A single 15 fl oz can of Starbucks Doubleshot Energy Vanilla delivers 135 mg of caffeine, roughly 34% of the FDAs 400 mg daily cap. Thats about 9 mg per fluid ounce. The smaller 6.5 oz Doubleshot Espresso cans pack 120 mg, way more concentrated at 18.5 mg per ounce.

Two Energy cans hit 270 mg, and three puts you just over the limit at 405 mg.

How much caffeine is in Starbucks Doubleshot Energy?

The info below does not come from some calculator or converter tool on this page. They are based on actual user reviews, forum chats and coffee community experiences, that one finds everywhere on the net.

Starbucks Doubleshot Energy is a ready to drink coffee beverage in cans. In short it mixes coffee with Energy drink. The formula combines Starbucks coffee with ingredients that boost Energy, like guarana, ginseng and vitamins B. That mix of coffee and Energy extras helps it stand out from simple smooth coffee.

One can choose between some different tastes. The mocha version presents natural mocha flavor in smooth coffee drink. Vanilla forms another favorite option, that combines rich espresso with Vanilla fragrance.

There is also a white chocolate version. The Vanilla and white chocolate flavors apparently are favorites among fans.

The cans come in various sizes. Bigger cans have 15 fluid ounces, and there is also a smaller version of 11 ounces. One usually will sell teh 15 ounce cans in packages of 12, while the 11 ounce ones appear in sets of 4.

The packaging can change depending on the store, where one buys.

Here is where things get interesting. The Energy form of Doubleshot differs from the Doubleshot Espresso cans. It stores coffee together with guarana, ginseng and vitamins B. In a 15 ounce can, it carries 1800 mg of taurine, 450 mg of L-carnitine, 180 mg of inositol, 325 mg of ginseng and 90 mg of guarana.

The amount of Caffeine matches that which original Monster and Rockstar offer. The mocha version has around 135 mg of Caffeine per 15 ounce can, while the white chocolate has about 145 mg. The Vanilla in 15 ounces apparently stores 225 mg of Caffeine.

From a calorie viewpoint, the drink reaches 210 calories with 2.5 grams of fat and fairly high sodium content. The sugar amounts stay a constant challenge. It also provides 10 grams of protein four 200 calories, which genuinely stands well compared to almost every other Energy drink, even beating the Monster coffees.

The drinks are kosher certified nationally. One finds them in stores like Target and Kroger, and they are available on Amazon. Some stores offer delivery in same day or curbside pickup.

For folks in rural areas, regularly getting them can be hard, so buying in big amounts online is a common way.

One weird fact to know: newer Doubleshot cans apparently do not have Caffeine. The old recipe had strong impact, but the new version still includes guarana, ginseng and vitamins B without any note about Caffeine. It caused a bit of confusion, becausecalling something “Doubleshot Energy” without Caffeine sounds strange.
