…the worm clamp fell off my hop spider as I was removing it from the kettle and the bag of pellet hop sludge went crashing into my lovely, clear wort.
I was really enjoying the first time using my new March pump and everything was going perfectly until flame out. Just two more things to do before pitching: remove the hop spider and chill the wort. Then one seemingly inconsequential piece of equipment fails, ruining my otherwise great day.
Plate chiller clogged. I had to break out the auto-siphon to get the wort into the carboy. Of course the funnel clogged. My efficiency went into the crapper, because I had counted on only having to leave about 1/2 gallon behind. Had to leave much more than that.
