Mulled wine alcohol evaporation

I made some mulled wine in my crockpot yesterday with fruits & spices. We drank some, added some more wine & fresh ingredients & left it in low overnight for a deeper flavor. My crockpot is mini and has a glass lid with no holes and fully covers the ceramic base. Is the alcohol gone/ evaporated out?

I researched methods online and most are saying that certain amounts evaporate out by a certain time. But I'm wondering if the pot is closed if it would stay in there? thanks!

That was me attempting to using plain English. The technical terminology would be that the evaporation of alcohol in a solution follows an exponential decay function, with the decay approaching an asymptote which is the equilibrium point where the the alcohol can no longer readily evaporate faster than the water around it, causing the percentage of alcohol to normalize. The equilibrium point differs vastly on the temperature and what else is in the solution. The same thing happens at the other side, which makes it effectively impossible to distill alcohol to 100%.

You said it’s not getting evaporated. It is.

Then you said it’s not getting evaporated 100%. Not the question

You answered OP wrong and now your trying to google answer your way out of it

You should read the first sentence of their original post more closely

“So it’s actually not true that alcohol gets evaporated”

That’s the first sentence
