Frizzantea Sparkling White is the still-white-style entry in M&S's Frizzantea sub-range, a group of sparkling tea-based non-alcoholic drinks that also includes Brut and Rosé expressions. The base is Darjeeling tea sourced from the foothills of the Himalayas, cold-brewed for up to 24 hours, a process the brand uses to develop a more delicate and complex character than conventional hot-brewed tea allows. The resulting profile carries notes of elderflower and jasmine, and the drink is positioned as an alcohol-free alternative to sparkling wine suited to food occasions.
