We love advent calendars because they give us something to look forward to. A little treat every day. Secret Spirits make the best scotch whisky advent calendars. Each calendar includes 25 unique whiskies (one more than most other calendars), in 50ml minis (the biggest pour we've seen in an advent calendar). These cask strength whiskies, and a few blends too sensational to pass-up, are exclusive to Secret Spirits and are top quality. The Secret Spirits team, husband and wife Jonathan and Cindy, travel to Scotland every year to personally select each barrel of scotch that goes into their calendars.
