Here's a few luscious green teas I'd like to add to my tea cupboard...
Organic Misty Green 'A' from SanTion House of Tea... I tried a sample size of this recently and it's delicious. Very savoury and vegetal though... not for the faint-hearted.
Uji Matcha Kiku Mukashi, from O-Cha... sounds like it would be a pretty good beginner's matcha.
And Organic Kabusecha, also fom O-Cha... partially shade-grown so it has characteristics of sencha and of gyokuro apparently, which sounds interesting!
