This vinegar begins with the sought-after Pedro Ximénez grape, which is known across Andalusia for it’s complex depth of flavor and use in single-varietal sherries.
Sherry wine is combined with a generations-old vinegar mother vinegar and then put through a traditional solera barrel-aging process for 10 years. The nuttiness that you taste in sherry comes from the exposure to air during the aging process. Natural yeasts form on the surface of the wine (called flor), which eat the sugars and impart a toasty, sometimes slightly savory nutty note.
