Spike Your Juice is a DIY federweisser kit that turns a bottle of juice into a fizzy alcoholic drink. For $10, you get six packets of Spike Your Juice's proprietary yeast blend, enough to make six 64-ounce bottles, plus a bottle stopper and an airlock gadget to keep your homemade glug free of any contaminants while it's fermenting. Mix in the yeast packet, stop up the bottle, stick your juice in the fridge, and two days later you have booze! You can drink it then or keep letting it ferment; the alcohol content goes up to 14 percent with time.
You can use just about any juice with Spike Your Juice, but apparently the product's group of European founders are currently hot to trot on Ocean Spray's White Cranberry & Peach.
