Dodano do wody RO:
- 5ml kwasu mlekowego 80%
- 4g epsom (Mg+2 SO4• 7H2O)
- 3g chlorku wapnia (Ca+2 Cl2• 2H2O)
- 9g kredy (Ca+2 CO3)
- 3g proszku do pieczenia (Na+ HCO3)

Modyfikacja: https://www.brewersfriend.com/mash-chemistry-and-brewing-water-calculator/?id=NMFZ8HV

Kleikowanie płatków jęczmiennych: 20min z 65st -> 63,5st.

Zacieranie w ok. 75st.
0min - pH 6
10min - pH 5,85
30min - pH 5,90
35min - dodanie 0,15kg jęczmienia palonego
40min - pH 5,87
45min - dodanie 0,25k pszenicy czekoladowej
65min - pH 5,86

Brzeczka po zacieraniu - 11,9blg.

Wysładzanie: 21,4l (22,7l gar) - 8,1 blg.
Po gotowaniu: 15,7l (17,7 gar) - 10,8 blg (0,3l straty)

Finalnie: 15,4l o pH 5,62 i 10,8 blg + dodano 5,4l wody (żywiec zdrój) = 20,8l z 8 blg.
