What type of tea is served as iced tea at Dunkin Donuts?

Iced tea at Dunkin Donuts is made using regular black tea. This choice is correct because black tea has a robust flavor that stands up well to being served cold and often has a refreshing quality when iced. The brewing process typically involves steeping black tea leaves in hot water, which then allows the tea to develop its rich taste. When served over ice, black tea can be enhanced with sweeteners or flavors, making it a popular choice for those looking for a refreshing beverage.

Other varieties like herbal tea or fruit-infused tea generally have distinct flavor profiles that may not translate as well when served over ice. Regular green tea, while popular, is not the base for Dunkin's iced tea offering, as it tends to have a lighter, more delicate flavor, which might not appeal to the same taste preferences that black tea does. Thus, the use of regular black tea for iced tea aligns with Dunkin Donuts' approach of providing a strong, familiar flavor that appeals to many customers.
