Amount of Caffeine in Starbucks Green Tea Drinks
If you’re curious about your daily caffeine intake or proactively seeking the strongest drinks from a Starbucks green tea beverage, this is the best report for you to learn more.
Review this reference guide for a comprehensive overview of the amount of caffeine in each beverage.
Starbucks Caffeine Information Guide
This quick reference guide to the amounts of caffeine in green tea beverages from Starbucks coffee shops is based on standard brewing or steeping methods without substitutions or additional flavors.
Beverages made without any add-ins, such as syrup flavoring, cream, or foam, contain a higher amount of caffeine per serving. The simple reason is because there is more room in the cup for the tea. The tea, not the cream, contains the caffeine.
As a result, a simple tea drink made with tea bags and hot water will have more caffeine than if the drink is mixed with coconut milk, a protein boost, or other add-in.
Starbucks Green Tea Latte
A standard Grande Matcha Latte from Starbucks has 65 mg of caffeine. For comparison, a typical home-brewed coffee has 85 mg of caffeine.
Check the table below for the amounts of caffeine in hot green tea lattes, matcha teas, and iced tea latte beverages.

What’s in an Iced Matcha Latte?
Starbucks iced matcha latte is a handcrafted drink made with unsweetened matcha, milk, and sweet syrup. The drink is served over ice.
A standard matcha latte is made with 2% milk. However, you may select other dairy or non-dairy options, such as oat milk, almond milk, or soy milk. Select locations may offer cashew milk.
You can also add a protein energy boost to customize your delicious drink.
As you continue to learn about the nutritional values of your favorite beverage, compare the caffeine content in Starbucks Matcha Latte options to how much caffeine is in Starbucks Iced Coffee drinks.

A cup of matcha with added milk or syrup has less caffeine per serving compared to a straight hot water and matcha mixture.

Most Starbucks beverages are available in three sizes: Tall, Grande, Venti. Select iced drinks are also available in the largest option, known as a Trenta.
Amount of Caffeine Decreases With Add-Ins
Ordering milk or another add-in with Starbucks teas generally results in a lower amount of caffeine per serving. Milk takes up space in the glass or cup, which leaves less room for the brewed tea and thus less caffeine.
The same holds true when adding sweeteners, syrups, or cold foam. Tea drinkers who enjoy a sweeter iced matcha green tea latte can choose from various flavor options, such as vanilla or maple syrup, among others.
Starbucks Iced Green Teas
Other Iced options include iced green tea as well as a blend of green tea and lemonade. Here are the amounts of caffeine in iced tea beverages, including the popular Iced Peach Green Tea made with spearmint, lemon verbena, and lemongrass flavors.
