So I've got a Solomon Grundy Sauvignon Blanc (gallon) kit that's slight past its best before. Rather than ditch it (I reckon it's fine), that's gone in with 1L red grape, 1L pineapple & 1L apple & mango. 6L water 1300G sugar + the usual WoW extras. The kit yeast + a Wilko wine yeast. So I've got a hybrid brew on the go. Half WoW, half kit. It'll be wine but will it past the chief taster? I'll find out in about 6 weeks.
