How much excess/leftover wort do you guys with a 10.5 have left in the foundry after transferring to a fermenter?
I ferment and serve in a corny keg and after transferring I had around 1.5g left in the foundry. I like having some left behind as I not want to transfer the hop matter and trub, but it seems like a lot of waste.
Ive been looking into getting an all rounder lately. With that i am thinking i can empty the foundry to the all rounder and send a full 5g of clean beer to the keg post fermentation.
I usually have about a half gallon to a gallon left over. To help minimize loss, I like to take a fine mesh nylon bag and dump the remaining wort and trub though it.
Depending on what fermenter I'm using, I sometimes have to use my funnel and place the bag in it and tie the draw sting tight. I soak the bag and funnel in sanitizer before using it, and then wring it out. The bag usually clogs a little so I just lift it up and gently roll all the trub back and forth inside the bag and it drains out quite a bit. All the trub/hop matter clumps up after a while of gently rolling it in the bag and it all drains out and practically looks dry after a few minutes of doing this. That's when I call it good and remove the bag with everything left behind.
I usually gain about another half gallon in my fermenter by doing this, and I experience no off flavors, astringentcy, tannins, or anything.
