Ingredient List


Fermentables

  • 2kg Dextrose (Glucose) – Produces a cleaner finish than table sugar and avoids cidery flavours.
  • 500g Dry Malt Extract – Adds body, depth, and a beer-like backbone.
  • 500g Lactose – Non-fermentable sugar that adds sweetness and mouthfeel safely.

Flavour Builders

  • 100–200g Fresh Ginger (finely grated) – 100g for mild warmth, 200g for a strong spicy kick.
    Tip: Wash well but don’t peel — ginger skin contains aromatic oils.
  • Up to 4 Lemons (optional) – Adds brightness and freshness; peel increases aroma but can add bitterness.

Yeast and Brewing Aids

  • 5g Yeast Nutrient – Supports healthy fermentation in sugar-heavy recipes.
  • 1 sachet SafAle Yeast – Clean-fermenting yeast that lets ginger shine.


The Equipment You’ll Need


  • 25–30L Fermenter
  • Bottles (glass or plastic rated for carbonation)
  • Airlock and fermentation lock
  • Priming scoop or measuring spoon
  • Homebrew sanitiser

Short on Time? Try a Ginger Beer Kit


If you want consistent results with minimal effort, pre-balanced ginger beer kits are a great alternative.



Troubleshooting Guide


Airlock Not Bubbling

Fermentation may still be active. Check gravity readings instead of relying on bubbles.


Medicinal Flavour

Usually caused by chlorine in tap water. Use filtered or bottled water.


Too Dry

Increase lactose next batch or sweeten in the glass, never in the bottle.


Cloudy Ginger Beer

Normal for ginger beer. Extra settling time or cold crashing improves clarity.
