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.

Similar to how every cloud has a silver lining, every picture of drunks has a can of Keystone light in it.
Tammy: My picture doesn't have Keystone Lighting in it because it's just of my face.

Mark: Yeah but you can see a reflection of a can in your pupils, and your face says it all.
