It’s hard to say exactly when it started this year, but a wave of “Shin-matcha” has been sweeping across social media. Products claiming to be the “best matcha of the year” are everywhere, often promoted with the idea that as long as it’s “new,” it must be the best.
However, “Shin-matcha” does not necessarily mean “the best.” Rather, it is better understood as a seasonal expression of flavor. If you prefer a fresher aroma and a lighter, more refreshing taste profile, then Shin-matcha can be an excellent choice.
Shin-matcha: Refers to matcha made from tea leaves harvested during the new tea season (around April to May) and processed immediately. Tea producers often compete to release their products as early as possible, resulting in the characteristic freshness of Shin-matcha (while also tending to bring out a slightly more astringent edge).
This flavor profile is inherently time-sensitive— most of these products are sold within one to two months after harvest, making them essentially a seasonal, limited offering.
That said, the quality of matcha has never been determined solely by how “new” it is.
Producers rely on their own blending techniques (ブレンド) to create a consistent and well-balanced flavor profile. This is precisely why many standard, year-round offerings are able to maintain a stable taste—by skillfully incorporating tea leaves from different harvest periods or years.
Under proper storage conditions, such teas should not be simply regarded as “not fresh,” nor are they evaluated in the same way as age-defined products like alcoholic beverages.
Another point that is less often discussed: beyond being used for “Shin-matcha,” tencha (the raw material for matcha) is not always ground immediately after harvest. Instead, it is often allowed to mature for a period of time.
Through this maturation, the flavor tends to become rounder, with greater depth, a fuller body, and more concentrated aroma.
This is why— many high-quality single-cultivar matcha, and even competition-grade matcha, are sometimes released only in autumn, or even into winter.
“Shin-matcha” has its own distinct and appealing flavor direction, but it is by no means the only standard by which matcha should be judged.
