How Much Caffeine in a Starbucks Doubleshot?

Starbucks offers three standard varieties of doubleshot drinks: doubleshots on ice, canned doubleshots, and hot espresso doubleshots. Theoretically, each of these beverages contains two espresso shots, but in practice, the amount of caffeine in each one varies significantly.

But hold on! More complexity exists than that: Doubleshot Energy and Doubleshot Espresso are two of the canned drinks that Starbucks sells. Guarana, ginseng, and B vitamins are also present in the energy version, including brewed coffee. In the espresso variation, it is espresso combined with milk, sugar, and cream.

Although the espresso version is much more intense, they both contain roughly the same amount of caffeine. While a 6.5-fluid ounce (192.22 milliliters) can of Doubleshot espresso has 0.0042 ounces (120 milligrams) of caffeine, a 15-fluid ounce (443.60 milliliters) can of Starbucks Doubleshot energy has 0.0047 ounces (135 milligrams) of caffeine.

Starbucks doubleshot energy, on the other hand, contains 0.00031 ounces (9 milligrams) of caffeine per fluid ounce (29.57 milliliters). That is 0.0010 ounces (30.43 milligrams) per 3.38 fluid ounces (100 milliliters).
