It starts going bad (not "flat", except for sparkling wine) immediately, but
it's probably a week before I can start tasting much difference. Apparently
the exposure to oxygen is what does it. They make little gizmos that
replace the air in the bottle with some other gas like nitrogen, then you
cap it, and supposedly that keeps it OK.
