I brewed this up yesterday, and while everything turned out fine there was a huge headache in the middle. Let this serve as a public service announcement for BIABers.
I do full volume BIAB, which is normally a very easy process. However, this time around the pumpkin almost completely clogged up the bag. When the mash was done I went to the lift the bag out to let it sit on a strainer, but I could hardly lift it. I look down and it's because nearly 2/3rds of the wort was inside the mesh bag, only 1/3rd remained in the kettle. The mushy pumpkin coated the sides of the bag and prevented the wort from easily draining. It's like it was turned into a garbage bag. The bag was so heavy, large, and lacked structure so I wasn't really sure what to do. I couldn't just set it on the strainer as wort would have gone everywhere.
I settled on putting the bag back in the kettle and I scooped out the grains/pumpkin with a hand strainer, let the wort drain, and dumped the grains in a separate kettle. This took forever because I could only get a bit at a time without scooping out all the wort with it as well. Once I got maybe 3/4ths of the grains out the bag was small and light enough to work with so that I could get the wort out of it. Then I scooped the grains back into the bag to let them drain, as normal, back into the kettle.
It added at least an extra hour to the process. Next time I will make sure to put the pumpkin in it's own bag so that I can work with it on a much smaller scale.
