Well, I'm looking for being able to find when fermentation is complete of course, but I envision being able to plot rate of change of the SG, which would give me a clear idea of how the yeast activity ramps up, and then tapers off. That would be achievable by monitoring CO2 I'm sure, but I think it ...

Engineer- The bubble counter makes the most sense to me. Hell, you could put a microphone next to it and count the clicks, plot vs. time. Mead? OMG! My batch of that prehistoric vile fluid was horrid! Maybe the honey was foul. THREADJACK! How long did you age it? PM me if you like with the specific...

What's wrong with the usual recommended method of monitoring the specific gravity of the batch (wort or mash etc) with a floating hydrometer? Nothing's wrong with it per se, I'm just interested in being able to monitor yeast performance without having to open the bucket/carboy; mostly to see how ye...

The submerged refractometer idea seems interesting; can you point me in the right direction to explore those further? I did some basic googling for different kinds of refractometers but my search terms must have been such that i didn't see that particular type of device. Given the batch size that I ...

Need help monitoring specific gravity or alcohol content

So in addition to being a newbie electronics hobbyist, I'm also a pretty accomplished homebrewer. For a while now I've had in my head an idea for monitoring fermentation progress via a PIC and an RS232 or USB link to a PC. My problem however lies in the proper way to monitor fermentation. The way I ...
