PSI is the 23rd letter in the Greek alphabet and is the name of Peter Sisseck’s (of the coveted Pingus and Flor de Pingus) utopian wine from Ribera del Duero. Peter has sought out the best independent vineyard growers in Ribera and is incentivizing them to improve viticultural practices and shun chemicals, lower yields and practice biodynamics by paying them increasingly for the fruit as they improve. The result is a “give back” to the region wine that also expresses the “soul” of Ribera.

A rich red with chocolate, ripe fruit, walnuts and spice. Full-bodied and round with ripe tannins and a flavorful finish. Plenty of ripe fruit at the intense finish and lots of old-vine character with bark and wet-earth undertones. Real deal. Drink or hold.

I had already tasted the unbottled 2018 PSI, which saw a jump in quality after they got a new winery where they had much better working conditions. This wine is produced with purchased grapes from 200 hectares in around 750 plots and 20 different villages throughout Ribera del Duero (they now rent and work 50 hectares of these vineyards themselves). In 2018, they were able to use some 12% Garnacha and 2% other grapes, including whites that are found intermixed with the Tinta del País/Tempranillo in the old vineyards. Garnacha adds freshness, and the wine shows it—the character of the grape comes through in the blend. It fermented with indigenous yeasts and matured mostly in 5,000-liter and 10,000-liter oak vats, but 20% of the volume aged in used French barriques for 18 months.
