Strawberries and citrus are macerated with sugar, orange liqueur, and vodka or tequila, then finished with red wine and seltzer for an extra-spirited sangria.
Toss fresh fruits with sugar, vodka, and Cointreau. Cover; refrigerate, tossing occasionally, at least 4 hours and up to 1 day. Fill a glass halfway with frozen fruit, if desired. Add macerated fruits, and top with wine and a splash of seltzer, if desired.
