Cocktails are a very personal thing. Everyone takes their favorite tipple a little differently, and whether it be an extra dash of bitters, an olive garnish versus a lemon, each mix is catered to their own taste.

But no matter how you might take your cocktails, we can all agree that they should always be ice-cold (with very few exceptions). There’s nothing worse than taking a sip of your cocktail, only to find it’s room temperature and pretty aggressive (it is just warm booze, after all). A sidecar carafe perched in a bowl of ice could save you from this, but we prefer a more efficient method of keeping things frosty.

These Cooler Than Cool Martini Glasses are our secret weapon for an ice-cold cocktail every time. These double-walled cups are filled with a proprietary gel that, when frozen, keeps your cocktails at optimal drinking temperature for hours. Plus, their BPA-free plastic construction means they’re great for bringing anywhere broken glass could be problematic, and the silicone band makes them comfortable to hold, so you don’t have to worry about freezing your hands off.

Best Cold Martini Glass

Just put them in your freezer around lunchtime, and after just a few hours chilling, you’ll be set for an extra chilly Martini happy hour. They were designed with convenience in mind, so you can store them in your freezer without worrying about them breaking over time due to temperature-induced expansion and contraction.

Don’t just take our word for it. According to one reviewer, “I like a very cold martini, and the Frozen Martini glass did the trick. It kept the martini very cold until the drink was finished.”

Now is the perfect time to take advantage of those End of the Year sales, so grab a glass while you still can and never drink a lukewarm cocktail again!
