    Pretty good, recommend
    Size: 16 Ounce (Pack of 1), Size: 16 Ounce (Pack of 1)
    These are some photos and this Morton salt for size comparison. It’s pretty big. It has a spoon inside which is pretty useful. Ok so I really like this matcha. Its culinary grade and it tastes pretty good. I use it for my daily matcha latte. Its not bitter and actually slightly sweet-ish, but it has no additives so its nice. It does get a little clumpy when I stir it, I wish I had a matcha whisk, I just use a spoon.

    Worth the money
    Size: 16 Ounce (Pack of 1)
    I'm inexperienced with matcha... Just wanted to order some good matcha, only to discover all of these obscure classifications and prices varrying wildly. Before this brand, I ordered ceremonial and also "culinary cafe" from the jade brand. Couldn't really taste a significant difference, so I didn't sweat purchasing this. There is a difference with this: the higher quality matchas did foam more when mixing and had slightly thicker consistency, and tasted a bit less grassy. This brand actually tastes fantastic, if you don't mind a very subtle grassy but sweet flavor. The savory sweet flavor dominates in a good way; grassy is very much still nothing more than an afterthought. But - and a very significant but - it hardly foams after mixing. So, the viscosity of the liquid when mixed, although enjoyable, leaves something to be desired. That said, like a good salesman the seller points out that this mathca is unusual because of its concentration on being organic, even at the expense of whatever desirable flavor profile could be contributed by pesticides, lead, radiation etc. Perhaps this is an exaggeration... Nevertheless I take comfort in their emphasis on safety anyway. It's definitely more affordable, being around $1 an ounce. Thanks for keeping other matcha brands honest... So I recommend the value absolutely. But it you want the best of the best, I just don't know enough to give you a good answer.

    Micro Ingredients Organic Matcha makes a good anytime tea.
    Size: 32 Ounce (Pack of 1)
    Micro Ingredients Organic Matcha Green Tea Powder delivers exactly what it promises: a clean, earthy, first-harvest matcha that balances approachability with authenticity. It’s a versatile and surprisingly smooth everyday matcha. The flavor leans toward earthy, grassy, and mildly nutty, with a gentle bitterness that feels natural rather than harsh.

    Great. Just as good as fancy stuff But dose not pair with peppermint.
    Size: 16 Ounce (Pack of 1)
    If you're making Macha lattes or mixing the match with anything, this is perfect! No need to buy the expensive ceremonial level stuff unless you're drinking ONLY Macha. This is honestly perfect for everything. Mix 2 of its provided spoonfuls with 1/2 cup of kettle hot water and stir, maybe even add more matcha until a bit thick, pour over a glass full of ice (should fill half the glass if full of ice) as the last half as milk with a pump of your favorite syrup. Mine is strawberry, my gf's is Vanilla. Peppermint was not good, though fyi.

    Makes It Green; Doesn't Taste as Clean
    Size: 16 Ounce (Pack of 1)
    It is matcha. It makes things green. For all intents and purposes, this is enough for the typical matcha user. For those with a bit of an upturned nose to anything that's "inferior" to matcha, then this is not for you. By taste, this product is not as good on the tastebuds as, say, Jade Leaf. It doesn't do matcha justice and, in my opinion, does not mix that well when making lattes. In terms of color, this one is also paling in comparison when by itself, but when added to other things as a flavoring agent or colorant, then it does the job as well as it can. I am not saying this matcha is bad at all. I think if it comes down to drinking, save your money and get some Jade Leaf or equivalent ceremonial grade matcha. You WILL taste the difference. Now if you're going to be making a lot of baked goods or cooked goods? This wouldn't be that bad—you don't want an overbearing matcha taste anyway and the shade of green this produces is not THAT bad.
