Hop isomerization is a crucial chemical reaction that occurs during wort boiling and is responsible for the majority of the bitterness in beer. Hops contain alpha acids, which are organic acids that are largely insoluble in wort and contribute very little bitterness in their native form. The wort boiling process, which typically lasts 60-90 minutes, provides the heat necessary to isomerize these alpha acids into iso-alpha acids. Isomerization is a chemical process where a molecule is transformed into an isomer, meaning it has the same atoms but a different arrangement, resulting in different properties. In the case of alpha acids....
