"Coat the inside of the glass by turning it on its side 6 times (a wine glass is good to view the whisky). As whisky is quite oily you really want to coat the inside. Then hold the glass up to the light and see what happens to the top rim of the coating. You should start to see ‘tears’ develop and as the move down the will grow into ‘legs’.
The younger the whisky the faster and closer together the legs will run down. An older whisky the tears will be bigger and run more slowly. Also the older the whisky the further apart the legs are."

"Swirl the whisky around the glass, coating its sides thoroughly. Then wait and watch, as the liquid runs back down the side of the glass, the 'legs' of the whisky.

If the 'legs' are thin and run quickly, then it may be a younger or lighter whisky. If the 'legs' are slow and thick, then it may be a heavier or older whisky. "
