Beer style beer differently. Since sugars are converted to alcohol during the process of fermentation, gravity can be used to estimate the final alcohol. In beer brewing, a distinction is made between the "original gravity", the gravity of the wort before fermentation has begun, and the "final gravity" of the product when fermentation has completed. Since the concentration of sugars is directly proportional to the gravity, the original gravity gives a brewer an idea of the potential alcoholic strength of the final product. After fermentation, the differences between the final and original gravities indicates the amount of sugar converted into alcohol, allowing
Women in brewing associated with fertility. From the middle of the 18th century, many women were barred from participating in alcohol production and were relegated to roles as barmaids, pub operators, bottlers or secretaries for breweries. In less industrialized areas, they continued to produce homebrews and traditional alcoholic beverages. From the mid-20th century, women began working as chemists for brewing establishments. Beginning in the 1960s and 1970s, they began re-entering the field as craft brewers. In many Western societies, brewing has been seen as a "man's domain"; however, ethnographic studies and archaeological records indicate that brewing alcohol was primarily an activity engaged in
