Hi all,
We have a custom fabricated hop back. It is pressurizable, with capacity of about 200 litres.
It has a dome shaped removable lid, with gas fitting, plus 1 1/2 inch triclover fitting.
The bottom is dome shaped, with a 1 1/2 inch triclover fitting.
Inside the hop back is a false bottom with a milled plate, with holes approx. 3mm.
Our process is to fill the hop back with about 8kg (16lbs) hop flowers, purge the tank with CO2, then fill from the bottom with hot wort to let steep for about 5-10 minutes. We then reconnect the piping so that we fill from the top, and draw from the bottom through the heat exchanger into the fermenter.
We whirlpool for 5 minutes via pump, and then let motion do the rest for about 15 minutes, so about 20 minutes all up.
We try and keep total transfer under an hour from kettle to FV.
The flowers are hand rolled before going into the hop back, but that's about it.
Now, I'm sure I've given you heaps of useless info, but any advice would be great, because when we pull the hop back apart, there still seems to be so much lupulin/resin in the flowers, it seem like we're not doing something correctly.
Do any of you "mouli" or shred the hop flowers?
Any tips would be great!
Thanks in advance!
Cheers,
Matt
