I. The Vinho Verde DOC (appellation) is Portugal's largest wine region.
II. Due to cramped vineyard space and regular rain, VV vines are traditionally co-planted with other crops, and trained above ground on granite pergolas.
III. With the exception of Alvarhino/Albarino-based (fairly rare) Vinho Verde, these wines may not exceed 11.5% ABV.
IV. There is actually such a thing as red Vinho Verde. This isn't typically exported. Red VV is also quite acidic and low in alcohol.
V. Vinho Verde's signature petillance is actually the result of CO2-spritz before bottling.
Bonus question: Although VV is typically drunk without any aging, shouldn't its Xtra-hi acidity enable this wine to be age-worthy?
A VV to try: Quinta do Ameal 'Loureiro' Vinho Verde 2005 (~$12) - Imported by European Cellars. This wine, from the VV sub-region of Lima, is made from the Loureiro grape variety. Q. do Ameal is a bit more kraftig than most V. Verde. It is also a vintage bottling, whereas other VV's are NV offerings. While this wine is rather acidic, it feels rather smooth and viscous in the mouth. In addition to the expected mineral flavors, Quinta do Ameal slides in some ripe red pear flavor. Give it a try with a side of potato salad and be happy.
