Grapes are sourced from Fernando de Castilla's partners vineyards in the Jerez district. The soil type is Albariza. Picking takes place in early September. Fernando de Castilla deals only in prestigious, premium wines. The sherries are all from individual soleras. They are bottled without blending, cold stabilization or filtration of any kind in order to preserve the subtlety, purity and distinctive aromas of these premium wines. The products are all bottled in clear glass to show off the wonderful colour of the wines. Fernando de Castilla Antique Amontillado comes from a very old Fino (8 yrs old) which is refortified from 15.5% to 18.0% ABV and introduced into a solera of Amontillado where it spends a further 12 years.
