Founded in 1892, The Balvenie was one of the first distilleries to introduce various wood finishes to its malts. Their aptly named DoubleWood is a 12-year-old single malt that spends most of its life in second-fill bourbon barrels prior to being transferred to first-fill Oloroso sherry casks. There are three levels of flavor in this single malt. The original Balvenie imparts heather, honey and clean barley flavors. The bourbon barrel adds vanilla and a sort of cookie-like taste, as well as marshmallow, caramel and toast. The Oloroso sherry cask's influence is expressed via peach, marzipan, clover, a bit of honey and prunes.
