Toro Albalá reserve select lots of their best vintage wines for later release. These rich and complex Pedro Ximénez wines are destined for 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 (through controlled exposure to oxygen) which brings a kind of nutty, iodine character that infinitely complexes the sweet, fruit cakey wine but also gives it added freshness. Naturally, as the wines concentrate in flavour and texture, the colour darkens and the mouth-feel thickens. Vintages are selected for release after a minimum of 20 years in barrel and only when they have attained these classic hallmarks of aged PX.
