Hey,
Thought this deserved its own thread. Any idea what this stuff is? This is full boil kettle pre boil, after resting overnight with collected runnings. Below is mash detail.
36 pounds of malt with single decoction and a recirculation/direct fire mash. Did my infusion to 104, rested 20 min. pulled a decoction that took a good 80 minutes to convert then boiled 30 minutes, ran out of propane, and 45 minutes later resumed boil for another 5 min. then Returned to main mash for another 40 mins with recirc and heat, probably because the main mash temp had dropped about 10 -12 degrees. I then mashed out and sparged.
I collected the wort but ran out of daylight and let sit overnight with lid on before the boil on next day. I planned to skim this off, but it was disturbed somehow, and congealed into tape-like strands of faintly white stuff almost translucent, floating on top. I was able to skim them out.
Final post boil chilled wort tasted almost like syrup, so whatever that stuff on top was, I don't think it is harmful to the beer. Maybe the beginnings of a bacterial infection as the wort sat in warm humid pot where could have been nasties in the headspace? But didn't look or smell bad. I wonder if it could've been some type of gelatin from the prolonged low temp rest of the main mash.
