Earl Grey tea is one of the most popular flavored teas in the world, known for its distinctive citrusy aroma, thanks to the addition of bergamot oil. But for those who enjoy a daily cup (or two), a common question arises: Is Earl Grey tea high in caffeine?
Caffeine content plays a crucial role in how tea affects energy levels, focus, and even sleep patterns. Some tea drinkers seek a morning boost similar to coffee, while others prefer a more soothing experience. So, how does Earl Grey compare to other teas and coffee? And does its caffeine level vary depending on how it’s brewed?
In this article, we’ll dive deep into the caffeine content of Earl Grey, compare it to other beverages, explore its effects on the body, and help you choose the right type based on your caffeine needs.

Understanding Caffeine in Earl Grey Tea
How is Earl Grey Tea Made?
The base of Earl Grey tea determines its caffeine content. Most versions are made with black tea leaves, which are oxidized longer than green or white tea, resulting in a richer flavor and a naturally higher caffeine level.
The tea-making process involves:
- Harvesting the Tea Leaves – Tea leaves are picked from Camellia sinensis plants.
- Oxidation and Drying – The leaves are oxidized, darkening their color and enhancing their caffeine concentration.
- Infusing with Bergamot Oil – The dried tea leaves are blended with bergamot oil, which gives Earl Grey its signature aroma.
Because the oxidation level of black tea impacts its caffeine strength, different Earl Grey blends may vary in their stimulant effects.
Why Does Earl Grey Contain Caffeine?
Caffeine is naturally found in Camellia sinensis, the plant from which all traditional teas, black, green, oolong, and white, are derived. Earl Grey, being a black tea, contains a moderate-to-high amount of caffeine depending on:
- The variety of black tea used
- The steeping time (longer steeping releases more caffeine)
- The tea-to-water ratio (stronger brews have more caffeine)
While Earl Grey isn’t the most caffeinated tea out there, it still provides a noticeable energy boost, making it a great alternative to coffee for those looking for a less intense but still effective stimulant.
How Much Caffeine is in Earl Grey Tea?
Average Caffeine Content in a Cup of Earl Grey
One of the most common questions among tea drinkers is: Is Earl Grey tea high in caffeine? The answer depends on several factors, but generally, a standard 8-ounce (230ml) cup of Earl Grey contains between 40 to 90 milligrams of caffeine.
To put that into perspective:
- A typical black tea contains 40–70mg of caffeine per cup.
- A standard green tea has 30–50mg per cup.
- A cup of coffee can have anywhere from 80–150mg of caffeine.
This means that while Earl Grey is more caffeinated than green or white tea, it still falls short of the caffeine kick that coffee provides. However, brewing techniques can impact the final caffeine amount in your cup.
Comparison with Other Teas: Green, Black, and Herbal
Caffeine content varies across different types of tea. Here’s how Earl Grey tea stacks up against other common teas:
| Tea Type | Caffeine per 8 oz cup |
|---|---|
| White Tea | 15–30mg |
| Green Tea | 30–50mg |
| Oolong Tea | 40–70mg |
| Earl Grey (Black Tea) | 40–90mg |
| Matcha Tea | 60–90mg |
| Yerba Mate | 85–110mg |
| Coffee | 80–150mg |
While herbal teas like chamomile or rooibos have zero caffeine, Earl Grey falls into the moderate caffeine category, stronger than green tea but not as intense as coffee.
How Brewing Time Affects Caffeine Levels
Steeping time is a major factor in caffeine extraction. The longer you brew your tea, the more caffeine it releases.
- A 1-minute steep: ~20–30mg of caffeine
- A 3-minute steep: ~40–60mg
- A 5-minute steep: ~60–90mg
If you’re looking for a stronger caffeine boost, steep your Earl Grey tea for at least 5 minutes. However, steeping too long can make the tea taste bitter due to the extra tannins released.
Different Brands and Their Caffeine Content
Not all Earl Grey teas are created equal. Some brands offer high-caffeine blends, while others focus on a milder experience. Here’s a comparison of some popular brands:
- Twinings Earl Grey – ~50mg per cup
- Tazo Earl Grey – ~45–55mg per cup
- Stash Double Bergamot Earl Grey – ~50–70mg per cup
- Zest Tea High Caffeine Earl Grey – ~150mg per cup
If you’re looking for a bigger energy kick, brands like Zest Tea enhance their Earl Grey with additional tea extracts for a higher caffeine content than coffee.
Is Earl Grey Tea Considered High in Caffeine?
Comparing Earl Grey to Coffee and Other Beverages
When answering Is Earl Grey tea high in caffeine?, it’s crucial to compare it with other common drinks. While Earl Grey is stronger than green tea, it still contains about half the caffeine of coffee.
