Not hitting the right OG
I´ve brewed several batches, but lately i havent been able to reach the right OG. Today I brewed an APA, here is the grain bill.
9pounds 6 oz 2-row brewers malt
13 oz caramel 60
12.3 oz munuch II
this was suposed to give me an OG of 1.055
But I ended up with 1.040
I think is one this factors. I´m gringing my grains in a old old corona mill. some time whole uncrushed grains, come through the top, it´s a small percentage but there are certainly some uncrushed grains, not even 5 %.
I´m probably sparging too fast. here is how im doing it: i use a 10 gallon igloo cooler, with cpvc on the bottom.
beersmith told me to:
add 13.68 qt of water 165° to achieve an 152° for 60 min.
then sparge with 5.85 gallons of water at 168°
after the 60 min. I drained the first wort, then added the sparge water all at once and drained it. I didnt keep time of how fast i was sparging but it was pretty fast:
could this be the issue or the mill, or both?
