Tasting Notes

About:

Mash bill of 100 percent barley, copper pot still, aged minimum three years; 92 proof; aged in new American oak.
Appearance:
A roasted yam, with a coat of henna.
Nose:
Pleasant, yet slightly chlorine-ish when I first opened the taster. But once in the glass, it settles into more of a mellow marshmallow along with cooked blackberry.
Palate:
I like this more than I thought I would, given it’s all barley. I tend not to favor single malts; their nuances tend to be lost on me, honestly. I thought it would be more grain-forward, but this is sweeter and softer than I had been anticipating. A pleasant surprise. I also get a creative tinge of orange and spice, like in mulled wine. And yet when I go in for yet another sip, it changes into more of that slightly dirty and grassy aspect I don’t love about single malt. And then it makes my upper lip start to tingle. Darn. I was hoping for a different reaction.
Finish:
Comments:
I’m intrigued that it’s a shape-shifter, but it leaves me a little cold, despite the burn. (If I could rate a 2.75, I would.)
