Just don’t expect this to be an ice replacement for sodas etc. Really only get these if you actually drink whiskey, and want the temperature SLIGHTLY chilled…or if you want to look cool.
Wait what? oh someone else… sorry, thing in my ear.
As for how well these work, I like them. bought them when they were available a few weeks back, and have used them a couple times. they’re the smaller of the 2 varieties they have, and I figure the larger ones probably hold cold longer, but the do a decent enough job of dropping the temperature of my scotch without overly diluting it like adding too much ice would.
I’ve gotta nice set of stones myself. Sent to me from England. These work well to cool it down, but not so well to heat it up. You have to keep swapping stones in and out to slowly heat it; which becomes a chore.
You can,they aren’t replacements for icecubes. . . I suggest using them in the liquids they’re advertised for. These stones need to sit in the freezer overnight before use and if you use them in anything with sugar they will leave gunky residue even after wash. I leave em soaking in water for a day after used with mix drinks.
