Ok, so, I had been using a SS mesh hose wrap for a "false bottom" for my 10 gallon rubermaid round cooler and NEVER had a stuck sparge. However, my efficiency bit the big sack when fly sparging but was ok when batch sparging. I have recently bought a 12inch false bottom from Northern Brewer to try and increase my efficiency when fly sparging and I've had two-for-two stuck sparges. I take my time when I sparge (up to 1 hour) but these got stuck right out of the gate. I'm pissed and fed up with the false bottom crap. I did a beer (original recipe for a "Blood orange Black Beefy Hefeweizen") and ,yes, my batch sparge did SLOW DOWN but did not get stuck. Some will ask, "So, Why not stick to what you had???" It is simple, when I sparged, I stirred up the mash really well. I also twisted up my SS hose as well. To do that every time and then replace before the next batch is impractical and in the long run will be expensive. At first I thought it was the "Naked Oats" in the Surly Cynic Clone I did from NB however, the AK47 Pale Mild also got stuck today and I guarantee there ain't no gluten in that beer or anytrhing else to stick that damn sparge. I use a 10 gallon rubbermaid round cooler with a 12inch NortherBrewer false bottom and a 3/8 inch high temp hose (up to 500F) from Midwest Supplies. I vorlauf at a very slow rate and STILL get a stuck EFFING sparge! Can anyone help???? I'm ready to sell the false bottom and go back to my simple sh*t!!!!!!!!!!! Thank you to all
