I tried making 2.5 gallons of hard cider and basically followed the Brulosphy recipe. It was for a 5 gallon batch and called for 2 12 oz cans of concentrate after fermentation and chemical stabilization. I used 1 can of concentrate. My cider is too sweet. Is there anything I can do at this point? (I now remember that I did not stir in the concentrate, I just added the cider to a keg with the concentrate already in it.)
