Beer stew is not recommended for young children.
Although the alcohol will partially evaporate during the stewing process, it is not guaranteed that there will be no alcohol left in the stew. Alcohol can cause more serious harm to children than to adults. In mild cases, it can cause adverse reactions in the digestive tract, such as abdominal pain and bloating, and in severe cases, it can induce serious damage such as alcoholic encephalopathy and liver damage, leading to alcoholism.
Beer is an alcoholic beverage made from barley or wheat, after malt fermentation, and its substance is alcohol. Although beer contains some nutritional value, such as 32 calories per 100 milliliters of beer, which contains some free amino acids, vitamins, minerals, etc., but can not hide its essence as an alcoholic beverage.
So to be on the safe side, beer stew is not recommended for young children, and adults are not recommended to consume alcoholic products in any form.
