Although there are disappointments in both Gyokuro and sencha, I have been quite pleased with the vast majority of both for quite some time.
I should have said, "As a starting point, I usually have to get close to 50 USD per 100 grams to get what I am looking for in a Gyokuro. Clearly there are better ones to be had at higher pricepoints ... but higher cost does not guarantee better gyokuro. A lot will also have to do with how "close to the source" a vendor is. But this does not guarantee success either, just increases the odds of getting a good "value" ... a gyokuro priced appropriately.
Are 50 USD gyokuro as mind blowing as ones costing 2X as much, likely not. But I bet there are disappointments at all price points.
