Red Rose Tea is brewing up three of its best-selling black tea blends in a new single-serve-cup format. Red Rose Original, Red Rose Naturally Decaffeinated and Red Rose English Breakfast now are available in single-serve cups for consumers who have shifted to brewing tea in single-serve machines, the company says. Like the teas in the bagged format, the single-cup teas are 100 percent natural and do not contain calories, gluten or sugars, the company says. Red Rose Tea single-cup teas are available at select retailers nationwide as well as online for approximately $6.99 for a 12-count box.
