Notes

Overall Impression:
A darker-colored, light-flavored, malt-accented beer with a dry finish and interesting character malt flavors. Refreshing due to its high carbonation and mild flavors, and highly sessionable due to being served very fresh and with restrained alcohol levels.

Aroma:
Low to medium grainy, corn-like or sweet maltiness with a low toast, biscuity-grainy, bready, or caramel malt accent. Medium to moderately-low hop aroma, usually floral or spicy in character. Clean fermentation character, with possible faint berry ester. Low levels of DMS are acceptable. No sourness. Malt-forward in the balance.

Appearance:
Amber-orange to light brown in color. Typically, clear but may have some light haze due to limited conditioning. Foam stand may not be long lasting, and is usually white to beige in color.

Flavor:
Moderate grainy-sweet maltiness with low to medium-low caramel, toffee, bready, and/or biscuity notes. Generally light palate flavors typical of adjunct beers; a low grainy, corn-like sweetness is common. Medium to low floral or spicy hop flavor. Medium to low hop bitterness, which should neither be coarse nor have a harsh aftertaste. May exhibit light fruitiness. Balance in the finish is towards the malt. May have a lightly flinty or minerally-sulfate flavor in the finish. The finish is dry, including the contributions of roasted grains and minerals. No sourness.

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

Comments:
Modern characterizations of the style often mention a lactic sourness or sour mashing, but extensive brewing records from the larger breweries at the turn of the century have no indication of long acid rests, sour mashing, or extensive conditioning. This is likely a modern homebrewer invention, based on the supposition that since indigenous Bourbon distillers used a sour mash, beer brewers must also have used this process. No contemporaneous records indicate sour mashing or that the beer had a sour profile; rather the opposite, that the beer was brewed as an inexpensive, present-use ale. Enter soured versions in American Wild Ale.

History:
A true American original style, Kentucky Common was almost exclusively produced and sold around the Louisville Kentucky metropolitan area from some time after the Civil War up to Prohibition. Its hallmark was that it was inexpensive and quickly produced, typically 6 to 8 days from mash to delivery. The beer was racked into barrels while actively fermenting (1.020 – 1.022) and tightly bunged to allow carbonation in the saloon cellar. There is some speculation that it was a variant of the lighter common or cream ale produced throughout much of the East prior to the Civil War and that the darker grains were added by the mostly Germanic brewers to help acidify the typical carbonate water of the Louisville area, or that they preferred darker colored beers. Up until the late 19th century, Kentucky Common was not brewed in the summer months unless cellars, usually used for malting, were used for fermentation. With the advent of ice machines, the larger breweries were able to brew year-round. In the period from 1900 to prohibition, about 75% of the beer sold in the Louisville area was Kentucky Common. With prohibition, the style died completely as the few larger breweries that survived were almost exclusively lager producers.

Characteristic Ingredients:
Six-row barley malt was used with 35% corn grits to dilute the excessive protein levels along with 1 to 2% each caramel and black malt. Native American hops, usually about .2 pounds per barrel of Western hops for bittering and a similar amount of New York hops (such as Clusters) for flavor (15 minutes prior to knock out). Imported continental Saazer-type hops (.1 pounds per barrel) were added at knock out for aroma. Water in the Louisville area was typically moderate to high in carbonates. Mash water was often pre-boiled to precipitate the carbonate and Gypsum was commonly added. Considering the time from mash in to kegging for delivery was typically 6 to 8 days, clearly aggressive top-fermenting yeasts was used.

Style Comparison:
Like a darker-colored cream ale emphasizing corn, but with some light character malt flavor. Malt flavors and balance are probably closest to modern adjunct-driven international amber or dark lagers, Irish red ales, or Belgian pale ales.
