I've been trying different vattings, generally because the taste of the bourbons I'm buying recently do not appeal 100%. Exceptions: a rich almost custardy Knob Creek, and the Old Gran-dad 86 proof I got at Randy's recently, which has that indefinable orange marmalade taste I liked in the ND versions. These will stay as they are.
And so to vatting.
While initially I liked on its own VSOF 12 years old, as it sat in the bottle either it changed or I noticed things that IMO could be improved. The taste is good but the body was thinnish and the finish a little lacking. I did 3:1 this bourbon to Woodford Reserve. Generally, you add older bourbon to a larger amount of younger; here I did the reverse because it worked. The woody sappy oily WR filled out the VSOF 12, lengthened the finish and deepened the taste while retaining the malty and cherry-like notes of the latter. It's got the best of both and the oily accents of the WR, deriving I believe from its pot still element, are brought down a notch or two.
And then I took that very smooth, sweet but a little corny Corner's Creek (current release, not the 8 year old version of years past), and added it to Maker's Mark, 3:1 Maker's to the other. What happens is the Makers gets deeper in taste, fuller and with a more integrated finish. It may sound odd that this can happen by adding a whiskey that may well be younger, but it can. I'd estimate the Corner Creek at 4 years old, maybe less, the label does not state it is straight bourbon.
And so, I get the flavor that appeals to me.
