Spiritfilled are an Independent Bottler, Whisky Cask Investment Specialist. We offer expert help in purchasing, storing, bottling and selling casks of premium Scotch whisky. You don’t just buy one bottle with a label. You get a cask full of whisky while its ageing. One cask might yield between 200 and 300 bottles. And, because the cask improves a whisky’s taste over time, the longer it’s in the cask, the more valuable it becomes.
