The DōMatcha Ceremonial grade of Matcha is harvested in the spring at the first flush; only the brand new top leaves are chosen. These leaves render a very smooth but strong flavor, considered to be one of the top grades of Matcha. As a result, it commands a higher value in the marketplace. The Summer Harvest DōMatcha is harvested in August; the leaves for Summer Harvest have been on the tea plant longer and render a more astringent flavor. The price of Matcha reflects the quality of various grades of Matcha. If you are a purist or traditionalist and enjoy your Matcha with just hot water, then the Ceremonial will give you better tasting Matcha. If you are going to use your Matcha in a latte or a blended drink, then you may as well go for value and use the Summer Harvest.
