To use this coffee set, first, take out one of the granite chilling stones from the set and place it in the freezer for a few hours. While the stone is chilling, brew your Bourbon Barrel Aged Coffee as you normally would. When the coffee is ready, take the chilled stone out and put it in your coffee cup. This will cool your coffee without diluting it. Remember not to use hot water on the granite stones directly as it may cause cracking. After use, simply wash the stones with mild soap and water, dry them thoroughly, and store them in a dry place. Enjoy your coffee and the unique experience this set offers!
