I just brewed a strong Dusseldorf Alt, commonly known as a Sticke Alt, pitching a June 2008 tube of White Labs WLP 036, their Premier Series strain of Dusseldorf Alt. The age of the yeast was a concern, so I built up a 2000ml starter over a week – uhh, not to worry, it’s churning like crazy, and the blowoff jug is now dark with expended wort.
That high-tech gadget on the carboy is a digital temperature probe with a styrofoam insulator and copious amounts of tape – the insulation is a method to obtain the temp of the wort, rather than the frig. The controller is plugged into a low-heat dehydrator bottom, which supplies enough heat to maintain the wort temp at 60° for primary fermentation of this yeast (if you wanted to cool the wort, you just plug the controller into the frig). Once I finish primary, I will crash both the Alt and the Pils in the background down to 36° for a month-long lager.
