Coopers Carbonation Drops provide a quick, tidy way to prime bottled beer without measuring loose sugar into every bottle. The 250g pack contains pre-measured drops for consistent dosing.
Dosage
- Use 1 drop per 345–375ml bottle.
- Use 2 drops per 740–750ml bottle.
How to use
- Make sure fermentation is fully complete before bottling.
- Add the correct number of drops to each clean, sanitised bottle.
- Fill and seal the bottle, leaving the headspace recommended by your recipe.
- Condition at the appropriate temperature until carbonated.
Alternative options
You can also use Brew Master Carbonation Drops or Mangrove Jack’s Carbonation Drops. Check the individual pack for its dosage.
Helpful addition
750ml PET beer bottles are a practical reusable option for bottle-conditioning home brew.

The three 1kg products are added at the fermenter and give different balances of alcohol, body and malt character. Carbonation drops are used later for bottle priming after fermentation is complete.
