Medium to low bitterness, no coarse or harsh aftertaste. May exhibit light fruitiness. Balance in the finish is towards the malt, possibly with a lightly flinty or minerallysulfate flavor. The finish is fairly dry. No sourness.

Medium to medium-light body with a relatively soft mouthfeel. Highly carbonated. Can have a creamy texture.

Modern accounts of the style often mention lactic sourness or sour mashing, but brewing records from around 1900 at larger breweries have no indication of long acid rests, sour mashing, or extensive aging. These stories are likely modern homebrewer inventions, theorizing that since local Bourbon distillers used a sour mash, beer brewers must also done so. No records indicate sour mashing or even a sour profile in the beer; rather the opposite, that it was brewed as an inexpensive, present-use ale.

An American original, Kentucky Common was almost exclusively produced and sold around Louisville, Kentucky from some time after the Civil War until Prohibition. It was inexpensive and quickly produced, racked into barrels while actively fermenting, and tightly bunged to allow carbonation in the saloon cellar. Before the style died, it accounted for about 75% of sales around Louisville. Some have speculated it was a dark variant of Cream Ale, created by immigrant Germanic brewers who added darker grains to help acidify the local carbonate water.
