Does anyone know about the preferred acidity for Sherry vinegar (Vinagre De Jerez)?
I recently bought a bottle of Napa Valley Naturals Sherry Reserve Vinegar from Whole Foods. This vinegar had an acidity level of 4%. When I got home I checked my old bottle of Don Bruno Sherry Vinegar and it has an acidity level of 8%. That is a big difference!
Several sites on the internet indicate that Sherry Vinegar must have a minimum acidity of 7%.
Are there any Spaniards out there to help me out?
