Wow, thanks sofia. i took your info and did a search at Calvert Woodley in Wash, DC and found it. Looks to be a great buy. This from CW:
NV Quinta da Aveleda Avelada Vinho Verde
what more can you expect for $6
This is a great white wine to serve when you have friends over who don't particulary like wine. It's got a little fizz to it, which is intentional as I understand it, and it's light and crisp. Dry, but with tart fruit flavors. And with a $6 price tag, it's about the best I've found in that price range. If you don't open it expecting too much then you might even be pleasantly surprised.
