I brewed a hefeweizen today with a target initial gravity of about 1.050. It was an extract brew (6 lbs LME) with about 8 oz of carapils steeping grains. I ended up with about 5.5 gallons in the fermenter. However, when I took the initial specific gravity it was much lower than I was expecting coming in at 1.041 at 64 degrees Fahrenheit.
Is there anything I could or should do at this point to raise the gravity? Is this something I should even be worried about?
thanks, Paul
