka added to a half-a-litre glass of light beer.

Craft non-alcoholic beer

With the global non-alcoholic beer market expected to double by 2024, there has been an increase in breweries producing the product. As more people lean towards non-alcoholic beverages for health reasons, social reasons, or just because they want to enjoy the taste of beer without the effects of alcohol, companies are producing beers that cater to these audiences.


History

Craft non-alcoholic beer began to take off in early 2018, as beer companies slowed down on trying to put as high of an ABV% in their brews as possible, and started producing more sessionable beers. Some beers that are still classified as "alcoholic" can have an ABV of as low as 2.4%, and the companies producing these are still seeing sales. With an ever-growing health conscious market segment, breweries began to produce craft non-alcoholic beers with as little as 10 calories per can, so that those who crave beer can fulfil their cravings without breaking their health resolution.

Production process

According to the Birmingham Beverage Company, the brewing process of traditional brews consists of eight basic steps, nine for brewing non-alcoholic brews. #Malting – Barley is prepared by soaking it in water and allowing the grain to germinate or "sprout". This allows the tough

molecules to be softened and begin conversion to sugars. Next, the sprouts are dried in a kiln; the temperature at which the sprouts are dried will affect the flavor of the finished brew. #Milling – Next the malted grain is ground to a

-like consistency, which allows the sugars and remaining starches to be more easily released when mixed with water. #Mashing – The finely-ground malted grain is mixed with water and pulverized. By pulverizing the slurry, most of the remaining starches are converted to sugars due to enzymes present in the malt, and the sugars then dissolve into the water. The mix is gradually heated to in what is called a mash tun. The slurry is then filtered to remove the majority of particulates. This filtered sugary liquid is called " wort". #Brewing – The wort is brought to a boil for roughly 1–2 hours. During this time, other grains that will contribute flavor, color, and aroma to the brew are added. Boiling allows several chemical reactions to occur and reduces the water content in the wort, condensing it. #Cooling – The wort is filtered to remove the majority of the grains and hops and then immediately cooled to allow the yeast to survive and grow in the next step. #Fermenting – The cooled wort is saturated with air, and yeast is added in the fermentation tank. Different strains of yeast will create different styles of beer. This step takes around ten days. #Maturation – The freshly fermented uncarbonated beer is placed into a conditioning tank and, in a similar process to wine making, is allowed to age. If this step is rushed the beer will have an off flavor (

) that beer experts sometimes refer to as "green beer" because of its resemblance to green apples. During this process of aging, the majority of the residual particulates will settle to the bottom of the tank.
* Between the seventh and eighth steps, the brew can be converted to non-alcoholic beer. #Finishing – Finally, the brewer is ready to finish the beer. The beer is filtered one last time; it is then carbonated and moved into a storage tank for either bottling or kegging. Low- and non-alcohol beer starts out as regular alcoholic beer, which is then processed to remove the alcohol. Older processes simply heat the beer to evaporate most of the alcohol. Since alcohol is more volatile than water, as the beer is heated alcohol boils off first. The alcohol is allowed to escape and the remaining liquid becomes the product, essentially the opposite of the process used to make
distilled beverages Liquor (or a spirit) is an alcoholic drink produced by distillation of grains, fruits, vegetables, or sugar, that have already gone through alcoholic fermentation. Other terms for liquor include: spirit drink, distilled beverage or hard l ...
. Most modern breweries utilize vacuum evaporation to reduce the boiling temperature and maintain flavor. In essence, the beer is placed under a light vacuum to facilitate the alcohol molecules going into the gaseous phase. If a sufficient vacuum is applied, it is not necessary to "cook" the beer at a temperature that destroys the flavor. Some heat must nevertheless be supplied to counter the heat lost to enthalpy of vaporization. A more modern alternative process uses

to avoid heating the product at all. Under pressure, the beer is passed through a polymeric filter with pores small enough that only alcohol and water (and a few volatile acids) can pass through. A syrupy mixture of complex carbohydrates and most of the flavor compounds are retained by the filter. Alcohol is distilled out of the filtered alcohol-water mix using conventional distillation methods. Adding the water and remaining acids back into the syrup left behind on the filter completes the process. Sometimes beer is simply diluted with water to give the desired alcohol level. Once the alcohol is removed, one proceeds with the normal finishing process in which the beer is carbonated and bottled. Newer techniques for making 0.5% non-alcoholic beer would include using special low-sugar grains, yeast which converts less sugar to alcohol or removing sugar from the wort pre-fermentation. These, in addition to limited fermentation, whereby the fermentation process is stopped early, enable craft brewers to produce a 0.5% beer without the expense of having to dealcoholize a beer.


Branding

Many low-alcohol beer brands incorporate the colour blue into the packaging design, including Becks Blue, Heineken 0.0%, Ožujsko Cool and Erdinger Alkoholfrei.
