  • 1 30 litre fermenter
  • 1 Large mixing spoon
  • 1 5 litre jug
  • 1 Cup


  • 1.8 kg Muntons Continental Lager
  • 1.5 kg Muntons Vienna Lager
  • 1 pkt 34/70 Lager yeast


  • Clean and sanitise fermenter, spoon, cup and jug.
  • Fill the cup to 3/4 full with cold brewing water. Sprinkle in the dried yeast and gently stir in. Cover.
  • Soften the malt cans in hot water for about 5 minutes.
  • Pour 2 litres of boiling water into your 5L jug. Open the cans and pour the contents into the jug.
  • Mix the concentrated wort and water well, then pour into your fermenter. Top up with cold quality brewing water to 23L for approx. 4.8% ABV. Vigourously stir the wort with a large spoon to oxygenate it. Ensure the wort temperature is 9 - 22 degrees celcius. Gently pour in the cup of yeast slurry and gently stir into the oxygenated wort.
  • Seal the fermenter lid and insert airlock. Ideally ferment at 14-18 degrees Celcius for 10 - 14 days.
  • After 10 days, check the gravity. If the SG remains steady for three days, fermentation is complete. If in doubt, leave a few more days for better results. Keg or bottle your brew.
