A collaboration between Weihenstephan and Sam Adams. Available for a limited time only, this innovative new beer style adheres to the rigorous standards of the Reinheitsgebot, the historic German beer purity law that states all beer must be brewed using only four ingredients: malt, hops, water and yeast. Infinium pours out a deep golden color with fine bubbles and has a fruity, elegant aroma. Its crisp acidity gives it a dryness and tartness on the palate that is balanced with a smooth malt body. Infinium is packaged in 750mL cork-finished bottles and contains 10.3 percent alcohol by volume, twice the amount of an average beer.
