Nice build. I like the way you put it together.



Here is a couple of shots of the one I made about 5 years ago. Mine is made of perf screen material. It has .037" diameter holes in it. Mine is tall enough to sit right on the bottom and stick out just a bit. The nice thing about mine is the boil is focused up through the center of the cylinder.



The bottom is made of the same material as the sides.



This is the same material I made my false bottom out of.

Wedge – Measure you kettle free space (space above siphons, plumbing, etc…) to determine how wide/long you want to build it. I choose 10” for a couple reasons. First, I wanted it as big as possible so the hops could freely move around during the boil. Second, my kettle top opening can accommodate up to a 12” OD pipe, but I have fill tube plumbing that sticks out a couple inches from my sidewall.

Once you determine the best size, order up the pipe from your local steel supply or fabrication shop – I couldn’t find a section cut of 10” at McMaster Carr. 304L is common and you only need a 3” min section to make this work. You can probably get a better deal if you buy your mesh from them as well. McMaster’s stainless mesh prices are a bit high. One thing to note is that you can make (2) Hopsters per 48” sheet from McMaster- if you order from them go in with someone else and split the sheet. I ordered the stainless studs and nuts from McMaster.

I used 8x8 mesh because I brew almost exclusively with whole hops and I also have a finer mesh screen on my siphon to stop any small stuff. I’d recommend a finer mesh if you use pellets or are looking to use this as your only screen. What’s cool about this setup, is that you can quickly pop the hose clamp and switch out to a finer/coarser mesh basket in less then a minute.

The most time consuming part of the assembly is rolling the screen. Finer mesh is easier to roll than mesh with thick wire and lots of open space. Use your pipe to roll/form the mesh sidewall around, until it overlaps about 1.5”. Put the pipe clamp on it to hold the screen in place around the pipe at the top. Drill a hole, place a rivet, repeat… all the way down the sidewall. Pay especially close attention to make sure mesh lines up in a straight line all the way down your sidewall.

Before placing the last couple rivets, trace an outline of the circular pipe onto a piece of remaining mesh. Cut it exact or 1/16” larger than the opening because you want it tight. Shove it into the bottom end of the mesh cylinder and stitch it up in there with stainless wire. Roll the bottom of the stainless mesh to eliminate sharp points. Next, drill (3) holes in your pipe to mount the studs and test fit. Hopefully, it fits great, if not, release the clamp and trim off the top if it’s long. If it ends up being too wide you’re pretty much screwed by this point so try not to let that happen ;>)

That’s it.

Hope this helps. If you’re interested in building one but need help finding parts or have questions on assembly, PM me, I’d be glad to help.

Hawgbranch - McMaster’s item number for a 10” worm drive stainless hose clamp is: 54155K44. The clamp that I used was left over from a different project and is a quick release item #: 5215K15. At $44 per, it’s a nice option but not worth the extra cost IMO.

Brew-boy – yep, I almost exclusively use whole hops. I’d recommend a finer mesh screen for pellets. I’m thinking about making a finer basket that I can quick change to when using pellets. I also use a finer screen on my siphon.

Pickles – thanks for the compliment, I appreciate it. If you can wait a week, I’ll try and get some new shots up after I get my BCS and control box mounted later this week. I’m just finishing an upgrade and have the pumps, plumbing, etc… pulled out. I’m hoping to get it put back together before next weekend.

Lonnie Mac - using an old corny is a damn good idea and can cut the cost nearly in half. I wish I had thought of that sooner :>) Can you post some pics when you complete it? I’d definitely like to see it.

GreenMonti – That’s a sweet hopscreen. I like the way it sits in there at the bottom without any studs to hold it up. It makes top access easier as well vs. stud mounted. Very nice build.

anyone build this type of hop stopper and use it for pellet hops? Im thinking about replicating what looks like an awesome hop stopper but wanted to see if anyone has had any problems using all pellets as that is what I primarily brew with. Thanks in advance.

I bought the 20x20 s mesh from Mcmaster and it works just fine. I've used all pellet, cones, and a mix. I would make it hange close to the bottom to make the boil really move the hops.

Do you know the mesh size by chance or better yet have the McMaster part number? Do you use this hop stopper exclusively or do you also have a screen over your dip tube?

9226T001 for the mesh and there should be enough to make the bottom. I just bought some stainless wire 9882K31 and wired it together. Stainless rivets would have been the way to go, but I already had the wire.

I don't use anything over the dip tube. I have a 1/2" 90 degree fitting with a 1/2" nipple and ran it to the corner of the kettle and cut the bottom of the nipple out. I also shaped the end to fit the kettle wall. I joined it to the coupling in the kettle with a stainless union. I put a whirlpool fitting into the kettle and use my pump. Followed wayne1 on here on the design. I went through hop-clog termoil for so long. I tried the bag and hated the way it worked. Made a hopstopper and didn't like where it sat in the middle of the kettle. I still need to fab a new top section like the pig. I just have mine hanging from my "spider" I used for my bag. My last brew had 9oz of pellets and I had no trouble at all. IMO this is the only way to go for hops. Makes IPA brew days go off with out a hitch. Hope it works as well for you if you make one.
