Tag: Blonde vs regular espresso

According to Starbucks' official information and data from multiple reliable sources, one single shot of blonde espresso at Starbucks contains 85mg of caffeine. This is slightly more potent than their standard Signature Espresso, which typically contains 75mg per shot, a fact that often surprises many customers.

While most people assume darker roasts are stronger, a 2021 study by Shady Awwad found light roast coffee contains slightly more caffeine per ounce than dark roast. This means blonde lattes, made with light-roasted espresso, can have a slight edge in caffeine content over their darker counterparts.
