Very low FG

Postby helloworld » Thu Feb 05, 2015 10:06 am

My latest IPA came out very low: 1.005 (!). I'm not sure how this happened. I'm not really worried about it but I am curious if anyone has an idea on what happened. It was 13 # 2-row and 1 # of C15. 1.5 Liter starter (used JZ's calculator) w/ temp control.

One thought was that when I used the JZ calculator I set it to pitch into 5.5 gallons. I ended up pitching into probably just under 5.

EDIT: Left out some details. White Labs 001, mash of 144 for 90 minutes. Target was 152 but it was a cold morning and I missed it by a long shot.

Most likely this is why it finished so low (probably very dry as well). The low and long mash temp and time will produce more fermentable sugars. My Belgians are always mashed for 90 minutes at 148*F and always end up around 1.005/1.007 and 9%+ ABV.
