Any sugar source not from barley is technically an adjunct according to the German purity law Reinheitsgebet, but who listens to them? Use different honey varietals, brown sugar or Belgian Candi Sugar to add alcohol content and flavor to your heart's desire. Add body without bulk or make that milk stout with unfermentable sugars like Maltodextrine and Lactose. Lighten up your lagers with rice syrup solids, and use the full spectrum of ingredients to make your beer your own. Tell those Germans off!
