So I know when fruit flies get into your brew, it's game over for that batch. I'm wondering how to know when it's game over. I saw fruit flies around my brewing jar and hanging out on top of the cheesecloth, but I haven't seen any inside the jar. I've checked inside and I don't see anything that looks like eggs or larvae, and I just bought a cotton cloth to put over the top of the jar instead of cheesecloth to prevent any future fruit fly problems. Do people reccomend I scrap this batch since I saw fruit flies around it, or is it fine as long as I don't see them inside? Sorry if this is rambley.
