1. Understanding Green Tea
Before delving into a comparison of caffeine levels, it’s crucial to understand what green tea is. Green tea comes from the Camellia sinensis plant. The specific part of the plant used determines the type of tea produced.
Will Battle, Managing Director at Fine Tea Merchants Ltd, explains that green tea is distinguished by the deactivation of enzymes, preventing oxidation.
“Green tea is steamed or pan-fried to prevent oxidation, differentiating it from black tea, oolong, or other tea types,” he notes.
Francois Mathieu, co-founder of Hojicha Co, highlights that green tea is not defined by its color but by its production method.
The method to keep tea green varies depending on the region:
- Japan: Steaming is commonly used.
- China: Pan-firing is prevalent.
Both of these methods prevent the tea from oxidizing and turning black.
1.1 Different Green Tea Varieties
Green tea encompasses a wide variety of types, distinguished by growing methods, harvest timing, and processing techniques.
Francois points out, “In Japan, sencha is very popular, harvested early with younger shoots.”
He adds, “Bancha, another Japanese green tea, is harvested later in the year and is considered a lower grade.”
Matcha has also gained significant popularity worldwide.
Francois explains, “Matcha involves shading the tea plant to produce different chemical reactions, followed by removing twigs and grinding, resulting in a distinct product.”

2. Caffeine Content Comparison
Caffeine stimulates the nervous system, muscles, and heart by producing neurotransmitters. These neurotransmitters, like theophylline, paraxanthine, and theobromine, bind to brain receptors, blocking adenosine, which typically induces sleep, leading to alertness.
Caffeine levels in coffee depend on bean type (arabica versus robusta), roast profile, brewing method, and water temperature. The same applies to green tea.
Will states, “According to FDA estimates, an 8oz cup of coffee contains 80 to 100mg of caffeine, while an 8oz cup of tea contains about 30 to 50mg.” He also notes, “However, the ratio of liquid to solid raw material differs.”
2.1 The Importance of Dosage
Will explains that green coffee beans have less caffeine than green tea leaves per gram, although a cup of coffee usually contains more caffeine overall. This is because more coffee is used for brewing than green tea leaves.
Francois mentions, “There’s a graph on our site comparing Japanese green teas with coffee.” He adds, “Japanese government data indicates that coffee generally has higher caffeine levels than green tea.”
Factors like species and roast profile influence caffeine content in coffee, while intensity, concentration, and TDS (Total Dissolved Solids) affect caffeine levels in each cup.
These factors also apply to green tea. For example, the high surface area of matcha allows for greater extraction of chemicals, including caffeine. Loose leaves require longer steeping times to achieve similar caffeine levels.
Francois notes that the part of the plant used also matters.
“Younger shoots at the top of the plant, found in matcha and sencha, have higher caffeine levels,” Francois explains. “Mature tea leaves lower on the plant have lower caffeine levels.”
Green tea harvested early in the season generally has more caffeine than later harvests.

3. Biological Factors Influencing Caffeine Absorption
Will explains that caffeine absorption also plays a critical role in experiencing the effects of each beverage, not just the amount of caffeine.
“Coffee creates a sharp peak for an immediate impact, whereas tea is absorbed more gradually in the intestines,” he states.
Francois highlights L-theanine, which some studies suggest has a relaxing effect on the brain, muting the impact of caffeine.
He adds that discussing caffeine per gram in green tea misses a key point. L-theanine, an amino acid, promotes calmness. Research indicates that combining it with caffeine can improve cognitive abilities.
“The combination of alertness and calmness allows you to focus on tasks without stress,” he says.
3.1 Additional Considerations
The interplay between caffeine and L-theanine is a critical factor in the overall experience of drinking green tea compared to coffee. This unique combination provides a sustained and balanced energy boost, which is one of the primary reasons people choose green tea.
4. The Significance of Caffeine Content in Green Tea
While coffee is well-known for its caffeine content, green tea appeals to a different market. Will notes that educated green tea consumers appreciate its unique mouthfeel, flavor, and aroma, much like coffee.
“Green tea also offers health benefits from catechins, particularly epigallocatechin gallate (EGCG),” he adds.
EGCG’s anti-inflammatory and antioxidant effects contribute to green tea’s reputation as a healthy beverage.
Francois explains, “Some people seek the health benefits of antioxidants in green tea, while others look for the caffeine and L-theanine combination. Many simply enjoy the flavor. There are many reasons to consume green tea.”
4.1 Consumer Preferences
Consumer preferences vary widely when choosing between green tea and coffee. Understanding these preferences helps to highlight the unique qualities of each beverage.

| Sencha | 28-30mg | Most popular green tea in Japan, known for its balanced flavor and aroma. |
| Gyokuro | 35-40mg | Shade-grown, resulting in a sweeter, less bitter taste with a higher caffeine content. |
| Bancha | 10-20mg | Harvested later in the season, lower grade with a mild flavor and lower caffeine content. |
| Hojicha | ~20mg | Roasted green tea with a unique smoky flavor, typically lower in caffeine compared to other green teas due to roasting. |
