Once you taste matcha from Material Matcha Uji you’ll find it hard to drink any other matcha. The others are fine for smoothies and cooking leave MMU for drinking on it’s own. Anyway, MMU01, this is a weird place to start but I’m really enjoying the aftertaste. It’s sweet with a unique grassy umami. Kinda almost reminds me of the aftertaste in a ginseng oolong. It’s so good. It has a sharpness to it unlike the other two thanks to the higher intensity of grassy flavors. Still not grassy like a green tea though. Now that I’ve had all three I have to admit I’m surprised at how different, even though subtle, each can be. MMU03 is still my favorite but MMU01 is a very close second.
