The Boston Beer Company has teamed up with Germany's Weihenstephan Brewery to launch a line of "Champagne-like" beers for next spring.

Boston's Samuel Adams brand team and Weihenstephan have been working on the new beer line for around two years, the company said yesterday (22 October).

The yet-to-be-named pale brew is expected to debut in the US and Germany next spring in cork-finished bottles. The "Champagne-like" beer will contain more than 10% alcohol by volume.

"The Weihenstephan Brewery is a mecca for brewers and people around the world who are passionate about beer and brewing," said Jim Koch, founder and brewer of Samuel Adams beers.

"It is a great honour to work together on this mission to explore the limits of the Reinheitsgebot [Germany beer purity law] and to brew a beer that represents the platinum standard in the art of brewing."

The Reinheitsgebot, sometimes called the "German Beer Purity Law", is a regulation concerning the production of beer in Germany.

In the original text, the only ingredients that could be used in the production of beer were water, barley, and hops. The law has since been repealed but many German beers still declare that they abide by the rule for marketing purposes.

The new beer will be available globally in the spring of 2010.

Last month, The Boston Beer Co launched a Harvest Collection for its Samuel Adams brand.

Featuring six 'craft' beers and including a new style; Samuel Adams Dunkelweizen, the pack offers consumers a selection of beer styles reflective of the autumn season.
