At least this 🤏 cold. I’m pretty sure it’s mixed since pure Jägermeister isn’t green.

Alright science nerds how cold does the freezer actually have to be to get a jagerpop that is consistent?

All those who have tried it this morning are currently busy trying to take the pop out.

How much/what’s best to mix with to get a better freezing point? Always looking for new recipes.

there’s a bar in Edinburgh Scotland called Panda and Sons, they bring the spirits to that spot where they can remove the water ice and then add other stuff or mix it up. They have their menu only that gives some details.
My wife and I sampled most of the drinks. Interesting approach but you need some skill and the right equipment to make more than a mess

Thnx, very interesting.

tl;dr Around -23°C (-9°F).
Formula for freezing point depression is:
ΔT~f~ = i * K~f~ * msalvaria@lemmy.blahaj.zone 2 months ago
The bottle is green, the liquid is brown
Karyoplasma@discuss.tchncs.de 2 months ago
Yeah, that’s how it is here as well, so these Jägersicles look fake.

No, at -15 it turns green /s
Tar_alcaran@sh.itjust.works 2 months ago
All the other stuff in the drink might lower it a bit though, especially the 14% (!!!) sugar.

You’re right, I edited it.

I did not know about that formula, very cool. It seems linear (unless the molality is a non-linear term), whereas the empirical data gets pretty whacky at higher concentrations. Maybe its validity is for low concentrations? I’m getting closer to -27C from this plot

Either way that’s getting close to “don’t lick it” temperatures lol!
Karyoplasma@discuss.tchncs.de 2 months ago
The figure you’ve linked plots concentration by weight (wt.%), while the alcohol content of drinks is usually given in volume percent (v/v). Ethanol is less dense than water, so a 30% concentration by weight is a higher concentration by volume.
Imagine a 100g solution of 30wt.% alcohol. That means that 30g are ethanol and 70% are water. the 70g of water translate to 70ml volume (density 1g/ml) and the 30g of ethanol translate to 30/0.789 = 38.02ml. So in total, you would have 108.02ml of liquid and the concentration of ethanol by volume would be 38.02/108.02 = 35.2%.
Why it gets wacky at the end: Ethanol freezes at -114°C, water freezes at 0°C, but at specific concentrations, the eutectic composition, the solution freezes at a lower point than either of its constituents. The eutectic point is the lowest possible freezing point of a solution. The formula I gave is not applicable to eutectic solutions and is an approximation based on perfect solutions (which in reality don’t really exist).

There is only one error in your equations (and that doesn’t change much about your point) is that the volume of that mixture is slightly lower.

Amazing, thanks for the clarification!

“it has an alcohol by volume of 35% (61 degrees proof, or US 70 proof)”
Karyoplasma@discuss.tchncs.de 2 months ago
Whoops. Well I forgot to account for sugar and other stuff which decrease freezing temperature as well, so the result might still be around right. It’s an ok ballpark at least. Precisely calculating a solutions freezing temperature when it has that many different solubles is pretty hard.

It’s brown everywhere else.

Wouldn’t surprise me, they do love their food dyes over there
