My wife got me this beer making kit for my birthday. The first two brews failed horribly due to bad sanitation, but the third one, an American Pale Ale, turned out alright. The only thing I didn't like about it, was that it very heavy, not unlike certain Belgian, quadruple beer.
I'm not too sure what caused it, but my guess is the fact that we've had a few very hot days while it was fermenting. It's either that, I misunderstood this page completely.
Anyway, as you can see, the kit contains a 1 gallon glass fermenter and I would like to find a way to constantly measure the temperature of my wort as it's fermenting. How would I measure that inside that glass fermenter? What kind of temperature sensor should I use?
In the future, I want to hook up said sensor to a small computer (Raspberry Pi, Arduino, etc.) so I can perform actual temperature control based on the temperature, but I'm having a hard time finding a method that doesn't involve making holes in the fermenter and simply sticking the sensor in through that and just using epoxy to close the hole and making it air tight.
I guess my question is: what's the best method to accurately measure the temperature of the wort inside my 1 gallon glass fermenter? Are there any wireless, waterproof temperature sensors out there that I can simply sanitize and toss in the fermenter or is that too simplistic?
Thanks for your help!
