There may be nothing more satisfying than an ice-cold cocktail after a long day, but making a cocktail cold enough for a connoisseur's palate can be a tricky ask for bartender and party host alike. IceLiners could be the solution, making it possible to create icy-cold cocktails simply and stylishly.

IceLiners is the invention of former bartender Daniel Kana who, having spent years hearing patrons beg for truly cold cocktails, set about creating a specific tool for the job. The result is IceLiners, a silicone mold that, as the name suggests, lines a glass with a sheet of ice. After countless prototypes, Kana created the finished product for which he now has a patent pending.

Used in its simplest form IceLiners lets you enjoy a cold drink thanks to a sheet of frozen water lining your glass. However, the real fun begins when you swap water for a mixer or fruit juice. This lets you create odd combinations that offer something different in terms of look and taste. Whatever liquid you use to line your glass, the result is a drink which Kana claims will stay close to freezing temperature for 35-45 minutes.

The process is simple. You press the IceLiners silicone mold onto a glass, pour your chosen liquid through the hole, and then freeze in an upright position. The IceLiners molds are only guaranteed to work on the glasses supplied by Kana, but they can be fitted on other, similarly sized, glasses.

IceLiners is currently being funded through a Kickstarter campaign, with Kana seeking US$30,000 to manufacture the first production run. A pledge of $25 offers a reward of one IceLiners mold and one glass, either martini or rocks. While a pledge of $45 offers a reward of one of each mold and glass. If all goes to plan, the IceLiners will ship to backers in December. Availability is limited to those in the US.

I think that is a 'cool' idea. :)


Daniel, this may work fine for a glass with a stem, as the stem gives the server, drinker, somewhere to hold the glass other than the frosted upper surface.

But not user friendly for the scotch style glass, sure your server can put them on a tray, before removing the silicon mold, but the drinker would freeze there fingers, or worse yet let the drink slip out from the icy layer of frost that will build up on the outside of the glass.

Plus wouldn't your lips freeze upon contact with the leading edge of ice whilst sipping?

Have you thought of possibly reversing the split liner, and create an outer insulating skin. Keeps drink colder longer as well.

Never mind, I'm already working on my patent...

The article says that it will keep your drink frosty cold for 35-45 minutes. No way !!!!!!!! The lining of Frozen water or juice will warm up from the liquid poured into it and just be sitting in the warmer room or being held by warm hands. If it last longer than 5 minutes I will be surprised, and its melting will dilute the mix that is sitting in it.


As the founder of IceLiners I feel compelled to comment on this article.Over the past two years I have made thousands of these ice lined glasses for people ranging from the food and beverage director at the Four Seasons Hotel, to executives from Brown Forman( think Jack Daniels and Woodford Reserve) and for Libbey glassware. All of them seem to be quite impressed with this simple but effective process. When a vodka or gin martini is made with a shaker and ice, the cocktail pours out at about 24 degrees. This actually helps to keep the ice frozen as alcohol can get colder than 32 degrees. To preserve the ice even longer, glass is a great insulator and also helps to keep the ice frozen. When tested at room temperature, the ice does in fact last longer than 35-45 minutes. The IceLiners rocks glass is designed with a thicker layer of ice so that the alcohol can be poured in at room temperature and still have the ice outlast your drink. I took physics and chemistry classes back in college and believe me these glasses really do work. Due to overwhelming demand we are now shipping internationally.
