Title: Dry Hopping in a corny keg
Post by: bretniday on January 05, 2013, 12:43:41 AM
Hello all, Im new to the AHA and all grain brewing for that matter. My question is, Im looking to do a dry Hop on a Lagunitas IPA clone and have never done this before. Is it safe to rack off to my keg hang the hops and purge any air from the keg off with CO2? Is this a common practice when dry hopping? what are some of your favorite methods of dry hopping?

Yes - very common in fact - I typically put a couple ounces in the hop bag tie it off with some Teflon tape and snake it between the oring gasket and the lid.  Leave it long enough that it will pull the hops off midway through consumption.

I do this with unwaxed/unflavored dental floss tied around a hop bag.  I only use whole leaf hops now, pellets always make such a mess.

Thanks guys for the feedback. Never thought of hanging the hop bag in that fashion, I was contemplating tacking a stainless hook on the inside of the lid. had seen it done before, but your idea is much simpler in the time frame im working with.
   So do you thin just set your carb to serve pressure and thats that? leaving the hops dangle till the keg runs dry?

Yeah - sometimes I do and other times I pull them.  Lately I've been blasting them with 3oz/5gal in primary so I haven't needed to do so in the keg, but it's all up to you!

Some lids have a recessed well for the pressure relief valve, you can us a SS hose clamp to fasten the bag/floss there.

Or the plumbers teflon tape works well under the o-ring.

Having tried many different methods, including racking to Brite tank/'secondary' then dry hopping, hopping in primary after fermentation, hoppng in keg, I have to say my favorite method so far is tasty mcd's method where you add a lot of dry hops (2-3 oz for an apa, 4-5 for an IPA) at the tail end of fermentation in the primary for 2-3 weeks (I don't 'secondary' anymore). I find that the grassy/vegetal flavors are driven off but the good volatile oils remain.  Add  them when the bubbles slow to about every 5 seconds.

So having never done this before my big concern was oxidation of the beer when dry hopping into my primary witch is a carboy. The post primary hopping is the style im most interested in trying out, without racking off into a secondary. So do you just toss them in and thats that? Thanks for the reply mpietropaoli

Tasty actually says in the podcast on IIPAs that it drives off any potential oxygen, to which hoppy styles are particularly vulnerable.  I use a 45cent muslin bag and weight (sanitized shot/heavy glass).  Some dispute whether the weight is necessary.  I've had good results w weight and no weight.  Adding while fermentation is still active is what supposedly ensures that the oxygen is removed from the hops and the beer.

I want to do this method with coffee beans for a stout or porter, just to add that extra aroma/flavor.

My preferred method is to tuck a hop sock containing whole hops between the out-tube and the wall of the corny about 1/3 from the top of the keg.

I know some pros who do this, but they pull the beans or serve the beer after 3 days.  Any longer and they don't like the flavor profile.

I'm scared of dry hopping in a corny with pellets - has anyone been brave enough to work up a solution for that?

I'm concerned that the little particles, even in a bag, will clog the poppets.

In a fine mesh bag, I wouldn't think it would be a problem. But I haven't done it, so I guess I can't say for sure.

if you use a muslin bag, its going to be a problem - if you use a nylon bag, I don't think it is going to be an issue.

Nylon stockings should work well without letting any hop debris through.

I've used pellets in the nylon bags with no issues. When using the fine mesh bags nothing should escape that would cause a clog. Of course there are always variables where someone else may have different results.

It takes a lot to clog a poppet. For example I ferment in corny kegs and use the gas disconnects for the blowoff tubes. Even when there is a lot of blowoff there is never a fatal clog. When pumping out, sometimes there is a lot of yeast slurry before the beer flows, but it still flows.

Avoid the muslin bags and other stretchy larger mesh bags.I'm sure they must be good for grains or something but useless for anything I've used them for. Nylon bags just clean up with the garden hose or in the sink and can last for a long time if cared for. They are also good in the boil for containing pellets when larger loads are needed that can clog the plumbing :-)

at least you have the benefit of not getting funny looks when going to the store to buy them :)

BTW, if using pellets to dryhop, I find the nylon 'socks' for paint sprayer pickup tubess are the perfect size and can be reused multiple times. :

I have found them much cheaper at SherwinWilliams, FYI

Even better. I only have pellets (storage space limits my hop hoard otherwise) and these seem like they might last a bit longer than a pair of knee-highs.

I must shop at a freaky CVS then, because they never bat an eye when I buy a box of nylons with a pack of zip-ties.

I worked the register at a pharmacy during high school - few things interested me less than what people were buying.

I recall a few specific combinations that made me take notice. Condoms, bananas, and a single roll of toilet paper...

That was you the night of my high school graduation? ;)

I have a whole treasure trove of stories from my retail pharmacy days...
