.036g water lost per hops oz
18% of pre-boil volume lost per 60min of boil
4% of post-boil volume lost when chilling from boil to pitch temp.

Assuming 13.69 lb grain, 3 oz hops, 9.25 g total water
pre-boil target 7.54 g Grain loss 1.71 g
after hops loss 7.43 g Hops loss 0.11 g
post-boil 6.09 g Boil loss 1.34 g
post-chill 5.85 g Chill loss 0.24 g

** Goal is 5g net for Keg + .5g for 6-bottles AFTER fermentation.

Notes

DESIGN POINTS :

  • Considered decocting the mash, but opted not to safe effort (ha) and also didn't want this to end up too much like a dunkel

    KEY STEPS:
    1) Target water profile is Munich (Dark Lager), which was hard to achieve without slaked lime. Goal pH is 5.3.
    2) Two-step mash schedule:
  • 30-minute protein rest at 122F
  • 60 minutes at 155F (bag not basket to avoid scorching)
    3) Add Fermcap prior to boil.
    4) Reyhdrate yeast (see below).
    5) Add Whirlfloc near boil end for clarity.
    6) Ferment at 55 ºF for 3 to 4 weeks.
    7) Perform diacetyl rest since using Lager yeast.
    8) Add PMB when kegging.

    Source: https://fermentis.com/en/product/saflager-w-34-70/#:~:text=② With prior rehydration:,cream into the fermentation vessel .

    1) Sprinkle the yeast in minimum 10 times its weight of sterile water (not RO or distilled) (~1cup since 2 packets) or boiled & hopped wort at 15 to 25°C (59°F to 77°F).
    2) Leave to rest 15 minutes
    3) Chilling for 15 minutes to get close to 54F
    4) Gently stir and pitch the resultant cream into the fermentation vessel.


    FERMENTING / KEGGING

    Ferment at 55F until hitting FG (watch the TILT !)
    Closed transfer to keg and lager in keezer ON CO2 for 4 weeks.
