Sour
From Home Brewing Wiki
(Redirected from Acidic)
Sour or acidic flavor in beer is nearly always caused by bacterial infection.
There are two major types of bacteria used for souring beer. Lactic acid gives a smooth sourness that can be reminiscent of yogurt. Acetic acid gives a sharper, tangier bitterness. See the individual entries for each type of acid for more information.
