Dry hopping is one of the simplest and most effective upgrades you can make to a home brew. It adds intense hop aroma — the kind you get in a good craft IPA or pale ale — without increasing bitterness. You don't need any specialist equipment, it works with beer kits as well as all-grain recipes, and the difference it makes to the finished beer is immediately noticeable.
This guide covers everything you need to know: what dry hopping actually does, when to add the hops, how much to use, which varieties work best, and how to do it cleanly without introducing oxygen or infection.
What Is Dry Hopping?
Dry hopping means adding hops directly to the fermenter — without heat — during or after fermentation. Unlike hops added during the boil, which contribute bitterness as their volatile aroma compounds are driven off by heat, dry hops steep in the beer at fermentation temperature and release their oils directly into the liquid. The result is a pronounced hop aroma with little or no additional bitterness.
The technique has been used in British brewing for centuries — traditional dry-hopped cask ales are a good example — but it's become particularly associated with modern American IPAs and hazy NEIPAs, where the hop aroma is often the defining characteristic of the beer.
What Equipment Do You Need?
For most home brewers, you need very little beyond what you already have. If you're fermenting in a bucket, you can add pellet hops directly through the lid. If you're using a demijohn or carboy, pellets will pass through the neck easily.
If you want a cleaner, more controlled dry hop — particularly useful for whole leaf hops or if you want to remove the hops easily before packaging — our Stainless Steel Dry Hopper is worth considering. It holds the hops in a perforated stainless basket that sits inside the fermenter, allowing full contact with the beer while keeping the hop material contained and easy to remove. It's a significant step up from adding loose pellets, particularly if you dry hop regularly or in larger volumes.
A Muslin Straining Bag is a simpler alternative for whole leaf hops — place the hops in the bag, tie it off, and lower it into the fermenter. Less precise than a stainless hopper but perfectly effective for occasional use.
When Should You Add Dry Hops?
Timing matters more than most beginners realise. There are two main approaches:
After primary fermentation (most common)
Wait until primary fermentation is complete — confirmed by a stable hydrometer reading over 2–3 days — then add your hops. Leave them for 3–5 days at fermentation temperature before packaging. This is the standard approach and produces excellent results. The beer is stable, there's no risk of CO₂ produced during fermentation blowing off your hop aroma, and the process is straightforward.
During active fermentation (biotransformation)
Adding hops while fermentation is still active — typically around day 2 or 3 when activity is slowing but not finished — is a technique used to encourage biotransformation. The yeast interacts with the hop compounds and can produce more complex, tropical fruit characters. It's more commonly used in NEIPA brewing and requires a bit more experience to judge the timing correctly. For most home brewers, post-fermentation dry hopping is the better starting point.
How Much Should You Use?
For a standard 23-litre batch, a good starting point is:
- Light dry hop (subtle aroma boost) — 20–30g
- Medium dry hop (noticeable hop character) — 40–60g
- Heavy dry hop (IPA/NEIPA level aroma) — 80–120g+
For a one-gallon (4.5 litre) batch, scale down proportionally — 5–10g is usually enough for a noticeable effect.
If you're dry hopping a beer kit for the first time, 25–30g of a single variety is a good place to start. It's enough to make a clear difference without overwhelming the base beer.
Which Hops Should I Use for Dry Hopping?
Not all hops are equally suited to dry hopping. You want varieties with high oil content and pronounced aroma. Here are the varieties we'd recommend most often:
For citrus and tropical fruit character
- Citra — intensely citrusy with lime and tropical fruit. The most popular dry hop variety in modern craft brewing. Use with some restraint — it's powerful.
- Mosaic — blueberry, tropical fruit, and a hint of earth. Complex and layered. Works brilliantly on its own or blended with Citra.
- Galaxy — passion fruit, peach, and citrus. An Australian variety that's become a favourite for hazy IPAs.
- Amarillo — orange, grapefruit, and apricot. Softer than Citra, excellent blended with it.
- Nectaron® — pineapple, peach, and passion fruit. A New Zealand variety producing intensely tropical results.
For a more traditional British character
- East Kent Goldings — floral, spicy, and smooth. The classic dry hop for traditional British ales and bitters.
- Fuggles — earthy and herbal. Excellent in porters, milds, and traditional English ales.
