When it comes to selecting the ideal size of Macallan 12 Double Cask, a professional approach can ensure a satisfying choice. First and foremost, consider the purpose of your purchase. Are you looking to savor this exceptional whisky on special occasions or as a regular treat? If it's the former, a standard 750ml bottle might suffice. However, if you plan to enjoy it frequently, opting for a larger bottle, such as a 1-liter or 1.75-liter, can provide better value in the long run.
