Dunkin’ is bringing some exciting espresso energy into the new year. On December 31st, it announced the limited time “Sabrina’s Brown Sugar Shakin’ Espresso” beverage in partnership with pop singer Sabrina Carpenter.

If you don’t know who that is, her hit song “Espresso” single-handedly helped Americans pronounce espresso correctly. Hint: it’s not ex-presso!

Because Starbucks popularized the iced shaken espresso, I had to compare the OG (Starbucks’ Iced Brown Sugar Oatmilk Shaken Espresso) to this Dunkin’ offering.

Starting with beverage build: While the beverage may seem simple – espresso, brown sugar, and oatmilk – there are differences in how each is made.

First, the espresso itself: Dunkin’ uses what it calls “bold espresso,” which I assume is a standard dark roast. Starbucks uses blonde espresso, a lighter roast with a higher caffeine content. Second, the brown sugar: Dunkin’ calls it “brown sugar notes,” whereas Starbucks specifies “brown sugar and cinnamon together.” Lastly, I will quickly note that both list “oatmilk,” but spoiler alert: this ingredient makes a huge difference in taste.

Now, onto the actual beverage experience and taste test: The first thing I noticed was size (insert one of Sabrina Carpenter’s dirty jokes here, as she often makes them). I usually don’t order Dunkin’ and Starbucks simultaneously, but the value comparison was striking when compared side-by-side. A small iced at Dunkin’ is 16 ounces, whereas a small at Starbucks is 12 ounces. The latter is 15% more expensive and 4oz less! +1 to Dunkin’.

However, I’d rather have less of a good thing than more of a “just okay” thing. Flavor-wise, Starbucks’ version just tasted better. It had more depth – the brown sugar tasted less corn syrup-like and more deep and developed with the cinnamon as the final note.

Dunkin’s version, on the other hand, started strong. It was more espresso-forward, but I couldn’t get over the aftertaste. It wasn’t overpowering but faintly artificial and what I can only describe as “eggy” or yolk-like tasting, which I attributed to the oatmilk. Dunkin’ typically uses Planet Oat oatmilk, while Starbucks uses Oatly.

Ultimately, Dunkin’s drink reminded me more of a “regular” Starbucks Iced Shaken Espresso—not quite delivering on the promise of a Brown Sugar Oatmilk Espresso.

Sabrina made me do it, but I’m sticking to Starbucks for this shaken espresso rendition!
