What’s the difference between black and green tea? 


In this article, we’ll deep dive into the differences between these delicious teas and the benefits they bring to tea lovers around the world. 

The History and Origin of Black Tea

Black tea's origin can be traced back to the Ming Dynasty in China (circa 1590).

The first black tea (Lapsang Souchong) emerged accidentally when tea leaves were left to be oxidized for longer than usual. The excessive oxidation resulted in the formation of black tea leaves that developed a strong flavor.

The Wuyi region in China possessed the perfect conditions for mass production of black tea. Approximately 285 years later, an alternative black tea to the Lapsang Souchong was produced called Keemun.

Black tea made its way to Europe in the 17th century via Dutch traders. They introduced black tea in 1610 as an exotic and luxurious drink to be enjoyed by the European elite.

Britain, arguably most well-known for its love for tea, first tasted black tea and was introduced to it by Princess Catherine of Portugal after marrying King Charles ll.

At this point, black tea was still restricted to the elite. Eventually, tea prices fell and became widespread among the working class and is enjoyed by millions daily.

Black tea is cultivated in multiple regions, including:

  • Kenya is one of the highest black tea producers around the Great Rift Valley.
  • In the Yunnan, Guangdong, and Fujian provinces in China.
  • Sri Lanka (known for Ceylon tea).
  • India (Assam and Darjeeling).
  • Bangladesh
  • Argentina
  • Vietnam
  • Malawi

Black tea cultivation begins with seeds or vegetative cuttings grown in nurseries for 12–16 months until they develop into hardy plantlets ready for transplanting.

Tea estates prepare the land by clearing, tilling, and creating terraces on slopes to prevent soil erosion.

Drainage and irrigation systems are established.

Plantlets are planted in rows spaced 0.6–1.2 meters apart, with plants spaced 0.6–1 meters apart in the rows. The plants take 3–5 years to mature for commercial harvesting.

Tea bushes require regular pruning, fertilizing, weeding, and pest management to ensure optimal growth and yield. The bushes are typically pruned annually.

The young shoots (two leaves and a bud) are carefully hand-picked every 7–15 days during peak growing seasons. Harvesting is labor-intensive and accounts for a significant portion of production costs.

The History and Origin of Green Tea

Green tea has been around for thousands of years longer than black tea. 

The earliest credible records suggest that green tea was first consumed during the reign of Emperor Shennong around 2737 BC.

Green tea was also an accidental discovery.

A legend states that Emperor Shennong discovered green tea when leaves from a nearby Camellia sinensis plant fell into his cup of boiling water.


Green tea wasn't always consumed in the way it is today.

In the 3rd century AD, people consumed green tea by chewing on fresh green tea leaves. It wasn't until the 6th century AD that tea drinking (as it is commonly known today) became widespread, with the publication of the first book entirely about tea—"The Classic of Tea" by Lu Yu.

Green tea remained a popular staple in East Asia, spreading to Japan in the 9th century AD. The Japanese added their unique touch to green tea by creating varieties like sencha and matcha.

A white ceramic teacup filled with light Sencha Kyoto Green Tea rests on a uniquely shaped white saucer. Loose green tea leaves, rich in antioxidants and known to boost metabolism, are scattered around the saucer and teacup on a soft pink background. The image is well-lit, highlighting the texture of the leaves and the tea's color.

Astonishingly, Europe didn't taste green tea for another 1,000 years!

In the 19th century, European explorers exported green tea, and its popularity rose due to its health benefits, such as improving heart health and reducing blood pressure.

Fast forward to the present day, and green tea production largely remains in East Asia, with major production centers in China, Japan, India, and Sri Lanka.

Cultivation involves meticulous care and attention to the tea plants and leaves. The seeds or cuttings are grown for up to 16 months until they develop into hardy plantlets planted in tea gardens or estates approximately 1.2 meters apart.

The young tea bushes require 4–8 years to reach maturity.

Regular fertilizing, pruning, pest management, and weed control are essential for optimal growth during this period.

In Japan, some plantations employ shade cultivation techniques like portable shade structures.

The youngest leaves and buds are carefully hand-picked every 7–15 days during the peak growing seasons, typically in spring and early summer when the flavor compounds are most concentrated. 

