The smoothness makes the 105 drinkable at cask strength, but add a little water to fully explore it's great depth.
In 1968 George S Grant decided to bottle a cask of Glenfarclas at natural strength as a Christmas gift for family and friends. The strength of that single cask was 105 British Proof- so Glenfarclas 105 was born. They still select some of the finest casks frin their warehouses and vat them together- without adding water- to give a constant strength of 60%. And today, Glenfarclas 105, the world's first commercially available cast strength whisky, is just as smooth as ever.
