| Recent Japanese imports: Godzilla & GABA* |
Within a few weeks of purchasing our first GABA tea, we were at an IMAX theater watching Godzilla Minus Zero. While it's true these two products from Japan deliver on opposite sides of the emotional spectrum, they actually pair well together: while one terrifies, the other calms.
First the tea. . .
A recent trip to Zingerman's Deli in Ann Arbor introduced us to yet another tea discovery: GABA. GABA is a type of tea processed under oxygen-free conditions to dramatically increase its concentration of gamma-aminobutyric acid, a compound that functions as a calming chemical messenger in the nervous system. It's a naturally occurring neurotransmitter that helps with relaxation.
The basic idea behind GABA tea is, the more you take in of this compound, the calmer you will feel. And, good news for those who may be partial to one type of Camilla sinensis, any tea variety can be turned into GABA tea through a special processing method.
First developed by Japanese researchers in 1987, it's become increasingly popular worldwide for its smooth flavor and potential health benefits.

How a tea becomes GABA:
The key difference between GABA tea and regular tea is an anaerobic processing step. After harvesting, tea leaves are sealed in nitrogen-filled chambers that remove all oxygen. This triggers a natural biochemical reaction inside the leaves: an amino acid called glutamic acid converts into GABA at much higher rates than normal.
What can be called GABA?:
To be
commercially labeled as GABA tea in Japan, the finished product
must contain at least 150 mg of GABA per 100 g of dried tea leaves.
The other major producer of GABA is Taiwan, (particularly GABA oolong), but, unlike Japan, there is no official national standard. It's nice to know, though, that most Taiwanese tea farmers follow the same Japanese benchmark.
Does GABA tea really calm one down?
Though research studies are not overly abundant, anecdotally, many regular drinkers of GABA describe a sense of "calm alertness". While tea's caffeine is typically less than the jolt coffee provides, a tasty tea brew can still be a stimulant. However, tea with GABA is said to provide balance and mellow out the jitters.
How to Prepare GABA:
You can use a small pot or gaiwan in the traditional Chinese gongfu style or, the method we used, our Breville, set to 205 degrees for a 4-minute steep, though instructions vary. The good news is, don't fear your settings too much. Because the flavor profile is naturally sweet and low in bitterness, GABA tea is more forgiving of slight over-steeping than most greens or light oolongs.

Godzilla vs Ghidorah:
Godzilla Minus Zero is a 2 hour and 15-minute sensory overload, featuring not one, but two gigantic creatures with a total of four heads. In an IMAX theater this weekend, together with family, we watched, these two threatening behemoths expand and stomp to the loud and vibrating bass beat. Defying bombs and other high-level artillery, these two angry brutes destroy everything in their path with no apparent reason. Perhaps they could benefit from a cup or four of GABA.
Recommended pairing:
We believe GABA makes a perfect pairing with Godzilla Minus One with its "calm alertness" properties to soothe you threw the terror and, with over two hours of runtime, keep you alert in between the stomping.
Our tea was Zingerman's GABA oolong. Oolong is the most common variety and is often described as having a rich, smooth body with "honey-like sweetness and very low astringency".
