How to Dry Hop a Home Brew Beer Kit — Step by Step

Dry hopping is the single biggest upgrade you can make to a home brew beer kit. It takes an extra 5 minutes, costs around £1.50–£3.00 per batch, and produces a noticeably more aromatic, craft-quality result. Yet most kit brewers never try it. This guide explains exactly how it works and how to do it properly.

What Is Dry Hopping?

Dry hopping means adding hops directly to the fermenter after primary fermentation — without boiling them. The hops steep in the beer at fermentation temperature, releasing their aromatic oils without contributing bitterness. It's how most commercial craft breweries get that vivid tropical, citrus, or floral hop aroma into their beers.

The reason kit beers often lack hop aroma isn't because the recipe is bad — it's because all the aromatic compounds in the kit's hops were driven off during the extraction and canning process. Dry hopping puts them back.

What You Need

  • Your beer kit, brewed and in primary fermentation
  • Hop pellets — Citra, Centennial, or Willamette are ideal starting points
  • A hydrometer to confirm fermentation is complete
  • A sanitised spoon or measuring scoop

How Much Hops to Use

For a 23-litre batch:

  • Light dry hop (subtle aroma): 20–25g
  • Standard dry hop (noticeable craft character): 30–50g
  • Heavy dry hop (NEIPA-style intensity): 60–100g

Start at 30g for your first attempt. You can go heavier in future batches once you understand the hop character.

The Best Hops for Dry Hopping a Kit

  • Citra — tropical fruit, passion fruit, lime. Intense and modern. Best for IPAs, pale ales.
  • Centennial — grapefruit, lemon, floral. Classic American IPA character. More balanced than Citra.
  • Willamette — earthy, floral, slightly spicy. Great for British bitters and golden ales.
  • Bullion — blackcurrant, dark fruit. Excellent dry hop for stouts and porters.

Step-by-Step: How to Dry Hop a Beer Kit

  1. Wait for primary fermentation to slow. This is usually day 4–6, when bubbling in the airlock has slowed significantly. Confirm with a hydrometer if possible — gravity should be close to its expected final value.
  2. Measure your hops. Weigh out 30–50g of pellet hops using a digital scale.
  3. Add directly to the fermenter. Open the lid, pour the hop pellets in, replace the lid. That's it. You don't need to sanitise the hops — their low pH and natural antimicrobial properties mean they're safe to add directly. The pellets will initially float then slowly sink.
  4. Leave for 3–4 days. Keep the fermenter at fermentation temperature (18–22°C). Don't be alarmed if the airlock starts bubbling again — the hops can disturb some residual CO2 in solution.
  5. Cold crash if possible. Cooling to 2–4°C for 48 hours before bottling drops the hop material to the bottom and produces a clearer beer. If you can't cold crash, bottle carefully to avoid disturbing sediment.
  6. Bottle as normal with Carbonation Drops and condition 2 weeks before drinking.

Tips for the Best Results

Use a hop bag for easier transfer. If you find hop material getting into your bottles, put the pellets in a Muslin Bag or Nylon Straining Bag before adding to the fermenter. Tie it off and you can remove it cleanly before bottling.

Don't dry hop for longer than 5 days. Beyond 5 days, hop material can contribute grassy, vegetal off-flavours. 3–4 days is the sweet spot for most pellet hop additions.

Match the hop to the kit style. Citra on a Coopers Stout won't work — the tropical character clashes badly with roasted malt. Use Citra and Centennial for pale ales and IPAs; Willamette and Bullion for darker styles.
