House Hard Ginger Beer

(Airlock + Cold Crash Method — Alcoholic Ginger Beer)

Recipe Details

  • Yield: 1 gallon
  • Target ABV: ~4–4.5%
  • Carbonation: Medium, beer-like
  • Profile: Smooth ginger heat, lightly sweet to semi-dry, bright citrus finish

Ingredients

  • 12 oz (340 g) fresh ginger (Scrubbed, skin on, sliced into ⅛–¼” medallions, lightly crushed)
  • 2½ cups (500 g) white sugar (Fermentable base)
  • ¼ cup (2–3 lemons) lemon juice (Adds acidity & brightness)
  • To 1 gallon water (Filtered preferred)
  • ½ tsp champagne yeast (Clean, high attenuation yeast)

Equipment

  • 1-gallon glass fermenter
  • Stopper + airlock
  • Large pot
  • Strainer (optional)
  • Siphon/racking cane
  • Swing-top bottles (~16 oz)
  • Measuring spoon (½ tsp)

Method

1. Ginger Extraction

  1. Add to pot:
    • 6–7 oz sliced ginger
    • 2½ cups sugar
    • ~2 quarts water
  2. Bring to gentle simmer (not a rolling boil).
  3. Simmer 20 minutes.
  4. Remove from heat. Add remaining ginger (and optional lemon zest).
  5. Cool to warm.

2. Fermenter Setup

  1. Strain into fermenter (or leave slices for stronger ginger).
  2. Add lemon juice.
  3. Top up with cool water to 1 gallon total.
  4. Ensure liquid is below 90°F (32°C).
  5. Pitch ½ tsp champagne yeast.
  6. Seal with airlock.

3. Primary Fermentation

Duration: 4 days at room temperature (65–75°F ideal)

Signs of healthy fermentation: * Airlock bubbling within 12–24 hours * Ginger pieces rising and falling * Thin foam ring forming

By Day 4: * ~4–4.5% ABV * Light sweetness remaining * Ginger flavor smooth and integrated

4. Cold Crash

  1. Move fermenter to fridge.
  2. Keep airlock installed.
  3. Cold crash 48 hours.

Purpose: Yeast and sediment drop out; clarifies liquid; stabilizes sweetness & alcohol level.

5. Rack & Bottle

  1. Siphon clear liquid off sediment.
  2. Bottle into clean swing-tops.

Priming Sugar (for carbonation): Add to each 16 oz bottle: - [ ] ½ teaspoon white sugar

Produces medium, beer-like carbonation with low pressure risk.

6. Bottle Conditioning

  • Store bottles at room temperature.
  • Carbonation develops in 3–7 days.

First Check: Chill one bottle on Day 4 or 5, then open: * Light fizz → wait longer * Steady bubbles → ready * Strong rush → refrigerate all bottles

Once ready, refrigerate all bottles.

Final Profile

  • Alcohol: ~4–4.5% ABV
  • Sweetness: Lightly sweet / semi-dry
  • Ginger Heat: Smooth, warming, not harsh
  • Carbonation: Crisp, controlled, beer-like

Future Adjustments

  • More ginger bite: Increase ginger to 14–16 oz.
  • Drier finish: Extend primary to 5–6 days.
  • More carbonation: Use ¾ tsp priming sugar per bottle.
  • Lower alcohol: Reduce sugar to 2 cups.
