does the sparge get stuck due to the grain crush? or is it more a factor the MT?
Not sure what the issue is actually. I made a kolsch this past weekend and decided to open the valve all the way (I used about 1/4 lb rice hulls) once the grain bed appeared set. It stuck within a minute. SO I stirred the grain bed and let set another 10 minutes and sparged as normal with no issues. I use the same set up as many others (SS Braided line from Hot water heater hose). As long as I don't open my valve all the way, I'm usually ok. Its really no big deal, my entire brew day lasts about 4.5 hours so Its not like it takes me all day to make beer because my sparge isn't as fast as I would like it. I get great efficiency so, it is what it is
