In Tuesday's Open Thread the subject of wine came up and I mentioned that as a crew member at Trader Joe's, we have weekly wine tastings to enhance our product knowledge. Sometimes we taste flights of wine from a particular region, or from a particular grape. Presentations typically focus on the characteristics of the wine, accents, and the background of the vineyard. I don't profess to be an expert but I have learned a few things that might be useful, and/or interesting.
