A worthy trio of whiskies for the Whisky Show 2018, and each of them really does represent their era. The Ben Nevis is of an old-school style, while the Ledaig stands for one of the better modern day whisky the industry has to offer presently. A single grain as the future? Coul very well be. This Invergordon is certainly one of the better iterations I've had the pleasure of tasting.
We've seen a flurry of Invergordon 1972 hit the market in recent months. All of these casks come from the stables of Whiskybroker. This particular one needs a lot of time, but does reward your patience.
If you're looking to taste really old whisky for a (relatively) low price, than grain whiskies provide a solution. This Invergordon 1972/2016 was bottled by WhiskyNerds, a small Dutch independent bottler.
