Normally, I put a false bottom in my 10 gallon Polarware kettle to keep to the whole hops from clogging the ball valve when I make my APA's and IPA's. This time, however, I need to make a bigger batch. I have a 20 gallon Polarware kettle, but no false bottom. I have a 45 degree copper pipe elbow (pointed downward, of course) that's threaded into the inside of the kettle. Is there a simple, low-tech way to keep the whole hops from clogging the ball valve? Yeah...I could bag everything, but I like the hops to be more "exposed" to the wort.
