The dried leaves above exhibit the premium batch of Red Jade #18 Black Tea being offered as batch 84 of the Eco-Cha Tea Club. This crop was picked in early July, while it was still immature and tender. Summer crops are the best leaf material for optimal results in a full flavored composition for Black Tea specifically. Stronger sunlight and hotter weather produce higher concentrations of catechins in the leaves, resulting in a fuller aromatic and flavor profile. Full oxidation of these compounds is necessary to achieve a balanced composition that is not overly astringent.

Batch 84 of the Eco-Cha Tea Club is a Red Jade #18 Black Tea from the historical Sun Moon Lake tea growing region of Taiwan. This cultivar, given the name Red Jade (紅玉) is registered as hybrid #18 by Taiwan's Tea Research and Extension Station. You can learn all about its background in our recent blogpost, but this Black Tea hybrid strain is unique to Taiwan, and was "born" in the 20th century. It has become quite popular over the last 20 years since it was first commercially introduced in the early 2000's.

Batch 83 of the Eco-Cha Tea Club is an Alishan Small Leaf Type Black Tea made by our source of Alishan High Mountain Oolong and Alishan High Mountain Jin Xuan Oolong. They picked some of their Jin Xuan summer crop when it was still immature. These young tender leaves from the second flush (summer crop) are ideal for making Black Tea. Jin Xuan is the name of Taiwan's most popular hybrid small leaf type tea.

Red Jade, a.k.a. Taiwan Tea #18, is a hybrid large leaf cultivar that is unique to Taiwan. The indigenous wild tea tree that grows naturally in the mountain forests of Taiwan was cross-bred with the Assam strain from India. This initially occurred naturally when the Japanese introduced the Assam strain to the Sun Moon Lake area of Taiwan in the early 20th century. Chinese immigrants to this area had already been cultivating the indigenous tea strain, which eventually cross-pollinated with the new Assam strain.

Taiwan's Tea Research and Extension Station has produced dozens of hybrid tea cultivars. But there are three hybrid cultivars created in Taiwan which are by far the most popular. These are Jin Xuan (Tai Cha #12), Tsui Yu (Tai Cha #13), and Four Seasons Spring.

We can see from the brewed leaves above that they resemble an Oolong Tea much more than a Black Tea. The bulk of the leaves still maintain their structural integrity, indicating that they have not been rigorously rolled, like a Black Tea would be. Only a portion of the leaf material was torn and squeezed to expose the sap, resulting in a more thorough oxidation. Most of the leaf material was treated with the skill and tact that an artisan Oolong Tea is made from. We feel that this is a more specialized batch of Hong Oolong in this respect.

While pure iced teas made from quality Taiwan loose leaf tea are amazingly satisfying and refreshing on their own, sometimes it's also nice to mix it up with some natural flavorings. Here are some suggestions on how to flavor iced teas for an added kick.

Eco-Cha first met Mr. Zhan in 2016, when we smelled tea being roasted beside the historical train station in Shuili — one of our favorite mountain towns in central Taiwan. We learned that he had been transitioning his family tea farm to natural farming methods for several years already. We said that we looked forward to learning more about his work, and hoped to have the chance to procure some tea! Well, some things take time... and 5 years later, here we are — finally able to share a batch of his tea with the Eco-Cha Tea Club!

Our Hong Oolong Tea comes from Meishan Township, Chiayi County, Taiwan. Meishan is the northeastern corner of the Alishan tea producing region, and in our perception, it generally offers the best Alishan Tea. So, even though Hong Oolong is not commonly made in this region, Eco-Cha (at long last!) has chosen this source for specific reasons.

Batch 60 of the Eco-Cha Tea Club brings us to a full five years of offering monthly editions of specialty Taiwanese teas! This month's edition was cultivated and crafted by one of our most respected sources of naturally farmed tea. He not only employs the most radical natural farming methods we know of, he also is continually refining processing methods to bring his produce to its fullest potential, based on the growing conditions of each season. Mr. Xie also produces our GABA Oolong Tea, which, like this month's batch, is one of his signature products.

Our source of Red Jade Black Tea (Tai Cha 18) is a success story in progress. And his most recent advancement in his operations has been to optimize the quality control of his Red Jade production. He is only using his prime summer produce for making his Red Jade Black Tea, and designating the early and late harvests for Ruby White Tea making. He has also begun to be more precise in timing of harvests, and picky (no pun intended!) about the selection of hand-picked leaves to reap only the proper degree of maturity in the new leaf growth. 

Batch #56 of the Eco-Cha Tea Club is a Pinglin Qing Xin Black Tea — summer 2019 harvest, from the same source as last month's edition of award winning Wenshan Baozhong Tea. This is the first batch of Black Tea we have sourced from the Pinglin region in northern Taiwan, and it is further supporting evidence of the fact that high quality tea can be made from low to mid-elevation farms. We were lucky to have sourced the remainder of two consecutive days of last summer's harvest that were combined to provide just enough to be shared with the Eco-Cha Tea Club! Black Tea reaches it peak of quality after at least one year of aging.
