But you have to go to South Korea to get ‘em
If you're a hardcore iced coffee aficionado, or just spend a lot of time on Pinterest, chances are good that you've heard about putting coffee ice cubes in your iced coffee to keep your beloved drink from getting watered down by regular old ice cubes. And though the technique is popular among home coffee fanatics—Martha Stewart among them—it's never really been implemented in cafes on a large scale (even though customers have been asking Starbucks to carry coffee ice cubes since 2008). But South Korean companies have figured out how to give the people what they really want, by bringing coffee ice cubes to stores. Both Dunkin' Donuts and Krispy Kreme serve coffee ice cubes in iced coffee beverages in their South Korean stores.
These so-called cube drinks aren't just served with frozen hunks of leftover coffee, though, and the brands have been getting creative with the cubes. At Korean Krispy Kreme, for example, you can get an Original Coffee Cube or a Latte Cube, which are regular drinks that happen to be served with coffee cubes. But there's also the Macchiato Cube, which comes with cubes of frozen milk that have been drizzled with caramel.
Dunkin' Donuts in South Korea has also been on their coffee ice cube game, offering the an iced caramel macchiato that comes with frozen coffee cubes, a regular macchiato with cubes of chocolate, and a so-called Choco Cube Milk, which seems to be chocolate cubes in chocolate milk. Dunkin' Donuts takes the craze one step further by offering up fruity drinks with complementary flavored iced cubes. The Red Orange Ade, for example, comes with citrus-flavored red cubes, while the Blue Lemonade comes with—you guessed it—blue ice cubes. As Dunkin' Donuts describes the drink on their site, "Lemon in the blue sea, the sea looked like lemonade."
Dunkin' Donuts and Krispy Kreme aren't the only places to find coffee cubes in South Korea, though. A quick search on Instagram for the Korean hashtag "커피큐브," or "coffee cube," reveals several independent cafes that are also upping their iced coffee drink game. For example, Dessert.39, which has stores across the country, has coffee and espresso ice cubes. So does dal.komm Coffee, another local chain.
Starbucks stores in South Korea, however, have yet to get in on the coffee ice cube game. But they do offer Fruit Jelly Yogurt Frappuccinos that come with cubes of jelly floating around the bottom, which are kind of like flavored ice cubes? Except not, I guess. And while these coffee ice cubes are getting trendier in South Korea, you're still out of luck if you're in United States, since they're not available at any of the aforementioned coffee chains here. Guess you'll just have to make coffee ice cubes yourself.
