  • Dry Hopping Slurry Method

    Hi All,
    Starting at a new brewery and I don't have a port on the top of my FV's to dump my dry hop addition into. Is anybody familiar with breaking pellet hops down into a slurry and injecting them into the tank ? I would like to avoid duming the hops into the manway and racking the beer onto them.

    Can you use a funnel thru the prv port on top? Call a local stainless welder to come weld in a TC ferrule to the dome of your FV?

      If you don't have a handy source of deaerated water, this probably isn't a great idea…

        Unfortunately I don't have PRV's on the tops of my tanks they are attached to the CIP arm.
        I was thinking of using beer to create the slurry and injecting it via yeast brink. Really looking for a good liquid to hops ratio.

          How big are your batches and how big is your brink?

            I second the issue with needed deaerated water.

            How much weight of hops are we talking about here? I dry hop (11-22#) in through the PRV using a 'nalgene' (white labs yeast 2L bottle) with the bottom cut out to make it into a funnel. the threaded top fits snuggly into a 2" TC ferrule.

            what are your other plans for dry hopping other than through the manway or slurry?

              This sounds like what they do at Stone (among others). They have a dedicated slurry vessel, but they use beer to make the slurry then inject it w/ CO2 pressure.

              Just fill up the brink with as much beer as you can. If you find the slurry is too thick, you may have to split the dry hops and repeat the process. The 'ratio' will be dependent upon your brink/tank sizes, dryhopping rate, port/line diameter, etc.

              I would fill the brink from the bottom or from a racking arm to get good mixing. Then transfer back into the tank via the racking arm (pointed up). Use the largest diameter ports/valves/hose that you can.

              Make sure you purge the brink and hoses before transferring beer.

              Let us know how it works out!

                Success !!

                Thought I would drop a line and let everyone know how I made out.
                I used a standard GW kent 15.5 gal keg converted to a yeast brink.

                -Fill with perisan and pack hoses from brink, let hoses sit and sanitize, push all perisan out of brink with CO2
                add dry hops to brink
                -purge brink of O2 (no beer at this point) by pushing CO2 in through bottom port of brink and out top port
                -Connect hose to tank
                -backfill half of brink with beer while shaking
                -allow beer/ hop mixture to sit for 5-10 min shaking occasionally
                -fill brink to top

                -push beer/ hop slurry back into tank (I have needed to use high pressure 40-50PSI)

                -Repeat backfill/ injection (once has worked for me)

                The kent yeast brink seems to work well for 10BBL batches. Im using 10lb/BBL for my dry hop.

                  10 lbs per bbl?? You mean 10lbs per 10bbl?

                  Looks like you found a solution. How long are you finding that the beer takes to settle? Do you rouse it up a bit after transferring all the slurry? You probably get a nice hop pile in the cone/dish of the tank. you able to rack from above that?

                    I usually inject my slurry and then rouse right after. I rouse the hops again 2 days later then cold crash the beer 2 days after that (for a 4 day total dry hop period). I usually have a pretty good pile of hops left over afterward (if anyone has an idea for using these let me know !) and Im getting good clarity using biofine and a GW Kent strainer.

                      Reviving an old thread. Has anyone previously dumping dry hops through a DH port/PRV port on top switched to this method? If so, what improvement have you seen? I am currently just dumping the hops thru the hop port on top. But if this method is better/quicker/less hops to gain the same or better aroma I am interested in trying it out.

                        I'm getting ready to start dosing this way. I'll let everyone know how it works out.

                          i too am interested in hearing how this method compares to dumping through the top.

                            Works for me

                            I tried this the other day on a second DH addition on a New England IPA. I set up a block and bleed on the FV racking arm, ran a 5' 1.5" line from the brink to the block and bleed, filled up the brink with sani and pushed out the block and bleed with co2, closed off the valve at the bottom of the brink, vented brink, added hops, purged with co2 several times, applied head pressure to FV while venting brink to fill with beer (fills very fast!). I let this sit for 45 minutes or so to "dissolve" the pellets, shaking occasionally. I then pushed the slurry into the FV. I had to refill the brink several times to get all the hops out.

                            I now have a racking arm for my brink from Deutsche. I'm wondering how well this would work to help empty out in less refill cycles or if it would be a clogged nightmare. I will also switch to a 10' 1" line from brink to block and bleed next time as it's a royal pain trying to maneuver the brink around with a short stiff hose on it.

                            I was thoroughly impressed with the results of slurry dry hopping. It seemed to work instantly. No floating dry hop raft on top of the FV, no churning with CO2 to get them to suspend into the beer. Aroma on the finished beer was great.

                              Andrew_FSBC - would you be able to describe what a "block and bleed" assembly is, I haven't heard that term before. Is it tees on each end of the line that are valved off on all ends to allow purging of the line with CO2? This is what we have used in similar setups for hop recirculation where we need to push sani out of a line with CO2 before introducing beer from a tank (for hop recirc, transfers, etc).

                              Also, would you be able to speak to the quantity of hops you are able to push in per brink? We end up adding 30 to 40lbs in a 30bbl tank - would this take most of a shift to cycle through the brink with the slurry method?

                              Thanks for any clarification you can offer. I am intrigued by slurry dry-hopping. We have just added hops to the DH ports on top of our FV and recirc'd the hops on day 3 before crashing on day 4. Great aroma, good settling of trub/hops but kind of a pain/safety concern as we look toward adding a couple 60bbl FV's in the near future.

                              Cheers,
                              Tom
