Great quality and value!
Flavor Name: Superior Blend, Size: 3.5 Ounce (Pack of 1), Flavor Name: Superior Blend, Size: 3.5 Ounce (Pack of 1)
After my Japan trip last year, I became a Matcha lover. Bought a few different brands, Naoki is the best and is my favorite. Taste fresh, smooth and love the bright green color. I drink Matcha latte everyday. Also whenever my friends come over, I would make one for them to show off my Matcha making skills. They love it as much as I do.

Good Beginner Matcha
Flavor Name: Superior Blend, Size: 1.75 Ounce (Pack of 1), Flavor Name: Superior Blend, Size: 1.75 Ounce (Pack of 1)
I am a beginner Matcha enthusiast and I love i making matcha lattes at home (my favorite is Strawberry Matcha lattes). I have repurchased Superior Ceremonial 3× now. I am on my second 3.5 oz bag. I've also tried another well known popular affordable matcha (Jade Leaf) and I immediately decided it is better to splurge accouple more dollars in purchasing Naoki. The texture of the powder is extremely fine. The color is a beautiful dark vibrant green. The flavor is very light with a very low bitterness and a hint of sweetness on its own. It has a very clean taste. However, the flavor does get easily over shadowed by milk and sweetners in a latte. If you want to taste the matcha better you need to add more matcha powder (~4.5 grams). Considering the fact that I am not drinking Matcha traditionally, I do not need a flavor profile that is super complex like what other matcha enthusiasts rave about (often times their recs are super overpriced for its size and/or hard to get). I just need something that will be paired well when used with milk and sweetners. I look for matcha with good quality, affordability, and easy accessibility to repurchase (via Prime adds extra brownie points). Superior Ceremonial checks all the boxes to a first good intro to matcha!

absolute favorite!
Flavor Name: Superior Blend, Size: 3.5 Ounce (Pack of 1)
I’ve been using Naoki Matcha Superior Ceremonial Blend for about two months now, and I absolutely love it. It has a very smooth taste with no bitterness at all, and it whisks into the most beautiful silky microfoam. The flavor is mild with a nice subtle umami taste, which makes it really enjoyable to drink every day. My favorite way to make it is as a strawberry matcha latte—it tastes just like something you’d get at a coffee shop. If you’re looking for a high-quality ceremonial matcha that tastes smooth and not too strong, I highly recommend this one. I will definitely be buying it again!

Delicious at the right temperature
Flavor Name: Superior Blend, Size: 3.5 Ounce (Pack of 1)
160 degrees Fahrenheit is the perfect temperature to reduce bitterness in this matcha. 170 and 175 produced more bitterness. It’s smooth, savory, not bitter, mixes easily, and is delicious purely on its own (not in a latte). It’s a great value for drinking alone and probably on the more expensive end if you sweeten or add milk.

Not bad
Flavor Name: Superior Blend, Size: 1.4 Ounce (Pack of 1)
Great if you like a more subtle flavor, not bitter. If you just add it to milk then it has a slight very brief strong aftertaste, but I like mine a bit stronger. it mixed well it did not clump for me, it was a great vivid color. I will say I prefer a strong, bold matcha taste in my lattes so I do not think I would purchase again but overall it is a great option for beginners, people trying to figure out what they like, or folks who like a smoother, not bitter taste. The tin did come dented unfortunately, not a huge deal but also not great to receive a product that has been somewhat damaged.
