The word ‘sherry’ conjures up in the mind a menagerie of wrongs. It is usually thought of as a sickly sweet dessert wine that grandma drinks at Christmas; pouring a little dram out of the bottle of Harveys Bristol Cream that has been sitting there for years, the alcohol all evaporated off and with sugar crystals sticking the cap on. This is not the sherry that confronts the visitor in Spain.
