I tend to miss my efficiency badly so been over sparging and doing an hour boil before any hop additions. Hopefully once the PID and pump are wired up will improve. Could also improve with a new thermometer.
Well i found the root of the problem. The bottom was totally burnt and was a nightmare to get off. I remember not doing a vorlauf and pouring the wort left at the bottom back in so guess it was the flour causing it. I don't have a mill and crushed some specialty malts in the food processor. And that's rubbish! Thought i would of known better by know.
How do people clean their filters. Mine seems to have a build up inside but tried everything can think off. May get a larger one next and a new extra bag to either strain the wort through before boiling or use for boiling the hops.
