The crisp, refreshing Verdejo-based wines of Spain’s Rueda region are gaining recognition in the U.S.just in time to be a featured summer white. The 2015 Silga, from Bodegas Alvarez Diez, has a classic floral and citrus nose leading into more fresh citrus that lingers in a very long, balanced finish. No oak, no problem. And the wine’s screwtop and fanciful label makes clear this Rueda is ready for fun and adventure.
