By gum you are never to old to learn. I can't believe you start Sloe gin the first of September. The sugar, naturally formed in the fruit can't possibly be ready, and to my knowledge the first frost is what makes the berries the best for the Gin or Vodka or Brandy. Unless you are concerned about nicking your fruit, my advise is to leave alone for a while. At this time of year I am doing Blackcurrant Vodka, Blackberry Vodka, Plum gin and a few little other recipes. Would not entertain Sloes until November 1st, Never tried the freezer though??
