First Rum Strip: Sediment in strip

[Mattmmmax]

Hey y’all. Stripped my first rum wash today. Everything went smoothly but since it’s my first run, thought I’d come here to make sure all is well.

Recipe: pugirum
Wash: 5gal
Yield: 1.5 gal (down to 18% at the spout)
Setup: T500 w/ alembic copper pot still
Still has been used multiple times, and is cleaned regularly.

I let the wash naturally settle for a week after fermentation ended. I carefully siphoned the liquid off the top into the boiler.

First half of the strip was uneventful. Second half I noticed a bit of sediment in the lip of my funnel. To me it just looked like by product of the molasses, touched it, slightly grainy but oh boy did it stink. We’re talking rotten fish odor. Washed my hands three times and still smell it. I used food grade unsulfered black strap molasses. No scorching on the bottom of the boiler and I used a defoaming agent to prevent bubbling an puking.

Is this normal for a rum?
