A few words about this item from chef José Andrés:

If you are looking for something unique, this is it! Spain is the only place in the world where true Sherry wine can be produced. And that means it's the only place to find this amazing Sherry vinegar! The giant oak barrels used to store this vinegar give it a fantastic golden amber color. Lightly acidic and dry, you can taste delicious hints of vanilla and dried wood. A great addition to your favorite stew, over a fresh salad, or in homemade gazpacho - this is one unforgettable vinegar!
