Many thanks to Wymm tea for a sample!
The dry tea was somewhat glossy and dark, and the smell was fairly neutral — leather and earth, which is something I think is pretty common to shou teas. Once I rinsed it, it smelled like shoes, leather, dirt, and loam, with perhaps a bit of camphor. It reminded me of a root cellar, actually.
The brewed tea was dark. Like really rich, homemade beef broth. It had a slightly fishy, earthy, mushroom-y smell, and I was worried I should have rinsed it twice, but oh well — down the hatch it goes! The first steep tasted uninspiring and muddy, but the second steep developed a menthol/camphor note. That note developed and reminded me also wood, branches, autumn leaves, and cedar. And, oh yeah, this shit was dark. Almost like Guinness beer!
As I drank the third steep I noticed a cottony, gauzy feeling on my tongue. The fourth steep introduced mineral notes, but the initial fishiness was still there. Steeps 5 and 6 were fairly similar, though at the 6th steep I bumped the steep time up to 10 seconds. I noticed that as the steeps progressed, it tasted less of loam/earth and more of wood/cedar. By steep 7, my body became really heavy. I think I stopped after the 7th steep because I was so sleepy!
