This is what I do and never had a problem with blowoff. I have a fair amount of headspace though. I have a 15 gallon corny for 11 gallon batches and use a 10 gallon corny for the occasional 7 gallon batch. If I were running tight on space, I might consider other options I suppose.
A conical fermenter now seems so …practical.
After 3 years of no trouble with my 15 gallon corny, I can’t imagine something much more practical. Large, stainless, fits in chest freezer, costs under $300, liquid and gas ports included.
Only downside is that it’s heavy when it’s full. But there are easy ways to get around that hurdle.
In a perfect world, a 27 gallon heated and cooled conical next to the brew stand would be wonderful. But for the price, the big keg is a pretty sweet deal.
Where do you all score these giant cornies?
Edited to add: never mind I found some on ebay.
Got mine as a second from kegglebrewing.com
Chico Company has them as well.
Never any clogging here.
$200 for 10gal or $300 for 15gal isn’t bad considering you already have an opening for cleaning and gas/liquid QDs for easy maneuvering of liquids and pressurized fermentation and/or carbonation. A similarly sized conical is quite a bit more expensive. Seems like a 15gal would be cheapest since you can brew an 11gal batch and fill two carboys.
Just a quick heads up for anyone considering the 15 gallon corny to ferment. They are heavy when full. My chest freezer required a 12" collar to accomodate the 15 gallon corny and wheels to move it around since I put the corny into it empty and then pump the wort to it.
Once you get past that, it really has been a great fermentation vessel for the money. Been using it for about two-and-a-half years and have been very happy with it.
Have been fermenting in a 10 gallon keg for quite a while. It works great! I use a cask widge flow when transferring to reduce/eliminate sediment pickup all the while not wasting any beer.
Awesome idea! I bought one to try for serving, but using it in the corny fermenter is genius! Just pop a little gas-in diptube on the beer-out side and push the silicone hose on?
Pretty much. I’ve got a write of it here…
It works really, really well.
Thanks. Did you end up cutting off some of the silicone tubing?
Not for a 10 gallon keg, the stock tubing is a perfect length for that. The tubing does need to be trimmed off for using in a 5 gallon keg.
