The subject of wines is full of a ton of hooey. Find wines that taste good to you and ignore all the arrogant BS. All this wine tasting BS is just an attempt to make getting hammered a respectable pastime.
If you want to get rid of talkative wine snobs, announce that wine is just fancy grape juice. Then mix 2/3rds Wal-Mart box Chard with enough substandard Merlot to produce a pleasing ruby color, add a few ice cubes, swirl the glass as you hold it to a bright light and wax enthusiast about the color and aroma, point out the skinny ‘legs’ and fruity taste. Offer them a taste of yours and a full glass if they love it as much as your dog, poor some in his bowl, then sit down and tune in to Law & Order reruns or Forensic Files. Wine snobs will suddenly remember previous obligations.
