As a chemical engineer ( my profession was founded to stop steam engines exploding ) I must warn this is incredibly unsafe if the pressure vessel is ever to be used for pressurised gasses again. You have no way of measuring the pressure exerted by the ice and it almost certainly exceeds the working pressure of the vessel. This can weaken the pressure vessel and when once again filled with pressurised gas it can lead to a failure which can cause injury or death. In discussing a danger of using the pressure vessel for gas and liquid mixtures as intended after doing this process, I by no means imply the safety of the process described in the video and do not encourage people to use pressure vessels outside of their design specifications

[@gumplebumpproductions]

Freeze a cocktail using a whole bunch of math to figure how much water is necessary for freezing. The pressure can’t expand so it all gets driven inward. When it thaws pop it a bottle, chill it again in the fridge, stir with ice because it’s clearly still not diluted and cold enough, strain and enjoy.

[@KevinKos]

[@jonasfeddersen551]

I'm not fully aware of new innovative techniques in the world of bartending, but I work in the coffee industry where baristas for competitions use freezedestilled milk in the milk drinks- this is a way to concentrate said milk and make a higher sugar and fat content without altering the flavour. I mean this could be applied to make some of the non alcoholic ingredients that goes into a cocktail? I presumes juices of fruits or citruses would be freeze-destill-able? Cheers:)

[@timkloppenburg1254]

Thank you for this amazing video, Kevin. This freezing technique made me think of a different freezing technique, Freeze destillation. It's the opposite of normal destillation. Not using the different boiling temperatures, but using the different thawing temperatures for seperating liquids. it's been used in the beer industry in the Netherlands (I've got a 26%abv freeze distilled beer at home), but I haven't heard it being using in the mixology industry. Have you heard of it ever being used?

[@KevinKos]

I have heard of it. In fact, Iain has some similar techniques as you described. Switching is the one that really caught my attention, but it's hard to make it at home with a regular freezer. Thank you!

[@jordanl2317]

As for the colour leeching, I would suggest the ice crystals disrupt the cell walls of whatever you’re diffusing and release coloured compounds in the same way as the trapped flavour compounds we’re doing this for

[@tjonesjfk]

[@KevinKos]

let me know how you like it! Cheers!

[@ibrahimkrhan8599]

The sous-pression technique seems intriguing, particularly when taking into account the applications of liquid nitrogen for altering flavor and texture. The low temperature can be highly beneficial. However, I have some concerns. It is not a particularly simple method, especially in terms of waiting time, and I wonder if the results are truly worth the effort. Rapid infusion may not deliver the best results, but its speed and efficiency make it a worthwhile option. Alternatively, another method involves freezing the material, such as raspberries, and then placing them in the desired spirit. After a day, the frozen item begins to release its aroma as some cells break down during the melting process, infusing the spirit with ease. Is there really a significant difference between this method and the sous-pression technique?

Hope we will have a chance to visit Panda&Sons and try some cocktails there! Awesome Ian!

[@KevinKos]

[@andrewb9942]

Cool technique, and definitely building pressure in that container, but it likely won't freeze more than a litttle but because the freezing point declines as pressure increases. Just be careful with how cold your freezer is: water can exert hundreds of atmospheres of pressure from freezing expansion force, which can cause even thick steel pipes to burst.

[@phantomhandofcocktailtime6911]

Very interesting! The Manhattan seemed quite diluted… at 45%, that's much more than a little melt from ice while stirring to chill if making normally. Did the cocktail not taste… thin?

[@KevinKos]

45% sounds like a lot, but it's not too much. The recipe is from liquid intelligence, where Dave Arnold used the same dilution and alc vol in his Manhattan. You will be surprised how much water we get by stirring and chilling. However, my first try was with less dilution, but it didn't freeze in a regular freezer because of the higher alcohol volume.

[@photojoseph]

@@KevinKos fascinating!

