I have now a Grainfather Brew-Device and I brewed about 20 batches with it already. It’s very nice and easy to use. Last time I cleaned it without removing the control panel and I had some water coming in the display. I tried to brew manually with it and missed to stop at the correct mash temperature. It went up too high and I made the big mistake to add the grain at 180ºF. The problem came with the fermentation. The original Gravity went only down to 1.030 starting at 1.049! My Lager would not ferment to the correct Gravity.  I had to realize that there was no Beta amylase at that high Temperature, which let me sit on long chain sugars which are not fermentable for yeast. I dumped the worth with tears in my eyes.
