Ananova:

A brewery in the States has launched the world's strongest beer.

The drink - at 25% alcohol - is six times more powerful than a normal beer and twice the strength of a bottle of wine.

And at £56 a bottle, Samuel Adams Utopias is also among the world's most expensive.

Just 8,000 of the limited edition 24 oz tipple, sold in a copper kettle, have been brewed by the Boston Beer Company.

Brewery founder Jim Koch said the beer was designed to be enjoyed slowly as an after dinner tipple.

He said: "We are passionate about brewing quality, one-of-a-kind beer that amazes beer lovers and aficionados alike."
