I finally feel that I am comfortable in properly reviewing the Blichmann HopRocket. I've used the HopRocket 10 times in brewing as a Hopback and 4 times as a Randel for serving. This might not seem like a lot, but some brewers only brew once every couple of months. Lucky, I am not one of them. Honestly I would of use the HopRocket more but it has its drawbacks. (I'll get to that in a second).
The HopRocket bills itself as a one two combo. Having the ability to tie into the serving line of finished beer like a Randel, that Dogfish Head made so famous. Or hooking into your brewing system to be used as a torpedo, like Sierra Nevada developed. Once on the market people started to tap into the HopRockets filtering abilty. Switching out the hops and placing rice, rice hulls or old hops as a filter media to catch some trub out of the wort during transferring.
The idea is simple, create a stainless steel tube with mesh shields on top and bottom then filling the enclosed area with hops/media of your choice. The HopRocket is clearly marked with flow direction arrows and a simple clamp ring for opening the bottom for cleaning and hop additions.
Lets start at the build quality. The thing is a beast. The proper construction is a big plus for me. The stainless is thick, more than my brew pot. The stainless fittings are also stout. In addition, they fit perfectly. Which is necessary when you are moving hot liquid or serving pressured beer for a extended amount of time.
As a Randel the HopRocket really shines. I personally do not have any issues pouring or serving once hooked up "In-line" with my kegging system. It adds a clean fresh hoppy bite. The additional hop aroma added during the pour is unattainable without this type of addition to the beer "out" line. Once the keg has kicked we start to run into problems. With a simple male thread on the top and another male thread on the side disconnecting the HopRocket is a mess. You have up to 4 ounces of spent hops leafs soaked in beer to dispose of. Without the addition of a stainless value you will destroy the inside of your keggor with streaming hop filled beer.

| HopRocket on my Black IPA |
For the HopRocket to be completely effective I need 2 stainless valves and some sort of disconnect(s) added it to my beerline. Now, I don't want to spend another 40+ bucks for a part that should of come with the original purchase. (I know that last statement might be a little harsh, but people should be warned at least.) I have made a promise to myself that I will not use the HopRocket as a Randel until I get the proper fittings to make disconnecting a simple affair.
Using the HopRocket as a Torpedo get interesting. I can not get the damn thing from not clogging. My system uses a March pump and since the 1st clog I have tried to develop a way to overcome this hurdle.
These solutions include:
- Running it backwards
- Using 80% Rice Hulls
- Dropped the total volume from 4 oz to 1oz of hops
- Changed the pressure on the output of the march pump
- Changed my set-up into a gravity feed system.

I understand Blichmann has an updated cone that will reduce some of the clogging issues which I do not have yet. So for now I will plan to have a bucket next to my HopRocket so when it clogs I can save some valuable liquid and put it back in my boil kettle.
Do I recommend buying this? Yes I do, even though you will pull your hair out every time you use it. The additional flavors added are worth the spilled beer, headaches and mess that this device causes.
UPDATE: Concern about parts.
Blichmann advertises the HopRocket as stainless steel. I understand the parts shown do not touch the beer in any way but after a big home brewery tear down and cleaning session I noticed this. (Above) the crack and rust.
I sent Blichmann the above pictures and a link to this blog. They stated, "they couldn't see the pictures and said this part should not be cleaned with the HopRocket." Honestly I pisses me off and I can not recommend this product. The clogging and corrosion are not worth the hassle.
Thoughts?
That is some textbook crevice corrosion. What did you use to clean the stainless steel?
ReplyDeleteA good buddy of mine said he thinks the rusted parts are stainless coated nickel. But for the cleaning I do PBW and starsan for everything. It is only on those parts. I contacted Blichmann today about the issue also.
DeleteI think you're going out of your way to be kind to Blichmann in this review. I haven't used the HopRocket, but the problems you mention sound like deal-breakers to me.
ReplyDeleteMarcos, I think you might be right. Mostly because I really wanted to love this product. And while it has great potential and build quality, it is just not ready for retail.
DeleteJon Blichmann followed up with my request and I sent over pictures, since that time about a month ago I have not heard from them at all.
I've been considering this device as strictly an inline filter, but yours is not the only bad review out there. Clogging is a definite deal-breaker for me since filtration would be my primary use. The rusted and cracked parts make it that much more imperative to avoid this item: a shame since another couple dollars worth of stainless would have fixed it. Thanks for your honest review.
ReplyDeleteHonestly, over the last couple weeks/months the Hoprocket has been resting next to my brewing equipment. Even switching the unit to Cam-locks for easy connecting hasn't made me brew with it more. I would stay away.
DeleteThanks for posting this. I was pretty tempted to get this thing... I'll just stick to whirlpool hop additions and dry hopping I guess. Also just followed you on ig @zacbdct.
ReplyDeleteCheers
Thanks for the comment. Its one of those things thats really cool to have but in use, completely impractical.
DeleteJust a FYI Stainless can rust. The lower grades, which I would expect in the clamp, are more prone to rust. I didn't see the crack but that would be a problem. Nickel would coast more than SS and it doesn't rust.
ReplyDeleteIt's probably 304 on the clamps and the stamped parts are probably 316. It really shouldn't rust that much but the PBW is an oxygen cleaner so if anything will get it to rust that will, and then hitting it with starsan which is an acid probably pushed it over the edge. Still if I were Blickman I would look at upgrading the material since lots of people are going to be treating it the same way.
Clogging would be a deal breaker and the lousy customer support (you are not the only one I have heard) is not at all what I look for in a company. They should have replaced the clamp, even if they thought it was your fault. THe rust could probably be avoided but a crack is a flaw that should be an instant replace.