Within 24 hours of harvest, the fresh leaves undergo processing to prevent oxidation and preserve their green color and fresh flavor. This involves heating the leaves, either by steaming (Japanese method) or pan-firing (Chinese method), to deactivate oxidizing enzymes. 

The leaves are rolled, shaped, dried, sorted, and packaged.

How to Prepare Green Tea

There are three ways to prepare green tea.

Infuser Method

  1. Measure one teaspoon of green tea per cup of water.
  2. Place the green tea leaves in the infuser and set the infuser inside your teapot or teacup.
  3. Heat water to just below boiling (175–185°F/80-85°C).
  4. Place the infuser in the hot water and let the tea steep for a maximum of 3 minutes.
  5. After three minutes, remove the infuser and enjoy your tea.

Strainer Method

  1. Place loose green tea leaves directly into your cup. Use one teaspoon per cup of leaves.
  2. Heat the water to just below boiling and pour it over the tea leaves, allowing 2–3 minutes of steeping.
  3. After steeping, pour the tea through a strainer into another teacup to separate the leaves from the liquid.

The strainer method gives the leaves more space to unfurl and release their flavors, resulting in a well-rounded cup of green tea.

Tea Bag Method

  1. Place one green tea bag into your cup.
  2. Heat water to just below boiling point and pour it over the tea bag, allowing 2–3 minutes of steeping.
  3. After steeping, discard the tea bag and enjoy your cup.

You can adjust your steeping time in all three methods depending on how light or strong you want your brew to be.

How to Prepare Black Tea

Black tea is prepared in the exact same way as green tea for each method. The only differences are:

  • Use black tea leaves or a black tea bag (depending on your chosen method).
  • Boil the water in each method to 200–212°F/93-100°C, as opposed to 175–185°F/80-85°C.
  • Keep the steeping time for each method between 3–5 minutes. You can reduce or increase the steeping time if you desire a stronger flavor.

Green and Black Tea Taste and Appearance Differences

Green and black tea have entirely different tastes and appearances due to how they're processed and their oxidation levels.

Green tea retains its green color and has a more delicate, often wiry or twisted look, while black tea leaves appear darker, ranging from dark brown to black, and are generally more tightly rolled. 

In terms of taste, green tea is fresh and light, possessing a vegetal flavor. This taste is preserved through the lack of oxidization. 

A copper teapot is pouring Magic Hour Assam Black Tea into a glass teacup placed on an ornate, round, golden tray. Next to the teacup, there is a pile of loose tea leaves known for their malty flavor and full-bodied character, a metal scoop, and a string of black beads with a tassel. The background is white with a soft shadow.

Green tea can also have subtle, sweet, floral, or nutty notes, depending on the variety. 

Black tea has a polar opposite taste because its leaves are heavily oxidized. The flavor is bolder and stronger, possessing malty, fruity, or spicy notes.

Black tea can also have hints of caramel, chocolate, or even smokiness, particularly in varieties like Lapsang Souchong. The taste is generally more astringent and full-bodied, making it a popular choice for those who prefer a more pronounced tea flavor.

Green and Black Tea Caffeine Content

Black tea generally contains more caffeine per cup than green tea, with an average 8oz cup of black tea providing 47mg of caffeine compared to green tea's 28mg. The caffeine content can vary based on factors such as tea variety, growing conditions, and preparation methods.

For instance, matcha green tea has 35mg of caffeine per half-teaspoon serving due to the consumption of whole leaves. Additionally, the oxidation process used to produce black tea extracts more caffeine than green tea's gentler processing.

The specific part of the tea plant used, and the surface area of the leaves exposed to water also affect caffeine levels, with broken leaves and tea bags typically containing more caffeine.

Shared Green and Black Tea Health Benefits

Green and black tea share several health benefits due to their rich antioxidant content. Some of the shared health benefits include:

  • Cardiovascular health benefits. They can help lower blood pressure, reduce cholesterol levels, and improve overall heart function.
  • Both contain antioxidants, such as catechins in green tea and theaflavins and thearubigins in black tea, which help combat free radicals and protect against cell damage.
  • Both could prevent certain types of cancer, such as breast and prostate cancer.
  • Due to their respective caffeine content and the presence of L-theanine, they support brain function by stimulating the release of mood-enhancing neurotransmitters.

Enjoy Your Tea Time

Both green and black tea are enjoyable to drink and have many health benefits.

Regardless of your preferred type of tea, you can't lose!
