Another iteration of the Never Ending Hefe. The goal here is to put to test the idea that ramping up wort temperature will increase the production of esters in a yeast such as WLP300. I’ve previously attempted ramping with this yeast in my ferm. chamber, but the control there was an ambient one and didn’t offer precise control of the actual wort temperature. With a recent craigslist score the wort can now be put into an enclosed refrigerator with the control box probe submerged in the wort. This system is able to keep the internal wort temp within 1° of the target.
