HopRocket Randall Foam & Stopped
« on: February 06, 2012, 02:09:49 PM »
I hooked up my HopRocket in-line on my draft system last night.  At first it foamed like crazy then just stopped pouring.

I am going to disassemble and see why its blocked but I wondered if anyone had any tips for foam-free pouring when running draft beer thru 3 oz of hops.
Cheers,

Timmy

I would think you would have to presurize the randall to the same presure as the keg. don't know if that is possible though.

I don't think it is is possible to pour foam free through a randall.  Pressurizing it might help. Maybe.

The 1st few pints are foamier as it's purging the air (and co2 if you purged the rocket prior to filling). The hoprocket should be in the fridge the same temp as the beer to minimize foaming. It can hold up to 40 psi.

No need to re-invent the wheel.  Look at page 2 for the parts list. 
Looks like it'd be easier to just ask DFH to build you one at cost (but, according to their website, they're not building any right now).

The key is the faucet which supplies the necessary "resistance" to allow the carbon dioxide gas (and hop aromas/foam) to reenter the beer prior to pouring

Interesting....as of now its working 5X5.  Jury is still out if I like Cascade-infused American Brown Ale....despite my love for hops, this may be a bit too much.  More to follow.  Perlick also makes an adjustable flow faucet.

+1

Chilling the hop rocket is required in an effort to minimize foaming.

Check out this video by John Blichmann. Start at 6 min in to see the demo as a randall.

I've watched the video.  I think you just need to let the hops get soaked and cold.

What's the best hop to "Randall" an American Brown Ale with?

I would use Centennial for an American Brown.

Our randall is not a hop rocket, so I can not elaborate on that product, but we use the "traditional" water filter housing technique but with a second chamber after the hop infuser. This cuts down on foaming significantly. OTOH if you are only pouring a couple pints at a time it may waste a lot of beer.

Also if it is clogging you might have it packed too full. Don't pack them in there. Just fill it and leave them slightly loose. The beer will cause the hops to swell significantly. Also be sure you didn't get any hops "dust" on any seals or inside the "filter" housing.

I think you are right.  I am using Cascade and do not like it as much as I expected.

Centennial is also known as "Super Cascade," so I wonder if you'd really like it if you're not wild about cascade...

Amarillo makes a mean American Brown!

I actually own a hop rocket and used it with 2 oz amarillo during my whirlpool it was fantastic.

Any pictures? The second chamber doesn't have anything in it? I like some of the presentation aspects of Randalls but hate the waste introduced by the insane amount of foaming that seems inevitable with this setup since you're filtering carbonated beer through a billion tiny nucleation sites.

Have you seen the discussion on the 'hop squasher'? just put some hops in a french press and add beer. filter and drink. still foaming issues but a lot less waste I would think. Havn't tried it myself but it seems like a good idea!
