Tank 18 (1345 Howard Street at Dore), SoMa’s newest urban winery, is doing a Sustainable Bottling party on Saturday, February 16. The deal is pretty simple: Bring your own washed-out wine bottle and get it filled with their new Petite Syrah for $7.99, or buy it already bottled for $9.99. You can watch the bottling in process in the video by Seasons of Wine, and in addition to being a good deal on a decent bottle of wine, you can get an education in the mechanics of bottling while you’re at it. For those who like to shop in bulk, you can drop off a case or more of bottles on Friday and pick them up filled on Saturday. Doors open at 10 a.m. and they’ll go until they’re sold out. Also, from 11:30 a.m. to 4 p.m., The Old Port Lobster Shack will be there serving lobster rolls.
