This is fantastic. It’s a special bottling of Gonzalez Byas’ Tio Pepe Fino Sherry, taken from the cask when the flor (the layer of yeast cells growing on the surface of the liquid) is at its thickest in Spain. It’s a thrillingly complex, slightly hazy Fino (it hasn’t been clarified or filtered) and it has amazing complexity and finesse. Tangy, nutty, mineral and quite spellbinding. You need to drink this ideally on the day of opening, or the day after, because it loses its incredible freshness quite rapidly in contact with air. A total bargain at £11.95 from The Wine Society.
