Starbucks Iced Coffee- Does It Have Caffeine, Price For All Cup Sizes

Starbucks Iced Coffee

Starbucks iced coffee is a popular drink amongst many people.

However, many different cup sizes make it difficult to know how much caffeine they are getting. 

This article will explain the difference between each size of iced coffee and what each drink contains in terms of caffeine content.

Let’s get started!

Does Starbucks iced coffee have caffeine?

Does Starbucks iced coffee have more caffeine?

The short answer is yes; iced coffee contains caffeine. However, Starbucks has many different size options, so it can be unclear to know exactly how much caffeine is in the drink. 

So how much caffeine is there in Starbucks iced coffee?

Well, it’s all dependent on the size of the cup that you order. The average size of iced coffee is 12 fl oz. Therefore, iced coffee contains anywhere between 50-150 mg of caffeine per 12 oz serving.

Different Sizes:

Starbucks offers four cup sizes for their iced coffees (24oz, 16oz, Trenta, and Tall). While this may make it easy for some to decide what size they want to order because they know how many scoops of ice or ice cubes they want in their drink. 

But for some it can be unclear to figure out the exact amount of caffeine that comes with each size.

  • Tall: This size is 12 oz or 355 ml.
  • Grande: This size is 16 oz or 473 ml.
  • Venti: This size is 24 oz or 710 ml.
  • Trenta: This size is 30oz or 894ml.

How much caffeine does the tall cup size contain?

The tall size contains 70-120 mg of caffeine. The average Tall espresso has about 38-46 mg of caffeine.

How much caffeine does the grande cup size contain?

The grande contains 165 mg of caffeine. The average Grande espresso has about 57-70 mg of caffeine.

How much caffeine does the venti cup size contain?

The venti size will contain 180-235 mg of caffeine. The average Venti espresso has about 71-85 mg of caffeine.

How much caffeine does the Trenta cup size contain?

Trenta contains 285 mg of caffeine. The average Trenta espresso has about 85-105 mg of caffeine.

Is 285 mg of caffeine a lot?

As per studies, 100 to 200 mg of caffeine (about 1 to 2 cups of regular coffee) is sufficient. Caffeine consumption of 250 to 700 mg per day may cause nausea, headaches, sleep difficulties, or increased anxiety. More than 1,000 mg may cause heart palpitations.

As you can see, the smaller sizes of iced coffee (Trenta and Venti) usually contain more caffeine than the larger cups (Grande and Tall). So if you want some caffeine buzz to start your day, I recommend going with the grande or tall drink sizes.

Are the caffeine content amounts in each drink accurate?

How can I measure the caffeine content in drinks?

These amounts are a rough estimate, and the actual content in each drink will vary. Many factors can influence caffeine content in a coffee drink, including bean selection, roast, grind size and method, brew ratio, coffee to water ratio, initial temperature, and steeping time.


Iced coffee contains a little bit of caffeine, but it’s nothing a cup of black coffee won’t cure. A few cups of iced coffee a day is wonderful and beneficial for your health!
