Green Tea vs. Black Tea: What You Should Know About These Popular Teas

Posted by Aiya Matcha on Jun 16th 2020

Did you know that tea is the most widely consumed drink in the world? Packed with tons of health benefits, this beverage has always been a delicious staple with staying power. While it is true that all tea comes from the same plant, this does not necessarily mean that all tea is fundamentally the same. Join us as we take a closer look at the two most popular tea varietals: green tea and black tea.

What is Green Tea?

Green tea is a varietal of tea that is made from unoxidized leaves of the Camilla Sinensis plant. When eastern cultures talk about tea, they are generally referring to green teas, such as Matcha green tea, Sencha green tea, or Jasmine green tea. This type of tea is most commonly consumed in China and Japan, as a daily source of antioxidants during meals.

Processing of Green Tea

Like most teas, green tea stems from the Camilla Sinensis plant. When the tea leaves are ready for harvest, it is minimally oxidized to keep its fresh-picked, bright green color and light, vegetal flavor. Compared to black tea, green tea has less caffeine with about 20 to 40 mg of caffeine per 8-ounce cup.

Origins of Green Tea

Among all teas, green tea originated in China. One popular legend suggests that Shennong, the Emperor of China and supposed inventor of Chinese medicine, discovered tea around 2700 BC when a fresh tea leaf from a nearby tree fell into his cup of boiled water.

Popular Types of Green Tea

Over time, green tea has drastically grown in popularity. Notably, China and Japan dominate the market in the production of green tea. The four most popular types of green tea are Sencha, Matcha, Jasmine, and Longjing (or “Dragon Well”).


Sencha is the most popular type of green tea produced and consumed in Japan. This tea type is known for its refreshing and uplifting essence. Sencha is described to have a light grassy and earthy flavor.


Jasmine tea is scented with the aroma of Jasmine blossoms resulting in a subtly sweet and highly fragrant tea. Due to its powerful fragrance, this type is the most famous scented tea in China.


Matcha is a Japanese green tea that is stone-ground into a fine powder and whisked in hot water instead of steeped. The high content of chlorophyll and amino acids as a result of shade growing, give Matcha its unique rich vegetal taste, followed by a lingering sweetness.

Longjing ("Dragon Well"):

Longjing, directly translated to “Dragon Well”, is another popular green tea in China. It is known for its sweet, well-rounded flavor that is often described as “reminiscent of freshly roasted white corn.”

What is Black Tea?

Black tea is a varietal of tea that is made from oxidized leaves of the Camilla Sinensis plant. When western cultures talk about tea, they are often referring to black teas, such as sweet iced tea, English breakfast tea, or Earl Grey tea. This popular type of tea is known for its strong, robust flavor that can shine through lots of sweeteners, creams, and other ingredients.

Processing of Black Tea

Similar to green tea, black tea grows from the Camilla Sinensis plant; however, the oxidation process that it undergoes after being harvested differentiates it from other varietals. The oxidation process consists of a series of chemical reactions that brown the tea leaf, which affect the tea’s taste, aroma, and chemical compounds. Sometimes referred to as fermentation, oxidation creates a bold malty, smoky, or fruity flavor depending on the intended tea type. In addition, this process also increases the natural caffeine content found in tea, resulting in 40 to 70 mg of caffeine per 8-ounce cup.

Origins of Black Tea

Prior to the mid-17th century, all tea in China was green tea. Due to the increase of foreign trade, Chinese growers needed a way to preserve their tea during their long travels. They found that oxidizing the tea leaves would help retain its freshness and flavor over a longer period. Thus, the introduction of black tea.

Popular Types of Black Tea

Today, black tea is grown and produced all over the world across various geographic locations and climates. The four most popular types of black tea are Keemun, Assam, Darjeeling, and Ceylon.


Keemun is the most popular black tea consumed in China. This tea is relatively light in flavor with fruity and smoky notes in the aroma and a gently malty non-astringent taste reminiscent of unsweetened cocoa.


Darjeeling is a popular tea produced in India and is known for its musky sweet tasting notes similar to Muscat wine. This tea is often used as the base for the popular beverage, Chai tea.


Assam, along with Darjeeling tea grows exclusively in India. This tea is known for its body, briskness, and malty flavor. Due to its bold flavor, Assam is often blended with milk and served as a creamy breakfast tea.


Ceylon black tea, also known as Sri Lankan tea, is known for its strong brisk flavor and bright appearance. This black tea contains notes of citrus, chocolate, and spice, similar to cinnamon.
