The Whisky Water Pipette allows controlled dilution of spirits.
A water dropper gets used in the whisky tasting process, after initial nosing and tasting. The addition of water will release other aromas in the whisky. Use room temperature water where possible to not disrupt the whisky too much.
Dip the tip of the glass pipette in to your water and press your finger over the hole in the bulb to hold the water in the tube. When you release your finger from the hole the water will get released. Adjust the pressure of your finger on the hole to control the amount of water you add to your whisky.