- Earl Grey (40–90mg per cup) vs. Coffee (80–150mg per cup)
- Earl Grey vs. Energy Drinks (100–300mg per can)
- Earl Grey vs. Soda (20–40mg per can)
For those who need a significant caffeine boost, coffee is the clear winner. However, for a milder energy lift without the jitters, Earl Grey is an excellent choice.
Factors That Influence Perceived Caffeine Strength
Even though Earl Grey contains moderate caffeine, some people feel it’s stronger or weaker than expected. Here’s why:
- Personal Caffeine Sensitivity – Some individuals metabolize caffeine quickly, while others feel its effects more strongly.
- Brew Strength & Steeping Time – A stronger brew can double the caffeine in a cup.
- Tea Leaf Variety – Assam-based Earl Grey tends to have higher caffeine than Darjeeling-based blends.
- Blended Ingredients – Some brands enhance Earl Grey with extra tea extracts, increasing caffeine levels.
For those with caffeine sensitivity, a lighter brew or a decaf version may be a better choice.
Decaffeinated Earl Grey: How Much Caffeine is Left?
Even decaffeinated Earl Grey isn’t completely caffeine-free. Most decaf teas undergo a process that removes about 97% of the caffeine, leaving behind 5–10mg per cup.
If you’re looking for an Earl Grey-style tea with zero caffeine, Rooibos Earl Grey is a great alternative since rooibos tea is naturally caffeine-free.
Effects of Caffeine in Earl Grey Tea on the Body
Does Earl Grey Tea Keep You Awake?
Many tea lovers wonder: Is Earl Grey tea high in caffeine enough to keep you awake like coffee? The answer depends on how your body reacts to caffeine.
Since a cup of Earl Grey contains 40–90mg of caffeine, it can provide a noticeable boost in alertness, especially if consumed in the morning or early afternoon. However, compared to coffee, which has nearly twice as much caffeine, the effects are milder.
If you’re sensitive to caffeine, drinking Earl Grey in the evening might affect your sleep. For those looking for a more relaxing experience, decaf Earl Grey or herbal alternatives like Rooibos Earl Grey are great options.
Caffeine Sensitivity and Individual Reactions
Not everyone processes caffeine the same way. Several factors influence how your body reacts to Earl Grey’s caffeine content:
- Metabolism – Fast metabolizers process caffeine quickly, leading to a shorter energy boost.
- Caffeine Tolerance – Regular coffee or tea drinkers may feel less impact from Earl Grey’s caffeine.
- Time of Consumption – Drinking Earl Grey in the afternoon or evening might interfere with sleep, especially for those sensitive to caffeine.
If you experience jitters, restlessness, or trouble sleeping, try reducing your steeping time or switching to a low-caffeine blend.
Health Benefits of Moderate Caffeine Intake
Earl Grey tea, which contains caffeine, offers several health benefits when consumed in moderation. Key benefits of its caffeine content include:
Antioxidant Activity: Earl Grey tea contains catechins and other polyphenols, which possess strong antioxidant properties that help protect cells from oxidative damage.
Enhanced Cognitive Function and Alertness: Caffeine intake of 3-6 mg/kg body weight per day has been shown to improve cognitive function, alertness, and mood in adults.
Neuroprotective Effects: Regular moderate caffeine consumption from tea may offer neuroprotective benefits, potentially reducing the risk of cognitive decline and neurodegenerative diseases.
That said, too much caffeine can lead to side effects like anxiety, insomnia, or increased heart rate. To avoid these issues, stick to 1–3 cups per day, depending on your caffeine tolerance.
Choosing the Right Earl Grey Tea Based on Caffeine Needs
High-Caffeine Earl Grey Options
If you’re looking for an energy boost but don’t want to drink coffee, some Earl Grey blends have extra caffeine. Certain brands add tea extracts to increase caffeine levels.
Popular high-caffeine Earl Grey options include:
- Zest Tea Earl Grey – 150mg of caffeine per cup (more than coffee!)
- Stash Double Bergamot Earl Grey – Higher caffeine than regular Earl Grey
- Tazo Earl Grey – Bold black tea blend with moderate caffeine
These stronger blends provide a morning energy kick without the jitters of coffee.
Low-Caffeine or Decaffeinated Alternatives

- Green Earl Grey – Offers a milder 30–50mg of caffeine
- Rooibos Earl Grey – Caffeine-free with a similar citrusy taste
If you love the bergamot flavor but want to avoid caffeine, herbal substitutes are your best bet.
Tips for Controlling Your Caffeine Intake with Tea
Want to enjoy Earl Grey without overloading on caffeine? Here are some simple tricks:
✔️ Steep for Less Time – A shorter steep (1–3 minutes) extracts less caffeine.
✔️ Use Fewer Tea Leaves – A lighter brew means less caffeine per cup.
✔️ Opt for Blends with Green or White Tea – These have naturally lower caffeine.
By choosing the right Earl Grey tea, you can tailor your caffeine intake to match your energy needs.
