Project Beer - Banana Exbeerience

Recipe source: https://brauerei.mueggelland.de/rezeptdetails/items/126.html

Description

The Banana Exbeerience is a pale wheat beer in the German way. In the glass, the beer should appear as a light and cloudy drink. The color should be around 8 on the scale from the European Brewery Convention (EBC). The taste has notes of banana and is very mild. It should be around the designated International Bittering Unit (IBU) of 12. The final volume of alcohol should be around 5.4% and therefore a nice drink to a nice meal.

  1. Milling
    • Crush Münchner Malt Type I
    • Crush Acidulated Malt
  2. Mashing
    • Measuring
      • Acidulated Malt 100g
      • Münchner Malt Type I 370g
      • White Wheat Malt 1800g

  1. Sparging
    • Sparge entire pot
    • Sparge a second time to get anything out of the mash
    • end up with 30 l (8 gal) of wort
  2. Boiling down
    • reduce volume of the wort to 6 gal
  3. Boiling and Chilling
    • Due to the wort volume problem we combined the 80min pre wort and the 70min cooking hops.
    • 3:55 pm - 70min left - add hops (Tettnanger)
    • 5:07 pm - 0 min left - Start Chilling
    • 5:15 pm - Chilling done 17 °C
  4. Fermenting
    • Original Gravity (OG): 1.031
    • Fill into fermenting vessel
    • Add Yeast
