Being two of the most popular teas around the world, it’s only right to compare these two especially with the focus on caffeine. Many have been asking what’s the caffeine difference between black tea and green tea? Well we’re here to answer your questions!
Before we begin diving into the details of the caffeine content between green tea and black tea, we’ll have to establish some standards here. In this article alone we’ll strictly reference only loose leaf black tea and loose leaf green tea. We can touch upon the caffeine content within black tea bags and green tea bags but we believe it’s more important to focus on loose leaf tea.
Plus, who doesn’t like loose leaf teas anyways? They’re higher quality leaves, more flavorful and ultimately has more benefits than tea bags! Read more about the difference between tea bags and loose leaf tea here if you’re interested.
Okay let’s begin!
How Much Caffeine is in Black Tea?
Loose leaf black tea (one of our favorite teas actually) typically has about 40 to 130 mg of caffeine in 1 cup. Now you might be thinking that the caffeine content of anything more than 100 mg is a lot. But let’s break this down for you and put it into perspective.
How does this compare to something that has even more caffeine, like coffee for example. Typically in any cup of coffee (like instant coffee or something from your neighborhood Starbucks) you’re looking to consume about anywhere between 150 and 400 mg of caffeine. Yes, there’s cups of coffee that will give you that boost of 400 mg of caffeine, now that’s a lot!
Has anyone tried something like this? If you’re interested, there’s actually a company by the name of Death Wish Coffee that will give you upwards of 700 mg of caffeine, isn’t that just insane? Who’s willing to try that, let us know! If you’re not someone who likes 700 mg of caffeine running through their system you can definitely try some of these more mellow black teas here: Davidsons Tea or Vahdam (this one is our favorite this month).
How Much Caffeine is in Green Tea?
Loose leaf green tea (another one of our favorites) generally will have a lower amount of caffeine than your stronger teas like black tea. And definitely a lot less caffeine than your “world’s strongest cup of coffee.”
In any one cup of green tea, you’re looking to have about 15 to 70 mg of caffeine. Now that’s a bit more modest and relaxing right? With 1 cup of green tea every morning you’ll feel relaxed but full of focus and energy. Usually green tea releases caffeine and absorbs into your body more slowly than your typical energy drinks and coffee. This is key to avoiding the caffeine crash that you might feel after drinking a 5-hour energy or another energy beverage.
What Determines the Caffeine Levels in Tea?
Many of the famous and popular teas you drink or your friend consumes is made from the Camellia sinensis plant. Just to give you an example, this plant is used to produce your green teas, black teas, oolong teas, herbal teas and more. Let’s just say this plant is the jack of all teas.
Type of Tea Consumed
All teas have some amount of caffeine whether it’s 10 mg or upwards of 100 mg. The amount differs based on what tea you’re interested in. For example we mentioned green tea has a lower caffeine amount than black tea. This is the same with any other tea leaves. Here’s a quick breakdown of the most popular teas and their caffeine levels.
- Green Tea – 15-70 mg
- Black Tea – 40-130 mg
- Oolong Tea – 20-40 mg
- Jasmine Tea – 20-45 mg
- White Tea – 5-30 mg
- Earl Grey Tea – 25-60 mg

Does Steeping Tea Longer Release More Caffeine?
Yes, if you think about it, the darker the tea (like black tea) will have more caffeine content. Why is this though? Usually, the darker the tea you’re consuming the more time it takes to steep in order to bring out its full flavor profile.
Since it’s optimal to steep these types of teas longer, you’ll find that these same teas will also have more caffeine. So, steeping tea longer does release more caffeine over time.
Different Tea Blends
Sometimes tea is blended with other types of loose leaf teas too, which change the level of caffeine significantly. For example a very popular tea blend in British culture with all sorts of black tea is the English Breakfast blend. This black tea blend consists of different types of black tea from Assam, Kenya and Ceylon.
Obviously these locations are far from each other around the world so it’s safe to assume that they’re processed differently too. With their different processes, caffeine levels are also different.
