I brewed my first all-grain batch last Sunday (3/2), a lawnmower IPA, and it is currently sitting in my temp controlled chest freezer in the carboy. The original gravity was 1.044 and after taking my first gravity reading last night (3/9) the hydrometer read 1.014 (67%). I would always hit 73-75% when brewing IPAs with extract, using the same yeast, US-05, and that number would usually be reached by this time. Here's a breakdown of the brew:
3 Gallon final volume into 3 gallon carboy
5.5 #'s of 2 row
.25 #'s of carapils
.25 #'s of crystal 20
Mashed at 149 for 90 minutes
61% brewhouse efficiency
1 oz centennial at 60
1 oz centennial at 30
1 oz centennial at FO
Pitched full packet of US-05 at 60 degrees and shook the carboy for a few minutes, maintained a temp of 63F for first 5 days and have bumped it up to 64F since. I had a very strong fermentation for the first 4 days, blow off tubing utilized. I don't know if it indicates anything but the krausen is still nearly into the neck of the carboy. My concern is the current pace of the fermentation. I was hoping and expecting 80% attenuation as the mash was done at 149. Is there anything you can see that I may have overlooked that would cause such a low attenuation? If not is there anything that could be done to reach my expected attenuation rate?
Thank you in advance for any responses!
