Contrary to popular belief, scotch whisky is best not served with ice. Ice will shut down the flavour, instead a few drops of room temperature water will open out the flavour of the whisky. Add too much and you drown the whisky! This small jug can be used to hold water for adding 'just a drop' to bring out the full flavour of your whisky. Inspired by a water droplet, this would also look nice sitting on a shelf in any home.
The large hole on the side is to fill the jug, if this hole is covered with your thumb when pouring, it also helps control the water flow for maximum control of the amount of water you add! It can also be shaken to add a single drop at a time! See here: http://youtu.be/qunUe4n-XG0
