I ferment my beer at my parents house because its the only place I have access to stable temperatures, and their genius foreign exchange student dragged a sleeping bag across my bucket fermenter and knocked the airlock off in the process. The beer is a robust porter and has been in there for three weeks. The airlock was off for a day before my Dad saw it and put it back on. Has this kind of thing happened to anyone else? Is infection my only concern or also oxidation? Thanks.
Edit: Sorry, probably not the best choice of forum section.
