The 2014 PSI is a blend of Tempranillo with 10% Garnacha and perhaps 1% of other grapes found interplanted with the other varieties in the old vineyards, mostly white Albillo. The idea here is to protect the old vineyards that are disappearing from Ribera del Duero and provide some added value to the grapes coming from them. They have identified a grand total of only 56 hectares of Garnacha in Ribera del Duero, and they have rented 20 of those to save them, because they were set to be uprooted. It has great freshness and energy, with an herbal/leafy touch in the nose that also adds complexity. It's a wine that seems to improve from vintage to vintage, and I believe the jump will be noticeable when they produce it in their own winery from the 2015 vintage onward. The Garnacha always has a lower pH than the Tempranillo, and helps to provide an extra spark of freshness. This is an approachable Ribera, but keeping the character of yesteryear. This is really what Ribera del Duero used to be: all old vineyards and no new oak whatsoever. Kudos to that!
