In a nutshell:
A full, rich and sweet cask strength Speyside single malt matured in ex-sherry casks.
Glenfarclas 105 is so named because when it was first released back in 1968 105 Proof was the measure of its alcoholic strength. That's 60% ABV in new money. It has all the classic flavours of Glenfarclas in one glass, a complex nose of oak, apples and pears, and a dark toffee sweetness. The dry and assertive palate has a rich spiciness, combined with a hint of oak and sherried fruit. And it all leads to a smooth, long and lingering finish. They recommend you add a drop of water to bring out the full range of flavours.
