Beginners Guide To Tea Series: Green Tea And Its Benefits

Paint With Teas

If you thought black tea packs a punch, wait until you find out about another type of tea known as green tea. Green tea has a double identity, one of which most of us are unaware of. This “other” entity hides behind a veil that fools us into thinking it is oh so mild and delicate.

Beware because once you take that first sip, a powerhouse of something unexpected begins to flood your body!

What Is Green Tea?

Green tea is the purest form of tea because it does not go through oxidation or additional processing that other teas (especially black tea) do. It is perhaps the closest thing you’ll get to an unadulterated natural tea. Green tea makes up the largest group of tea types and comes in hundreds of varieties.

Many tea drinkers opt for green tea because it’s the most beneficial type of tea among all teas. It’s how green tea is processed that protects the integrity of the tea leaf, which in turn is responsible for preserving beneficial polyphenols, flavonoids, and catechins.

Where Did Green Tea Come From?

Whether it’s green, black, oolong, yellow, or white, tea begins its journey through the sprouting of new tea leaves on the tea plant (Camellia sinensis.) Various tea plantations scattered throughout the world grow these tea plants with a very precise goal in what type of tea they will make.

Green tea makes up for the largest portion of the tea industry, with black coming in second. The majority of green tea is grown in Asia; however, other countries such as Africa, India, Nepal, and the U.K. also grow and process it.

How Green Tea Is Processed

Let’s take a look at the journey of green tea from the moment the tea leaf is picked to the moment it is packaged and off to market.

Harvesting (Plucking)

The harvesting (known as a “flush” in the tea industry) and minimal processing methods are what produce green tea. Unlike black tea or any other type of tea, it’s the lack of doing too much to the harvested tea leaves that make this tea as pure as it is.

Plucking is the first step in harvesting the tea leaves. Pickers go out into the tea fields (during a flush,) where they hand pluck buds/tea leaves which are then placed into a basket. Once the harvesting is completed, the baskets full of tea buds/leaves are taken back to a processing plant.

Flushes play a significant role in the taste of green tea. The first flush of any tea is always considered the premier and most prized tea. It is purest in taste, offers the most health benefits, contains the highest amount of caffeine, and unfortunately, costs the most.

Why Countries Harvest By Flushes

Not all countries have flushes; some harvest year-round because of a conducive climate. However, in countries where seasons limit harvesting, flushes are followed. Flushes produce a certain quality of tea.

1st Flush

Premium tea

Cost: Most expensive

Flavor: mild, sweet

Astringency: lowest

Caffeine: highest

Health Benefits: highest

  • Newly sprouted leaf buds are plucked. These tender leaves are the ones that have been dormant all winter.
  • These new leaf buds are the sweetest and contain the least amount of tannins.

2nd Flush

High-quality tea

Cost: Expensive

Flavor: stronger

Astringency: mild

Caffeine: high

Health Benefits: high

  • Some leaf buds are still remaining. The bud and a few of the first leaves are plucked.

3rd Flush

Inexpensive tea

Cost: Inexpensive

Flavor: mild to bitter

Astringency: high

Caffeine: low

Health Benefits: low

  • This is the busiest harvest because the tea leaves are taking off in abundance.
  • Tea leaves plucked during this flush go on to be infused to offset the bitter astringency.

4th Flush

Affordable tea

Cost: Cheap

Flavor: diluted

Astringency: highest

Caffeine: lowest

Health Benefits: lowest

  • There is still quite a bit to harvest.
  • The tea leaves are mature, which produces a “bite” in taste.
  • Tea leaves plucked during this flush go on to be infused or blended in with other teas.

Flushes in China, Japan, and Korea occur at different times than other parts of the world, such as India, the U.K., or Africa. Asian cultures harvest tea according to the lunisolar calendar. For those of us who may not be acquainted with Asian culture as it relates to the lunisolar calendar, it can be confusing to understand how tea is harvested according to lunisolar terms and numerical terms.

Chinese Flush

Tea plantations in China typically follow the lunisolar calendar to harvest tea. However, it’s not uncommon for teas grown at higher elevations to be harvested at other times.

Types Of Green Tea

There are more varieties of green tea than we can possibly list. The different ways that green teas are processed, various infusions, blends with other tea, and brewing methods are what provides the multiple dimensions of flavor, aroma, and overall benefits that green tea is known for.

For example, Hojicha green tea gets its well-known smoky flavor from it being roasted over a fire. Green jasmine tea is painstakingly infused over months and months with infusions of fresh jasmine flowers to give it the lovely floral aroma and fragrance.

A Few Green Tea Specifics

When shopping around for a good green tea, there are a few things to keep in mind. A good quality green tea will have the origin noted on the packaging. If you don’t see this information on the package, chances are the tea is of poor quality. Loose leaf tea is the best way to experience any tea at its best because the grade of tea is of better quality.
