Dunkin’s Refreshers are a new addition to their menu. They were introduced in the summer of 2020, almost a decade after their competitor Starbucks.

The refreshers were announced as a bright, fresh, and exciting product to lift customers’ moods during the long pandemic months. They are now available at most Dunkin’ locations across the country.

The base of a Dunkin’ Refresher consists of iced green tea, fruit concentrate, and B vitamin. Green tea is the source of caffeine in the refreshers. 

The fruit concentrate is derived from water, sugar, natural flavors, and green tea extract. The type of fruit concentrate included in the refresher depends on the flavor choice.
