As it turns out I misread the SG and it is now the FG and it is 1.020
I did a forced fermentation test on a 0.4 L sample. I pitched an entire package of safale s-04 (11G) into the sample. And let it sit beside the fermentation bucket in the fermentation chamber at 19°C for 4 days.
There where absolutely no signs of fermentation in the sample during those 4 days. I did an hydrometer reading of the sample prior to pitching the additional yeast to the sample. It was 1.020.
I added 2 links to two pictures of the hydrometer readings (couldn't figure out how to upload them or get the image thing to work) . First picture/link is of the hydrometer reading of the main brew 4 days after the forced fermentation sample was taken. The second is of the forced fermentation test reading.
You may notice that the forced fermentation test reading is 1.024 the gravity has increased by 4. I believe that is the yeast that has not flocculated due to the lack of fermentable sugars in the sample. That is the only explanation I could find for this. https://pasteboard.co/I4cLolk5.jpghttps://pasteboard.co/I4cKkWV.jpg
Unfortunately the fermentation is finished at FG = 1.020. I can't fantom why. It would imply that I have mashed at temperatures in excess of 70°C which in turn imply that I have 3 broken thermometers (one builtin digital, one external analog and an additional external digital) Which in it self is a bit strange.
Anybody that has an idea of what could have caused this?
