The Complete Guide to Starbucks Caffeine

By Caffeine Informer Staff

Starbucks Coffee

We have compiled this chart using data from Starbucks in-store leaflets, from their website, and data from independent laboratory tests.

Caffeine in coffee can vary (due to coffee origin and blend used) and may be more or less than the amounts shown. Also, some locations may not make their drinks according to Starbucks’ exact guidelines.

Please visit our complete caffeine database for all other beverages. See detailed breakdowns of caffeine in Dunkin’ DonutsCaribou Coffee, or Tim Hortons.

Tazo Tea Caffeine: Retail vs Outlet

The caffeine amounts given above for Tazo Brewed Tea are very high (these are from Starbucks).

Independent Lab tests have shown that Tazo Earl Grey has about 40-59mg caffeine (when brewed in 6oz water). Tazo China Green Tips has 23-41mg caffeine. Apparently Starbucks cafes use a different size teabag in-store compared to the retail packets (but we have been unable to confirm).

See more about caffeine in black tea here.

Caffeine in Espresso-based Drinks is Governed by the Number of Shots

The caffeine amounts of the espresso based drinks show that a Tall Latte (and Cappucino) has just a single shot of coffee. For a 12 oz cup size – this is quit weak and has considerably less caffeine than a brewed coffee of the same size.

Any conscientious coffee vendor will, by default, serve at least a double-shot in drinks over 8 ounces. Some even provide double-shots (by default) in regular takeaway cups. This is because many takeaway cups tend to have more volume than their china or crockery counterparts.

How Accurate Are These Amounts?

Starbucks make it clear that “Caffeine information is approximate and is based on limited analytical data.” and also that “Values can vary greatly based on the variety of the coffee and the brewing equipment used.”

This is completely true; caffeine amounts in coffee-based drinks can vary wildly.

A recent laboratory test sampled a series of Starbucks Breakfast Blend brewed coffees. The caffeine dose varied from 299.5mg right up to a massive 564.4mg per 16oz cup! What’s astonishing is that the 6 samples were obtained from the same outlet on 6 consecutive days.

Beware: Decaffeinated Drinks Still Contain Caffeine

Decaffeinated isn’t the same thing as caffeine-free.

An independent lab test of Starbucks coffee showed the following:

  • Decaf Brewed Coffee – 12.0–13.4 mg/16-oz serving (Starbucks have decided to list considerably more caffeine than this – 25mg per 16 oz).
  • Decaf Espresso – 3.0–15.8 mg/shot.

    I always bring up how much caffeine is in starbucks when people say something about my energy drink consumption.

  • spazman

    @ Scum1

    I know how you feel. Someone I know had the nerve to tell me energy drinks are bad for me when she had an exceptionaly large cup of coffee in her hands.

  • KarlieMildraed

    Didn’t I mention this earlier in another thread. Just a wonderment for me. hummm….

  • Adam

    I hate that. My stepmom drinks a crapload of coffee, but she tells me that “those” drinks are going to cause all sorts of health problems.

  • wowsers

    I recently gave up coffee/caffeine (2 weeks) and I’m buckling. This site actually showed me the Rockstar drinks I was drinking had less caffeine than my usual starbucks coffee. Damn!

    the sweet yet bitter embers of ikea coffee granules (their coffee is amazing) are singing to me from the pantry. Do I make a cup or go without?

    I actually gave caffiene up because my threshold was getting too high after a road trip. Three Rockstars in a day to stay awake on the road is excessive in my opinion, but so is being dead from driving tired.

  • Keith

    Mmmm….coffee. What’s the big deal about it being bad for you? Go to any small town coffee shop, and you’ll see 20 old folks sitting around drinking coffee and swapping gossip. People have been drinking coffee for millenia. My friend from Croatia laughs at the big deal we Americans make about coffee. Over there, they drink far more than we do in the US….turkish demi-tasse all during the day. Wahoo!! I think I’ll move to Europe.

  • Dan and Amelia

    Just an observation, you mention a Grande Latte has 12 oz. and one shot-that is incorrect. A Grande Latte has 16 oz and 2 shots, and the Tall size has 12 oz and one shot. I understand the point, but only because we are employees and were able to guess what you meant. If your going to make an argument you may as well make it accurate. BTW, who are “Contientious Coffee Vendors?” Thanks for the condecending bias, too.

  • http://www.johnstamos.net UncleJesse’s mullet

    Thanks 4 posting this list! Very interesting & informative. I think that coffee-drinking people & energy-drink drinking people should all unite…One nation under caffeine. :-) Starbucks Coffee 4ever! -Still looking 4 John Stamos…

    caffeine makes u poop.

  • Lainebug

    I work for Starbucks and can answer a couple of these questions, a Tazo Chai Tea latte is a spiced black tea concentrate and has a specific recepie therefore the caffeine content should always be about the same where actual leaf tea can vary depending on the plant from which it came, this also goes for different coffee blends; the lighter the roast the more caffeine in the coffee because caffeine is roasted out of coffee beans which is why ther is a little caffeine left in decaf coffee. As for our latte’s caffeine content, anything over 12oz will contain at least 2 shots of espresso, on the 12oz and 8oz drinks contain one shot of espresso. Hope this helps anyone concerned about their caffeine intake!

  • caffeine-free

    I just wanted to say that I rely on caffeine information. I have cardiac rhythm problems, and recently had a procedure done. Caffeine makes my racing heart and arrhythmias worse. A lot of people do well with a bit of caffeine daily, but others really have health problems which are exacerbated by caffeine. I’ve had the arrhythmias for years, particularly after age 30 and I quit caffeine then (or so I thought but then discovered that there are small amounts in all kinds of things!), and the racing for about a year – in my mid 40′s. Occasionally, I come across something that surprises me like the Propel water, etc., containing caffeine, or that the green teas do have some caffeine. Guess I’ll stick with water!

    it’s the shit inside the energy drinks that are bad for you, not all the caffeine. and those energy drinks have WAY more caffeine in them than coffees…you’re dumb read a newspaper.

  • idiots.

    p.s. coffee reduces your risk at getting skin cancer.

  • Jan

    The argument shouldn’t be that simply some drinks are bad and others are good. Energy drinks contain a whole list of ingredients – some of which are ok and some of which have been proven to cause health problems (artificial sweeteners, food coloring, preservatives, and other chemically created flavours). Be an informed consumer and look at the list of ingredients. As for coffee, it has some benefits, but causes other harms. It may reduce risks of certain cancers and it may be used medicinally for headaches, high blood pressure, or getting more done at work, but it is also also a diuretic. The caffeine speeds up digestion forcing your body to rid itself of waster sooner. The result is that less nutrients from your other foods are digested in the intestines. Less nutrients = health problems. Which is why green tea is championed for its health. Less caffeine, more medicinal properties, and antioxidents.

    As far as the Tazo tea, in the Tea lattes, we use a powder to flavor the beverage (it is a derivative of the tea) but it is a lot more refined and predictable than is straight tea leaves. It is also manufactured by starbucks corporate directly. The actual tea in the store is straight tea leaves, and caffeine content varies based on where the crop comes from. It is impossible to generate a baseline level for the straight tea leaves.
    Just thought you might like to know.

  • Tim

    Not sure how accurate this is, but one thing that I looked for right away was the caffeine content difference between a grande and venti Americano. I’ve asked a few times what the difference is and they’ve told me they have the same amount of shots of espresso, the hot water is the only difference.

  • PJ

    Actually I believe the Venti Americano is 4 shots

  • ST

    Venti Americano has 4 shots – Had two today both with an extra shot – 5 shots each
