Now this right here? This is what I call chillin’ with class. You haven’t lived until you’ve had a Hennessy slushie straight from the Ninja Slushi Machine. This one’s cold, smooth, and dangerously good, the kind of drink that sneaks up on you. The key is getting that perfect balance between Henny and mixer so it actually freezes. Don't worry, I've done all of the testing for you!

How to Fix Error Messages Related to Alcohol
If you’ve ever tried whipping up a margarita, piña colada, or any frozen cocktail in your Ninja Slushi machine and ended up staring at an error message, or worse, a sad, watery mess. Trust me, I’ve been there. I went through all the trial and error so you don’t have to. Here’s the real reason it happens (and how to fix it).
- Alcohol and Freezing Don’t Mix Well – Alcohol doesn’t freeze like water, so if your drink is too strong, the machine can’t do its job. Too much liquor = no slush. The machine will either skip the shave or refuse to dispense altogether.
- Your Ratios Are Off – The Ninja Slushi needs balance. You’ve got to have the right mix of alcohol and water-based liquid. Too little liquid, and you’ll be scraping ice chunks. Too much, and it’ll pour out like a cocktail instead of a slushie.
- Thick Mixers Can Mess Things Up – Heavy juices, creamy ingredients, or thick syrups can slow the machine down and make your texture clumpy or uneven. Go lighter with those or mix them in after blending.
- Don’t Overfill It – There’s a reason the machine has fill lines, y’all. If you go over that max line, it’s going to struggle to freeze and dispense properly. Keep it in range for the perfect slush every time.
How to Make The Best Cocktails in the Ninja Slushi Machine
If your drink’s too boozy, the Ninja Slushi machine is gonna let you know. You’ll see the temperature lights start flashing one by one from the bottom up, the preset buttons blinking like crazy, and then it’ll start beeping at you every minute for 15 minutes. That’s your cue to cool it on the alcohol and add a splash of something lighter like water or sparkling water to balance things out.
- Keep It at 1–1.5 oz Alcohol per Serving – Anything more, and your drink won’t freeze up right.
- Add a Little Extra Liquid – Water, juice, or mixer helps it blend smooth and thick instead of icy or runny.
- Start with Cold Ingredients – Pre-chilled liquids help the mix freeze faster and stay slushy longer.
- Go Easy on Thick Syrups or Creamy Stuff – If you use them, thin them out with water or juice so the machine doesn’t struggle.
- Respect the Fill Line (64 oz Max) – Overfilling just throws everything off. Stay in that sweet spot for the perfect pour every time.

Frequently Asked Questions and Pro Tips
No ma’am. Hennessy (or any liquor) by itself won’t freeze. Alcohol has a lower freezing point than water. You’ll end up with an error message and no slush. Always mix it with juice, water, or another non-alcoholic liquid.
Stick to 1–1.5 oz of Hennessy per serving. Too much alcohol will stop the machine from freezing properly and can trigger those flashing lights and beeps.
Most likely, it’s too strong or too thick. Add more water, juice, or a lighter mixer, and make sure your ingredients are pre-chilled before pouring them in.
That’s the machine saying, “Too much alcohol!” The temperature control lights will flash one at a time from the bottom up, the presets will blink, and it’ll beep every minute for 15 minutes. Add more water or juice to fix it.
Absolutely, but don’t go past the 64-oz fill line. Overfilling can mess with the freezing and texture.
The trick is to use pre-chilled ingredients. Make sure everything is chilled beforehand, that way it takes 20-25 minutes to process. In general the machine can take up to 45 minutes to process.
