While I'll always be an Oolong and Pu erh guy at heart, I'm really enjoying experiencing lots of different teas.
First off Wesli DID advise me to just order direct from Den's. That they keep their stuff refrigerated before shipping and it's well worth the $3 shipping. Ok Wes you told me so!
Well, I had to go to Uwajimaya today to return something my son bought (and which fell apart) so I was compelled to see what selection of Den's they had. Ultimately a pretty small one.
I did pick up a Fukamushi Sencha:

I brought it home. Brewed it up. Realized something didn't add up. The tea wasn't much like Wes described. I picked up the package and flipped it over:

That's right. Feb 2007!!!!!

Needless to say I'm heading back out to Uwajimaya to bring this tea back. Pretty scary that they'd have a tea that expired a FULL year ago.
I also emailed Den's. They bill themselves at the Freshest Green Tea in the USA, I'm sure they'll be mortified to see that Uwajimaya is selling their teas a year past expiration.
I'll probably just go ahead an place an order with O-Cha.com and give their Sencha a try while I wait to hear back from Den's.
