Balvenie announced the release of the David Charles Stewart Compendium of whiskies. Five chapters, each with five single cask selections from five decades honouring David’s 50 years in the whisky business. That’s a total of 25 whiskies, and they’re priced at over £125,000 for the set. Individual bottles range from £400 to £19,000. At these prices, the question to ask is, what is the whisky worth?
