Top Definition
Keystone beer is a product of the Coors Brewing Company in Golden, Colorado. It was first introduced in Chico, California in September of 1989. Due to its relatively low price, it is popular among college-aged individuals. Keystone can be found in can, keg, and occasionally bottled form.

Keystone Light is always smooth. It was voted the best Light beer in Point Pleasant NJ 05, 06, 07 and is the front runner for 08. Keystone Light is Coors light's younger brother. Keystone Light kicks ass.
