Oolong Processing
November 24th, 2008Oolong processing is above all a labor of love. When harvesting begins, everything else stops. I once spoke to a couple of young lovers whose families were tea farmers; they told me they had to postpone their wedding by two weeks because the harvest started early that year. Tea harvesting first, marriage second.
Now, let me preface this short blog entry by saying that there have been and will continue to be books, annals, tomes even written about oolong processing, and what I would like to do here is give you just a taste of what it involves, looks like, smells like and means to the tea industry.
The oolong processing I have witnessed and learned about has been of both Taiwanese and Chinese oolongs. I have studied Taiwanese Baochong tea processing and Dong Ding high mountain oolong processing. And I was also on Phoenix mountain in China, and learned about Dan Chong processing as well as traditional charcoal style roasting of Ti Kuan Yin tea. Today, I will detail Taiwanese Baochong tea processing, probably because I just have more pictures to share of this processing. Then later I will continue with other processing styles. I think charcoal roasting is probably my favorite kind of processing, but let’s begin here for now.
Baochong tea is grown best at between 500-800 meters. High altitude and misty mornings help develop the chlorophyll in the leaves, and terracing helps the farmer get to the tea, fertilize and pick the leaves. The soil can sometimes be clay like, and here is a picture of the soil where our Baochong tea was grown.
Baochong tea leaves are preferably picked by hand. However they can be harvested CTC (cut, tear, cut). This harvesting is with a hand held lawnmower-type machine. It has what can best be described as a butterfly catcher on the back of it to catch the leaves as they are cut. Here are two photos detailing handpicking and CTC harvesting. See the difference?
When the tea is picked by hand , it’s picked by women who are usually over 45. I have even seen women as old as 98 picking tea. They harvest tea not because they have to, their families take care of them. They do it because they enjoy doing it, have little else to do to entertain themselves in a farming community, and are highly respected, and still valuable to the industry and to their communities. So they join in. All the Taiwanese tea pickers I have encountered are highly skilled and very fast at what they do, and thus are given quite a bit of respect. They are picked up in their village in the morning, and taken over to the tea farm, where they are provided breakfast, tea (of course), they do their daily tea picking, offered lunch and given a lift home. Baochong tea pickers carry their basket of tea leaves to the end of each row on the terrace and deposit it there, they do not carry a heavy load from one row to the next. Unlike work on big industrial farms, these tea pickers are not subject to carrying heavy loads for hours at a time.
Weather conditions play a large role in tea processing too. Taiwanese Baochong tea processing is guided by help from the farmer’s almanac. When the almanac indicates processing season has arrived and the window of those precious few days to pick oolong is here, the farmer carefully studies the soil, the length of the tea’s leaves as they grow day by day, the subtle differences in the afternoon lifting of the fog, all these play into the decision of when exactly to pick. A day early, and an astounding difference in quality can be seen, either for the better or worse. Last year’s Baochong Red Circle carried was far better than this year’s tea from the same farmer. Picked one day early, the leaves looked identical to last years, but the brew was weak, straw-like and dry in the throat. Thus, we went to different farmers to try their teas (see our post from 5 Generations on Wenshan) . When we finally found the taste we were looking for, we asked, did you pick early? No, replied the farmer, I picked this tea on the same day as I did last year. A gamble can pay off, or not, depending largely on Mother Nature, and a farmer’s attention to detail. Happily, we had chosen a new tea for our menu that surpassed last years crop and was also a competition winning tea - lucky us!
Processing begins after picking when the leaves are withered. Again, depending on the weather, they could be withered in direct sunlight, under shade, on the hot tarmac of the roadside, or indoors. The farmer will know how withering the tea will compliment the early or late picking and just how this will affect the rest of the processing as well as final outcome of an individual batch of tea. Here is a covered area where tea is withered.
Then the tea is racked and awaits the “green killing” machine. This machine is like a large tumble dryer that “sets” the tea’s oxidation level, and it’s the reason why green teas don’t turn brown or black with time, because they’re “set”.
Next, Baochong tea is put in a tumbler. This tumbler lightly bruises the tea leaves, bringing out more of the leaf’s juice, aiding in oxidation. It also bruises the leaves in a style that gives a classic “golden halo” to the leaf, and if done properly is a sign of good processing technique.
Then the Baochong is twisted. Baochong literally means “wrapped kind” because it is wrapped like this (picture) not rolled like this (picture).
The rolling and re-rolling and fluffing and more rolling can be repeated up to two dozen times to achieve the desired shape. This is where time, patience and an expert hand have a great chance to express themselves, resulting in an acceptable cup of tea or a cup of tea worthy of acclaim. This is also the tiring part where a farmer might not sleep for one or two nights, depending on how the harvest is going.
Lastly, the tea is baked insert (picture) and thus, Mao Cha or Raw Tea is achieved. When toasted 10-15% the tea is at it’s finished state.
This is the point at which Baochong tea destined for export tea is blended for a specific flavor profile, packaged in bulk and shipped off. But higher grades, those that are single estate harvested, are submitted to the Wenshan Baochong competition for comparison and scrutiny, and ultimately to select a Baochong that is to be the gold standard of the 5 criteria judges use to ascertain what a truly good tea is: dry aroma, wet aroma, color, taste, and leaf size.
