They Don't Actually Call It "Extreme," But At 150 Clams/Bottle ... (UPDATED)

Samuel Adams Introduces Extreme Beer
The new brew from Samuel Adams has the highest alcohol content of any beer on the market, 27 percent.

Boston, MASS-- It's Sam Adams with quite a punch -- and a price to match. The new brew from Samuel Adams has the highest alcohol content of any beer on the market, 27 percent. It's also banned in 13 states because of the alcohol. It's called Utopias and it sells for about 150 bucks a bottle. It has a cognac-like hit and is served at room temperature. Jim Koch, founder and owner of the Boston Beer Co., says they're trying to push the envelope. He says the Utopias are aged for 15 years and should be sipped like champagne.
