I've got a couple of "mystery teas" that I got from a friend--turns out she still prefers green tea! They're not well-labeled, but they're good...well,I think so. One is an Assam, the other is some kind of Chinese black tea. It's a bit peppery and cocoa-y, so my guess is that it's a Yunnan. Some of Adagio's teas look like they might fit the bill as replacements--I've got a cart full of likely candidates (and one or two other things just because! ).
What I want to know is: What's the best way to go about conducting the taste-test? One after the other? On separate occasions? Very small amounts of each or a cupful?
