Notes

+20 L water inmaischen = 20 liter

11 liter maisch- & filterverlies + 11 liter spoelwater = 20 liter

-5 liter kookverlies = 15 liter
- 9 (5 bevroren + 4 koel) liter koelwater = 24 liter wort eind
  
  NOTITIES NA BROUWEN 23/sept/2018
  
  21 liter maischwater begonnen
  
  19 liter na maischen & filteren (spoelen met 11 liter), dus 13 liter verlies masichen en filter en spoelen en herverwarmen voor spoelen.
  
  Na koken ongeveer 15,5 liter.
  
  Koelwater 4 liter bevroren, 5 liter gekoeld. Was te weinig bevroren, want na smelten was temp nog circa 40 graden. Daardoor nog lang moeten wachten. Volgende keer voor deze verhoudingen minimaal 6 liter bevroren water gebruiken.
  
  Uiteindelijk in de ton lijkt t op 23,5-24 liter, wat wel het doel was. Maischen was niet helemaal volledig leek het na dat uur (beetje blauwe uitslag nog met zetmeeltest). Original gravity niet 1075 maar slecht 1064. Corrigeer met rekentooltje voor alcohol in refractometer en je komt op 1.020. is dus 6% alcohol ongeveer.
  
  Maischdikte van 2,56 liter/kilo was wel echt dikke pap, daardoor ook moeilijker maischen (roeren en temp stellen).
  
  NA 9 dagen was SG 1036. Via berekening was de bedoeling 1016...
