Which is why we're pleased that San Francisco has delivered up at least one solution, in the form of Golden Star Tea. It looks like champagne. It tastes like champagne (the fermentation process involves champagne yeast.) It even costs as much as champagne, so your non-boozing guests won't feel all low-status. (Clarification: it's as expensive as the bad stuff. Compared to the good stuff it's a bargain.) Rigorous testing recently conducted under highly scientific conditions have shown it to be delicious with Indian food. And it's made by locals, so one can feel all smug and carbon-neutral for supporting the region's jasmine silver needle carbonated tea economy. I know. It's a particularly Bay Area kind of smug, and doesn't come easily at first. But it starts to feel natural after awhile.
Find Golden Star Tea at Whole Foods and other stores, and on restaurant bev menus.
