This product developed by Yakima Chief and available at most homebrew suppliers also comes as a fine powder, making absorption even more direct than the pellet hops. Producers of Cryo Hops suggest that brewers use just 50 percent of the amount of Cryo Hops that they would use of pellet hops. With hops in hand, it is time to decide when to add them to the wort or beer to achieve the desired flavor impact and beer appearance. First, when hops are added while yeast is actively fermenting, an interaction between hop polyphenols and protein occurs, which causes a permanent haze in the beer.
Another reaction called biotransformation also occurs. This is still being studied by brewing scientists and chemists , but the premise of biotransformation is that when hop compounds are exposed to active fermentation a transformation occurs.
The transformation results in altered flavors and aromas from those the hop presents before being added to fermentation. If the goal of dry-hopping is experimentation, then trying many different hop varieties during active fermentation is a good place to start. If a more reliable outcome is the object for your homebrew, try dry-hopping after fermentation. The standard American IPA was built on dry-hopping after fermentation.
For homebrewers, this means waiting for activity in the airlock to cease for 12 to 24 hours before adding a dose of hops. Amounts for a standard 5-gallon batch vary from about half an ounce for something subtle like a blonde ale to more than 5 ounces for hoppy IPAs. One major advantage to adding the hops promptly to the vessel the beer fermented in is the CO2 produced by fermentation is still filling the headspace over the beer, so there is less oxygen introduced when adding the hops.
Exposure to oxygen starts a chain of oxidation reactions that create undesirable results, like sweet cherry or cardboard flavors, and dulling of hop aroma. You comment about dry hopping in the keg producing grassy or vegetal flavors is simply not true at typical kegging temperatures. In fact, it may be a month before the aroma peaks. Also, for the majority of us who have been at this for a while 35 years for me , only use primary fermentation, not secondary, except in the case of aged beers.
One can simply dry hop in primary glass carboy for me once active fermentation has slowed. Thanks for the information about Primary. I have a IPA in glass Carboy 2 weeks and have dryhopped centennial pellets. Hope it comes Out ok. This is true Rich…. Great info and overview, especially the split batch approach. About to start another brew and dry hop some Mosaic hops so the primary vs secondary hopping will definitely be in order for comparison.
Tks and Merry Christmas. I have dry hopped in the keg and over time I get tea like, and grassy off flavors. So I agree with this author on what he says about dry hopping too long from my personal experience. This time I am dry hopping in the secondary for days before kegging.

Comments Great info to have. Thanks for putting this together. Great tips for dry hopping. This was one of the main questions I had when I started brewing. Thanks for the info. Add it at the end of the secondary fermentation instead of the beginning. Thank you the article. You have taken my beer knowledge to a new level. I've always done loose dry hops as well. I actually much prefer it and anytime I've dry hopped in the fermenter that's how I've done it.
This latest batch with zero hops in the fermenter was way different than what I usually do. The above set up dry hopping under pressure with temp control to floc the yeast is absolutely ideal.
I'll prob look into rigging up something like that soon. I understand that hopping in a bag definitely decreases utilization, but I felt a little better about it due to the fact that I'd be shaking and rolling it pretty vigorously. When I took the bag out, after 24 hours, all the hops "appeared" to be completely broken down and fully saturated with liquid.
I'm sure extraction would have been better if they were loose, but it's hard to really say by how much. I should also add that I used a large 5 gallon paint strainer bag. Tons of room for the hops to move around. I cant stand to have hop particles in my beer.
It never fails you hear about people keg line getting plugged. I dont cold crash so I always use a paint strainer bag. I usually dry hop on day 2 of fermentation for about 3 days. Many ways to skin a cat they say. You must log in or register to reply here. Similar threads. How long should I Dry Hop? Replies 10 Views 5K. Dec 27, Justdrumin. How long should Dry Hop last and why?

I added a dry hop charge to one beer 3 days into fermentation then waited another 4 days before adding an identical amount of hops to the second beer.
After an additional 3 days, I took hydrometer measurements showing both batches had reached the same FG. Left: 3 day dry hop 1. At this point, each beer was pressure transferred to a CO2 purged keg and placed next to each other in my keezer where they were burst carbonated overnight before I reduced the gas to serving pressure.
The beers were ready to serve after a couple days of conditioning. Left: 3 day dry hop Right: 7 day dry hop. Utilizing 4 opaque cups of the same color where 2 were inconspicuously marked, one set was filled with the beer dry hopped for 3 days while the other set was filled with the beer dry hopped over 7 days.
For each triangle test, 3 of the 4 cups were indiscriminately selected, thus randomizing which beer was the unique sample for each trial. Following each attempt, I noted whether I was correct in identifying the unique sample. There are a number factors a brewer must consider when planning to dry hop a beer— amount of hops, number of additions, temperature, and of course, how long to let the hops stay in the beer.
Despite evidence suggesting oil extraction occurs in as little as 24 hours, some prefer to dry hop for as long as 2 weeks, which others claim can lead to grassy off-flavors. When comparing beers dry hopped for either 3 or 7 days, I was unable to reliably distinguish them and felt they were identical in every perceptible way.
