This week I take a look at the Anvil Kettle Strainer, which is actually a pretty efficient way to separate your hops and trub from the wort after the boil when beer brewing.
The Anvil Kettle Strainer
As I covered in an earlier article, I upgraded to a Blichmann BrewEasy 10 gal system last year when I transitioned to electric brewing. Full disclosure: John Blichmann is both a sponsor of my podcast and a friend, so I asked him what worked best for separating hops from my wort so it won’t plug up my therminator plate chiller? John told me to get an Anvil Kettle Strainer.
I was a bit skeptical. Originally I looked at purchasing a hop basket which is simply a screen basket that you hang in the kettle, but I also knew by experience that these can be a bit of a pain as hops tend to gum up the screen and sometimes create a complete blockage. It is always a delicate balance trying to get a screen with the right size to block the hops without gumming up and reducing utilization.
Other alternatives include hop bags, or some kind of hop blocker which attaches to the bottom of the kettle drain. Hop bags work well but obviously you need to keep purchasing new ones and also make sure you have the right size for the amount of hops you want to use. The kettle drain filters work similar to the anvil strainer but typically have a screen which again can gum up.
Blichmann was insistent – so I got one of his kettle strainers which conveniently fits right over the end of the dip tube on his boilermaker kettles. It has two braided stainless steel arms that provide a good wort flow but also filter out the hop bits.
Kettle Strainer Performance
Honestly I was shocked that this sim
ple device works as well as it does. I did not have to worry about bags or a screen jamming, and just added the hops directly to the kettle to get full hop utilization. Unlike a conventional screen or hop blocker, I get a steady wort flow through the strainer after the boil, and almost no hop bits in the finished wort. I always backflush my plate chiller immediately after use, but have found very little hop matter when backflushing.
I believe it is at least as effective as a very fine mesh screen at eliminating hop debris, with the significant advantage of not being subject to blockage. I can usually draw all but the very thick sludge at the bottom of the kettle out getting as much wort as possible from the kettle post-boil. Obviously some very fine hop and grain bits still get through, but certainly not enough to cause an issue with your chiller, pumps or fittings if you properly backflush after brewing.
The other feature I like is that the hop strainer is very easy to clean. You just remove it from the bottom of the dip tube and clean it with some PBW then flush it with water and it easily removes all of the debris. The hose is flexible so you can flex it a bit and under some moving water to remove and trapped debris.

Kettle size brewbag – full hop utilization and you can squeeze the bag at the end (with gloves, of course).
I wonder if that will work with a bigger batch? I use a 20 gallon kettle. My hopstopper is around 10 years old and still works great.
Not a fan. I have their 5.5 gallon kettle. I bought this with it and it was an extra $50. The first time I used it I brewed a regular 3 gallon batch that only had about 1.5 oz hops total. After chilling, this thing plugged completely and no amount of stirring or trying to dislodge worked. I was not able to drain my kettle using the ball valve and I ended up having to syphon that batch. I took it off afterward and will never use it again. Seemed like a good idea. In reality, it was $50 wasted.
Is the above review based on whole hops or pellet hops?
How does it work with pellet hops?
It is based on pellet hops at normal hop rates. You might have a different experience with whole hops or very high levels of hops.
Does this kettle strainer also strain out the trub or just the hop debris? I’ve been putting my hop spider in the fermenter and transferring from the kettle into that. I find that the hops also act as a filter once they get deep enough in the spider and may even filter out some of the trub.
It can help with trub as well though no filter is 100%. I’ve found it works well for my style of brewing though.
