It's been quite a while since I played Minotaur Hotel, so my memory is a bit rusty, but there was an explanation about where to get the healing wine? since I remember that the hotel cannot generate it, Or is there a limited amount of The healing wine? If that were the case, it would mean that there could come a time when it runs out and Asterios can only rely on its passive regeneration.

i recall there being wine spawns when a new master shows up. i imagine this could be a gift from dyonisius he sneaks in from time to time.
