well its Macallan mate. She's like the Nike of single malts its very good stuff but I find the price hard to justify.
Its why in fact Macallan went down the path of introducing the fine oak range because production costs are lower using american oak barrels (bourbon) rather than sherry oak barrels, however even their 18yo was like $189 IIRC.
My thoughts are as follows:
Fine oak - cheaper than Sherry oak and is very fruity, makes your mouth water / dry and then releases beautiful flavors like vanilla, raisins and fudge
Sherry oak - very exy but my favorite but caramel galore. Could really go without that artificial coloring IMO but the tastes - at first its very spicy, but after you have drank a dram you get the following flavours, burnt cookie / creme caramel, spices like cardamin, orange peel and a hint of wooden smoke - truly amazing mate.
you can make your own recommendation but I think you know what to go for now.
