The Biofuels International website reports that biofuel ethanol production in the European Union (EU) in 2008 increased by 58% compared to the previous year. The major feedstock used is reported to be from cereals. About 63% of the 2.8 billion liters of ethanol produced in 2008 used wheat as the cereal feedstock. Ethanol from maize accounted for 27% , while rye and barley accounted for 4.3% and 3.5% of production, respectively. Triticale (a hybrid of wheat and rye) is also reported as a marginal ethanol feedstock used in Germany.
