Excellent matcha powder
Flavor Name: Ceremonial Grade, Size: 1.4 oz (40g)
The color is a vibrant, electric green right out of the tin, which let me know immediately that it’s actually a high-quality first harvest. It whisks up into a beautiful, silky froth with absolutely zero bitterness or chalky aftertaste. I’ve been drinking it straight with just hot water every morning, and it gives me a smooth, clean energy boost without the usual coffee jitters. Honestly, for a certified ceremonial grade, the quality you get for the price makes this an absolute staple in my kitchen now.

Great matcha powder for latte
Flavor Name: Ceremonial Grade, Size: 3.5 oz (100g), Flavor Name: Ceremonial Grade, Size: 3.5 oz (100g)
Beyond my expectations. This matcha powder is seriously impressive ,super smooth texture, rich and authentic matcha flavor, and such a beautiful vibrant green color. You can really taste the quality in every sip. It blends perfectly whether for lattes, baking, or just traditional matcha. Especially perfect for making matcha lattes , creamy, fragrant, and full of matcha flavor without tasting bitter. Definitely one of the best matcha powders I’ve tried lately.

Pure, fresh, and high-quality matcha
Flavor Name: Ceremonial Grade, Size: 1.4 oz (40g)
I really enjoyed this ceremonial-grade matcha. One of the things I liked most is that it comes in a jar, which helps keep it fresh and makes it easy to store. The flavor is very natural and well-balanced. It is not sweet, which I personally prefer because it allows you to enjoy the authentic taste of matcha and use it in different recipes without altering its original flavor profile. I also love that matcha is the only ingredient. It’s a simple, pure product with no unnecessary additives, which gives me confidence in its quality. The color is vibrant, it mixes well, and it provides an experience very close to traditional matcha. Overall, it’s an excellent choice for anyone looking for authentic, high-quality matcha.

Amazing Matcha Powder<3
Flavor Name: Ceremonial Grade, Size: 3.5 oz (100g), Flavor Name: Ceremonial Grade, Size: 3.5 oz (100g)
Probably one of the best matcha powders I’ve tried off of Amazon. It had all the notes, umami, nuttiness, matcha flavor, natural sweeteners and a hint of bitterness. When I first opened the packaged it has a strong and good smelling matcha smell. It’s a super vibrant green and looks very creamy even as just a powder. There was no clumps visible and mixed with water super smoothly. The texture of the powder was on point. There was no weird gooeyness going on. Onto my second 100g bag now. Definitely my go to matcha powder now, will be buying as long as it is available.

Sweet & nutty😍
Flavor Name: Ceremonial Grade, Size: 1.4 oz (40g), Flavor Name: Ceremonial Grade, Size: 1.4 oz (40g)
I actually like it I’m new to matcha so I’m starting with cheaper ones first I definitely recommend this! It’s so much different than the other ones I’ve gotten, it’s super sweet you literally don’t need any sweetener to it it tastes really good it’s nutty and buttery with sweetness I only rated it a 4 because I lowkey like my matcha bitter ish but I know many of you like it sweet it’s really green it’s a nice color the quality overall is great it’s smoothness and all its worth the money so definitely buy it! (I used Starbucks ice in the pic I didn’t purchase that obviously 😍)
