My go-to teas are from Steven Smith. At $11 for 15 bags its expensive but the flavors are way above other teas at the grocery store. They're local to PDX too.
Their Fez green tea has a touch of spearamint in it that is just amazing. Their peppermint tastes fresher than most others and the Meadow chamomile is extremely floral.
(they're all good iced too)
