So I just brewed my third batch in my Brew-Boss and my gravity readings are coming in consistently low and I can't figure out why. I am starting to think that the settings in my BeerSmith are off and feeding me the wrong estimates.
Anyhow, here is the latest recipe (its a big one). Beersmith has my estimated pre-boil gravity at 1.104SG and post-boil gravity at 1.123.
20 lbs Pale Malt (2 Row) US (2.0 SRM) Grain 1 81.6 %
1 lbs 8.0 oz Cara-Pils/Dextrine (2.0 SRM) Grain 2 6.1 %
3.00 oz Columbus (Tomahawk) [14.00 %] - Boil 90.0 min Hop 3 75.0 IBUs
2.50 oz Columbus (Tomahawk) [14.00 %] - Boil 60.0 min Hop 4 58.4 IBUs
1.20 Items Whirlfloc Tablet (Boil 15.0 mins) Fining 5 -
3 lbs Corn Sugar (Dextrose) [Boil for 15 min](0.0 SRM) Sugar 6 12.2 %
5.00 oz Amarillo [9.20 %] - Boil 10.0 min Hop 7 27.8 IBUs
3.00 oz Centennial [10.00 %] - Boil 5.0 min Hop 8 10.0 IBUs
2.00 oz Simcoe [13.00 %] - Boil 5.0 min Hop 9 8.7 IBUs
1.0 pkg California Ale (White Labs #WLP001) [35.49 ml] Yeast 10 -
0.60 tsp Yeast Nutrient (Primary 3.0 days) Other 11 -
2.00 oz Amarillo [9.20 %] - Dry Hop 7.0 Days Hop 12 0.0 IBUs
2.00 oz Centennial [10.00 %] - Dry Hop 7.0 Days Hop 13 0.0 IBUs
2.00 oz Simcoe [13.00 %] - Dry Hop 7.0 Days Hop 14 0.0 IBUs
Started with 9 Gallons in the pot. Brought it up to 152*. Added my grains and mashed for 60 minutes at 152*. Then mashed out at 168*. (1.065 SG according to my refractometer) Removed grains and increased to a boil. Then 90 minute boil with hop additions as prescribed. At "flame"-out, I whirlpooled for about 15 minutes while cooling down to around 90* and then switched the whirlpool attachment to the fermenting bucket and filled it up. Final temp was 75* and the SG measured at 1.100. Ended up with around 5 gallons in the bucket so topped off with one more to get me to 6.
Pitched a pretty large starter last night and this morning, it was just about ready to blow it top so I switched to a blow-off tube. So its fermenting well.
Any thoughts? I know that there is no shortage of opinions here so I would love to know what you guys think. Personally, I am about ready to upgrade to the COFI filter and see if that helps.
