Brewing is used to convert the starches in the malt to sugar, which is then usable by the yeast later in the brewing process. Doing the latter rest at the lower end of the range favours β-amylase enzymes, producing more low-order sugars like maltotriose, maltose, and glucose which are more fermentable by the yeast. This in turn creates a beer lower in body and higher in alcohol. A rest closer to the higher end of the range favours α-amylase enzymes, creating more higher-order sugars and dextrins which are less fermentable by the yeast, so a fuller-bodied beer with less alcohol is
Low-alcohol beer in craft non-alcoholic beer production. Beers that are labeled "non-alcoholic" still contain a very small amount of alcohol. Thus, some US states require the purchaser to be of a legal drinking age. Exceptions include: According to the Birmingham Beverage Company, the brewing process of traditional brews consists of eight basic steps, nine for brewing non-alcoholic brews. Low-alcohol beer starts out as regular alcoholic beer, which is then cooked in order to evaporate the alcohol. This is possible because alcohol is more volatile than water, so it is easier to boil off. The alcohol is allowed to escape and the remaining
