Makes the Best Cold Matcha Drinks
Flavor Name: Original, Size: 17.6 oz (Pack of 1), Flavor Name: Original, Size: 17.6 oz (Pack of 1)
I got the barista matcha latte because I heard it blends well in cold drinks. I made a lavender cream matcha with it more than once now & each one was so delicious. I liked it better than Starbucks Iced Lavender Cream Matcha and not as sweet as theirs imo. I plan to try making more drinks with it in the future when I purchase it again.

Good matcha and way cheaper than Starbucks and taste the same
Flavor Name: Original, Size: 5.3 oz (Pack of 1)
This matcha tastes pretty good and has a nice, smooth flavor. Unlike some matcha products, it doesn’t have an overly grassy or bitter taste. Instead, it tastes more like a matcha latte, making it enjoyable and easy to drink. It is definitely on the sweeter side, and you can tell that sweeteners have been added. Personally, I’m not a huge fan of the extra sweetness, but that’s more of a preference than a quality issue. Overall, it still tastes like real matcha and makes for a pleasant drink. If you enjoy sweeter matcha lattes, you’ll probably like this product. While I would have preferred a less sweet version, I still found it enjoyable overall.

Delicious and convenient matcha latte
Flavor Name: Original, Size: 5.3 oz (Pack of 1)
This Jade Leaf Matcha latte mix is absolutely delicious and so convenient to use. The organic Japanese matcha has a smooth, authentic flavor that's lightly sweet without being overpowering. It mixes easily with hot water or milk to create a perfect latte every time. I love getting the health benefits of matcha in such a tasty and easy-to-prepare form. This has become my go-to morning drink instead of coffee.

Good taste!
Flavor Name: Original, Size: 5.3 oz (Pack of 1), Flavor Name: Original, Size: 5.3 oz (Pack of 1)
I love matcha for the health benefits! This has the taste that goes along with it. Yes it has sugar in it, but I’m fine with that. I don’t drink it every single day and I also mix with another organic one to cut the sugars in half. I like that it’s barista friendly and this brand doesn’t make my stomach hurt, as some have back in the beginning when I first tried matcha. It gives me the energy and focus I need without the crash.
