What will expired sencha japanese tea do to you?
// October 7th, 2009 // Bachelor's guide to cooking without Shan
fate stared me in the face. will a strange, poisonous fungus that has a taste only for sencha lead to horrific internal injury?
back in 2007, (and this, is so far back that back then doing LBO analysis was still in vogue..sheesh) i bought this here packet of unspecified japanese loose leaf sencha (its obviously not sencha, im not sure what i was thinking) tea from those kind folk over at Harrods of London. Now most would
say

that it was safe to conclude that by now it had expired. Most but not all. Today i set out on a journey of scienfic enquiery – to determine, if indeed 3 year sencha is
a) lethal
b) good
c) both of the above
attached are photographs from the epic brewing.
I did all my own stunts. The only precaution i did take was that i used boiling water today unlike my usual tea brews at c. 80c.
oh, and it turned out, well just about OK. i feelt let down by the sheer normalcy of the tea (though perhaps a trifle weak)

Hello,
I was wondering the same thing about some YamaMotoYama Sen-cha green tea that has a “best used by” date stamp of 25th of July 2007. It was opened but I kept it tightly sealed (rolled and clipped) in the original plastic packaging. I opened it today and the smell was strong and normal. I will use your method of hot boiling water and see if I get the same results.
Thank you for your post.

haha, im not sure if is should be encouraging such behaviour, and why i have so much expired tea, but:
ive since also had some expired YamaMoto matcha and i think i’ve survived (mostly) intact.
what doesnt kill you, makes you stronger eh.
