Ice has been a hot — er, cool? — item on trend watchers’ lists for some time now, and it all comes down to choosing the right cube (or chunk, or spear, or sphere) for the task. Variety is the ice of (eau de) vie, it would seem:
While it’s anticipated that Grant Achatz’s forthcoming Chicago bar Aviary will be the forerunner in ice cube culture with 14 shapes and varieties available come opening, Forty Four at The Royalton comes pretty close. This sleek, midtown Manhattan lounge features about five different ice offerings nightly.
What’s the big deal about solid water, you ask? According to Serious Eats’ Cocktail 101 column, good ice is at the chilly heart of a great cocktail:
Not only does it chill a drink, but it also releases water into the cocktail, binding the ingredients, smoothing out the flavor, and taking the edge off the base spirit.
Today, many craft-cocktail bartenders are getting fancy with ice. In some bars, giant blocks of ice are chiseled and carved into large chunks, tall cylinders (for highballs), spheres, and cubes. In the hands of a deft bartender, ice becomes an element of showmanship.
(The article goes on to note the hidden advantages that plain ol’ tray-to-tastebuds ice cubes may have over fancier ‘cuts’ for home use, so if you’re not a bar pro, don’t worry that you’re missing out.)
Still, those who charge large for their bar menu offerings would do well to consider the cube. In With ice, size matters, The Wall Street Journal’s Food & Drink section echoes the importance of the right ice:
When it comes to ice, size does matter, not to mention shape, density and clarity. If you prefer your Scotch on the rocks, beware: small, brittle ice will quickly dilute years of cask aging. No one wants a Bruichladdich slushie.
But large cubes or spheres of ice will melt more slowly, bringing your drink closer to the temperature of the ice without over-diluting it. Larger pieces, such as spears the length of a glass, are ideal for keeping tall, carbonated beverages chilled. And there’s a place for pebbled and crushed ice, too: mint juleps, swizzles and many tiki drinks wouldn’t be possible without them.
… and goes a step further, offering how-to tips on creating the perfect spears, spheres, cubes, blocks and crushed ice.
Taking the most scientific approach is The Globe and Mail in its article, Do large ice cubes yield a less-water cocktail?
The Globe challenged a specialist in low-temperature physics at the University of British Columbia to prove — or debunk — the theory that larger cubes shed less liquid. I won’t spoil the results — you’ll have to read the article to find out if you should opt for cubes or ‘bergs in your customer’s preferred potent potable — but the investigating scientist’s conclusion is telling: “Real-world physics problems often are surprisingly subtle and complicated, and this is a spectacular example of that.”
