I've always toyed with the idea of making my own wine vinegar with the leftover wines I have. (yes, sigh, the unfortunate part of living alone is a lot of leftover wine) So, I now have an Italian crock to make wine vinegar in (see below for a pic of my first attempt) and on order, I have a 5L oak barrel for the same purpose. 2010 will not only be a year of travel for me but it will also be the year of Wine Vinegar! (I'm beginning to think that in a former life I was an Italian farmer's wife)
More posts to come.
UPDATE: I had to switch to a 5 litre oak barrel. I was worried about the brass fittings on the crock above. The Barrel is working out perfectly! Here it is now (1/2011) left, and when I first bought it (1/2010) below (notice that I had the stand upside down!). I've used the vinegar sparingly, but it does have an amazing taste.
