Abadia Retruerta — Winery in Sardón de Duero

A stunning winery on the edge of Ribera del Duero. Officially it isn't part of the appellation, but that has more to do with politics than with practice. The upside is that they can work far more experimentally here, with lots of different grape varieties. That makes a visit fun too, because you can taste all the wines side by side, and a tour of the vineyards explains the thinking behind that diversity. And we haven't even mentioned the (very luxurious) hotel and (Michelin-starred!) restaurants, housed in a magnificent old abbey (abadía). A must-visit if you're going to Ribera del Duero.
