Matcha Tea Tasting with Aoi Tea Company

Last week I had an opportunity to attend a matcha tea tasting with the Aoi Tea company.

It was educational to see how they taste and grade matcha.   To begin with, we looked at the tencha leaves.  The tea plants for matcha are grown under shade, and the tender leaves are harvested, immediately steamed and dried. Then the leaf part from in between the veins are used.This is tencha, before the leaves are ground.

I don’t know if you can see here, but there is a definite difference in the color of the leaves.  The pile on the left is a darker richer color green and is judged higher quality, the pile on the right is lighter and yellower and js judged lower quality.
The leaves are put into identical brewing vessels and filled with hot water, in this case about 150F.

The resulting brew is compared in color, aroma and taste.  The brew on the left is the lower quality leaves and the color was weaker, the taste more bitter.  The brew on the right, the higher quality leaves color was slightly darker, the taste much more complex and milder.  There was quite a difference in the fragrance of the leaves after brewing as well.

The tea is stored as tencha and when an order comes in, the tea will be freshly ground.  Matcha comes in 30 or 40 gram cans.  It can take an hour or more to grind enough tea for a can. Please store your matcha in the freezer or refrigerator.  Unopened the matcha will most likely be good up to a year. Once you open the can, it will last up to 30 days if stored in the refrigerator.   Opened cans of matcha will last maybe a week or so before they become oxidized.  If you are buying expensive matcha, store it in the refrigerator or freezer otherwise you are wasting your money.  Oxidized matcha that you don’t want to drink can be used for cooking or baking.

Fortunately, I don’t have to worry about storage.  At my house, a can of matcha once opened rarely lasts more than two weeks.

The Aoi Tea Company matcha will soon be for sale on the website.
