Beer

Beer is an alcoholic beverage produced by the brewing and fermentation of cereals, most commonly barley. The process involves malting the grain, mashing it with hot water to create a sugary liquid (wort), boiling the wort with hops for flavour and preservation, and finally fermenting the wort with yeast to produce alcohol and carbon dioxide.

Beer is primarily consumed as a beverage. In food manufacturing, it is sometimes used as a flavouring agent, particularly in savoury dishes like stews, marinades, and bread, where its malty, hoppy, and sometimes bitter notes can add depth. It can also act as a leavening agent in baking, contributing to a lighter texture.

Beer is not regulated as a food additive in the UK. Excessive alcohol consumption is linked to numerous health problems, including liver disease, cardiovascular issues, and certain cancers, as stated by the NHS and WHO. The UK's Eatwell Guide advises that to reduce health risks from alcohol, it is safest not to drink more than 14 units per week, if you drink at all. Moderate alcohol consumption may have some debated cardiovascular benefits, but these are outweighed by the risks for many people.
