I received my Greenhouse Superfoods Cerimonial Matcha in exchange for my unbiased opinion. Ceremony matcha is higher quality than culinary matcha. It’s not so bitter and is higher in L-Theanine than culinary grade matcha. Culinary grade matcha is made higher quality for drinking. Culinary is more for baking and cooking with rather than enjoying it as a nice cup of tea. This culinary grade Matcha powder is higher quality than some others I tried which were culinary grade. It is ground very fine and is more fragrant. It blends very well and I had no issues with clumping. Worth every bit of its cost.
