I find that adding water was not delicious as adding milk. With milk I feel it brings out the matcha flavor more. This is contrary to what Ippodo has mentioned on their website. There is not too strong of a matcha flavor, it is pretty mild. I recommend for those who love a sweet matcha au lait. Needs to stir vigorously to dissolve, it is not easy to dissolve with cold liquid.
I adjust the amount of spoons to my drinks, depending on how sweet you like your drinks. 2 or 3 tablespoons is a bit much for me.
Overall, I am impressed with Uji-Shimizu and my matcha au lait was enjoyable, it is not too strong or too sweet so I could say it is very easy to drink and simple to prepare.
