I love ginger and one easy one is ginger ale. Simply boiled ginger with sugar and after it cools add baker's yeast, bottle and let it ferment a few days. I started out using wine yeasts, but after it occurred to me that it was only going to ferment for 2-3 days (after that the yeast eats all the sugar and you lose a lot of the flavor) so I just started using whatever baking yeast I had on hand.

Deliciously alcoholic.
