The past two beers I've made have had the same problem. My pre-boil gravity is spot on. My pre-boil water volume is spot on. My post-boil water volume is spot on. Yet my post-boil into-the-fermenter original gravity is low. Isn't that kind of impossible?
Here are the details today:
------------------estimated -------measured
pre-boil SG---------1.040------------1.040
pre-boil H2O vol----7.0 gal-----------7.0 gal
post boil SG--------1.049------------1.043
post-boil H2O vol---5.25 gal----------5.25 gal
all estimates provided by beersmith 2.0, all measurements cross checked between hydrometer and refractometer, post-boil SG taken form two independent samples.
What is going on? I'm going crazy over this!
