Challenged with kombucha by Sable’s Alex Renshaw, Uby Khawaja of Scofflaw turned to fashion designer and Big Star bartender Frog Greishaw, who brews her own from a “mother” (aka a SCOBY, for symbiotic culture of bacteria and yeast). “I’m always using different flavors,” she says—in this case, ginger, which Khawaja employed as an effervescent topper for his cocktail, the Tomfoolery. The drink’s based on Scofflaw’s proprietary Old Tom Gin, produced by North Shore Distillery (it’s available for retail at the bar).
