Spike Your Juice is a simple introduction to home fermentation. The kit comes with enough yeast packets for six batches, an airlock with rubber stopper, and clear instructions. To brew a batch of alcoholic juice, add one yeast pack to a 64oz bottle of juice (such as grape or cranberry), shake, stopper with the water-filled airlock valve, and wait 48 hours. The yeast will digest the sugar, producing alcohol and carbonation. Tasty, fizzy, and tipsy fun!
