Do I need a protein rest?

What would happen if I use this grain bill without a protein rest?
7# Briess 6-row pale
2# flaked maize
1# Weyermann munich
From what I read the protein rest is needed for more than 25% under-modified malts and adjuncts and the corn is less than 20% of the grain bill. The 6-row has high diastatic power but more protein. Will I just get lots of hot break and chill haze or will there not be enough free amino acids and medium proteins for body and head retention?

You should be fine bypassing the protein rest.

You'll definitely get a lot of hot break. I cannot predict if you will get chill haze.

You probably will make a fine beer without a protein rest, but you'll make a better one with it. Do a thick one, about 1:1.


TL

I should have room if I use boiling water for the second infusion(I use a 5 gal mlt) or I could do a decoction.

Did you watch This video about decoction? It's great.
