For the second consecutive year, The Boston Beer Co. in collaboration with Germany’s Weihenstephan Brewery introduced Infinium, a limited-edition, champagne-like beer. Infinium adheres to the standards of the German Reinheitsgebot purity law, which states that all beer must be brewed using only four ingredients: malt, hops, water and yeast. Infinium is light and dry, yet complex with a sparkling effervescence, the company says. The beer pours out a deep golden color with fine bubbles, and its acidity creates a dry tartness on the palate that is balanced with a smooth malt body, it adds. The brewers enhanced this year's beer by dry hopping with fresh Hallertau Mittelfrueh hops late in the brewing process, imparting a citrusy hop character. Available in 750-ml. cork-finished bottles containing 10.3 percent alcohol by volume, Infinium has a suggested retail price of $19.99.
