Additional Notes:
This American-born regional style proliferated around Louisville, Kentucky, from the Civil War era until Prohibition. Corn grits or flakes were commonly used at a rate or 25-35% of the total grist. Minerally attributes resulted from the use of hard brewing water. These beers were consumed very young, going from brewhouse to consumer in as little as one week. Early 20th century brewing literature mentions a slight tartness developing during fermentation as a characteristic attribute of this style. If tartness is present in modern versions, it should be at very low levels.
