Green tea from Japan differs quite a lot from its Chinese cousin. The different cultivars, harvesting, and processing provides a distinct experience. It can also be challenging to steep. Many folks I’ve encountered have found their first experience with grassy bitter Japanese green tea to be their last. With this post I hope to provide those people and others with inspiration to give this amazing style of tea a second chance.
While the steps below may seem complicated, if you understand some of the principles of how tea steeps, it all makes sense. First of all, Japanese tea tends to be machine-harvested, which results in smaller and more broken leaves. Broken leaves mean that the tea will infuse much more quickly and can become bitter in much less time than a full leaf Chinese green.
Furthermore, unless passed through a fine mesh strainer, it’s likely that many of the leaves will end up in the cup when it’s done. These leaves will continue steeping the tea as it cools and may cause unwanted strength even if the timing is just right.
Finally, Japanese green teas are generally steamed to fix the leaf rather than pan-fired or baked as they are in other countries. This results in a tea liquor that’s much more “vegetal” in the same way that steamed vegetables tend to be “greener” tasting than those same vegetables when fried. If the infusion is too strong, the result can not only taste bitter, but grassy as well.
In essence, Japanese green teas are much more delicate and need a little more care when preparing them. Here’s my suggestions for most styles of Sencha, as well as Kabusecha and Gyokuro (Genmaicha, Hojicha, Kukicha, and Matcha are a different matter).
1. Use a mesh strainer
Because of the small and broken leaves we ideally need to use a mesh strainer. Japanese Kyushu pots usually have these built-in, but such pots can be hard to find on the Western market. Another option is the ceramic “teeth” on the lip of a Shiboridashi pot which are designed to catch the small leaves as the liquor pours over the rim. Lacking these tools, any wire mesh strainer will do the job, even a large kitchen strainer. If you don’t have any strainer on hand, just be aware that the tea will continue steeping in the cup and you may want to reduce the infusion time to compensate.
