Caffeine Conscious

  • Starbucks Caffè Mocha Grande 175mg of caffeine
  • Starbucks Caffè Latte Grande 150mg of caffeine

How Many Shots?

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

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


Coca-Cola 34mg Caffeine

Coca Cola could be considered the earliest “energy drink” – although not marketed as such – it was one of the first carbonated drinks to contain caffeine.

The drink was first made in 1886 – where it supposedly had a very small level of cocaine in it – due to the extract of coca leaf being an ingredient. However, given that the formula has always remained secret – this may simply be an embellishment. 

The Diet Coke range actually contains about 32% more caffeine than the standard coke formula.


Beverage Caffeine Per 8 oz Cup
White Tea 30-55 mg
Green Tea 35-70 mg
Oolong Tea 50-75 mg
Black Tea 60-90 mg

True tea is made from the leaves of an Asian evergreen known as Camellia sinensis. White tea, green tea, oolong tea, and black tea all come from this plant, and all contain caffeine. Our herb teas are made from other, unrelated plants and do not have any caffeine. One exception is Yerba Maté, an herb tea that does contain caffeine.

Researchers believe that in plants, caffeine works as a natural defense system to deter insects and other herbivores with the compound’s bitter taste and stimulating qualities. And, not so surprisingly, it’s the vulnerable, growing buds and young leaves of tea plants that manufacture the highest amounts of caffeine.

Many factors influence how much caffeine is present in plucked tea leaves. These include the growing region, plant varietal, plant age, leaf age, length of the growing season, field conditions, soil nutrients, rainfall, and stress by pests. Final caffeine content may be further affected during production of the leaves into the finished “style” (white, green, etc.).

How the tea is actually prepared plays an important role in how much caffeine makes it into your cup. Everything, from the amount of tea used to water temperature and brewing time to whether the leaves are steeped loose, in a tea bag, or strainer, becomes a factor. In general, though, more tea, hotter water, and longer steeping all contribute to more caffeine per cup


Brewed Coffee 163mg Caffeine

Drip Coffee is the Most Popular

Drip coffee is perhaps the most popular form of brewed coffee, at least in the USA. This is the method used by Starbucks, Dunkin Donuts, McCafe as well as countless other restaurants.

Even K-cups are a type of drip brewed coffee.


Red Bull 80mg Caffeine

Red Bull Energy Drink was created in Austria more than 28 years ago.

It is one of the very first energy drinks and is now distributed in more than 169 countries worldwide.

It is the #1 selling energy drink with 60 billion cans sold to date.

The incredibly popular energy drink has been a catalyst for dozens of imitations and has built a very strong brand – although the drink formulation has remained relatively unchanged.
