Peter Sisseck “PSI” Ribera del Duero 2023

93 points Robert Parker
93-94 point. Tasted just before bottling, so a sample of the final blend, the 2023 PSI is juicy, ripe and approachable. It is a little showier and headier, despite having similar alcohol to the bottled 2022 (perhaps a tad higher, but not quite reaching 14%), and it feels a little riper, with peachy notes and some decayed flowers. It has abundant tannins and feels like it's in need of some more time in bottle. This is usually the case for PSI: the tannins need time. They are resolved quite quickly, but it does need a bit of time.

Peter Sisseck sources this sizeable blend of Tempranillo and 10% Garnacha from 700 plots, mostly in the eastern part of the denominación de origen, working with 200 growers, two co-operatives and 90 hectares of his own grapes. Fresh, zesty and energetic, this is all about fruit intensity and minerality rather than wood, with a waft of mountain herbs, raspberry, plum and redcurrant flavours and fine-boned tannins

92 points Vinous
92-94 point The 2023 PSI brings together fruit from 12 villages, mostly Gumiel de Mercado and Villatuelda in the Soria sector of Ribera del Duero. The project began in 2007 with the recovery of neglected vineyards, now totaling 200 hectares across about 700 parcels, 25% of which are estate-owned. Garnet colored, it opens with pine and herbal notes, then red fruit-cherry and a touch of plum. The palate shows fine-grained tannins, a midweight texture and detailed fruit. The bottle will reveal the Soria character in the interplay of fine tannins and acidity.
