The very thin skin of the Pedro Ximénez variety favors the fast dehydration of the berries during the asoleo (sundrying) process, which makes it ideal for the production of raisiny sweet wines. The Montilla-Moriles region (especially in Montalbán, Montemayor, and Puente Genil) concentrates today virtually all the production of sweet PX musts that will later be aged in the different Andalusian winemaking areas.
