Other extracts are available as well, in the form of gelatinous hops liquids containing both resins and acids, and even pure isomerized alpha-acid extract. Whichever form you choose, composition matters as well. Terroir is a concept more common to winemaking than brewing, but there is absolutely no question that climate, soil composition, and growing condition variations that are part of the hops-growing process have a substantial impact on their flavor.
American Hallertau is simply a different hop from German Hallertau, and we should consider hops geography when we plan out our recipes.
Hops are a key component of beer—maybe the key component of beer—and we owe it to the beer to use our hops purposefully, thoughtfully, and deliberately. A good grounding in what hops add to our beer based on when we add them to the beer is a valuable and useful thing. It makes it possible to make meaningful changes to recipes and processes when we seek to incorporate our impressions and feedback. All of this should carry an important disclaimer, however: try, then trust. We know too little about hops, and though that base of knowledge is increasing quickly, a wide range of recipe- and system-specific factors can make your mileage vary.
Water chemistry, burner and kettle geometry, ingredient interactions, and more can all blunt or amplify different elements of hops flavor and contributions. My advice for your first experiments with dry hopping would be to pick a traditional aroma hop and use no more than 1 ounce 28 g.
This will give you a good idea of what dry hopping does for a beer. From there you are only limited by your own sense of adventure in deciding what hops to try and how much to use. The final question in dry hopping is whether or not to put your hops in a bag. On the other hand, hops tend to expand when wet, so a bag that you were able to stuff through the neck of a carboy dry may be difficult or impossible to get out when fully saturated. Another issue with bagging is that it tends to reduce the hops exposure to the beer.
Also, while the hops are naturally resistant to bacteria, the bag is not. Because of this, you should always boil the bag to sanitize it before putting hops in it.
Dry hopping is being practiced excessively these days. Quite a few IPAs are double and triple hopped. But for a long time only pale ales and IPAs were treated on cold side. Substituting hop pellets with CO2 hop extract increases yields and can produce cleaner, brighter beer while maintaining hop varietal character.

Pros and cons Due to the fact that no volatile oils are boiled off, the benefit to dry hopping is that the brewer can get as much flavor and aroma possible into the final beer. Which hops to use? Pellets, plugs or loose? How much? To bag or not to bag? Written by Donald Million Issue: September This website uses cookies to improve your experience.
You can opt-out if you wish. You want the beer to mingle with the hops. Or a handy tip is to wedge the bag between the keg wall and the dip tube, as near to the bottom as possible. Because the lupulin glands are burst, all the oil goes into the beer at once. Just be patient and it will mellow out. This acts like a time release effect and keeps the aroma level reasonably constant over time. Like almost everything in brewing, how much hops to use when dry hopping depends on a lot of factors.
How hoppy do you want the beer to be? What kind of hops are you using? What is their oil content? Where are you dry hopping? How much time do you have? What is the temperature? Some hops have a more potent or distinctive aroma than others. For example Cascade usually has reasonably high oil levels and has a very distinctive, citrusy aroma that comes through even when the oils are lower. Oil levels in the hops start out high near harvest time and get lower as the hops age. East Kent Goldings, on the other hand, typically has lower oils to start with and a mellow aroma that has a hard time competing with the other beer flavors.
To put this in perspective, it would be common to use 1. As for what varieties you can use, there are no rules, so feel free to experiment you might just invent a new style! The most popular hop for dry hopping in the United States is Cascade. But you can use any hop with decent aroma. The newer high-alpha hops are being used a lot these days, with Centennial and Columbus heading the list.
If you can imagine that aroma in your beer, go for it! You might also experiment with mixing varieties. Temperature also plays a role in the quality and strength of the hop aroma. Warmer temperatures extract more oils than colder temperatures — this is particularly evident with whole hops.
If you are a hophead, always use more hops than less if there is a question. Bittering The primary use of hops is for bittering. Bittering hops additions are boiled for minutes to isomerize the alpha acids; the most common interval being one hour.
The aromatic oils of the hops used in the bittering addition s tend to boil away, leaving little hop flavor and no aroma.
Because of this, high alpha varieties which commonly have poor aroma characteristics can be used to provide the bulk of the bitterness without hurting the taste of the beer. If you consider the cost of bittering a beer in terms of the amount of alpha acid per unit weight of hop used, it is more economical to use a half ounce of a high alpha hop rather than 1 or 2 ounces of a low alpha hop. You can save your more expensive or scarce aroma hops for flavoring and finishing.
Flavoring By adding the hops midway through the boil, a compromise between isomerization of the alpha acids and evaporation of the aromatics is achieved yielding characteristic flavors.
These flavoring hop additions are added minutes before the end of the boil, with the most common time being 30 minutes. Any hop variety may be used. Usually the lower alpha varieties are chosen, although some high alpha varieties such as Columbus and Challenger have pleasant flavors and are commonly used.
Finishing When hops are added during the final minutes of the boil, less of the aromatic oils are lost to evaporation and more hop aroma is retained. A total of oz. Finishing hop additions are typically 15 minutes or less before the end of the boil, or are added "at knockout" when the heat is turned off and allowed to steep ten minutes before the wort is cooled.
In some setups, a "hopback" is used - the hot wort is run through a small chamber full of fresh hops before the wort enters a heat exchanger or chiller.
