Pedro Ximenez grapes, also known as PX, are most commonly associated with the production of sweet Sherry wines. The grape variety is primarily grown in the Montilla-Moriles region of Spain, where it accounts for 70% of the vineyard area. PX grapes are sun-dried to concentrate their juices and create the raisined flavor profile characteristic of PX wines. These wines are known for their rich sweetness and flavors of toffee, figs, chocolate, and dried fruit. They are often made in a solera system of fractional blending, and aged in barrels to develop their complex flavors. PX wines are also produced in other countries, including Portugal, where it is known as Perrum and used in white blends.
