Osmos ale house3/7/2023 ![]() Some hop volatiles will be lost by boiling along with higher alcohols and aldehydes. ![]() (7) Following a normal fermentation, ethanol can be boiled from the finished beer at temperatures above ethanol’s boiling point of 173.5 oF (78.6 oC) and below the boiling point of water for a minimum of 30 min. Another modification includes (6) interrupting fermentation when the desired gravity and alcohol content are reached via pasteurization or crash cooling or removal of yeast from beer or beer from yeast as in immobilized yeast fermentations. Beers produced in this manner are often reported as having a “worty” flavor character thought to be caused by aldehydes, such as 3-methylthiopropionaldehyde. Several NA beers in the global marketplace are even specifically marketed for dogs.Īlcohol can be reduced and NA beer produced by modifying many different parts of the brewing process singly or in combination, as follows: (1) limiting the malt/water ratio in mashing to yield a calculated lower original gravity and subsequent alcohol level (2) using lower fermentable brewing materials to retain original gravity, yet yield higher finished beer dextrins with lower ethanol (3) controlling the dextrin content by warmer infusion mashing in the 70 oC–80 oC (158☏–176☏) range, which inactivates heat-sensitive enzymes like beta-amylase and slows the conversion of starch dextrins to maltose, thereby lowering the fermentability of wort (4) fermenting the “second runnings” from a stronger beer mash (e.g., Imperial or Scotch Ale) and (5) using the “cold contact” method of fermentation by pitching brewer’s yeast into wort at or near freezing temperatures, effectively limiting fermentation but allowing some beer flavor development. Spain has recently reported alcohol-free beer sales as 8% of total beer sales. Recently, stricter drunk-driving law enforcement and increasing awareness of the reduced calorie content of NA beers (generally half of regular alcohol beers) have resulted in higher volume sales in some markets. ![]() In the United States, NA beers are produced exclusively by large mass-market brewers. Many brewers think of NA beer production and sales as part of their overall corporate citizenship effort because profitability can be lower for these products as a result of higher equipment and energy costs. There are hundreds of non-alcoholic and alcohol-free beers in the global marketplace today, currently representing less than 1% of total worldwide beer sales. Although there is no global agreement for reduced alcohol beer or wine, the worldwide codex standards for ethanol in some fruit juices, soft drinks, and baked goods are 0.3% to 1.0% ABV maximum hence, interestingly, these products may contain equal or higher levels of alcohol derived from the use of flavoring extracts or natural fermentation than some categories of beer and wine. The European Union standard is wider than that of the United States or UK because alcohol-free applies to all beverages containing less than 0.5% ABV. Beverages labeled as dealcoholized, alcohol-removed, or non-alcoholic may not contain more than 0.5% ABV and those labeled low alcohol may not exceed 1.2% ABV. In the United Kingdom, alcohol-free or zero- alcohol beverages may contain measurable alcohol up to 0.05% ABV. The term “alcohol-free” may be used in the United States only when the product contains no detectable alcohol. Food and Drug Administration does not consider the terms “non-alcoholic” and “alcohol-free” synonymous. ![]() In the United States, the term “non-intoxicating” was applied to all beverages with less than 0.5% ABV during Prohibition and has since morphed into “non-alcoholic.” The U.S. In the United States, although these products are colloquially called non-alcoholic beer, the actual labels read “non-alcoholic malt beverage” or “non-alcoholic brew.” These NA products may contain up to 0.5% alcohol by volume (ABV), although there are global differences that can lead to confusion. Technically speaking, there is no such thing as non-alcoholic beer because beer contains alcohol by definition. Although the name might lead one to believe that a non-alcoholic beverage contains no measurable alcohol, this is not true. Non-Alcoholic “Beer,” also called NA, low-alcohol, near beer, small beer, or small ale, is a malt beverage with very low alcoholic content.
