Glenfarclas 105 Highland Single Malt Scotch Whisky was initially developed in 1968 by George S. Grant, who decided to bottle a barrel of Glenfarclas Whisky at cask strength as a Christmas gift for family and friends. Today, the whisky represents one of the most classic and elegant Glenfarclas labels, and continues to be bottled at cask strength. It has a deep, golden color, along with an aroma of apples, pears and dark coffee. With a touch of water, the aroma fades into notes of rich spices, oak and sherry on the palate, and leads to a long, smooth finish with a lingering smoky flavor.

Glenfarclas 105 was rated one of the Top 5 Single Malt Scotches by Wine Enthusiast, which gave it a score of 95 points and said that it had an "almost bourbon-like beauty.
