I am doing a recipe from Charles Papazian's Joy of Homebrewing. Its called Goat Scrotum Ale, and I let my buddy choose what recipe for us to use (thought the name was funny). I made the Wort today and put it in my primary. I put too much malt extract in there. I put 6 lbs of extract instead of 5 lbs. Because of this I put another half gallon-gallon of water in. The gravity is supposed to be at 1.050-1.060, but the gravity on this is 1.090.
What should I do? Is there anything? If not, what happens to this? Will there just be a lot more alcohol in it?
