We are celebrating 500 years of Reinheitsgebot with this very unique sour ale, a collaboration with the good Germans from Buddelship. This 'impure' beer is full of oats, wheat, rye and barley, and was soured with fresh sauerkraut infused with mango and pineapple. It may not abide with the German purity laws, but remember, reines Bier gefährdet die Gesundheit.
