I have to leave something behind. That is the whole purpose of the whirlpool and domed bottom. I leave the hop pellets and hot break in the kettle. The solids with a small amount of liquid make up the 0.625 gallons.
I plan my brews so I get 5 gallons exactly in my kegs. I don't waste any amount of liquid. I also do not want any solids in my fermenters.
This is a concept that seems foreign to most homebrewers. They try to get everything possible into the fermenter. I DON'T want everything. I only want the fermentable liquid. I ferment 5.5-5.8 gallons of liquid so I do get 5 gallons in kegs.
Carrying this out to an extreme, the COORS pilot brewery had a 30 barrel brewhouse. and 10 barrel fermenters. They only fermented the middle 10 barrels of the run. The first and last 10 barrels were dumped. When I asked why, I was told they just wanted the "best" liquid with the least amount of solids.
