Dunkin’ Donuts Origins

In 1948, a Quincy, Massachusetts restaurant named Open Kettle offered customers donuts and coffee for nickels and dimes. In 1950, however, the company decided it was time to rebrand. Its new name? Dunkin’ Donuts. The goal? Sell the best coffee and donuts at a decent price for people to enjoy. By 1955, it was a franchise with 100 shops.

Today, Dunkin’ Donuts has an extended menu of food items, several coffee beverages, and of course, donuts. Anyone who wants a quick breakfast and a coffee before starting a busy day can swing by their nearest location to find something that will hit the spot.

Hot, Fresh Coffee

One of the signatures of Dunkin’ Donuts is their hot, freshly brewed coffee. Not only does it taste great on a busy morning, but it goes well with a tasty donut when possible. While regular coffee is of course their signature hot beverage, that does not mean they haven’t added flavors and other options to warm you up daily. Let’s take a look at the caffeine content in some of Dunkin’ Donuts’ most popular hot coffee beverages.
