Notes

YEAST. Leftover from secondary fermentor from Robobrew Kolsch #1.

MASH. 21.5 litres. (to have adequate water for mash)
21.5l / 4.64kg = 4.6 litres per kg.
Normal ratio is 2.5.
Could have probably used less mash water (17.5) for a 3.77l / kg.
Change ratio for Robobrew next time.

TEMP. After sparge, temperature at 68C.
Time to reach boil = 1 hour 20 minutes.
SG with 28 litres = 1.036
