The standard level of matcha by which we judge matcha. Grain size should be very fine, with very little graininess in your mouth; it should have a balanced level of umami, without too much astringency.
Flavor - 12/20
Umami: 6/10 (10 being the richest umami)
Lack of Astringency: 6/10 (10 being least astringent)
Ingredients: Green tea.
Grinding date: June 2019
Packaging: Silver plastic bag inside resealable bag.
Region: Cultivated and ground in Kyoto, Japan.
Storage: We recommend storing one 30-gram bag at room temperature for daily use in the screw top can or resealable bag, and the remaining in your freezer for long-term storage if you buy more than one at once. NOTE: For freezer storage, double-seal in a plastic ziplock bag and tupperware container for maximum freshness and to avoid other food smells from affecting the matcha. Always allow the bag to sit for 24-hours before unsealing to acclimate to room temperature. This avoids condensation from damaging the matcha powder.
How much does 30 grams of matcha make?
It depends on how thick you make your matcha and how much you make, but if you use 1 gram (about 1/3 teaspoon) to make a 100 ml cup, that's 30 cups of matcha!
Did you know matcha is best when it's freshly ground?
How good your matcha is depends of course on the quality of the underlying leaf. However, producers buy many different production lots from many different farmers. Their skill, the reason why we call them master blenders, is in blending the leaves prior to grinding to create a specific profile in terms of powder color, powder aroma, grain size, matcha color, and most importantly the flavor of the matcha.
While the harvest season can make a big difference in quality since larger autumn leaves will be more bitter and more difficult to grind into fine powder, the harvest year is not necessarily important particularly right after the spring harvest (May - August). At this time, leaves may actually be too fresh to make good matcha--their flavor may create matcha that is very strong in umami but also too bitter. Meanwhile, leaves that have aged over the past year will be more mellow and perfect for balancing the fresh leaf.
Matcha however does get old quickly after grinding. In 6 months after grinding the color will fade, and the aroma will disappear. After 9 months, the strength of the flavor will also fade. As a result, higher grade matcha tends to have a best by date of 3-6 months, while lower grade matcha has a best by date of 12 months in Japan. Western brands often have a 18-24 month shelf life though.
As a rule, we do our best to ensure that the Yunomi branded matcha is never older the 6 months from grinding, and that matcha other brands are never older than 6 months from procurement.
