Chris asked:
Why do some people turn a new bottle of Scotch Whiskey upside down before opening?

Charlie Says:

Dear Chris,

I have not come across this. In the old days, experienced drinkers would shake the bottle vigorously and judge the 'beading' - the foam which gathers in the neck. This gave an indication of alcoholic strength and 'texture': 'the heavier the beading, the better the whisky', was the rule of thumb.

Helpful?
