I have been asked the question by someone who needs to know if is is different from 40% ABV, 46% ABV and some at 52% ABV.
The majority of the caloric content of whisky comes from the alcohol itself. It has about 100 cal per 1 1/2 oz pour (~50 ml).
The only difference between cask strength (usually ~60%) and run of the mill 40% ABV is the addition of water to the whisky. Therefore the higher the ABV of a whisky, the proportionally higher the caloric content. I would think that you would have to be drinking a great deal of alcohol before you really had to worry about these differences. Also, when I'm drinking a couple pours of cask strength whisky, I tend to drink less volume.
