Introduction to Dry Hopping
If you’ve been drinking craft beer in the past few years, you’ve doubtless seen the term “dry-hopped” on labels or menus. In the never-ending quest for hop flavor, brewers have gone to great extremes to give their IPAs an added punch. One of the most popular (and discussed) processes in modern brewing is dry hopping.
But what is this magical technique that makes an IPA taste like grapefruit juice? We’ll discuss how it’s done and why, and include a few tips for employing dry hopping in your homebrewing operation.

What Is Dry Hopping?
Most traditional hopping is done during the boil. “Dry hopping” refers to the process of adding hops after the boil, typically during fermentation or even after. The goal is to add even more intense hop aromas without bitterness, as the hops added during fermentation won’t be boiled in the wort.
To get technical, this means the hop’s alpha acids won’t be isomerized and won’t add bitterness.
“Wet hopping” refers to the addition of hops that have recently been harvested and haven’t been dried out. This is a distinct process and doesn’t pertain to the standard hop additions that happen during the boil or even dry hopping.
When Is Dry Hopping Done?
Dry hopping can be done at different stages of brewing, each with its own impact on flavor and aroma:
- Pre-fermentation: Although rare, you can start your dry-hopping schedule as you add the yeast before fermentation starts to happen.
- Late fermentation: The most common method. Adding hops late in the fermentation process limits oxygen and takes advantage of biotransformation. Brewers typically start around day 2–4 of active fermentation, when the yeast interacts with hop compounds to create desirable flavors and aromas.
- Post-fermentation: Also known as cold-side dry-hopping, adding hops after fermentation is complete preserves raw hop aroma and reduces “hop creep.” This is more common for brewing West Coast IPAs.
- Secondary conditioning: Once the beer is in the keg, dry hopping provides an additional infusion of aroma and flavor. This is common for brewing New England IPA.
- Gradually: One of the most common techniques is adding hops during various stages, including the boil, early fermentation, late fermentation, and during conditioning. This allows layered complexity and vibrancy in the hop profile.
What Does Dry Hopping Do to Beer?
Dry hopping primarily enhances aroma by extracting volatile hop oils (myrcene, humulene, linalool, etc.) that would otherwise be boiled off. This allows the desirable floral, citrus, and pine aromas to shine. It also adds complexity without bitterness, since the hops’ alpha acids are not isomerized.
Appearance can also change. Dry hopping often creates a hazy look—especially in NEIPAs—which is highly desirable these days.
What Is Double Dry Hopping (DDH)?
The “DDH” label is one you’ll see on many hyped-up New England IPAs. Double dry hopping isn’t a technical term with a set definition. It’s essentially a marketing term that conveys that boatloads of hops are added after the boil, promising intense hop aromas without extra bitterness. From a brewer’s standpoint, DDH can literally mean doubling the hop bill in the recipe.
Double dry hopping can be done in a few different ways:
- Dry hopping the beer at two separate stages, such as during active fermentation and then again a few days before packaging.
- By adding twice the amount of hops.
- Or both!
Timing Strategies in Double Dry Hopping
The first addition usually happens during active fermentation (around days 3–5). This takes advantage of biotransformation, helping to minimize oxygen exposure. The second addition occurs post-fermentation, either in the fermenter or during packaging. This stage helps extract hop oils and aromas without bitterness.
Why Brewers Use Double Dry Hopping
Brewers use DDH for several reasons: it creates more intense hop aroma, adds layered complexity, and showcases hop varieties like Citra or Galaxy more expressively. It also fits perfectly with the hazy IPA trend—the “DDH” label itself has become a strong marketing tool.
Best of all, double dry hopping boosts hop flavor and aroma without increasing bitterness, making beers more palatable for drinkers who prefer sweeter, juicy profiles.
Key Differences Between Dry Hopping and Double Dry Hopping
| Aspect | Dry Hopping | Double Dry Hopping |
|---|---|---|
| Definition | Adding hops after the boil (usually during or after fermentation) to boost aroma and flavor without adding bitterness. | Doubling the hop load, or adding hops during both fermentation and conditioning. |
| Primary Purpose | Enhance hop aroma and preserve volatile oils. | Introduce a secondary hop addition for “double” the effect. |
| Timing | Post-boil, during, or after fermentation. | During fermentation and again in conditioning. |
| Hop Contact with Heat | No heat—preserves delicate aromatics. | Mild fermentation warmth, never boiling. |
| Impact on Bitterness | Minimal; mostly aroma and late flavor. | Greater flavor/aroma enhancement with minimal bitterness. |
| Flavor Profile | Fresh, bright, intense hop aroma (citrus, pine, floral, tropical, herbal). | More integrated, with a stronger hop profile. |
| Common Styles | American IPA, NEIPA, Pale Ale, hop-forward beers. | New England IPAs. |
Pros and Cons of Dry Hopping Techniques
| Technique | ✅ Pros | ❌ Cons |
|---|---|---|
| Dry Hopping | – Boosts hop aroma without bitterness – Easy to control – Lower cost than double dry hopping | – Aroma can fade quickly – Risk of grassy flavors if hops sit too long |
| Double Dry Hopping | – Intense, layered hop aroma – Trendy in modern IPAs – Greater complexity in flavor and aroma | – Higher hop cost – Can cause hop burn (harsh, vegetal taste) – May lead to haze instability |
Tips for Successful Dry Hopping at Home
Homebrewers can achieve great results with dry hopping if they follow a few best practices. Use the right tools, such as hop bags or mesh filters, to prevent clogging. Limit dry hop contact to 2–5 days to avoid grassy flavors, and carefully time additions during fermentation. Stirring the beer can help extract hop oils more efficiently.
Minimizing oxygen exposure is crucial, so purge with CO₂ if possible. Finally, control the temperature consistently during dry hopping, and chill the beer after hopping to help settle particles.

Conclusion
Whether you’re a hop-head looking for the juiciest New England IPA or a homebrewer trying out a new recipe, dry hopping is a massive part of the craft beer lexicon. The world of IPAs offers plenty of different drinking experiences, but sometimes you just need that citrus kick a dry-hopped beer provides.
Even better, brewers have been experimenting with dry-hopping crispy pilsners, saisons, and other styles as well!
