Hello all and thanks for reading. I am trying to determine why my first runnings are always so low and sparge volumes are so high. Forgive me for the Metric Units. Here goes:
We are brewing 37.8 Litres @ ~ 4.0% ABV
Pre-Boil Vol - 49.3 Litres
Total Grain Bill = 8.8 KG's
Mash Ratio = 3 litres/KG
Strike Water = (8.8 *3) = 26.4 Litres
26.4 Liters minus grain absorption (8.8 Litres) and MT deadspace (2 l) = 15.6 Litres
Pre - Boil (49.3) - FR (15.6) = 33 Litres of SParge.
SO, I end up sparging a lot, certainly to much. but my Mash ratio is already in the upper range of what I have mash volume for and certainly inside the typical range. I would LIke to get 50% of pre-boil volume from first runnings but even at 10.40 OG that is not achievable.
The obvious solution is to move to a 4-5 litre per KG mash ratio but that is far thinner then I want to go.
1) What mash ratio is typical for you to use?
2) where have i screwed this up?
Thank You
