Disclaimer: Kavalan is an admirable young distillery. I've tried a number of their whiskies but probably the only ones that I have liked are their solist sherry casks. I don't like cask experiments in my whisky in general, so this tasting probably doesn't bode well.
There is a good amount of sweetness topped off with a healthy dose of burnt caramel. If I didn't know better, I may say this was a pretty damn good bourbon. However, there is a balance and denseness in the nose that usually don't exist in modern bourbons. Of course, once you know there is Brandy here, you go, ah ha, I knew it!!
Yea, the brandy here makes things a bit interesting. Not all good, by the way. Many off-flavors in fact, but they may have been intended. Of course, brandy doesn't need to be only grape, nor is it just French cognac vs armagnac. It could be distilled spirit from any fruit and from any number of countries. I do detect some bitter grape skin and sweet citrus notes. Also acetone, somewhat astringent, a bit dry. Yea, not the greatest thing in the world. I am a biased purist though, so once I know this was a brandy cask, my whole tasting was a bit clouded. I do wish this was a 3cl instead of a 5cl mini so I can move on to my next dram. Yikes.
Short finish, just like many brandy. Things just die off after the palate.
