Me here too been longing to find matcha green tea
Thank God,
I was able to find one in Save More (Parkmall), Matcha Latte Milk Tea by Soya. The packaging contains ten sticks which costs you 140php I guess (I forgot the price). Anyway, the taste was so so. I somewhat didn't like the taste. It's way too different from the powder that Starbucks or The Coffee Bean has been using. I usually consume two sticks in a cup but still I'm looking for that distinct taste. The color is not that bright.
I saw another matcha green tea in Ayala (Metro Supermarket) but haven't tried it yet. It will cost you about 20php more, maybe because it says that it is genuine from Japan. Whenever I can drop by, i'll see and share the verdict afterwards.
From Healthy Options (Ayala), it's a bit pricey though but the packaging is nice. I haven't seen the powder itself 'coz it's fully sealed. Hope, it's as green as leaves. They say that if it has this vibrant color green then it is authentic. I wish it would be that greenish to give justice to the price. Hehehehe!
