So this past year I have really been exploring scotch and learning about what flavors I like. I know a little water unlocks flavors and is recommended by many scotch connoisseurs. I purchased a tovolo ice tray that makes giant ice cubes to reduce surface area and chill my scotch without excessively watering it down.
I found soap stone "ice" cubes that cool with out watering the scotch down. Upon further investigation I found cubes made of ceramic, granite, stainless steel, soap stone and marble.
What is your thoughts on these and what do you recommend?