For something in between
- Cascade — grapefruit and floral. Less intense than Citra, more approachable. A great first dry hop variety.
- Olicana — tropical fruit with a British backbone. A modern UK variety that bridges both worlds.
If you're not sure which variety to choose, the Mangrove Jack's flavour descriptor range labels hops by character (Citrus, Tropical, Floral, etc.) rather than variety name — a useful option if you're new to hops.
Step-by-Step: How to Dry Hop a Beer Kit
Step 1 — Brew your kit as normal
Follow the kit instructions through primary fermentation. Don't add the dry hops until fermentation is complete.
Step 2 — Confirm fermentation is finished
Take a hydrometer reading and confirm it's stable over 2–3 days. Adding dry hops to an actively fermenting beer isn't harmful, but the CO₂ being produced will carry some of your hop aroma out of the beer before it can be absorbed. Waiting until fermentation is complete gives better results.
Step 3 — Prepare your equipment
Sanitise anything that will touch the hops or the beer. If you're using a Stainless Steel Dry Hopper, load it with your hops and sanitise the outside before lowering it into the fermenter. If you're using a muslin bag, place the hops inside and tie it off. For loose pellets in a bucket, you just need a sanitised surface to work on.
Step 4 — Add the hops
Open the fermenter, add the hops by your chosen method, and reseal promptly. Minimise the time the fermenter is open to reduce oxygen pickup. Replace the airlock.
Step 5 — Leave for 3–5 days
Keep the fermenter at fermentation temperature (18–22°C for most ales). You may see some renewed airlock activity as the hops release CO₂ — this is normal. After 3–5 days, the aroma extraction is largely complete. Leaving hops for longer than 7 days can start to introduce grassy or vegetal notes, particularly with pellets.
Step 6 — Package as normal
If using a dry hopper or muslin bag, remove it before packaging. Rack, bottle, or keg as you normally would, taking care to leave any hop sediment behind.
Common Dry Hopping Mistakes
- Adding hops too early. If fermentation is still very active, CO₂ will scrub out much of the aroma before it can be absorbed. Wait until the gravity is stable or nearly stable.
- Leaving hops in too long. Beyond 7 days, pellet hops in particular can start to contribute grassy, vegetal notes. 3–5 days is the sweet spot for most varieties.
- Introducing oxygen. Every time you open the fermenter, you risk oxidation. Be quick, minimise exposure, and reseal promptly. A dry hopper with a sealed entry point reduces this risk considerably.
- Using too little. A 10g dry hop in a 23-litre batch will have a barely perceptible effect. If you want to notice the difference, use at least 20–30g.
Frequently Asked Questions
Can I dry hop a lager?
Yes, though it's less common. Lagers are typically fermented cold (8–12°C), which slows hop oil extraction. If you want to dry hop a lager, either do it at the end of fermentation before cold conditioning, or raise the temperature slightly for the dry hop period. Use appropriate varieties — Saaz or Hallertauer Mittelfrüh for a traditional character, or modern varieties like Galaxy for something more contemporary.
Do I need to sanitise the hops?
No. Hops have natural antimicrobial properties and the alcohol content of the beer provides protection. Adding unsanitised hops directly to finished beer is standard practice and carries very low infection risk. Focus your sanitising efforts on any equipment that touches the hops or the beer — including your dry hopper or muslin bag.
Can I dry hop more than once?
Yes — double dry hopping (DDH) is a common technique in NEIPA brewing. A first dry hop addition is made during or just after fermentation, then a second addition is made a few days later before packaging. This builds a more complex, layered hop aroma. It does increase the risk of oxygen pickup, so work quickly and carefully — a stainless dry hopper makes repeated additions much easier to manage.
Will dry hopping make my beer hazy?
Pellet hops can cause some temporary haze, particularly if the beer is disturbed after dry hopping. This usually settles with time and cold conditioning. If you're deliberately making a hazy NEIPA, the haze from dry hopping is part of the style. If you want a clear beer, rack carefully and allow extra time for conditioning before serving.
Can I dry hop with whole leaf hops instead of pellets?
Yes. Whole leaf hops are easier to remove after dry hopping — particularly if used in a muslin bag or stainless dry hopper — and some brewers prefer them for this reason. They absorb slightly more beer than pellets, so account for a small volume loss. Pellets are generally more efficient and easier to work with for most home brewers.
