This Balvenie Tun 1401 is one of a series that provide variations combinations of older and newer aged casks. The Batch 6 is a bottling comprised of whisky from seven bourbon and two sherry casks. The bottling actually specifies the barrels from which the batch was created. It does not have an age specification, and the ages of the barrels used to create the batch are not specified, but are said to include casks from across a number of decades.
The nose is delicate, with bourbon, fruit notes and a hint of aged-sherry. It coats the palate, a slight oily feel, with a mix of sweet (orange, toffee) emerging to spicy (pepper). The finish is medium to long, dry with the pepper/spice lingering.
This is a most interesting and delightful single malt. It is a smoother, more subdued dram than I expected given the mix of bourbon and sherry casks. It also has a complex mix of youth and age that brings a special quality, something that I have found in other single malts as well.
