This was my first time making Caribou Slobber(or any 1 gallon kit from NB, I’ve done 5 gallon kits before). It seems pretty short of a gallon(see attachment). Should I be covering the boil for some of the time to conserve water? I started with the 1.25 gallons like it said, so I assumed the extra was for the boil off. Directions never say if you should cover it or not.
Obviously just starting out here, so any tips will help.
