How long do you age a carto?

Title says it all.
Assume liquid is already aged.

As far as I know, cartos do not need to age, other than some time to let the juice soak in uniformly...a few minutes or so. That said, if I'm using a carto for some of my tobacco juices, I do find that first fill is ok, but as I use it and add more juice, over time the flavor becomes far more "real", it deepens and becomes more complex. This is especially true with juices I make from my own tobacco essence formulation, which probably has sugars and other larger biomolecules in it. I don't think this is a time thing as much as what the juice does while it is hot, perhaps some carmelization of the sugars (not good for attys, but cartos are cheap). So perhaps one could say this is "heat-aging". Vendor-bought tobacco juices don't do this much that I have found, nor do non-tobacco juices.
