El Candado is Spanish for the padlock, and indeed every bottle comes with a small padlock and two little keys. The idea is that a butt from this solera used to be locked away as someone from the Valdespino family wanted to keep the wine to himself.
As with most PX, it is very sweet and unctuous, but not over the top. The palate shows toffee notes, dessert with figs and honey & guava. It grows slightly darker towards the end, showing hints of rich coffee, caramel and a light spicy edge (pepper, cardamom). Long finish.
