Valentine’s Day is upon us, with its chocolates, flowers and other romantic goodies. Thankfully, for millions of partner-less people, Feb. 14 is also Singles Awareness Day (SAD), an anti-Valentine’s affair that does away with all that mushy stuff. This year, the bitter masses can enjoy the Don’t Be Bitter(s) tasting event in Napa, featuring an array of the best bitter liqueurs from Italy. Once you find your favorite bitter, you can turn it into a mini cocktail and toast to singlehood on Wednesday, Feb. 14, at the Culinary Institute of America at Copia, 500 First St., Napa. 6pm. $35. 707.967.2530.
