The classification of whisky cups
The glass was round-barrel, short. The characteristic is that the bottom of the cup is very thick. This is because of the need to add ice to drink whiskey. Three or four pieces of ice in the inside sloshing, not a certain thickness is not.
So the whisky is much thicker than the Brandy Cup. The sound of the ice in the glass is so wonderful that if everyone drinks whiskey on one occasion, the sound is a symphony of wine.
