An Affinity is a slight variation of the Perfect Manhattan that requires Scotch as the whiskey of choice. It makes a great before dinner drink. Just as in the gin Martini, this cocktail will take on a completely different character depending on which Scotch you use.
Pour the ingredients into a mixing glass with ice cubes.
How Strong Is the Affinity Cocktail?
Let's make the math very easy and assume that we pour an 80-proof whisky and two 30% ABV vermouths into our Affinity Cocktail. In this example, the drink's alcohol content is about 25% ABV (50 proof).
This number should not be surprising as most cocktails that we categorize in the 'martini' family are very strong and often range between 20 and 30% ABV. That is because they are almost always made entirely of alcohol and the only element that brings them down is water from the ice.
