21 litres of water, 3g gypsum and 1 campden tablet
mash in at 67 (from around 73 strike water)
ph of 5.65 initially, added 4ml of CRC
Ph wort after adding acid (beginning of the mash): 5.2
Ph wort after mashing is done (1hour): 5.36
------
GRAVITY:
gravity of sparge water: GSW=1.010 at 65°C
(sparge water initial temperature 76°C, 10L)
gravity of mash wort before sparge:GMW=1.054 at 54°C
Gravity pre-boil of wort mash + wort sparge: GPB=1.047 at 55°C
GRAVITY corrected by temperature:
GSW=1.026
GMW=1.065
GPB=1.058
Calculated to be 73% efficiency
gravity post boil is 1.070. it was 24 litres in the pan and then around 22 litres in the fermenter.
used 2 packs of yeast (conical flask had been sanitised with tap water star san and was cloudy)
Final Gravity: 1.14
