Since then I've not noticed the airlock bubbling. Should I be worried?
If you haven't taken a grav reading you don't know if it has stopped fermenting or not...All you know is your airlock isn't bubbling, or has slowed down, and that is not the same thing.
If your airlock was bubbling and stopped---It doesn't mean fermentation has stopped.
If you airlock isn't bubbling, it doesn't mean your fermentation hasn't started....
If your airlock starts bubbling, it really doesn't matter.
If your airlock NEVER bubbles, it doesn't mean anything is wrong or right.
Your airlock is not a fermentation gauge, it is a VALVE to release excess co2.
So get out of the habit of thinking that an airlock bubble it telling you anything.
Fermentation is not always "dynamic," just because you don't SEE anything happening, doesn't mean that anything's wrong, and also doesn't mean that the yeast are still not working dilligantly away, doing what they've been doing for over 4,000 years....
The only way to truly know what is going on in your fermenter is with your hydrometer.
Like I said here in my blog, which I encourage you to read, Think evaluation before action
you sure as HELL wouldn't want a doctor to start cutting on you unless he used the proper diagnostic instuments like x-rays first, right? You wouldn't want him to just take a look in your eyes briefly and say "I'm cutting into your chest first thing in the morning." You would want them to use the right diagnostic tools
before the slice and dice, right? You'd cry malpractice, I would hope, if they didn't say they were sending you for an MRI and other things before going in....
It's the same with out beer, to know what's going on with your beer, you should check your gravity.
You beer is fine...when you removed your airlock, you VOIDED out any excess co2, so the airlock doesn't necessarily need to bubble.
just relax and walk away for a week....
