MASH

Brewing Processes
1

Once grain mesh bag is drained, I always immediately go to boil.
Is there a benefit waiting until the mash is settled, and materiel removed before the boil ?

If so, how long to safely wait ?

Thanks

No benefit that I’ve found

some folks say so, some folks say no. Both are probably making fine beer. I try to get clear wort from my mash into my boil, and from my boil into my fermenter.

Thanks.
I mash & boil in the same pot on the stove.
It gets to a boil quickly that way.

Didn’t think it was an issue, had to be sure.
After chilling a lot is left behind when transferring to fermenter.

Thanks

You are confusing different topics.

  1. If you want more clarity from the mash, you can use a finer bag. Separation by precipitation, which is what you originally asked, is not commonly done. Thus, no reason to do it.
  2. During the boil, proteins that changed configuration due to heat aggregate and form clumps that precipitate upon cooling. This process is enhanced by various finings that precipitate not only more proteins but also polyphenols. So, precipitation after boil YES.

Clarity is not an issue for me.
Thanks

I don’t worry about the mash runoff being clear, just the wort into the fermenter, for the most part.  Even then, it’s not a huge deal to me.  If I am going with a HERMS, I get very clear wort from the mash, but just as often, I just do A BIAB mash and stir a few times during the mash, accepting the run off as it comes from the mash tun after a short vorlauf (or not).  Cheers!

Here are a couple experiments run by Brulosophy relating to kettle trub into the fermenter:
