Glad you found at least one that appealed more to your tastes, Mike
I've run through all the teas at this point. I noticed something different with these teas -- perhaps it was from running cooler temperatures throughout -- but the latter brews (usually 4 and 5) often did not have a lot of flavor, but I was still able to get a nice 'flavor' from the aroma... and they rode well on the steeps that came before and the astringency that usually slowly built throughout.
I also noticed -- again perhaps because not going to boiling at the end -- that none of them hit that "hair" smell. I don't recall anybody ever describing it as such, but to me, sometimes a late-sencha starts to smell like hair. It's not too pleasant, if you know the aroma or quality I'm describing. Maybe I'm the only one who has that mental connection.
And... I was wondering, I noticed a few of the teas had not fully opened by the time I poured the first steep. Is that normal for sencha? I haven't really paid attention to that before, and I wasn't sure if I should wait to pour until it's all opened, maybe.
Looking back, I think I liked #2 the most so far. Nothing really stood out as outstanding on this first round; usually I have a "WOW!" comment somewhere, but not this time. But I did find most of them enjoyable and none of them were bad. I think for my second pass through the teas, I will try starting little hotter.
Time to "reveal the numbers" for myself and see what's what!
