What happens when the yeast stop farting?

Seeing that airlock bubble is a good thing. It lets you know "stuffs happening", the wort is becoming beer... I always think of the bubbles as yeast farts. Gassy yeast are happy yeast, and happy yeast make happy beer. At least that's my theory...

Most home brewing directions and how-to books I've read say the bubbles should keep coming for about 5 - 7 days. In this case, I brewed last Sunday, and by Wednesday, the bubbles stopped. I'll admit, I'm a little concerned...

I was so concerned that I called the guy at my local home brew supply shop. According to him, I shouldn't be worried. But he admitted he was more of a wine making guy, I guess the beer guy was out sick or something, he really didn't say...

So the wine guy said I should stick to the plan, and come Monday (which is an off day at work for me! Yeah!) I should take a reading with the hydrometer, and if was where it should be I could bottle. So, I'm going to stand bye and see what happens.

Unless someone out there has a better suggestion? It's only Sat morning, if I need to do something to save this beer, please chime in and let me know...
