One of the most popular distilleries in the world, over the last four decades Macallan has built probably the best reputation for quality malt whisky and is the most sought-after whisky for collectors. Rare expressions can change hands for thousands of pounds and prices for such bottles are continuously going up. Macallan built its enviable reputation by focusing on the fact that they mature their core range in 100% sherry oak barrels. This results in a rich whisky with a good depth of flavor. However in recent years, a new range of Macallans were launched: the Fine Oak expressions, which are matured in a mix of sherry and bourbon oak casks.
