Brewed this up this past weekend and brewday was a nightmare (due mostly to my lack of preparation). I got the king of all stuck mashes by a) crushing the grain too fine, b) not adding enough rice hulls to the bottom of the MLT, c) having a piss poor manifold (pex pipe with mesh bag tied around it, and c)mixing the pumpkin in at the bottom of the MLT.
All of that could have been completely avoided if I just had my head on straight that morning. I ended up having to scoop nearly the entire mash out into another bucket, filling the manifold ‘bag’ with about a gallon of rice hulls, scooping mash back in, and draining.
Oh, and one of my chugger pumps decided to die on me mid sparge.
I think all the rice hull affected the efficiency, as I ended up around 1.055 OG.
Then my last mistake was dumping hop pellets right into the kettle (I use a plate chiller-doh)
But I didn’t forget the pumpkin spice so the beer will be a hit with the family.
