Nothing is visible during bottle conditioning. Most people will open bottles after 2 weeks. I typically wait 4 weeks before drinking a brew. This additional wait time is easier to deal with when you have a few other brews ready to drink.
Nothing to see....Just put them someplace above 70 and don't even think of openning them til they've been in the bottle, AT LEAST 3 weeks....And don't start a "my beer's not carbed yet" thread if they aren't carbed by them...Instead just go read this while you relax and wait for the beer to be ready.
