My 10 gallon IPA recipe has almost a pound of hops added from 15 minutes through whirlpool. I have no problem whirlpooling for 30 minutes and letting it settle for 20-30 minutes. There is a nice hop cone from the whirlpool and the hop blocker definitely blocks significantly more for me than just letting things settle. I've never had it clog but I don't rush it into the fermenter so dial back your pump. I'm getting very clear wort and finished beer. I use the Blichmann kettle and hop rocket as well. Believe it or not this pic is wort clarity going into the fermenter. http://oi63.tinypic.com/24v8ymf.jpg

It keeps out most of the junk. Will clog and it's not always accessible to clean.

The build on this is solid and attractive but it clogs very easily and I suspect is not allowing enough circulation for full hopping of the brew.

Works well and does what it is supposed to do. Another quality product from blichmann

Filter - 5 stars doesn't clog and filters really well Usability - 2 stars. You can't whirlpool with it in a small kettle. I use a 10 gallon kettle and i haven't figured out a good way to get it going yet. Without a whirlpool this thing loses a ton of wer to the trub

I made my own counter-flow chiller (from J. Palmer's "How To Brew") with 1/4" copper refrigerator water line tubing and a heavy duty garden hose and a little 1/2" copper tubing (for the ends). The leaf hops filter the hot break from going into the fermenter and the hop blocker does a great job of blocking the junk. I made a Pilsner with a pound of Saaz (14 gal. batch) and the hot break stayed with the leaves. I would not think it would work so good with pellets. And I use the 20 gal. Blich Boilermaker. So... ya gotta have a dip tube to use it.

It kind of works but it's a hassle. You need a way to raise the level you better not tip it you have to whirlpool and make sure not to bump it. I find it easier to just use a mesh hops bag.

I believe the Blichmann hopblocker was designed to work with Blichmann kettles. I found it necessary to design a siphon tube for my kettle. After doing so it worked great. Would recommend this product to any home brewer that likes to design/build.

It's simple. You want to block those hops from entering your carboy or worse your Blichmann Therminator? Use this. I have tried other methods from cheap to expensive and this elegantly solves the problem of proteinaceous matter while maintaining a good siphon. Yeah. Those other methods often end up with a crazy vacuum that will leave a gallon or more of your wort in your kettle. Once again Blichmann delivers with a solution so simple it makes you wish you had a large quantity of high-quality stainless steel to make your own fancy devices. Or you can just buy this one.

Blichmann hopblocker does just what it says!!! After a 15 min whirlpool and fallowing the instruction kept just about all the hop matter in the kettle. Easy easy
