Out of all the wine games I’ve learned about over the years this is by far the best. My wife and I decided to call it “wine war” and have since had 6 wine wars at our home. Each being a big hit. Here’s how it’s played:
First, decide if it’s going to be red or white wine. You can only do one or the other. Then, invite over 6-12 friends/couples. Each person/couple brings 2 IDENTICAL bottles of red or white. Take 1 of the bottles and put it somewhere safe. Then, take the other bottle and wrap it up with a brown bag, foil, or something that completely conceals the body and label. Then label it by number.
Once everyone is there and the bottles are labeled, pour each of your guests a small pour of each wine, one at a time. Each guest will judge the wines one at a time in 2 parts: Nose and mouth, by a point system. (We used numbers 1-5, 5 being highest) You’ll need to provide a score sheet. We made our own.
Depending on how many guests you have, it will take time to taste all the wines and people will begin to get a little tipsy, so it’s a good idea to provide water, cheeses, fruits, charcuterie, bread, ect to help the buzz and palette.
After all the wines have been tasted, the host will tally up the scores. The person/couple with the highest score keeps ALL of the unopened bottles.
Best. Game. Ever.
Some advice: You can play with the rules for your specific party. For example, we did a party where the $$ cap was $15.00 (one friend who knew nothing about wine brought Charles Shaw…. and it placed 5th out of 13).
We had an all cabernet wine war, a rosé wine war, and a riesling wine war. It’s a good idea to buy a 1oz wine pourer. It keeps folks from getting too hammered. A VERY good rule is to outlaw screw tops. We had a situation where one of our guests cheated when he recognized his wine by the unconcealed screw top, and voted himself up, winning by 2 points. In all fairness, he copped to it 
I hope this sounds like fun to my fellow wine lovers! If you think of any other wine games or ideas to improve or improvise the game please post em!
