Bottles Before Woodfall
There is only one bottle before woodfall and that is when you revive Koume. You revive Koume by going into the woods on the first day, when you find her go back to her sister’s potion place. In the potion place you will find Kotake, tell her that her sister is in the woods she will give a red potion to revive her. Just find Koume again and give her the potion by talking to her (don’t target her and use it, that make will you drink it). When she is revived she will be so nice and throw the bottle at you. You got your first bottle, six more to go!
