I'm a noob and I brewed my first batch on July 6th. It's a 5 gal batch of an American Wheat extract kit. The OG was 1.043 and today, five days later it's at 1.013. The airlock is bubbling about once every 40 seconds. I'll take another hydrometer reading tomorrow night, but I wasn't expecting the difference to be that much this soon. Is it on track? Should I wait another few days before bottling? My understanding is that it's supposed to ferment for at least a week, the air lock should bubble about once per minute and the hydrometer reading should be steady before I start bottling. I guess what I'm really looking for is affirmation that everything is still okay.
