IBU = International Bitterness Units. This is a scale of bitterness from 0 to 100. Bitterness is perceived differently by people and the IBU number shows the general direction: the higher the IBU, the more bitterness the beer contains.
OG = Original gravity. It is indicated in the form of a three- or four-digit number, by which amateurs determine whether the beer is dense or not.
EBC = (European Brewing Convention) - brewing standards on European level established by the convention of European brewers. This abbreviation mainly refers to the intensity of the malt color.
American Pale Ale is similar to IPA but more restrained in bitterness and it should have a good balance between malt and hops. APA has a pleasant malt base with light sweetness and caramel tones, while its aroma has tones of citrus and pine needles specific to traditional American hops.
