Keystone beer is a product of the Molson Coors Beverage Company in Golden, Colorado. It was first introduced in Chico, California in September 1989. Keystone Ice can be found in canned, kegged, and occasionally, bottled form, with 5.9% ABV. Keystone Light has a 4.13% ABV; roughly equal to other macro "light" brews. Keystone is a primary sponsor for Austin Cindric’s number 2 car in the NASCAR Cup Series.

Raspberry - Lime The "Light" and "Ice" versions of the beer are far more prevalent and readily available for retail across the United States. Though Keystone Premium exists, it appears much less than its "Light" variety on liquor store shelves. "Dry" and "Amber Light" varieties were discontinued in the late 90s. Recently, a new variety of Keystone, V9, has been introduced to Puerto Rico by a licensed distributor there, V. Suárez & Co. Inc., of Guaynabo, intended to be sold cheaply. The can is black with a blue "V9" and is labeled as 5.9% alc./vol. In the province of Ontario (and most of Canada), Keystone Light is available in bottles, cans, and tall cans at 4.0% A.B.V. and featuring a 'near-discount' price. Nutrition information Marketing The advertising slogan in 2007 for Keystone was "Always Smooth, Even When You're Not." The official slogan was formerly "All Stones Must Be Thrown", and it was marketed as "bottled beer taste in a can" (due, according to Coors, to their use of specially lined cans). Another slogan used for Keystone Light called it the "Never Bitter Beer", with commercials touting it as a remedy for "Bitter Beer Face". The commercial theme in the early 90s was "Wouldn't it be great if..." followed by beer-drinker fantasies, concluding with "and they served beer, really great beer like Keystone
