High quality Matcha
Flavor Name: Ceremonial Barista, Size: 1.06 oz, Flavor Name: Ceremonial Barista, Size: 1.06 oz
Edit: I tried this matcha twice now, and it’s perfect! No lumps, excellent taste, froths well! Everything you could imagine. I used one teaspoon, and 20 oz of water heated to 160°F, sifted the teaspoon of matcha into a matcha bowl, used my bamboo whisk, and poured over milk with a bit of agave nectar. I’m very pleased with the results. This is fine matcha! ///
This appears great and high quality, I haven’t tried it but will do a side by side to see how well it froths compared to the matcha I have on hand.
I will come back with further information, so far it smells and looks wonderful.

The best Matcha please don’t skip this review.
I don’t often write reviews. In fact, I hate writing reviews. It’s probably the worst thing. But let me tell you this Matcha is probably the best Matcha that I’ve ever tasted and have purchased on Amazon. I tried other matches and don’t give me wrong. They are all somewhat all right, especially if someone that doesn’t know what the hell they’re doing, but this Matcha so good and I mean so good this Matcha is so good. I feel like I would pay for a sponsorship from them, I would even sponsor them. I know this doesn’t make sense, but it makes sense to me thank you crafti you are by far the best tasting the most glorious, and in fact the most rewarding Matcha experience I’ve ever had it’s to the point you make me want to buy tickets to Japan so I can get Matcha in person. Sincerely your probably not number one fan but number one enjoyer the T-Rex.

Great tasting matcha
Flavor Name: Ceremonial Barista, Size: 1.06 oz
Crafti Classic Ceremonial Grade Matcha Powder is hands down one of the best matcha powders I’ve tried. The flavor is robust without being overpowering, with a subtle hint of citrus and a smooth finish. I would definitely recommend it to anyone looking for a high-quality matcha
