1. Make sure the CoolShot is completely dry before filling with your favorite liquor. The presence of water can damage the crystal and/or prevent removal of the top.

2. Fill the glass with vodka, gin, tequila or other liquor to the fill-line and place in freezer.

3. A standard residential freezer can provide the recommended storage temperature of 0 - 15F (-17 to -23C). Do not store at temperatures less than -20F (-28C), where vodka begins to freeze.

4. Do not immerse in hot water while freezer cold. This can result in damage to the crystal.

Add a drop of Vermouth for taste. Do not attempt to freeze juices or water along with your vodka. Check back soon for more sub-zero innovations!