[@ibrahimkrhan8599]

The dilution might seem high because people typically calculate it based on the final product's volume. However, in this case, the dilution is determined by considering the individual ingredients' volume during the cocktail's preparation. This method provides an understanding of the dilution in relation to the components used. When assessing the dilution based on the end product, the value is approximately 30-31 percent, offering a different perspective on the overall mixture.

[@coco805]

I don't suggest measuring volumes using a beaker, even if there are graduation on it. The precision of this measurement is often 15% off or more as the markings are just painted on with a screen printing and are not calibrated. Since you have graduated cylinders, you should use those instead - the precision there is closer to 1-2%. Cheers from a chemist!

[@sebastiantillmann1669]

[@user-dm1tv6nl2e]

This sounds like a couple of things are happening and id be curious how they compare to not either not freezing, or freezing only the grapes. 1. I've heard from other videosthat putting alcohol in the freezer damages flavora (i assume oils or other compounds are being broken down). I assume this is happening with the various alcohols in the cocktail. 2. Grape cell ealls are being damaged by freezing and thawing, allowing an amount of juice to escape (with a possible contribution from the skins). I'd be curious how fresh pressed grape juice compares, likely a more present flavor. 3. I'm curious if the inventor of the technique tried using this method for fractal distillation of the cocktail, allowing water to be removed to concentrate.

[@adashofbitter]

I'm not completely sold on this. Is there a benefit to this as opposed to rapid infusion? One thing that puts me off is that the drinks are prediluted but to chill them again you need to stir them over ice, diluting them even more.

[@thomasdavis8049]

I think this would have been more interesting to compare the notes using rapid infusion vs the freezing technique. I’m still not sure it would be different.

[@eyespy3001]

Agreed. In fact, I thought that’s where this video was heading when I saw the iSi whipper, but unfortunately that’s not what we got. To me, this technique seems like a waste of time to achieve what can be achieved in minutes with rapid infusion.

[@newluke500]

Hey Kevin coming from the coffee world trying to expand my knowledge of cocktails and technique(for competions and fun!) is there a reason to use ml volume measurements instead of weighing in grams? Specifically for smaller measurements, I know see how using ml would be easier for larger volumes. Love your content by the way!

[@erwinseifert8211]

Basically because its a more precise way to measure out volume rather than other measurements because not every product has the same density.

[@SiCibartender]

@kevinkos first, thank you so much for another useful lesson! second, I have a lot of questions but the one I would like to ask is: is it possible to use this technique with cocktails that have juices too? Thanks in advance!

Does this technique work well, or any different, with citrus+sugar mixed drinks?

[@alessandromichelacci4464]

Sorry but I didn't get one thing: why you stirred the first cocktail before serving, adding diluition, and serves the manhattan straight out the bottles without doing the same? What does change from preparing the first cocktail with the keg and the second one with the cream whipper?

Kevin, do you think that this technique damages the keg for using with its regular use later (meaning CO2 pressure)?

[@KevinKos]

I don't think so. It's expanded slightly, but I think there shouldn't be a problem. However, if you want to be 100% sure, it's best to have a ker special for this technique.

It might, but I don't see it as a neccesary step for the super juice.

[@maximkuleshov8852]

How it's different from jacking - when you freeze a fruit and let it thaw in spirit? It seems more involved in terms of equipment, time and effort. I.e. I would just freeze grapes and put them in gin

What about using herbs like mint or basil with the sous pression techniqe? Or even citric peels. Would the flavour be overwhelming or maby bitter with the peels?

Great channel and mouthwatering cocktails, but... this time the 'science' is completely wrong. 😞1) This pressure does not affect liquid or solid ingredients in any way (it would affect things containing gases, like oak chips). 2) The pressure is very low, the containers yield readily and thus limit the pressure buildup (the 'freezing pressure' of water is ~ 40 000 PSI, only a gun barrel could handle that) 3) The only effect here is the formation of ice crystals, which rupture the cell walls of the grapes and release the contents more freely (do a blind test without the 'pressure' vessel to be convinced). Again: great results, but wrong explanation. Freezing can be used to do a number of other things (some perhaps illegal!), too, but the pressure effect is just imagination.
