To prepare this tasting note, I first poured a wee dram into a Glencairn glass neat. The color is a soft amber and the nose is slightly sweet and subtly oaky. I didn't pick up any fruitiness on the nose, but rather the mild sweetness was more like a toffee. The first sip gives a soft yet rich flavor suggesting bourbon barrel aging. A subtle sweetness remains on the tongue after the fluid heads down the hatch, followed by a nice, soft spice as the last lingering flavor.
The second, smaller pour entailed adding a few drops of water. The alcohol on the nose seemed to have released more quickly after a swirl, but the soft butterscotch/toffee aroma remained. The whisky really opened up and smoothed out from the few drops of water, mellowing the flavors only lightly while removing the alcohol's influence on the flavor on the tongue.
I would recommend tasting The Singleton of Glendullan 12 Years Old neat and then promptly adding a few drops of water to release the radicals and let this nice, very inexpensive whisky impress you as it did me. I see this as a nice, everyday, easy drinking whisky. I say inexpensive as I picked up the bottle I sampled for just under $30 on sale at Bayway in Elizabeth, NJ on my return home from a recent NYC visit in 11/2016.
