So I brewed my first allgrain batch last night and because I am brewing in my apartment I am trying to get 6 gallons to boil I threw the lid on and at around 212 degrees I removed the lid to watch for the hot break then I noticed the weirdest thing On the top of the wort is was grey!! Has anyone ever seen this?
I just recreated an ipa that I originally made with extract. I used 2-row and 10L also I used a 10 gallon cooler mash tun.
I used all stainless steel.
