    Transferred a mosaic ipa to a keg tonight and trying to dry hop (3.5 oz in a muslin bag) in the keg on CO2. What is a standard protocol for this? Crank the co2 up and leave at room temp for a few days? Anything special I need to do with the CO2 for this or am I overthinking here.

    I am planning 2 days at ~70F while carbing up and then throw it the kegerator to finish carbing up for a few days. Anything obvious I can do to improve the tasty hoppiness of this beer while keg dry hopping?

    Nope, nothing really too special about it. Dry hopping is dry hopping. Force carb at your normal psi. Some don't do this (or like it) but I give my muslin bag a few squirts from my starsan bottle just to be safe.

    Cheers!

    You might consider leaving it out of the kegerator for a few more days...typically 5-7. The higher temperatures will aid with hop oil extraction.

    I hope those are whole cone hops you are using because pellets will find their way through most MUSLIN bags. Even whole cones could potentially lead to constipated pouring if you are not careful to keep everything inside the bag : (

    Good luck

    I do this w/ pellets all the time. I typically go for 3-4 days at room temp. I usually set psi to about 20-30, then bring it down once in the keezer. First couple pours are kinda murky, past that is fairly clear. If you want it super clear, keg jump it.

    I like to split up my dh hops into two bags when it gets over 2 ounces. No scientific proof, but two medium-sized lumps seems to allow for more exposure of hops to liquid and better oil absorption than one large clump. My target is low to mid 60s, although 70 will probably do just as well. As mentioned, I would try and give it at least 5 days at these intermediate temps before tossing in the keezer.

    I add no CO2 while dh'ing (other than burping the keg). When ready to pull the hops I jump the brew to another keg, the idea is to keep as many aroma molecules as possible. If you like to add finings (I do), this is the time. My pellets always leave behind some debris. After carbing (week+) it has pretty much settled and is poured off. Maybe an extra couple of days before it's completely clear.

    I consider all of this (dh'ing & carbing) as conditioning time . . . never in a big hurry as it will be improving every day of the process.

    R U using muslin or nylon bags? Big difference in my experience,

    I just got kegging equipment and my next ipa I want to dry hop in the keg. I have nylon hop bags as well as muslin bags. Do nylon bags prevent hop particles better than muslin bags?

    I use nylon paint bags . . . and they leak a bit. Never used a muslin, just my luck a "typo" would get me in real trouble.

    I soaked my bag and string in sanitizer for a few minutes before filling and adding to the keg.

    I have been reading some studies that suggest that 1-2 days gives you most (90%?) of the aroma you would get with a longer DH. Although they are in a bag so maybe 3-4 days at temp would be better.

    They are pellets... The bag is usspended in the keg. I expect some hop dust to make its way into the first few pours. Hope it clears up after that. I will let you know if it turns into an extreme failure.

    I am optimistic. This is my 4th iteration of my Mosiac IPA, but the first time I have dry hopped under CO2. I have been hearing good things about the outcome of this process and hoping to make a very good IPA even better.

    Nothing special at all. I've been dry hopping in the keg for years. Sanitize your hop bag, add to keg, then rack on top. I let my hops ride for the duration of the keg and have yet to get any grassy flavors due to oversaturation.

    Yes, nylon bags are mo betta, but the process of how cleanly you fill the bag is important also.

    You might get away with that once or twice, but eventually you will experience a clogged dip tube

    Let's call a muslin bag what it really is...a grain sock.

    For some reason, people get confused when you say "muslin"...I guess cotton/muslin sounds better than nylon, but not for dryhopping.

    Glad I stopped in this thread. I was planning on adding 2 oz of pellets in a suspended muslin bag tonight. Would double bagging the hops work, or should I use a 1 gal paint strainer bag?

    Nylon's superiority is due to smaller mesh size or reusability?

    Is a 'cleanly' filled bag a bag that has all of the hops on the inside of the bag?

    I've used fine nylon bags, and muslin. Nylon does work better, but if you just suspend the bag high enough that after the first 3 pints it is no longer submerged...then it clears pretty quickly.

    I don't recall how fine the mesh is on those paint strainer bags.

    I haven't come across this, but I'd be surprised that a packed hop bag would release most of the oils in 2 days. My personal experience has been about 5 days being the sweet spot, but YMMV.

    Good point, Nylon paint bags.

    The paint strainer bags are pretty fine mesh, I'll probably use one of them this time and see how it goes.

    These are the one's I've been using to strain my wort after cooling:
