I agree w/some of the other posters, you can easily complete the quest by giving away or selling the hooch to the vendors. That's what I did, it was fun giving a hooch away to many different people, some gave me back hooch since they were also working on the same quest. An easy quest to complete, I think you've choosen a harder way to do it.
It is very easy to make so I gave mine away too. I'd give everything away if I didn't need currants for some things. I had a great time giving and received as well.
