What a fun idea from Redbreast. For the tasting experience of Redbreast Sherry Finish Lustau Edition, the distillery sent out three bottles: A bottle of classic Redbreast 12 Years Old, a bottle of the new sherry-finished Redbreast Lustau, and a bottle of actual Lustau Oloroso Don Nuno sherry. In this way one can follow the creation of Redbreast Lustau pretty much from start to finish.
Redbreast Lustau is a permanent addition to the Redbreast line. Though it is officially a NAS release, it includes single pot still whiskey that is aged in both bourbon and sherry casks for 9 to 12 years. It is then finished in an Oloroso sherry butt from Bodegas Lustau which was crafted from Spanish oak, where it sits for an additional 12 months.
Now Redbreast has a long history with sherry casks; the 12 year old is aged in a variety of cask types (including both bourbon and multiple types of sherry casks). The finishing is a new spin — as is, of course, the loss of an age statement.
Tasting reveals a dramatic departure from the 12 year old expression, as Redbreast Lustau takes that classic, malty pot still character and gives it a serious spin. The nose is only slightly off from the expected, showing a stronger and more pungent orange peel note plus a nose-tickling pepper note to back up the malt, nougat, and toasty grains. On the palate is where things really start to diverge, the sherry giving the whiskey an intense nuttiness, along with notes of raisins and figs, again backing up that bold, malty body. The finish is lengthy, creamy, and spicy — all at once — everything building to a cohesive whole that is well worth exploring, age statement or no.
As for the actual sherry sample included here, well, I have no idea how people drink this stuff.
