Product Details
The HopRocket™ is an incredibly innovative, feature packed hop infusing tool! Not only can it be used as a hopback, it doubles as an in-line hop infuser (Randalizer) for your beer dispensing system and TRIPLES as an in-line filter! Definitely cool, and clearly Blichmann - let the HopRocket™ put your hop aroma into orbit!!

Unlike competitive units made from simple kitchen-ware fitted with a basic false bottom, the HopRocket™ has been designed from the ground up as a purpose-built, heavy duty, hopback and hop infuser. This clean sheet approach means truly superior performance and features:
• Pressure tight - up to 40 PSI operation!
• Holds up to 3 oz of whole hops.
• 100% stainless construction & silicone seals
• No need to monitor wort level - will never overflow and spill like competitive units!
• Fully enclosed system from brew pot to fermentor means no volatile hop aromas are lost!
• Inlet at the bottom allows air to automatically purge to reduce hot-side aeration
• Fine filter with wiper seal sends very clear wort to your fermentor.
• Coarse filter and cone bottom inlet prevents wort channeling and backup for even hop utilization
• Works on gravity systems and with pumps (about 4ft (1M) of static head is recommended for best gravity performance)
• Doubles as an awesome hop infuser (Randalizer) for your dispensing system or kegerator
• 1/2" NPT connections are easy to adapt to. The HopRocket
does not include barbed fittings. • Measures 10" in height by 6.5" in width.
• Now features a High Flow Insert - allows higher flow rates and improves plug resistance. 

Note: Not for use with pellet hops, only whole leaf hops.

Pairs well with our Draft Brewer keg systems for use as a fresh hop infuser in your kegerator or keezer.

Hard to use as an infuser.
So, bought brass fittings to connect everything up to work as a hop infuser between my keg and my kegerator tap. Concept is great, but couldn't get the fitting to seal properely, so a lot of leakage and air voids causing a lot of foaming issues! Removed it and hooked up the keg the regular way. Ordered the new fittings that are supposedly made for it specifically, but I have read mixed reviews on them, so we will see. I will try again on my next batch, but I am starting to think it is just easier and foolproof to "dry hop" the keg.

Triple Threat - HopRocket
We used this bad boy to infuse our wort with fresh hop aroma and flavour on the way to the primary. Then, we used it to double down on hoppines ahead of the tap as a randalizer. WooHoo! It can be used as a filter, but we have not employed it this way yet. This piece of equipment is a homebrewer's Swiss Army Knife. Gitchersef one!

Real-time, in-line hop infuser that is really fun!
I haven't used this as a filter yet, but since I grow my own hops and had a good crop this year, I wanted to try hooking the rocket up to one of my keg lines after packing it full of fresh-picked hops. What a crowd pleaser! My first attempt was to attach it to a keg of an American Amber Ale of mine that was just "so-so", and I used 3 oz of fresh-picked Chinook in the rocket and it came out as an instant IPA that was awesome! For sure, use a mesh bag to put the hops in before you clamp it down. Since then, I have also used it to infuse a batch of Kolsch, too, with similar results. Clean up is easy, but beware when you get ready to disassemble it: you will have about a litre of brew inside the rocket that will want to go follow gravity as soon as you disconnect your lines. So have a buddy and an empty pitcher handy to catch these final runnings as they drain out. You won't want to waste a drop!

Achieves the Next Hop Level
I have tried various methods of dry hopping, varying the hop type, pellets vs leaf, amounts, time in the wort, with and without bags, etc. I have never been able to get my IPAs and DIPAs to the desired level of hoppiness. The HopRocket has allowed me to get to that desired next level of Hoppiness! I am impressed with the results.I use a gravity system to move my beer. After reading some of the previous reviews, I have raised my wort kettle once I have completed the boil. The HopRocket is next inline, placed on a small ladder. The wort leaves the HopRocket and moves through the Therminator (another great product) and then proceeds to the carboy. One problem I found on my first brewing session: I typically tilt my wort kettle towards the end of my wort draining and my wife called and I did not tilt on time and I ended up getting air into the Hop Rocket. that stopped the flow and I could not get it going again. On my subsequent brewing sessions, I tilted when I needed and the flow continued until my wort kettle was completely drained to the point I desired. The HopRocket will still have a lot of hot wort in it at this point: I disconnect the infeed tube while holding the HopRocket upside down to drain the wort trapped in the HopRocket into the Therminator. Less loss this way, but be cautious, the HopRocket will get hot! I then lift up my Therminator to drain the wort out of it and into my carboy. There will still be some loss of wort trapped in the hop leaves inside the HopRocket, so plan accordingly. I typically add some extra grain to my recipes to account for various loss and balance that against my starter volume. I have been very happy with my HopRocket and have even used it in lagers: I'm not trying to turn them into super-hoppy beers, but I do get some additional hop flavor into the beer that is appropriate for the style.

