My bottle is actually Batch 18 and I have to say its now opened for 10 months now and bottle is just below 1/2 full. I'm disapointed witth this bottle and batch as so many reviewers rave about this but my bottle and batch has alchohol burn of a very young whiskey even watered down to 86% Whisky is also faily light showing poor cask quality especially since the staement of ex sherry. I hope Springbank corrects this issue and stop selling inferior whicky on their older quality offereings of the same 12 year. I also have the 15 and its dark and very delicious!
