Sous Vide Limoncello

<…In the car, listening to america’s test kitchen podcast…>Wait…I can make my own limoncello?
Phew! Christmas list solved. I’ll look up the recipe when I get home.

<…At home, searching the web…>
Darn…it has to rest for weeks, if not months. Christmas is too close. Hmm.

<…adjusting search terms…>
Aha! Sous Vide to the rescue! I can speed the infusion time up from weeks to hours. Next, I need 190 proof grain alcohol.

<…remembering a particular party in college…shudders. Moving on…>
Darn, again…I can’t buy Everclear 190 in Ohio without a prescription. It’s 127 miles to Pittsburgh. I’ve got a full tank of gas, ten organic lemons, it’s snowing…

<…one bootlegging run to Pennsylvania later…> 
Excellent warning labels on this bottle: “Caution! Extremely Flammable! Contents may ignite or explode.” That’s what you get with 95% alcohol.

I got to work scrubbing and zesting lemons. And…that’s it. Lemon zest, Everclear, a quart mason jar, and three hours sous vide yield lemon infused liquor; simmering water and sugar gives me simple syrup, and the two combine into limoncello. I can’t believe it is this easy.

Recipe: Sous Vide Limoncello

Adapted from and Sous Vide Supreme Easy Limoncello

Prep Time: 10 minutes
Cook Time: 3 hours
Makes 2375ml (2.5 quarts)



190 proof

  • Zest from 10 lemons (preferably organic, because they usually aren’t coated in wax to protect them.)
  • 750ml bottle of 190 proof grain alcohol (Everclear 190)
  • 4.5 cups water
  • 4.5 cups sugar


1. Zest the lemons

Scrub the lemons. (If they’re non-organic lemons, scrub hard to remove their protective wax coat). Zest the lemons, avoiding the bitter white pith. Put the lemon zest in the canning jar. (Wrap the lemons in plastic wrap and refrigerate for later use.) Pour the alcohol into the canning jar and screw on the lid.

2. Sous Vide infuse the alcohol

Put the canning jar in the sous vide unit. Add water to come up to the lid of the jar. (Don’t submerge the jar, or it will float around.) Sous vide at 135°F/57°C for 3 hours. Strain the alcohol through a fine mesh strainer, then again through a paper coffee filter to remove all the lemon zest from the alcohol.

3. Make the simple syrup

When the alcohol is almost done infusing: Put the water in a large pot over high heat, and bring to a boil. Stir in the sugar, and keep stirring until the sugar dissolves. Remove the pot from the heat and let it rest until the infused alcohol is ready.

4. Combine, rest, and serve

Mix the alcohol and simple syrup, then divide into jars or bottles and store in the freezer. You can drink it right away, but it is better if you let it mellow for a week before drinking. Limoncello keeps for about a year…if it lasts that long.


What if I don’t have a sous vide?

So, you want to do it the old fashioned way? Easy. Everything is the same, except step 3 becomes “let the jar of alcohol and zest age for at least 3 weeks, up to 45 days”.

What if I can’t find 190 proof grain alcohol?

I found out that I can probably get Everclear 190 in Ohio, if I find a liquor store that is willing to accept a signed affidavit that I’m using it to make cordials, and not chug it straight from the bottle. (Frankly, with all the warning labels, I felt like I should be wearing goggles and gloves when I was handling the liquor.)

Or, I can step down to Everclear 151, which is the second best option, and legally available in Ohio. (Maybe next time, instead of driving for three hours. The things I do for this blog…). The main reason to go for higher alcohol content is because alcohol is better at extracting lemon flavors; the more alcohol, the more flavor extraction.

It’s easy to substitute a lower alcohol liquor; you want something with no taste, like grain alcohol or vodka. We want 60 proof limoncello – 30% alcohol. I didn’t know that proof is twice the alcohol percentage…until now.

Here is the amount of syrup you want to add to a 750ml bottle of alcohol, depending on the proof. (I went over the math on this multiple times, and double checked against this calculator on so I’m pretty sure I got it right.)

  • 190 proof grain alcohol => 1625ml syrup => 1083ml (4.5 cups) each sugar and water
  • 151 proof grain alcohol => 1135.5ml syrup => 757ml (3.25 cups) each sugar and water
  • 100 proof vodka => 500ml syrup => 333ml (1.5 cups) each sugar and water
  • 80 proof vodka => 250ml syrup => 167ml (3/4 cup) each sugar and water

This is the other reason to go for higher alcohol content is the amount of sugar you can add. As you can see, we can add a lot more simple syrup to 190 proof grain alcohol than we can to 40 proof vodka – the 190 proof batch is much sweeter. (There’s also a lot more of it – you get more limoncello for your liquor dollar. That said, my bottle of Everclear cost $17, so it’s not a huge expense.)

Another aside: Simple syrup is equal parts sugar and water by volume…but sugar is less dense than water, so when it dissolves, we only get half the volume in liquid.

Hi! I’m Mike Vrobel. I’m a dad and an enthusiastic home cook; an indie cookbook author and food blogger with a day job, a patient spouse, and three kids who would rather have hamburgers for dinner.


  1. NicoNelko says

    I added 0.8% citric acid (3g powder for each 375 bottle) which I think made it more “lemony”. (also used mix of meyer, organic lemons and valencias instead of just lemons)

  2. Just came across this, as a note you CAN buy the real 190 proof Everclear in Ohio. Print out a nicely typed note that you will be using the Everclear to clean your wine making equipment with a food grade alcohol. Sign it and date it. I found that Giant Eagle here in Columbus of all places had the 190 proof and sold it to me with that note without a hitch. It was under $20 too.

  3. Shawnna Short says

    I’m guessing using the sous vide won’t evaporate the alcohol, correct?

  4. Lauren says

    Hmmm. Can you do this sous vide method in the instant pot? Just wondering! thanks. I am new to EPC but a total convert, as you can tell, given that I’m willing to try it in the IP. I use it for oatmeal in the morning to soup at lunch to whatever at dinner and of course cheesecake for dessert, so why not give it a go? thanks.


  5. I made a half batch of this yesterday and it came out great. Only 151 proof is available in CA, but it still has a similar warning label. Heat isn’t required to make the simple syrup because even room temperature water can dissolve a lot of sugar. I just put the water and sugar in a jar about an hour ahead of time and shook it a few times.

  6. wow!,how fun! I
    have made limoncello but didn’t know all the proof info.Thank you
