So, I think this may be the same product as listed and reviewed by others 7–8 yr ago at:

This was the expected wiry strands of large, intact black tea leaves of the famous hybrid variety grown in Nantou County, Taiwan. BUT mine were not labeled as “highest quality” nor as an oolong. Maybe it has to do with the production year? Mine was the Summer 2020 harvest, and I bought it 3 yr ago, so the BTTC description might have been different then as well, but I didn’t think to capture it back then.
I steeped 2.5 g in 4 oz alpine spring water at 90°C for 2 min, 4 times in succession. Great malty aroma, flavors of malt, brown sugar, mineral and assamic heritage that nicely complemented my breakfast of Lucky Charms cereal (oat puffs with marshmallow bits). Not bitter or astringent, and not as pleasing as other TRES #18 teas I’ve had, but still very good. I finished off the leaves with additional steepings with boiling water, to get another two cups of good tea.
Flavors: Brown Sugar, Malt, Mineral, Raisins, Tea
