GABA Oolong (佳葉龍茶)

Harvest date: May 2017

High GABA content in this batch, over 280 mg per 100 g of tea. Our best batch yet in flavor and ptience (multiple steeps). Get it while it lasts, this is a special one.

The primary difference between GABA and other types of teas is the way it's processed. Most teas are categorized according to their processing and level of oxidation: black tea being fully oxidized; oolong being partially oxidized; green and white teas being unoxidized. Instead of being merely oxidized, GABA is exposed to a nitrogen-rich environment during processing. Japanese researchers discovered a few decades ago that this process enhances naturally occurring GABA in the tea. Since this discovery, GABA tea has become known and distributed for its health benefits.

GABA Tea was discovered by Japanese researchers in 1987. They were looking for a natural method to preserve food. They discovered that when allowed to ferment in a nitrogen rich atmosphere something magical occured.

The Japanese discovered that the levels of -aminobutyric acid [GABA] increase 5 to 10 times.

Zhi GABA Oolong contains copious amounts of GABA in a natural form, over 200 mg. per 100 grams of tea (Japanese Standard is 150). GABA is a naturally occurring human enzyme which functions as a calming and relaxing nutrient. It is now a daily health drink in Japan and only now making its way into the US.

We have procured a high quality organic version of this amazing tea.

The reason we drink it here at Zhi, though, really, is because of the taste. It has a wonderful deep fruitiness; very complex with Japanese Plum notes, and marked cinnamon notes, as well. It is a bit reminiscent of a bai hao oolong, but less woodsy/earthy and more fruity/rich. It has a very unique and easy-to-drink flavor profile that is a bit hard to describe, to be honest.
One of our good friends likens it to Guinness beer, a beer that has nitrogen in the carbonation. Thick mouthfeel and a certain molasses-y, creamy body and taste.

This gorgeous GABA Oolong tea was harvested in May 2017, and is stored in a vacuum seal.

    This is by far the best Gaba Oolong I have tried and I have tried many. I was impressed by the vacuum sealed packaging as a special touch to keep the tea fresh. I am really enjoying this tea and will order it from Zhi from now on. I kept looking for that special Gaba Tea and I finally found it!

    Amazing! I drink this tea twice a day and the leaves retain flavor for multiple steepings.

    I just tasted the new batch of GABA, and it is surprisingly different from the last.
    It has the same full-bodied structure with more prevalent cinnamon notes and a nice lean finish. This is a beautifully crafted tea!

    I enjoy GABA and it really make me fell better every time I drink it.
    I think the porduct loose a litle bit of the taste after a week of being openned, even in its own bag and in a closed and seal containner, so I allways buy small ammounts. Also, I think when it is young, it is much better.

    I'll order this again with relish. I've been drinking this in the morning, and three steepings gives me more energy than the sodas I had been drinking.
    Thanks Zhi.

Water: 195°F | Leaves: 1.5 -2 teaspoons per 6 ounce cup | Infusion Time: 3-4 minutes

Basic Steeping Tips
- Use filtered or spring water, whenever possible
- Don’t over-boil water
- Remove leaves after recommended time (adjust to taste)
- If you want stronger tea, use more leaves instead of steeping for a longer time.
Leaves can be re-steeped 2-3 times resulting in various flavor differences. Don’t throw out those leaves until they have given it all up!

GABA GABA tea was invented in Japan in 1986 when researchers were trying to find ways to preserve the freshness of raw tea leaves under a Controlled Atmosphere (CA), either vacuum or nitrogen-filled chamber. Somewhat accidentally, they found that the amont of r-aminobutyric acid increased significantly under such an environment. A 1987 paper further provided evidence that the liquor from the GABA tea can help alleviate hypertension by relaxing blood pressure. The GABA tea soon became popular in Japan.

The Japanese discovered that the levels of Gamma-aminobutyric acid [GABA] increase 5 to 10 times.