Awesome! Free Upgrade!
So, I've used this several times now and am getting the hang of it. Without a doubt I get clearer wort, better aroma, and enhanced flavor when pumping between my Boilermaker and Therminator after boil. Now, I think I'm going to get a second one and circulate wort through it during the boil for my bittering hops. Also as to my earlier concern, on the Blichmann website I see they modified the fine screen for higher flow rates. Could possibly help with smaller volumes of hops? Anyhow, free upgrade! Get it while it lasts!

Actually worth the $$
I went back and forth on this purchase... i use an immersion chiller and don't have a pump, so i was worried that i wouldn't get enough flow out of the kettle and that the colder wort wouldn't pick up the aroma well. My fears proved unfounded. I brewed a batch of pale ale yesterday and the Hop Rocket didn't dissapoint. I lifted the kettle up onto my tool chest so that the base of the kettle was about 4.5 feet off the ground. The Hop Rocket sat on the ground and the output flowed into a 6.5 gallon fermenter (also on the ground). The flow rate was fine - probably about 1 gallon per minute. More importantly the Rocket filtered out the trub in the kettle so well that i could actually drain it fully. I've never seen so little hop sediment in the primary, especially considering I used 6 oz of hops for this 5 gallon batch. Even when the wort going into the Rocket was dark green with trub the output was clear. Amazing. The aroma of the wort in the primary is impressive too; even if i could get more aroma out of a hot extraction i'm happy with what this product did for me as is. A few other notes for potential buyers: I installed 1/2" NPT to 1/2" nipple fittings ($2.99 ea) for the output and input connections. My existing hi temp hoses slipped over the nipples for a no-leak, low cost connection to the kettle and fermenter. You might need something a little more hi tech (polysulfone disconnects, or at least hose clamps over the nipples) if you're going to pump the wort through the Rocket.

I had some issues....BUT
I used my HR once so far as a filter before my Therminator. I filled it with 5oz of hops, which is the max recommended. Using a March pump I was unable to get much flow at all. After about 30 minutes only 4 gallons of my 12 gallon batch managed to seep though the HR. At that point I said the hell with it and took the HR out of the loop somewhat disappointed.I just tapped the brew this past weekend and the hop aroma is just - and I say this with a staunch record of heterosexuality - FABULOUS.The only thing I would change is maybe go with 4oz max. Or use a more powerful pump.Looking forward to using it again.

Pretty Fing cool
One of the welds on my unit was very questionable but held. I almost returned it. Let me tell ya if you have a Blinchmann boil pot with the hop blocker or not and or run through a plate chiller you really need one of these. I love the aroma it gives to my beer, but the real advantage of owning one of these is it filters out the hot break and hops like a champ. I noticed about 85-90% less shisnit in my plate chiller when back flushing. I have used bags and all kinds of things to try and filter out my hot wort before it hits my plate chiller. This is the ticket. If you think you have a good beer use this bad boy and it will deffinately take it up another notch. It may be pricey but it's worth its weight in gold enough said.

Worked completely as shown in video
Brewed an IPA with the hop rocket filling the HR with 3oz of hops and it worked awesome. I used a march pump and a CF chiller. The flow rate was better than I thought it would be, and the hops filltered out almost all of the break materail. I have never had such a small and clean looking yeast cake in the fermentor, almost no break material all yeast. I have yet to keg the beer, but the smell is much hoppier than the last time i made the same recipe, but this time I used less hops this time moving the flame out hops to the HR. I think in the end this product is actually going to same me money on hops since I make alot of IPAs. Can't wait to use this HR as a randal.

I would like to use this unit as a filter between my boil kettle and a plate chiller without adding any additional hop flavor. Is there another filter media that can be used that will not alter the flavor of the beer ?

BEST ANSWER: The hop rocket makes a great inline filter. The manufacturer recommends filling it with 3 oz of rice hulls to filter wort.
What is the expected ibu extraction rate using a hop rocket.
T S on Jan 19, 2016

I'm not sure that is very easily calculable. Since the hop rocket isn't used while the wort is boiling and bitterness extracted would be very minimal and would greatly depend upon the alpha acid content of the hop being used. It is mostly used to extract flavor and aroma from hops and unless your recirculate through the hops I don't think the contact time would be long enough to extract much bitterness at all.
