Kill-Green in Tea Production

Have you ever wondered why Japanese green teas are so green? And why Chinese green teas are not as bright green, but are typically yellower? The reason lies in the processing steps for each tea and in particular the “kill-green” step of the processing some tea types.  The term kill-green is derived from the Mandarin shaqing (杀青), which means “killing the green.” Kill-green is also referred to as “de-enzyming” or “fixing” and is a process of tea manufacture used to halt the oxidative browning of tea leaves by denaturing the enzymes responsible for oxidation–  polyphenol oxidase and peroxidase. Think of

What is Green Tea?

The definition of green tea in it’s simplest and most generalized form is a tea that is made up of leaves that were prevented from oxidizing, shaped and then dried. However, green teas are not unoxidized. No tea is truly unoxidized because tea leaves begin to slowly wither and oxidize the moment they are plucked, something that is unavoidable since hours may elapse from the time of picking to the time of processing. So let’s draw a line here and speak only of controlled processes.  The most prevalent form of green tea production involves heating the leaves shortly after plucking (some

oxidation

What is Oxidation?

  Oxidation refers to a series of chemical reactions that result in the browning of tea leaves and the production of flavor and aroma compounds in finished teas. Depending on the type of tea being made, oxidation is prevented altogether, or deliberately initiated, controlled then stopped. Much of the oxidation process revolves around polyphenols and the enzymes polyphenol oxidase and peroxidase. When the cells inside tea leaves are damaged and the components inside are exposed to oxygen and mix, specifically when polyphenols in the cell’s vacuoles and the peroxidase in the cell’s peroxisomes mix with polyphenol oxidase in the cell’s

What is Withering?

  The moment a tea leaf is plucked from the tea plant, it begins to wilt naturally, a process we call withering. But once the tea leaves reach the processing facility, this process is controlled by the tea producer. The purpose of a controlled wither is to prepare the leaves for further processing by reducing their moisture content and to allow for the development of aroma and flavor compounds in the leaves. Controlling the withering process means closely monitoring humidity, temperature and air-flow over time. A controlled wither can occur outside with tea leaves laid out gently on bamboo mats

Wild Orange Pu-erh

Wild Orange Pu’er

These tiny oranges, known as clementines in the United States, are typically hollowed out and filled with tea, then aged. I have several that were obtained in Guandong, China, in 2005 and have since been aged in man-made pu-erh caves in the United States. The leaves, when steeped, have a zesty orange smell; the tea is smooth and malty, with hints of orange, especially if you use part of the rind while steeping. I was surprised that the orange notes were not more pronounced, but overall these make for a very interesting conversation piece and a very tasty tea. Here

Yunnan Black Tea: Golden Bi Luo

Golden Bi Luo

Yunnan black teas come from China’s Yunnan province and can be found in many different forms, this particular tea is comprised of twisted leaves similar to those found in Bi Luo Chun. Golden Bi Luo and other Yunnan black teas are best steeped for 1min at 195 in my opinion as it keeps the astringency at bay and the sweet notes in the forefront. Other Names: Hong Bi Luo, Yunnan Bi Luo, Golden Yunnan, Yunnan Golden Curls Origin: China, Yunnan Province Harvest: Spring 2011 Taste: Creamy with sweet, malty notes of vanilla. Behind the Leaf: Golden Bi Luo is a

Multiple Infusions: About Re-Steeping Tea

Why re-steep? Why not? Re-steeping tea really brings out the value of a tea, you can get many servings of tea from just one serving of leaves. More bang for your buck, and you get to taste the tea as it develops from steep to steep. Before you re-steep: If you are going to be re-steeping your tea, you don’t want to oversteep it. Re-steeping your tea means that you are going to be steeping the leaves multiple times which means that each time you steep it, you must remove the leaves from your tea and set them aside until

What is Yerba Mate?

Yerba mate is a tree. Not a tall one, but a moderately tall tree. In the farms they are not that big because they are pruned to make it easier to harvest, a similar method is used with the camellia sinensis plant for harvesting tea. The natives of this area, the Guaranies, discovered that they could make a drink with the plant, but they had to dried the leaves first. Yerba mate is poisonous if not dried. Not so poisonous that you will die, but you will wish to. It will give you stomach cramps, inflamation, diarrhea, intestinal cramps, incontinence and

The Importance of Doing Research for Your Customers

So many times I meet people that have been told erroneous information about tea. I have met countless people searching for certain teas that will cure certain disorders, from sleep apnea to arthritis. I drink tea because it tastes good, tea is not a medicine to me, and I don’t believe in selling tea as a “medicine.” I believe it is a deceptive practice, and one that many are susceptible to, If you knew nothing about tea and someone told you that it would help you lose weight, you would probably believe them, right?

Theanine: a 4000 Year Old Mind-Hack

Monks have been drinking tea for thousands of years to maintain a state of “mindful alertness” during long periods of meditation. But only in the last few years have studies shed light on why tea has this effect on the mind. The two elements responsible for this are caffeine and L-theanine, and it is the combination of the two that makes tea unique from any other drink. Spare Me the Science: What L-theanine and Caffeine can do for the Mind Promote a mindful state of relaxation Increase our ability to multi-task, and multi-task well Increase speed of perception Increase performance
