How Much Wash Is Left In Your Still?

I ran my first wash of UJSSM through last night.

I have a 2.5 gallon pot still and I put in around 2 gallons of wash.

I heated it up to 80 C and then ran it at around 90 C for close to 5 hours. I through out the first 100 mL of foreshots. Kept about 1/2 quart of what appeared to be heads / some hearts. Then I had about another 3/4 quart jar of likker that turned out to be more cloudy than anything. I took a couple spoon samples and it started turning to more of a biting / bitter taste so I shut the still down.

I popped the top off my still and I had a bunch of wash leftover. I didn't measure it. I used used around 1 gallon of the backset to put back in my fermenter for the sour mash.

I'm just curious, should I have that much left in my boiler? It didn't smell like purely water leftover. I did not take measurements of SG of my mash, wasn't included in the directions up front for the UJSSM so I don't have those answers. I'm just curious, on average how much backset is usually left after your run in a pot still? Any advice or comments are appreciated!

Thanks,
E.
