Blichmann 10g EBiab Mash Volume

[Horsepuncher]

I’ve just acquired as Blichmann 10g kettle with a boil coil that I’m planning on using as my new BIAB set up. It looks like the top of the coil sits at about the 3.25 gallon mark. I’ll have some type of false bottom on top of the coil to protect the grain/bag. I’m having a hard time wrapping my head around what my max grain bill could be. Do I have 10 gallons to work with or 6.75?
I plan on mashing at full volume, and recirculating the mash.

Thanks for any insight.

Only downside to so much space below the FB is that on high gravity brews your mash might be a little stiff due to all the volume below the grain.

For example w/ 16 lbs of grain and 8.25 gallons total water.
Your water to grain in the mash will be 20/16 qt/lb or 1.25 meh not that bad.

The boil coil is very low density, I believe some don’t bother separating the mash grain bag from the element w a FB

Fwiw, your right at your 10 gal mark with this scenario using rackers calculator “can i mash it”

I have a similar setup and I start with 6.5 gallons of strike water and end up sparging with another 1.75 gallons. I have been able to make beers up to 1.070 (15 lbs of grain) with no problem mashing. I haven't really tried to max it out yet though...I'm guessing you could add more water and increase the grain bill.
