I have heard of a double...but my wife took a bottle of wine to our neighbors for "girl talk" and I wanted some scotch...I measure all my scotch out so I dont drink so I dont go through a bottle to quick and it occurred to me I drank a double double or quadruple....can I order that in a restaurant? BTW...macallan 12 year...not as good as the 18 much more smokey and more bite...I had it neat...is was either that or oban...but Im low on oban.
