Once banned in New York for nearly a century, black currants are back in cultivation, celebrated for their deep, tart flavor and antioxidant power. Thoroughwort, a wild native herb with a subtle, bitter edge, has long grown across the state’s meadows and been used in traditional remedies. Now combined with crisp, subtly sweet birch sap, this seltzer balances sharp fruit and earthy complexity with a clean, refreshing finish that’s uniquely rooted in New York’s wild past.
