Ladies and gentlemen, get ready for the most caffeine-filled debate of your life: Which coffee has the most caffeine. For some of us, caffeine can be a major motivator or even an addiction.

But what if you need to stay alert and energized without relying too heavily on more than one cup of joe? What factors go into deciding which is best for you? To find out we took a deep look at three popular brands: Starbucks®, Dunkin Donuts®, and Peet’s Coffee & Tea®.

We’ll compare them in terms of flavor, cost per serving (or “caffeine punch”), supermarket availability (i.e., how easy it is to buy), customer satisfaction ratings across social media (“ooh’s” and “ahh’s”), and the average caffeine content per serving.

1. The caffeine content of coffee:

When the topic is coffee and caffeine, we need to start with how much caffeine can be found in a typical serving. Even though it may seem like every cup of coffee has the same amount, this isn’t true.

You see, each cup of coffee varies – and can vary greatly – depending on where you get your java. The truth is that the way coffee is roasted, ground and brewed varies greatly around the world. For example, some of Starbucks’® iced espresso drinks contain nearly three times the amount of caffeine than a similar size iced tea beverage. 

Take-away: The amount of caffeine in one cup can vary depending on where you get it. Generally speaking, the darker the roast, the more caffeine.

2. How to measure your caffeine intake:

Now that you know the caffeine content in a cup of coffee, it’s time to talk about how much caffeine is actually in your system. The answer to this question depends on multiple factors including:

a) What type of coffee drink do you have?

b) How big was your serving?

c) How much caffeine does your particular body process?

There are so many different ways to drink coffee. For instance, some people opt for an iced espresso drink with extra shots while others prefer a simple cup of drip coffee.

Since there is no standard serving size, the amount of caffeine in your system will ultimately come down to how big your cup or blended beverage was.  Even if you order the same size at Starbucks®, Dunkin’ Donuts®, and Peet’s Coffee & Tea®, your serving may be larger or smaller depending on which location you visit. 

Take-away: The amount of caffeine in a cup of coffee varies greatly depending on where it is brewed and what type of drink you’re having.

3. How much caffeine is in your coffee?

We’ve talked about how much caffeine is in a cup of coffee, but we still need to answer the last question: How much caffeine will you actually ingest? You see, when it comes to determining your individual caffeine intake, there are two more important factors:

a) Your choice of creamer

The amount of creamer you add will determine how much caffeine is in your coffee. Since some people prefer their coffee with heavy cream or half and half, they end up ingesting less caffeine than someone who pours in skim milk.

This is because the more fat there is in your drink, the slower it will be to digest. For example, half and half is made up of at least 18% milk fat, and whole milk is about 3%.

This means that it takes your system longer to process these types of dairy than skim or soy milk alternatives. The bottom line: the more exogenous insulin you release into your body, the less caffeine you will absorb into your system.

b) The type and strength of your brew.

The type of coffee you choose also goes hand-in-hand with how much caffeine is in your cup. For example, most people know that a “grande” iced latte from Starbucks® has more caffeine than a brewed drip coffee.

In fact, there are some drinks – like the black forest mocha – that are packed with caffeine thanks to extra shots of espresso. If you’re trying to limit your daily caffeine intake, it may be best to choose a simple cup of black coffee instead of one that comes loaded with sugar and chocolate syrup.

There are many factors that will determine how much caffeine is in your drink. Be sure to check out our caffeine database so you can see how much caffeine is in your favorite drink!

3. What are the differences between Starbucks®, Dunkin Donuts®, and Peet’s Coffee & Tea®:

Iced espresso drinks from Starbucks® and Dunkin Donuts® generally contain more caffeine than a similar size iced tea because of the way they’re brewed. The truth is that all three places make their drinks differently:

a) Dunkin’ Donuts®:

The coffee Dunkin Donuts

Dunkin Donuts uses a coffee extract to make its iced coffee. The extract is made by mixing together coffee, water and sugar and then adding the mixture to a large container of cold milk.

This means that all of their drinks – not just their iced coffee – will taste sweeter than what you get from Starbucks® or Peet’s Coffee & Tea®.

b) Starbucks®:

The coffee Starbucks

Starbucks® now has a cold brew coffee. Cold Brew is brewed differently from iced coffee, as it is made with room temperature water instead of hot water. That being said, most people overlook how much power goes into making an iced espresso beverage.

According to Starbucks®, it takes 20 ounces of hot espresso and another 20 ounces of steamed milk to make a 16 ounce iced latte. That’s almost double the caffeine of a regular hot brewed espresso!

c) Peet’s Coffee & Tea®:

The coffee Peet's Coffee & Tea

Peet’s is focused on one thing – making coffee. They have spent many years perfecting their roasting and blending techniques to ensure that every cup you get tastes as fresh as the one you get in their stores.

Because of this, they brew their iced beverages with room temperature water so that it doesn’t burn or destroy the flavor of the coffee. That being said, because there’s no hot water involved when it comes to making Peet’s drinks, you can expect a far weaker beverage than what you get from Starbucks®.

If you’re looking for a simple cup of coffee or tea, consider going with Peet’s Coffee & Tea®. However, if you want something strong and sweet to wake you up in the morning, try Dunkin Donuts® iced coffee.

Another great thing about Dunkin Donuts is their low price. If you’re looking to save some money, go with Dunkin Donuts®!

FAQs:

1. How many fluid ounces are in a serving?

A regular cup of brewed coffee is generally between 8 and 12 ounces. Our database assumes the standard 10 ounce cup is used for calculations. However, if you have questions about your specific brew, please contact us for more information.

2. Why do I need to know how many ounces are in a cup of coffee?

It’s important to know how much fluid is in your cup because that will affect the final caffeine calculation. For example, if you have an 8 ounce serving, then you’ll need to divide all the amounts by 8 instead of 10 when calculating caffeine concentration per ounce.

3. Why do some drinks contain more caffeine than others?

Caffeine is an organic compound that naturally occurs in certain plants, including coffee beans. As a result, it’s difficult to make any general statements about which drinks are “strongest.

” Within each brand, some drinks can have more caffeine than others depending on how they are made. For example, Starbucks® makes both standard and non-caffeinated versions of some drinks. As a result, the non-caffeinated version may be less strong than what you get from Dunkin Donuts® or Peet’s Coffee & Tea®.

4. If I need more caffeine, should I drink two cups of coffee?

When it comes to drinking coffee, the two-cup method is a good idea for many people. However, you should consider other factors such as how much caffeine you currently get from your coffee and whether or not that amount suits your needs.

Conclusion:

If you’re looking for a simple cup of coffee or tea, consider going with Peet’s Coffee & Tea®. However, if you want something strong and sweet to wake you up in the morning, try Dunkin Donuts® iced coffee. Another great thing about Dunkin Donuts is their low price. If you’re looking to save some money, go with Dunkin Donuts®!
