Sherry is a fortified wine made in a small region in south-west Spain. With a definition like that, ‘what is a sherry cask?’ should be a simple question to answer.

Unfortunately, as is often the way, it’s more complicated than that.

Fortunately, Diego Borrás works with sherry and whisky makers to source casks and pair them with whiskies, and knows how it all comes together. He and cask-obsessive Billy Abbott will lead us on a tasting journey pulling apart how sherry casks are made and how they affect the flavour of their contents, and dispelling the myths that still surround them.
