Keg fermenting

[redrocker652002]

OK, so my plan is to get my ferm fridge ready to go for my next brew to ferment in a keg. My question is, should it have a dry hop component, how would I hook up the tubing? Is it gas post on the ferm keg to gas post on the dry hop keg, then blowoff tube to a bottle of starsan? Assuming I have floating dip tubes on each. Then, once done, I hook up the liquid on the dry hop keg to the liquid on the serving keg, add the CO2 to the gas post of the dry hop keg and transfer? I know I can probably look it all up on Youtube, but thought I would ask just for the heck of it.

Edit; I am going to post at AHA just to see what some of those folks say. In an effort of full transparency, I want to get as much info as I can. Thanks

Although I have not done it, I hear people talking about putting a SS washer or something in your hop bag and keeping it on the lid with a rare earth magnet. When it's time to hop, pull the magnet. Seems like a decent trick.

A corny keg lid with a 1 1/2"tri-clamp

I was told by someone about these... Didn't get one yet but probably will sometime to do faster keg transfers or hop drop.

I am doing a hop drop for a conical with 1 1/2" tri-clamp port. All items below are for 1 1/2" tri-clamp connections.
1) ball valve
2) sight glass (or ss tube)
3) adapter 2" to 1 1/2 triclamp reducer

4) (this is a 2" tri-clamp accessory). corny gas post and PRV

Ball/or butterfly valve is closed initially.
Add hops to sight glass. Hook up CO2 and purge chamber. Add a little pressure if needed to match fermenter pressure. Just a few psi more ... So hops get sucked into fermenter under pressure and gravity.
Open ball valve to let the hops in. Close ball valve to keep out oxygen .

Not using kegs, but I believe @Dgallo some something similar with two Fermonster fermenters with gas posts.

I am curious about this myself. I like the idea of keg fermenting, but have only done it for beers that were not dry hopped. I envision using a 6.5 gal keg and a lid with a TC port...but that is a good $200 and I already have too much equipment around!

I started with just the 6.5 gal keg... And LOVED IT. STILL DO. (It was about $150 several months ago).

And put together a KegLand PRV spunding, gauge thing attached to a gas post. The keg came with a floating beer dip tube thingamabob .
Very happy how the beers came out, especially the cold temp fermenting varieties (lager, pilsner)

If you want to use 3 kegs for one brew, yes, you can do it like that. I've heard recently it's good to dry hop while the beer is off the yeast so I'm all for having a middle dry hop keg if you want.

You'll want ferm keg liquid post to secondary keg liquid post. Secondary keg gas post should either have a spunding valve or a blow off tube to a bottle of star san. That will purge the secondary keg with CO2 from primary fermentation. You could add your dry hop to the secondary keg in the middle of fermentation and because it's being purged with O2 from fermentation, the hops will stay fresh.

Once, you are ready to move the liquid from your secondary 'dry hop' keg to a serving keg, yes.. liquid post to liquid post while pumping CO2 into the gas post of the dry hop keg.

I fermented in 6 g kegs. My eventual standard was for the first 2-3 days, depending on yeast, just let it rage into an airlock. For an airlock i had some tube on a gas ball lock running to a half full of star san 20oz soda bottle. The soda bottle was bungeed to the side of the fermenter.

After most of the fermentation was done, i’d then dry hop and spund to about 5 psi

 

[redrocker652002]

Great suggestions folks thank you all for taking the time. This weekend I think I am going to try and get the collar in place and secured. I have about 10 to 12 kegs, half of which I have tested and hold pressure. If this works then no more bottling and I can keep kegs in my ferm fridge at lower temps once fermentation is done and they will be at the ready. Awesome stuff for sure.

 

[Willy]

Just got 4 nice used cornys from beverage element for about $38/each. Very well cleaned (industrial clean!). Currently doing a PBW & star San ... & Will put them under pressure to finish the... Ready to keg em status.

Btw... The used CF-10 is looking fine! Cleaned and cleaned... And added some bling. (2 sight glass add-ons... Cheapo from Amazon) And the newer top with (3) 1 1/2" tri-clamp ports .

I started a similar thread a while back, you may want to skim through it. Lots of good tips there.

I currently have an amber ale fermenting in a corny keg, but it's a smaller batch, and I'm not dry hopping it, so it's easy. Just ferment, cold crash, and transfer under pressure.

does that refer to a chest freezer or is this the 'dorm-fridge'? ...If you have the height for a dry-hopper, wether DIY or Hop-Bong https://www.brewhardware.com/product_p/hopbongkit15.htm and the lid like @Willy mentioned (also available @ https://www.brewhardware.com/product_p/cornylidtc.htm ) You might want to include that in you mod so you can skip the extra keg.

