Sherry is a fortified wine from the area around Jerez, Spain. Made primarily from the Palomino grape, Sherry is one of the great expressions of the blender's art. In the Sherry Bodegas, fractional blending systems called Soleras, ensure a style of wine uniform from vintage to vintage. In the best of these, space is left in the barrels for a yeast called “flor” to develop and thrive. Sherries run from completely dry, light “finos” to nutty “amontillado” to rich “oloroso.” Because of the fortification and the exposure to air, Sherry is essentially oxidized already! An open bottle of Sherry will last almost indefinitely.
