Hi all Siphoning an IPA from carboy to bottling bucket today, I changed my usual process and decided to filter out the hops bits (it hadn't fully settled out). I put a small square of swiss viole over the end of the auto-siphon (there is an push on bit that goes over the end of the autosiphon so I jammed it in between). Strange thing happened - the CO2 was appearing in bubbles in the siphon tube - in a big way! It's the first time I've tried to filter the hops, so not sure if this is a common occurrence????? It freaked me out so I stopped and removed the 'filter'. Back to normal then with a bubble free transfer. In the photo you can see the bubbles appearing, then becoming 'foam' further down the tube. Is this an expected result from the filter?
