Brewday #17 – Moose Drool Clone

In this brew day I accomplished a much needed task and that was to carefully keep track of my water volumes.  Why?  So I could calculate my efficiency and get a better ability to hit both starting gravity (SG) and volume into my fermenter.

I accomplished the goal of water volume management by simply measuring how many inches are in a gallon in my brew pot (2″ per gallon) and taking into account my expected grain adsorption as well as boil off volume.

I ended up with 1.5 quarts loss on 5.156 pounds, or 0.3 quarts per pound, less than I expected.

On the flip side I ended up with a higher evaporation rate (1.25 gallons/hour) even with a slower rolling boil that I was getting inside.

These numbers will help in the future quite a bit, and now seeing my no rinse BIAB method efficiency of just 56%, I can plan my recipe’s for that value (or try another batch rinsing with ~1 gallon of water to see if there is an increase).

All in all a fairly good brew day, except for the whole leaf hops again.  This is the last time I use those (without a hop sack anyways).
