Saca of March 2015, 15% alc, Rey Fernando de Castilla, Jerez de la Frontera. This particularly rare, single-cask bottling was drawn from one of the solitary butts of Pedro Ximénez Viejísimo at Rey Fernando de Castilla, that the Equipo Navazos immediately fell in love with when they first tasted it. It is therefore a one-off offering and extremely limited. While its average age is hard to determine, Navazos' conservative estimate places it to be “well above forty years” (Gutiérrez's note below puts it considerably higher). This is a brilliant wine, both deep, powerful and luscious but at the same time savoury, complex and remarkable vibrant and fresh. From a barrel that was always marked “Bota NO” at the bodega—which means “do not touch this, as it's too special”, this is indeed something remarkable. For PX fans, this is manna from heaven.
