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
Women in brewing chewing or malting, is unknown, women in both Japan and Taiwan in the modern age still engage in chewing rice to begin the fermentation process for making alcohol. In Chinese legend, Yi Di, wife of Yu the Great, is credited with making the first alcohol from rice grains.
