However, a phrase on oxygen. The machine primarily pumps pure air (79 p.c nitrogen, 20 p.c oxygen) into the espresso somewhat than fuss with nitro cartridges. That is cool, however oxygen publicity is the recognized enemy of fresh-tasting espresso. After the nitro evaporated, side-by-side style assessments did present extra flabby oxidation flavors within the nitro than the fundamental non-nitro.
However contemporary off the machine, this does not present up a lot. What you discover is bracing, enjoyable bubbles that additionally add perceived sweetness. These bubbles cowl numerous sins, constructing a dense head atop chilly brew that appears for all of the world like a well-poured Irish stout.
A WIRED editor, a photograph of Cumulus’ plentiful nitro, jovially suspected chicanery. “I’d swear they used Guinness for the promo photographs,” he wrote.

A robust hat tip to cocktail advisor and educator Josh Seaburg, of Virginia’s Model Citizen Cocktails, for a very good espresso martini recipe to do that stuff out on. For the file, this concerned 1.5 ounces of vodka, 0.75 ounces of espresso liqueur akin to Mr. Black, and a half-ounce of easy syrup, blended with an oz of chilly espresso. Combine, shake, pour. The machine makes solely double photographs, so one capsule offers sufficient chilly espresso for 2 cocktails.
Who’s the Cumulus For?
On the one hand, the Cumulus is a formidable piece of engineering—one which succeeds on a number of fronts the place different machine makers have failed.
However it isn’t a tool for espresso snobs. It lends itself greatest to those that prize the comfort of a Keurig and are not overly fussy, or those that’d naturally load up their chilly brew with milk and sugar or different flavors. Cumulus doubles down on this with flavored syrups starting from Orange Piloncillo to Cinnamon Demerara.
