14 days ago I put 14 pounds of honey and some OJ and some lemonjuice and some raisins in a mead batch of 6 gallons. I used a starter with oj and used nottingham yeast. It has reached 10% alcohol now, but I want it up to 12%.. It took that last week to get it from 9 to 10%. Is there anything I can do to speed things along? There is enough sugars in it still so its not that. Input anyone?