Read thru most of the posts. Seems I can connect a line from the gas port of the ferm keg to liquid port of the dry hop keg. Use the CO2 gasses from the fermentation to purge my dry hop keg. Once fermentation is done, run a line from the liquid post of the ferm keg to the liquid post of the dry hop keg, attach CO2 to the gas post of the ferm keg and transfer. Once dry hop is done, do the same from the dry hop keg to the serving keg and boom, no O2 exposure and hopefully successful beer. LOL.

This is a dorm fridge. I am going to try it using two kegs and just run tubing to see if it works. Those are good ideas though and once I get my process down I will check them out. Height is a bit limited in the fridge so those items might not work right now.

So, the Corny Keg Lid With TC Port and the Hop Bong Dry Hopper Kit - 1.5" TC plus the Butterfly valve all from Brew Hardware are all I need to have a hop bong atop a normal 5 gallon ball lock corny keg? If so I see an order going in soon.

I've done the three keg setup. Add the serving keg in the chain and fermentation gas from the first keg will purge the other two.

I just think about space and maximum keg count...have you ever considered an inline Randall?

I had bought one of those cartridge filters a few years back with a 5-micron paper filter to try out filtering my beer and it was more trouble than it was worth, however; I still have the filter housing and I'll be repurposing it to a Randall to use with a 12V RV water pump that I've swaged 1/4"(6.35mm)ID EVABarrier line on to the 3/8" barbs when I need to make an IPA.

That is a pretty cool little do dad. LOL. Right now, I have everything I need and it isn't costing me anything but time. So, with that said, I am going to try and keep it rather simple first and if it works out, then start thinking of the "cool" stuff. Thanks for the info.

I would do just that, but space in the ferm fridge is limited to two kegs with the 2x6 collar. Plus, my kegerator only fits one Torpedo keg, so I am very limited (1) to the kegs I can fit in there. My thought is, if I still have beer in my serving keg, I can keep the next beer in the ferm keg and time it so that the dry hop and serving kegs are ready to go within 4 or 5 days. Or, just have a storage keg at the ready to store the completed beer in the ferm fridge at serving temp. I think the options will open up as I get to doing this and trying it.

Honestly I'd like to know too! I've been considering a hop-bong for the sanke fermenters that sit on my basement floor, but I do have another fridge on my very long-term fantasy shopping list (when I can find the space for it )

With the butterfly valve before the hop bong, the hop bong can be taken off after dropping the hops and then a blank can replace it.

The blank is an extra good idea if it'll sit for long. The seals in the butterfly valves tend to be silicone. It also keeps the valve innards clean.

I don't have one of these lids, but if I did, I'd leave a TC blank on the top of the valve, and leave the valve cracked during primary to make sure the top of the valve purges.

Yep. If your keg doesn't have one, I'd also add a floating dip tube with a filter on the end to that list. This will keep the hop debris from clogging your disconnects during a transfer to your serving keg, or if you're serving from the primary keg, if you're dry hopping commando style.

Thanks, I already have a couple fdt’s, so I have that covered.

On another note, I think I would get the one from Bobby M. The one linked to Amazon doesn't seem to have favorable reviews. Plus Bobby's is $2 cheaper.

Yep. If/when I pull the trigger I'll definitely go through Bobby.

Paging @Bobby_M Getting closer to pulling the trigger on this Brew Hardware setup to dry hop in a 5 gallon corny keg, but I'm leaning towards spending a little more and going with the 2" hop bong setup rather than the 1.5" if it can work. Reason being is the 2" would accommodate far more hops at a time on those massive dry hop additions needed for neipa's. If my thinking is correct I'd have to add the 2" to 1.5" reducer to make it work with a corny, but I'm wondering if reducing the path would impede or even prevent the hops from dropping. Also, going this route, would the reducer go above or below the butterfly valve?

I put one together that is a hybrid of 1 1/2" and 2" triclamp.
Top to bottom
2" PRV and gas post
2" - 1" long, ss tube
2" to 1 1 1/2" ss reducer
1 1/2" sight glass
1 1/2" butterfly valve

Had I known about Brewhardware I would have just gotten Bobby's solution.

 

[Bobby_M]

I think we ought to pause and see if hops will drop into the slightly smaller than 1.5" tubing going into the lid. I know that as long as the hops drop through a 2" butterfly, they have no problem reducing down to 1.5" through the concentric.
