Residue on kettle after boiling with a BIAB.

[bazbart]

Hi all,

I've just started BIAB recently with 2 brews under my belt. It's been more downs than ups I have to admit. Each time I boil my wort after mashing for the hour I am getting a lot of residue on the inside of the kettle. It's covering the lid and the exposed internal walls of the kettle. When I add the hons (pellet type) some of the hop residue is on the inside of the kettle also. I'm also getting a lot of particles in the boil which I think is the same residue as on the sides and lid just in the wort.
Am I doing something wrong? Boiling too vigorously?
Have to admit it's putting me off BIAB so would really appreciate any advice or info to put me straight.  Or is this this part of the process? I'm thinking not though.

TIA.

Howdy and welcome.
Sounds normal enough.
Pictures would help though.
What volume is your kettle?
Lid on or off for the boil?

don't fear the foam. It's normal to have this stuff. Some protein is what it mostly would be. The hops debris often  gets stuck to the sides from the boiling motion,quite normal too. Some people put hops in a sock which is handy but if you do that make sure they have of room to agitate in the bag to get full use of them. I like to go commando style meself with the hops to get that full boil out of them.

I've no pics I'm afraid. The residue is brown gunk and only happens during the boil. I have a 30 litre Peco kettle and I usually boil with the lid either ajar or on. I do put the pellets into a sock and then into the wort but even still I still get the greeny coloured residue over the brown. If you know what I mean.
I'm happy you both are saying it's normal was getting worried that I was perhaps overboiling it.

when boiling try keep the lid off.

Will do for future brews. Thanks again.

And clean any gunk off ASAP after each brew. It can harden.

Brewing; it be messy There's a lot of protein break both pre and post boil when working with grain rather than extract. As others have said, boil uncovered and then just get the elbow grease out after a brew and clean it off.

It's totally normally and actually the sign of healthy hot and cold protein brakes, which you need or you possibly end up with chill haze.
