The flavor of bourbon changes with the addition of water. Some experts say that even if you intend to drink bourbon neat you should a few drips of water. Some say it must be served on ice. This glass allows the whole experince to happen.
This glass is designed to have a small amount of water added to the bottom of the glass. Then to be placed in the freezer until the water freezes in the small area at the bottom. Remove the glass from the freezer and add bourbon. The bourbon will start out neat and as the solid ice begins to melt the flavor of the bourbon will change. I have tested this it works very well.
I am now working on caddy design for 2 and 4 glasses so storing them in the freezer is easier.
