Product title: Pyramid I Love Beer - I Love Beer Poster - 30.5x91.5cm
Product description: Beer is the world's most widely consumed alcoholic beverage; it is the third-most popular drink overall after water and tea. It is thought by some to be the oldest fermented beverage. Beer is produced by the saccharification of starch and fermentation of the resulting sugar. The starch and saccharification enzymes are often derived from malted cereal grains most commonly malted barley and malted wheat. Unmalted maize and rice are widely used adjuncts to lighten the flavour because of their lower cost. The preparation of beer is called brewing. Most beer is flavoured with hops which add bitterness and act as a natural preservative though other flavourings such as herbs or fruit may occasionally be included.
