Sencha products make up more than 70% of all Japanese teas on the market. People drink Sencha more than any other product in Japan. And the taste and flavor changes by production area and the season of the harvest. The tea leaf shape is like a needle. Sencha products are rich in catechins and vitamin C. And the earlier the harvest season, the more amino acids are preserved. Also, various levels of steaming are involved in the manufacturing process of these products. The most common is standard steam. However, medium steamed is growing more popular, and more products can be found on the market nowadays. Deep steamed Sencha has a smaller particle size, so please brew for a much shorter time.
