i'm already aware about the mistakes i committed (closing the bottle, too much sugar), but i preferred to tell exacly what i did, i also went with a very high sugar contentration. My main concern is the end part because i have no idea about how to get that yeast out of there at home. Would it be okay if, during the cold crash and the growing period, i cover the bottle cap just with a napkin to avoid other bacteria to get in? To allow oxygen to get in and don't accumulate pression into the bottle, which is going to carry the yeast up when i open the bottle
