I don't even drink water with ice so am not likely to add it to bourbon.
I have been adding water, but found myself inconsistent until using a shotglass to measure. I am curious how you all add water to bourbon, say like tonite I a drinking the Weller Antique 107 and adding water. Is there a watering device to add water to straight whiskey? I don't put too much whiskey in the glass, so I need to control a very small amount of water.
