I bottled mine over Christmas, got loads in the cupboard now, although I don't think you can ever have too much. I try to make more than i need, that way some gets 'forgotten' at the back of the cupboard for a few years all being well and is a prize when it is refound!
I made one demi-john with 3 litres of vodka and damsons off my tree as a trial this year, and I have to say that it is on a par, or maybe even has the edge over the sloes ... time will tell though
I still have about 8 kilos of sloes in the freezer ready to do another batch too
