Cream ale: Cream ale is a style of American and Canadian beer, of which examples are often light in color and are well attenuated.  First crafted in the mid-1800s at various breweries in the United States, and in Canadian breweries such as Sleeman, cream ale remained a very localized form with different styles until the early 20th century.  During Prohibition in the United States, a great number of Canadian brewers took up brewing cream ale, refining it to some degree.  Following the end of Prohibition in the United States, cream ale from Canada became popular and the style was produced anew in both nations.

Korn (liquor): Korn (from German, "grain", "Brit. " "corn") also known as Kornbrand or Kornbranntwein (English: "grain brandy" or "grain spirit"), is a German colorless distilled beverage produced from fermented cereal grain seed.  In the production of "Korn" only the cereal grain types rye, wheat, barley, oat and buckwheat are permissible.  Most of the production is based on rye or wheat; barley and buckwheat are rarely used.  Barley is mainly used to obtain the required malt for the brewing process.  The addition of food color, flavorings, or sweeteners is not permitted.  Korn differs from vodka in that it is distilled to lower alcoholic proofs and less rigorously filtered, which leaves more of the cereal grain flavor in the finished spirit.

Kentucky common beer: Kentucky Common Beer is a once-popular style of ale from the area in and around Louisville, Kentucky from the 1850s until Prohibition.  This style is rarely brewed commercially today.  It was also locally known as "Dark Cream Common Beer", "Cream Beer" or "Common Beer".  The beer was top-fermented and wasn't krausened, i.e., it was fermented once and sent out for sale which meant the gravity would be moderate, the carbonation low and the taste full and sweetish.  Like cream ale, it was consumed fresh, usually as draught beer.  In 1913 it was estimated that 80% of the beer consumed in Louisville was of this type.  Many local breweries made this style of beer exclusively.
