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.
