The only one I've ever had honestly tasted like a odd mix of grass and soya sauce. I'll admit I've only tried it once and it was from a free pret promotion in Leeds but it was absolutely foul and thrown away after a couple of sips. Maybe basing my opinion on this is wrong but I just can't get myself to try it again.
Matcha seems everywhere at the moment and my teenage nieces love it.
I know each to their own and everybody has different tastes but I'd be interested to know why it's so popular?
I follow a dance YouTuber who seems to have about four a day and includes matcha powder in everything.
What other 'trends' confuses people?
