What is
Green Tea?

The Original Category of Tea.

Green tea was taken out of wild and into agriculture after it was identified by ancient humans to have medicinal qualities.  The original green teas were sun dried and over millennia it has evolved into the sub-categories of green tea that we know today.
Within the various types of green teas, nuances of region, season of harvest, leaf style and the plucking standard are evident in the flavor profile of each tea. This makes green tea a broad category and a main stay in East Asian tea culture.

Green Tea Firing

Green tea is the least oxidized of the six tea types. Green teas are crafted with the application of heat in a step called firing. This heat denature the enzymes that cause tea leaves to change in color from green to yellow, to red and final brown in a natural process known as polyphenolic oxidation. Firing neutralizes these enzymes, halting oxidation and fixing the green color. This is what gives the category “green tea” its name. The degree of oxidation that is allowed before firing is the primary defining characteristic used to distinguish the six tea types. 

In Japan, firing is most often conducted with steam heat, which rapidly blanches the tea leaves and fixes their bright green color. By comparison, in China and other origins, “dry heat” techniques such as pan-frying, tumble-roasting, oven-baking, and sun-curing are used.

Steamed green teas typically have a more vivid green color and umami-rich tasting notes such as “nori seaweed.”Green teas that are fired with one of the dry heat methods typically develop a more floral or nutty character. For instance, “toasted chestnut” is a common taste descriptor for pan-roasted Chinese green teas. After firing, the leaves are shaped to create a variety of green tea styles, each with its own character, flavor and aroma.

Origins of Green Tea

Green teas as we know them today were originally developed out of more rustic styles of sun-dried tea, around the time of China’s ancient Song dynasty (960 – 1279 CE). Today, most green tea is grown in China, Japan and Korea, with an increasing amount grown in Southeast Asia. Whatever the region, the most sought-after green teas are those picked in springtime.
