Absolutely! Or you could add priming sugar and set your spunding pressure to desired levels. Any excess CO2 created will be blown off.

Last night I turned the chiller back on to start dropping the temp to the extent I could. It was down a few degrees this morning.

Today I made up a gas transfer line and purged a keg using the gas from the Brewhemoth. That brought the pressure down to 5psi. I then harvested some yeast from the dump valve and cleaned up the valve to the extent I could. I bled the remaining pressure, opened the top and added gelatin and an ounce of Cascade for a modest dry hopping.

I sealed things back up and pressurized the fermentor to 30psi. I'll let this go for about a week and then keg. By then I hope my barbed triclamp fitting comes in, brewershardware had an item on backorder and that is holding up shipment. Its causing me to have to slow down my rapid-turnaround beer.

Would appreciate any tips so I don't clog my poly sulfone valve

Give it a shot and let us know how it goes. I did 15 gallons and it was a bit messy. Hence the reason I want a yeast collection system prior to my spunding setup. The keg idea seems great to grab the blow-off, but i am anxious to know how 15 gallons with fermcap works.

I'm guessing that 15gal in a 5.5gal fermentor is too much even with fermcap. Fermcap only seems to work for awhile anyway. I use it on my boils and I always have a generous krausen. Why do you want 15gal anyway? You still wouldn't get 15gal of finished beer. I think I'd just go with 11gal and have two full kegs per batch.

The thing I don't like about priming sugar is having to open the fermentor to the air to put it in. I had to do this to add my dry hops and gelatin, but I was conflicted about it. I'm going to give a strict no-air batch a try one of these times.

I've done many 15 gal batches in a sankey. That's the only size I do. I use 30 drops of fermcap S per batch.

I use a blow off tube for the first 48 hrs then put on the poly sulfone and crank it up. It works fantastic for me. I've tried the valve at the beginning and it gets plugged with proteins and hop particulate in the krausen. Then you've got trouble. It's a pain to keep taking it off and cleaning it so you don't have a bomb.

I've done a better job at the end of the boil with whirlpooling and letting the wort sit for 15 min before chilling. I don't get hardly any hops in the fermenter so maybe now I could get away with putting the valve on right away.

You guys have been talking so much about top cropping yeast that I've been thinking about connecting my blowoff tube to my filter and putting the valve on the other side to see how that goes. I've gotta read the yeast harvesting/washing wiki again before I try that.

I say go for it. More beer is better!!

How much beer do you get from a 15gal batch?

I have nearly exact setup as cmuench, except I do 10 gal. in sanke. I am having trouble getting to FG. I seem to get "close", close down the vavle and the FG doesn't get any lower. At what point are you close and should it be closed up to allow to finish and carbonate? Example, I start my oatmeal stout at 1.057 and expect FG 1.018. I have done this same recipe maybe 25 times and have never had trouble with carboys. I am getting to about 1.022 and closing it up. My finished after crash cooling, filtering, warming and rechilling is still 1.022?? What am I doing wrong??

**flananuts** · 12-29-2011, 08:13 PM

So I brewed my tiny nipples ipa based off the hard nipples iipa that just started force caring. I used fermcap in the boil and quite impressed since I boiled 14 gal. I decided to top up to 14 in the sanke and did add fermcap to the fermenter. My eff was spot on so I'm going to ferment under pressure at 1.076 and when I filter to keg, I'll split up the final gallon of water in the keg to hit 1.065 or so. I'll keep you posted on the process.

**flananuts** · 12-29-2011, 08:17 PM

I slowly ramp pressure over the course of the fermentation schedule and once I'm at about 3/4 finished I'm usually up around 8-10 psi and then I crank it up to 15psi for the remainder.

Okay heres some pictures of my setup. Sorry for the crappy phone pic quality.
