I entered my recipe into BeerSmith and picked double decoction mash.
The instructions are:
Add 7.76qts of water at 127
hold at 122 for 35 minutes
Decoct 2.5qts of mash and boil it
Hold at 147 for 20 minutes
Decoct 1.5 qts of mash and boil it
Hold at 158 for 20 minutes
Heat to 168 and hold for 10 minutes.
Sparge with 2.2 gallons of 168 water
Does these seem right? After searching here and looking at How To Brew again, it doesn't seem right to me.
From HTB, I would do a protein rest at 122 and hold. Then pull 1/3 of the mash and heat to 147 and hold. Boil that and then put enough into the mash tun to bring it to 158 and hold. Then take another 1/3 or so and heat to 160 and hold. Bring that to a boil and add it all back into the mash tun for mash out.
From BeerSmith, it seems like it wants me to do the protein rest then pull 2.5qts and boil it then let it rest at 147. To me that seems backwards. Wouldn't I want to bring it to 147 to rest then boil?
