How To Rapidly Flavor any Booze Using Whip-Its

Infusing liquor is the secret to a lot of great cocktails. You can add rosemary to rum. You can add beef to rye whiskey. The possibilities are endless, but one thing is constant. It takes a long time. Days—even weeks—sealed in a jar.


But there’s a trick used by infusion masters. It takes mere minutes, and the flavor profile comes out almost exactly the same as a full infusion. The device is so effective, they call it “the time machine.” Here’s how nitrous oxide makes it happen.[jump]

It’s Friday afternoon, you’ve made it through the long week, and it’s time for Happy Hour, Gizmodo’s weekly booze column. A cocktail shaker full of innovation, science, and alcohol. I think this rum would pair nicely with some nitrous oxide.


We went to Amor y Amargo in NYC and tapped our favorite barman, Sother Teague, for a crash course in crash infusions. The results were delicious and incredibly fast.

The secret is the iSi Cream Whipper. As the name suggests, it’s for making fresh whipped cream. You simply pour in the cream, pop in an N2O charger, release the nitrous oxide gas into the cream, and presto, you’ve got whipped cream. Infusing booze works almost exactly the same way.


  • 1. Pour your booze into the reservoir.
  • 2. Add in your flavoring agents. Then screw the top down to seal it.
  • 3. Screw in the N2O charger until the gas releases into the bottle. Let it stand for one minute.
  • 4. Replace the N2O charger with another one, pressurize, and then shake it for one minute.
  • 5. Using two glasses to catch the spray, slowly release the pressure using the iSi’s trigger (see video). Reserve the liquid.
  • 6. Unscrew the iSi, and pour the liquid through a strainer into an awaiting vessel.

What was perfectly clear rum, after a basil and orange peel infuser, became a cloudy yellow. It also got incredibly delicious. I could have poured it over ice and sipped it. However, mixed in a daiquiri, infused rum took on a new dimension. I generally find daiquiris too sugary and boring. But the basil cut the sweetness and added depth and complexity. It was terrific.

It kind of looks like what’s happening in your Soda Stream, right? I know what you’re thinking, and don’t try it. Soda carbonators use CO2, not N2O and there are a couple of important differences. For starters, as Sother explains, you can get much more pressure into the bottle with N2O. That pressure forces the alcohol into the cell walls of the flavoring agents. When the bottle is then depressurized, the alcohol rushes back out again, and it carries those flavors with it—that’s what you normally wait for weeks to happen using maceration.


The other reason to use N2O is that it adds less flavor than CO2. CO2 puts a little bit of carbonic acid to the mix, which is why sparkling water cocktails taste a little bit sour. You don’t want that muddying up an infusion.

Once you get your hands on an infusing tool, you can experiment like crazy. The iSi cream whippers range between $50 and $100, so it’s a pretty accessible way to alter a cocktail. Add dark chocolate to bourbon? Sure. Hot chilis to vodka? It burns—but why not?


In fact, this is the same method used by major producers of bitters when they’re trying out new flavors. It’s a huge saver of time and money. When Bittermens made us some custom coffee bitters for The Angry Ginger, they used the iSi, and they turned out great.


Once you’ve found ratios you like, then you can move on to bigger batches, letting them slowly soak to bring out the full flavor. Or you can just keep on experimenting forever, once glass at a time. The world is your infused oyster.
