Whiskey stones – solid cubes made of either stone or stainless steel – offer the benefit of keeping your drink cold without diluting it. Many prefer to use them over ice cubes because they don’t melt, are odorless and tasteless, and have a more prolonged cooling effect. All this means the customer will be able to enjoy his or her drink in a whiskey glass without any alteration of taste or smell.
Nonetheless, excellent promo whiskey stones require equally nice packaging. No company would hand them over like ordinary rocks, for sure. Just look at the new packaging designs for promo whiskey cubes here above.
