15 l eau de rinçage, 18 l empâtage / Houblonnage à froid après 5 jours pour 1 semaine
Based on boiling 25.00 gallonsliters at 1.060 for 70 minutes, this will decrease your wort by 1.17 gallonsliters, bringing your after boil OG to 1.063. You were planning on an OG of 1.063 so you are right on track. Nice job!
