Yes they acculmulate and 4 A rank bottles still give you 100% to unlock, so it may not be as bad as you think.

But still, I'm not sure how they will introduce the bottles, hopefully as daily quest by replacing sat or sun's wizard training or more likely as dungeon rewards for all future events.

Of course the worst case would be only available as IAP.
