Toro Albalá reserve select lots of their best vintage wines for the Gran Reserva label. These unusually rich Pedro Ximénez wines are destined for a very long aging in oak barrels. After filling and sealing, these barrels are left for decades in their single-vintage state. It's during this slow maturation that the wines undertake their delicious, savoury, rancio transformation (though controlled exposure to oxygen) which brings a kind of nutty, iodine character that infinitely complexes the wine but also gives it added freshness. Naturally, as the wines concentrate in flavour and texture, the colour darkens and mouth-feel develops accordingly. After a minimum of 25 years in barrel, vintages are selected for release only when they have attained these classic hallmarks of aged P.X.
