I've made about a half-dozen batches using Listermann's and similar extract kits, but this Christmas a well-meaning family member gave me a Mr.Beer refill kit. The total fermentables come to 2 pounds, rather than the 4 to 6 pounds of the full-sized kits. Should I make a short batch, despite the large airspace that would leave in my fermenter? Or should I toss in some additional extract or corn sugar to make a full five gallons? On the other hand, I could just dump it in with a real ingredient kit to add whatever it can... Any suggestions?
