A few years ago Wall Street Journal wine columnists Dorothy Gaither and John Brecher started a yearly event called "Open That Bottle Night" that happens on the last Saturday of February. This year it falls on February 23rd.
The purpose of the event is to get people who have held onto a special bottle, for whatever reason, to open it and enjoy it with friends. Even if you aren't holding onto a special bottle, you can buy a wine that you've been craving for a while and share that. So call your friends, see that everyone will be bringing a wine to share, make reservations at your favorite restaurant (check first that you can bring your own wine!) and, by all means, open that bottle!
So...what are you holding onto that you'll be sharing?
