Testing was done to determine the overall temperature delta between a carboy filled with water and a fermenting carboy in open air located side by side. There has been talk of the temperature deltas but I wanted to see cold hard data in time series fashion. Results can be seen here...

Regarding an update - I cant say I have a whole lot to add today. As I am going to be moving in the near future I haven't put a lot of effort in to this lately. However, this will definitely be built into the dedicated brewing room in the new home. Ill keep you updated once I progress further...

The gauges are from Google Charting apis: http://code.google.com/apis/chart/interactive/docs/gallery/gauge.html

Here is a database I have been putting together with all the yeast strains I am familiar with and the respective attenuation, flocculation, recommended fermentation temperatures, etc. I thought I would pass it on to those who might find it useful. Let me know if I am missing your favorite...

My final goal is to have a web user interface which allows the setpoint or PID parameters to be easily changed on the fly. I'll post more if I get it working...

I modified the PID library from Arduino.cc http://arduino.cc/playground/Code/PIDLibrary I dont have a good answer on the netduino and compatibility though.

Lets get this straight from the start...I do not consider myself an Arduino coding expert...but I have recently taught myself how to send PID controlled data from an Arduino to a web server and display the data real time on a webpage. I thought I would share it for those interested. The full...

So here are the list of beers I am thinking of for the second version of this investigation. Basically the scenario would be these would be the only beers offered and you would have to select at a minimum your top 5 selections for different situations. I selected beers from brewing companies...

Alright, I wasn't initially planning on getting too carried away with this but everyone has now convinced me to get fully carried away with this..Thanks!. It will be a longer version but I don't think most will care about that. I am thinking it will be split out by categories such as session...

From the surface, yes, you can tell that there are a lot of light lagers versus highly flavored craft beers but I am looking for specific detail within those categories such as which beer would a homebrewer prefer Corona or Heineken and even look at the rates for trying beers relative to whether...

So I recently had a debate with an ignoranus over beer sales and the top selling beers and what the beer style preference is for homebrewers. Without getting into details to skew the results of this I figured I would create my own survey and collect the results (you can view them after you take...

Thanks for the recommendations Aaron I like those ideas. I'll see what I can do for the next recording from your list - good stuff!

The yeast is a white labs belgian ale WLP 400. Regarding fermentation pauses, especially when the trub at the bottom rises to the top, my thought is that the hop oils are either quickly shocking the yeast or the oils are reducing the surface tension (defoamer). I cant say I have the answer...

I always use a yeast starter and I always pitch at two degrees lower than my target fermentation temperature. It is key to not change your temperature by more than 2 °F in less than 24 hours or you could potentially shock your yeast. My starter is always prepped to the temperature that I am...

The other thing I don't like about this fermentation is the lack of temperature control. For all beer I make I place the carboy in a water bath and maintain +/- 1°F. Fermenting in open air is terrible temperature control which is why I want to prove that the fermentor gets hot in open air...
