I made red vinegar about 35 years ago. It wasn't good vinegar. It wasn't even supposed to be vinegar; it came from a kit, complete with cask, liner, yeast and grape mash. You were to have a potable libation in a couple or three weeks I guess. I just got vinegar (did I say that?) It wasn't good vinegar, but it cleaned out the plumbing...well, behind every cloud, etc.--Happy 2006, John
