My mead is almost eleven months old. 12 lbs of honey and 10 lbs of blackberries. I am going to bottle it this weekend. I bought 3 lbs of honey to sweeten it. It's a 5 gallon batch that is probably 4 1/2 gallons now due to "tasting" the mead periodically. Currently the mead is dry and a little tart. Should I add all 3 lbs of honey? Any recommendations? I would prefer it on the sweet side, but not too sweet.
