Good Sherry is the best value, but most underrated fine wine in the world. The Manzanilla from Fernando de Castilla is the best straight Manzanilla we've tasted to date, chalky, refined and stunning. If you think that one is superb - and it is - you should treat yourself to a half of the Manzanilla Pasada Pastora from Barbardillo which is Manzanilla starting to lean towards the Amontillado style. For a rare treat, Fernando de Castilla's Antique Oloroso is about as good as Oloroso gets, concentrated, ancient and mouthfilling. For decent, simple, commercial sherries, Delgado Zuleta's Fino, Amontillado and Cream are hard to beat. Delgado Zuleta are based in Sanlucar where a lighter style prevails. Their Amontillados are fresher than those from Jerez as they are based on old Manzanilla soleras. The Tio Pepe En Rama is as good a Fino as you'll find and the Vina AB is an Amontillado that still has half a foot in its fino origins, retaining that yeasty character that sets it apart from others.
