Beer Church is a group of beer (and a bit of wine) aficionados at Pumping Station: One. Originally a beer tasting and science discussion group, lately Beer Church has been focusing more and more on brewing. Brewing Station: One is the small work area and storage facility in the shop devoted to brewing.

Contact/Participation

Events will be posted to the PS:One blog and calendar and the beer church twitter. Anyone is welcome, even non-members of PS:One. Want to brew something? Tell us about it via our twitter or the PS:One mailing lists. You must be 21 to participate in Beer Church.

Events

Semi-biweekly Beer Church gatherings take place some Sundays at noon. They generally follow a format of meet & greet, pot luck beer tasting, brwing, and discussion of beer, life, and everything.

Brewing Station: One

Brewing Station: One is a steel shelving unit converted into a storage unit above for keeping clean brewing gear (pots, carboys, bottles, bottling equipment, corks, wort chillers, kegs, etc) and a temperature controlled fermenting chamber below. We brew in the loading dock.

Potential

Hardware and Software Projects

Chillmon

Chillmon has its own wiki page, but suffice it to say that it makes sure the temperature is right for fermenting.

  • Rebuild Chillmon on Occidentalis
  • Configure Chillmon application to use shared account
  • Replace temp sensors with DS18B20 for more accuracy
  • EPICS integration:
    • Expose Chillmon control variables to EPICS
    • Create EPICS control screens
    • Investigate EPICS web interface
    • Display screen for Chillmon

Brewing Station: One

  • Electrical insulation of contactor terminals
  • Experiment: When the chiller turns off, does it blow hot air into the fermenting space?
  • Experiment: In the winter, will the shop drop below our fermentation temperatures, and will we need a heater?
  • Real time monitoring of temperature, specific gravity

Brewing

  • Need way to make sterile priming sugar mixture
  • Modify Keggles for brewing:
    • Boil kettle
    • Mash tun
    • Hot liquor tun (inaccurately named; this is for sparge water)
  • Build RIMS or HERMS
    • Propane solenoid, thermocouple, and igniter under PID control (Arduino)
    • Pump, flow meter run by microcontroller (Arduino)
    • Multiple temperature probes (Arduino)
    • Safety gear:
      • Alarm system (stuck flow, propane flame blew out) (Arduino)
      • Emergency shut off switch
    • Raspberry Pi controlling the above via EPICS

Dispensing

We have a donated refrigerator; converted to kegerator. It's connected to the bar & draft tower, and working. We currently have 2 taps. We want to upgrade to 4 taps. Eric currently is holding the cash for that project, it's $73.59 of the way into the needed $176 for the upgrades.

TODOS:

  • the aforementioned tap upgrade
  • temperature monitoring inside the fridge & in the draft tower.
  • upgrade drain system for drip tray
  • make custom tap handles
