In reply to Jim Walton:
Totally fill an empty 5ltr spring water container or similar with sloes, (after removing leaves, spiders etc) no need to jab or slit them at all, top up with cheap gin, expensive stuff seems to make no difference whatsoever, leave until around christmas with the cap slightly loose to allow gasses to escape, I dont add any sugar at all, but that's just how I prefer it, decant through a filter, this is the way of making it an old guy recommended years ago, and it tastes way better than the overly sweet shop bought Gordons rubbish I tasted! there will always be at least one grub of some sort floating in the stuff, this is normal, it died happy, and will not harm you in any way.
