15 Feb 2018

  1. Crush grain
  2. Steep 20min in 72-75 °C Water
  3. Sparge with light DME
  4. transfer 1 gal in brewing pot
  5. Brewing
  • 00:00 - Bring wort to a boil (100 °C)
  • 12:00 - Wort boiling
  • 12:05 [60min] - Add hops (14.14 g German Hallertau)

  • 00:00 - Wort chilled to 24 °C
  1. Fermentation
    Fill malt in fermentation bottle through a hop-filter
  • Gravity test result: 1.040
  1. Add 200 ml Yeast Munton’s Ale yeast
  2. Fill in 1st fertilization bottle

20 Feb 2018

  1. Transfer wort to 2nd fertilization bottle

  1. Gravity test
  • Gravity test result (FG): 1.009
  • => Alcohol By Volume: 4.07%
    • Original Gravity: 9.99 °P, 1.040
    • Final Gravity: 2.31 °P, 1.009
    • Apparent Attenuation: 77%
  1. Mix Priming Sugar
  • 150g sugar in 1l water
  1. Add 150ml of the priming sugar solution to the wort
  2. Transfer wort into bottles
