Oh! Need to make my two recos here.
Lupicia consistently makes nice teas. Treat yourself at least once to
Lupicia's Yame Province (Hoshino Village) Gyokuro Shincha. Special area makes the best of this variety and special tea. So this is a growing method and an appellation-thing.
Only the very top leaves are picked on a certain day and they build a shade canopy over the leaves so that they are protected from getting astringent flavors. Amazingly round, buttery tea liquor...without the super-vegetal green tea "just mowed the lawn and dumped the grass" thing.
There is a special preparation (reduced temperature, long duration, barely any water) that I tried to the letter but did not like as much as just prepping it the way I would do any regular green tea. You can see videos of them making the canopies and instructions on making Gyokuro the "right" way if you are interested. Plenty online.
My other recommendation is Drunken Princess Oolong Tea from Mountain View Tea Village. Info is in the attached pic. More of a floral, lighter oolong. For those who like jasmine teas, I think you would dig this oolong.
