This robust herbal tea combines the distinctive sweet-tart flavor and enticing aroma of juicy raspberries with two kinds of hibiscus: fruity Thai hibiscus and its tart and tangy Chinese counterpart. Soothing and satisfying when served warm, Raspberry Zinger perfectly captures the taste of summer’s day when served over ice.â€
