I built one out of a water filter. I mount it upside down so the foam is away from the outlet valve. I just cut a piece of pvc to fit in place of the filter, then slotted it. I left the bottom 2/3 unslotted to force the beer to flow up through the hops first. I have not seen a two chambered one, but I imagine it is for foam settling - there is a lot.
The second chamber is for foam settling, as Tom said. You can also put additional spices/fruits/etc. in second chamber. I’ve done hops in first chamber and crushed grapefruit in second to great success.
Can anyone explain why I would spend $288.00 on a Randall to infuse my beers with stuff (made of plastic, nonetheless) when I could buy the multipurpose Blichmann HopRocket (made of stainless) for $125?
That is, in this theoretical world where I need to spend more money on this hobby. :
I don’t disagree with you, but the Dogfish Randall is made to be showy while the hoprocket is more utilitarian. I am surprised that they have not created a version out of stainless and pyrex.
Because Randall’s are mostly just a gimmick, and people like to see whatever you are loading in the Randall chamber. and you can’t see jack behind a stainless steel hop rocket Randall. Just sayin
Well, yeah. They do change the character of the beer. But from a commercial standpoint I can assure you that there is a massive dose of novelty going on here. For instance, a Randall filled with sour patch kids definitely changes the character of the beer. But not in a good wAy. People try it because if the novelty.
