smooth and great quality matcha
Size: 1.4 Ounce (Pack of 1), Size: 1.4 Ounce (Pack of 1)
I was surprised by how fresh and vibrant this matcha is! The color is a beautiful bright green, and it blends really smoothly — no clumps at all. The flavor is rich but not very bitter, perfectly match with coconut water. I’ve been using it for lattes and coconut water, and it tastes amazing either way. You can really tell it’s high-quality matcha. Definitely will repurchase once I finish this bottle!

Great Matcha for Price! 🍵
Size: 1.4 Ounce (Pack of 1), Size: 1.4 Ounce (Pack of 1)
I was hesitant at first because the price seemed too good to be true, but this turned out to be amazing for the cost! It’s not the brightest “ceremonial first harvest” matcha I’ve tried, but it’s also not dull or too yellow tinted. The taste and aroma are both nice, and it works perfectly in lattes or on its own. It whisks up silky smooth. You get a great amount for the price too, some brands charge $20+ for a similar amount and quality. Overall, an amazing affordable find for matcha lovers!

Deceptive advertising - NOT 100 servings
Size: 1.4 Ounce (Pack of 1), Size: 1.4 Ounce (Pack of 1)
The bag shows 100 servings per container, which is one of the reasons I bought it, but it’s more like 30 servings. The bag shows serving size 1 scoop approximately 1g but the directions says “sift 1.5 tsp” but the scoop included in the bag is 1/2 tsp (it would take 3 scoops to equal 1.5 tsp). The taste is a little off, not as smooth as other brands I’ve tried.
