Can someone help me identify the mystery substance I found in my fermenter?
I was kegging a batch of stout and saw white substance in the fill line, when I opened the fermenter (after the fill) I saw the white substance pictured. Where it was adhered to the fermenter wall it was fairly thin (a millimeter or two), had a chalky feel when touched. It seemed to have been floating on top of the wort.
Methods/notes
This batch was a full grain stout.
I use RO water and added water conditioning chemicals in the mash water (6.5 gal) as follows:
gypsum 1.2 tsp
epsom salt .2 tsp
calcium chloride .4 tsp
baking soda .8 tsp
I am pretty meticulous in cleaning and sanitizing pre-fill - I use PBW wash and sanitize with starsan
The fermenter was sealed after yeast pitch
This is an Anvil Chronical - I drained trub using the 1.5" port after one week - this pulled in some air.
It has been in the primary fermenter for three weeks.
I left the wort sit overnight - mold has formed (of course) on top of the wort - it does not look like the white stuff pictured.
Thanks
