Roasted Leafhopper High Mountain Oolong Tea

March 09, 2018

A leafhopper, the mystical bug behind "bug bitten tea."

Last November, Eco-Cha Tea Club members got to experience the original unroasted flavor profile of a Leafhopper High Mountain Oolong, also referred to simply as "bug bitten tea", or "yeh nah day" in the Taiwanese dialect. When we sourced that batch of tea, we conceived of a "secret" plan to first share half of this batch of tea unroasted, then roast the other half in order to give our members the opportunity to taste the difference between the unroasted and roasted versions of the very same batch of Leafhopper High Mountain Oolong Tea.

Xueba National Park in northern Taiwan

This batch of tea comes from the most recently developed High Mountain Oolong Tea producing region, located in northern Taiwan. Here in the industry, it is most commonly referred to as Guanwushan, in the vicinity of Xueba National Park (photo above). The rugged high elevation slopes of the northernmost central mountain range provide an ideal climate for High Mountain Tea production.

This crop was harvested in June, when the new leaf growth following early spring harvest was allowed to grow naturally. In effect, it was an invitation for the legendary Green Leafhopper to come and perform its magic. This tiny grasshopper-like insect likes to feed on the sap of the new leaves, which results in a chemical composition in the leaf that offers a unique honey-essence flavor in the tea. The Leafhopper is what creates the renowned Oriental Beauty Oolong Tea from northern Taiwan, and the subsequent Concubine Oolong produced in central Taiwan.

The tea leaves were allowed to oxidize significantly more than a standard High Mountain Oolong Tea. The effect of the Leafhopper, combined with a customized processing results in a particularly full-flavored, strong character.  Tea leaves of this constitution literally have more substance that results in a bold and complex flavor profile.

Brewing up some tea

Our dear friend who we first met over 20 years ago was kind enough to share half of the amount of tea that he sourced with us. He knows we are always looking for special batches of tea for our Tea Club, and invited us to come taste this one. He never says "Do you want some of this tea?", but the invitation to taste it is itself is his way of offering it. And when we asked him if he would be willing to roast half of our share, he did not hesitate.

After decades of managing his family farm, A-bao now specializes in tea roasting. He sources tea from many sources, and carefully considers the character of each batch and roasts the leaves according to his assessment. He roasted this batch of tea twice, for a total of nearly 20 hours, starting at less than 100°C and finishing at over 120°C. We are excited to be offering this educational experience of two versions of the same batch of "bug bitten" High Mountain Tea with our Tea Club members.

Wuyi was once the specialty tea cultivar of choice in the historical Songboling tea growing region in southern Nantou County. But it got replace with more prolific cultivars in recent decades. We are grateful to have a chance to experience this tea strain that really does stand on its own in comparison to the more popular strains. It has a robust character when made as a lightly oxidized, unroasted tea. And its hardy nature is able to withstand extensive roasting that other strains cannot.

Batch 62 of the Eco-Cha Tea Club comes from the same plot of tea as last month's batch. When we tasted this month's batch of unroasted Wuyi Oolong, following the heavily roasted batch that we shared last month, we were inspired to offer these two very different tasting teas back-to-back. Tasting these two batches of tea that were made from basically the same raw produce (different seasonal harvests), but processed differently, provides an educational experience on how significant processing methods are in determining the final product.

It is important to know how much caffeine you are consuming, but with so many different teas, sizes, and brands; it can be tricky to figure out exactly how each tea stacks up. 

Ready-to-drink bottled teas have caffeine values listed on the bottle, but how does the caffeine in ready-to-drink tea measure up with loose-leaf tea, or a tea bag? What about steep time? Is double the amount of tea double the caffeine? 

The Caffeine Calculator makes all this easy.
