The set of Vina Whiskey Wine Chiller Stones comes in a set of nine. They include a nice pouch to put them inside before setting them inside the freezer. This keeps them clean and easy to find or use. I like these for my 8oz whiskey tumblers because regular ice waters the drinks down making them taste weak. These will chill the small amount of whiskey perfectly. They, however, will not turn a large/tall glass of warm beverage cold.
If you're using these for a tall cocktail I recommend that the ingredients are chilled from the refrigerator first and the stones would help keep it cold. Using these stones keep the drinks chilled and not watered down. Everyone who tried them liked them. When finished I wash and dry them then put them back in the pouch to freeze again. They can be used over and over.
I actually washed these in the dishwasher silverware tray with the heated dry on and it worked great to clean them to use again. When drinking a small drink of scotch or whiskey these are perfect to use. In a tall drink, I would use a straw because tipping the glass high to finish the drink might make the stones tumble down and hit your teeth. After all, these are stones. I actually made a tall cocktail with mostly refrigerated alcohol and juice served in a tall glass with a straw and these worked fine to keep it chilled for the duration it took to drink it.
These would make a great gift for a whiskey/scotch drinker. I'm very pleased with this product and know these will last for a very long time.
