I have been having some troubles with my efficiency so I had the LHBS crush the grain a bit finer this time. This is the small stuff that was making it through the false bottom.
First runnings went well, very well. So I stir in my sparge water, wait a couple of minutes then slowly open the valve on the tun and nothing...so I open it further..nothing still...all the way? nope still nothing coming out..STUCK! So I run downstairs, fill up the compressor, crank the pressure up to 80lbs and give a couple of shots back up the valve and wham, I'm back in action.
Mine house ale is 12 lbs of Golden promise and 4 oz of Chinooks. I roast 2 lbs of grain for 30 minutes at 350 and I leave on in the oven for a full hour. It comes out like hoppy single malt scotch. I call it Scottish sunrise. Let me know how this turns out sound good so far..
This is what my setup looks like and the bottom of the false bottom is an open hole right that leads out of the cooler, so anything that can make it around the outside of the false bottom or through the holes in the fb can usually make it through.
Maybe I need to cover the hole with a bit of screen/mesh?
your FB might be floating a bit... I have seen two solutions to this.... One is rather than using flexible tubing use rigid copper so it cannot float up and replace the fittings with compression (this is what i do), the other one is to cut a circle out of plastic and then bolt it to the bottom of the false bottom, so even if it does float no chunks can get in...
