A Whisky Macdonald more commonly known under the shortened name Whisky Mac is a cocktail made up of whisky and ginger wine. The whisky is expected to be a Scotch Whisky, usually a blended type. The ginger wine should be green ginger wine. Recipes vary from those having equal parts of each ingredient to those that use a ratio of 3 to 2 of whisky to wine.
A common recipe is to take 1½ fluid ounces Scotch whisky, 1½ fluid ounces green ginger wine.[1] Pour both of the ingredients into a wine goblet with no ice. A hot version can also be made, akin to a hot toddy, made with the addition of boiling water.
The invention of it, and its name, is attributed to a Colonel Macdonald, who devised it during the days of the British Raj in India.[2]
