What Is Dry Hopping?

Dry hopping beer is a brewing process that adds hops, specifically the essential oils and resins found in them, to beer after fermentation.

This process can give the beer an intense hoppy aroma and flavor. It’s a popular technique among craft brewers looking for unique flavor profiles for their beers, but what exactly is dry hopping?

Dry hopping is a process by brewers to add character and hop aroma to finished beer without adding bitterness.

The term dry hopping originated centuries ago with British brewers and was used to add hops to the cask shortly before it made its way to the customer. British hop producers specifically developed 1/2-ounce hop plugs to add whole hops to a keg or cask conveniently.

Nowadays, dry hopping refers to any hop addition after the wort has been cooled. These additions can be made in the primary fermenter, in the secondary, or by adding hops directly to a keg.

The process involves adding hops—usually whole hops or pellet hops—directly into the finished beer as it ferments or ages in conditioning tanks or casks.

The hops are left in contact with the liquid for several days or weeks while they impart their flavor and aroma compounds into the beer.

This hopping method differs from traditional bittering methods, which involve boiling hops to extract bitterness from them.

How To Dry Hop Beer

Dry hopping beer is relatively simple once you’ve mastered basic homebrewing techniques like fermentation and bottling/kegging.

First, you’ll want to ensure that your wort has already been through primary fermentation before adding your chosen hops into the fermenter or aging vessel.

You’ll also want to ensure that your fermentation temperature does not exceed 70°F (21°C).

Once those steps have been completed, add your desired amount of hops directly into the fermenter/aging vessel and allow them to steep for 3-7 days before transferring them into kegs/bottles for carbonation and serving.

For American Pale Ale and IPA beer styles to have vibrant hop flavor and aroma, dry hopping is necessary.

Dry hopping homebrew may lend an excellent layer of fresh hop aromatics to beers like Pilsner and Saison.

Dry hops are a quick and easy process that significantly enhances the flavor.

Benefits of Dry Hopping

The main benefit of dry hopping is that it gives beers more intense hop aromas and flavors without introducing additional bitterness.

By avoiding boiling, you get all the fruity and floral notes associated with each type of hop without harsh, unpleasant flavors from the alpha acids.

Additionally, dry hopping helps improve head retention on certain beers by adding proteins that can help stabilize foam on top of the glass.

In some cases, dry hopping may also prevent oxidation due to its antiseptic properties.

The dry hopping process is easier than other forms of brewing because you don’t have to boil wort; you add your chosen hops to the fermenter or aging vessel and let them sit until the desired hop character is achieved.

When And Where To Dry Hop?

You can dry hop in a few spots during the fermenting process:

Primary Fermenter: Dry hopping is the most efficient and feasible method for all beer genres. There is very little danger of oxygen exposure during dry hopping at various points during the fermentation.

Secondary Fermenter: We do not advise using secondary fermentation for dry-hopping. Racking beer between fermenters will likely give it unwelcome oxygen.

Keg: It’s great to dry hop the keg to add intense and vibrant hop flavor. Before transferring the beer into the keg, add hops to a hop bag or stainless steel canister.

When transferring dry hopped beer to your keg or bottling bucket, it’s imperative to limit any exposure to oxygen to the best of your ability.

Consider placing a floating dip tube in your keg to draw beer from the top to prevent a clogged poppet.

A note on dry hop temperature: The fermenter’s temperature affects the effectiveness of the extraction process.

Extracting hop oils and aromatics more quickly in warmer temperatures is easier. It can take longer if it’s colder.

As a general rule, we advise dry hopping at the temperature of your primary fermentation and giving the hops at least 3 to 4 days to impart their flavor.

But anything between 48 and 72 hours is the best time for dry hopping. If you wait any longer, you risk causing hop creep and losing the ability to extract vital essential oils and aroma hops.

Types for Dry-Hopping

The type of hop used and the desired character will determine which hops work best for dry hopping.

American hops like Cascade, Centennial, Citra, Simcoe, and Amarillo are popular choices.

New Zealand or Australian varieties are also popular since they impart a more tropical and fruity character.

European hops such as Saaz, Hallertau, and Tettnang can also be used for dry hopping, but they tend to have a more subtle flavor.

To get the best of both worlds (fruity and floral characters), you can use blends of different hop varieties in your dry hopping.

Hop Form

You can select the type or form of the hop you’ll use in your dry-hopping operation in addition to variety.

Typically, you can get hops as entire cones, pellets, or frozen hops.

Depending on the strategy you choose, each offers a unique set of advantages. However, there are various times when you should add it to your brew.

Whole Cone Hops

These hops should be used within 3 months of being harvested for maximum potency.

Whole cone hops usually require more volume to achieve the same flavor as pellet or frozen hops.

Whole cone hops also tend to be more expensive than pellets or frozen hops, but they provide fresher hop aromas and flavors since they aren’t as processed.

Pellet Hops

Pellets are a great option. They are made from whole cone hops that have been compressed, so they don’t require as much volume to achieve the same flavor profile.

Whether you dry hop with whole leaf or pellet hops is up to you: Leaf hops tend to float on top of the liquid, while pellet hops will disintegrate into a hops sludge that sinks to the bottom.

Conclusion

Dry hopping is one way that craft brewers can make unique beers with complex flavor profiles while maintaining balance within their recipes.

While it may seem intimidating at first, once you get the hang of it, you’ll find that it’s relatively simple and opens up a whole new world of possibilities for creating delicious beers!

With careful consideration given to recipe formulation and some trial and error, anyone can master this technique and enjoy great results every time!
