I bought the 600 micron hop spider after my last brew became such a mess. I had experimented with 400 micron and they simply block. I bought an 800 micron and this left most of the hops at the bottom of my brew kettle. This Brau 600 micron is the only one I could find in between 400 and 800. I just made a very hoppy IPA and the results in the brew kettle were fantastic. I adjusted the depth using the multi location holding arm. I set mine at a higher depth out of the brew than I should because I was worried about it blocking and causing an overflow. During the Brew, I used my Wort pump to pump the boiling goodness into the hop spider. It filtered without blocking and after the brew was complete, I had an acceptable amount of hop residue at the bottom of the brew kettle. I have now reset the depth to lower for my next brew. Why everyone does not use one of these I don't know. Fantastic work on the part of Brau. Thanks for solving my brew kettle mess.
The hop filter made it very easy to add hops at different stages during the brewing process and remove them easily. I highly recommend it.
