Barley is the most common cereal used for beer. This is malted first which involves allowing the barley to star sprouting and then heating it up. The resultant starches are converted to sugars (mainly Maltose) by enzymes in the the grain when raised to a temperature between 60-70C.
Other cereals used include small amounts of wheat in some German style beers, or to improve the head retention in English style beers.
Rice is used in some low quality commercial beers such as Budweiser as it is a cheap way to create more alcohol without any flavour.
