bitterness American Society of Brewing Chemists European Brewery Convention ale International Bitterness Units scale
Beer is measured and assessed by colour, by strength and by bitterness. The perceived bitterness is measured by the International Bitterness Units scale (IBU), defined in co-operation between the American Society of Brewing Chemists and the European Brewery Convention. The international scale was a development of the European Bitterness Units scale, often abbreviated as EBU, and the bitterness values should be identical.
