Notes


Salts added to mash water only (5.68 gal)


Target mash water (mg/L):
Ca+2 - 65
Mg+2 - 2.5
Na+ - 15
Cl- - 100
SO4 - 33


~17ml Phosphoric acid to acidify ~15 gal sparge water

Step Mash

10 min. 113f - 2.88 Gallons @ 127.7 °F (.72qt/lb)
15 min. 136f - 1.1 Gallons @ boiling (1qt/lb)
50 min. 149f - 1 Gallons @ boiling (1.24qt/lb)
10 min. 156f - 0.7 Gallons @ boiling (1.44qt/lb)
5.68 gal total mash water, 15gal sparge
Fits in a 10 gallon mash ton

Thoughts:
Ideally want a thick mash (0.8-1qt/lb) for the protein rest. Could skip the first step.
Could do an iodine test and shorten the saccharification rest



fermcap to prevent boil over
whirlfloc in last 10-15 min
house saison mixed culture
dry hop if you want
