For what it's worth.
Last night I had a very nice and interesting chat with Steve(Vacuumpumpman). He brought up an interesting point about alcohol levels being different at different heights in corboys and tanks. Correct me if I'm wrong but I believe this is called stratification or stratified.
So anyways I asked our winemaker about it today and he said it is only an issue in tanks over 18' tall. He studied/worked for 6 months in Austrilia during harvest time and they actually had huge tanks that would circulate the wine to prevent this from happening. At our level of wine making and most small to medium size wineries would not have to deal with this.

What causes the alcohol levels to vary in these conditions?

So circulating the wine would keep the alc from separating out.

Yep, kind of like adding water when king a wine kit. If you dont stir it up the water will sit on top and youll get a false SG reading amking you think you need to add sugar.

Jon keep in mind this is in extremely large(tall) tanks you would really see the stratification.

....fill it with concrete and use it to roll a long road for a landing strip?
