Usually I can see it start settling while it's mixing but it doesn't fully settle during mixing
Usually I'll be able to see a noticeable difference in 24 hours but I'm actually not fully sure
If I don't notice it settled enough within a couple weeks I'll add a bit more concentrated alum solution to each settling container and shake the hell out of it
But in general having one container worth of alcohol settling while the other one is able to use is a good idea because settling can take awhile if the alum solution isn't very concentrated
Edit: By concentrated alum solution I mean like ~~25~~ 50 grams per 100ml of distilled water, it should fully dissolve before you add it to the alcohol.
Edit 2: I double checked my notes, it's actually 50g per 100ml. It helps to mix it of the water is warm (NOT BOILING!!! ONLY HEAT THE WATER!!! And have it just warm enough to dissolve the alum. Then wait for it to cool down a lot, like barely warm.)
