That’s a great question, and I hate to say I don’t know. But I don’t. Ardbeg keeps this information private, but the Corryvreckan can still stand up against those aged 10-12 years with no problem. Given the information they’ve released about other whiskies in the Ultimate Range collection, we can assume that the Corryvrecken has been aged for at least that long, but there’s no sure way to tell.
