Efficiency Specifics
Recipe Efficiency Setting: 70 %

With sparge water, mash water, additional infusions, vessel losses, top-up
water and evaporation rate recorded in the Water Needed Calculator:

Target Volume (Gal): 14.44      
Estimated OG: 1.040 Plato: 9.99

Raw Pre-Boil Targets - only targeted volume/gravity and evaporation
rate taken into account:
Target Volume (Gal): 12.31      
Estimated OG: 1.047 Plato: 11.65

Post-Boil Targets:
Target Volume (Gal): 10.00      
Estimated OG: 1.058 Plato: 14.21

Recorded Actuals - Measurement Taken In Kettle:
Recorded Volume (Gal): 12.50      
Recorded OG: 1.048 Plato: 11.83

At 100 percent extraction from the maximum mash potential:
Total Points: 82.45
Points From Mash: 82.45
Points From Extract/Sugar: 0.00

With the recipe efficiency setting, you should have achieved:
Total Points: 57.72
Points From Mash: 57.72
Points From Extract/Sugar: 0.00

Actuals achieved were:
Actual Points From Mash: 59.56
Actual Mash System Efficiency: 72 %


Fermentation Specifics
Pitched From: Starter
Amount Pitched: 24 OZ
Lag Time: 5.00 hours

Primary Fermenter: Stainless Steel
Primary Type: Closed
Days In Primary: 14
Primary Temperature: 68 degrees F

Original Gravity: 1.055 SG 13.56 Plato
Finishing Gravity: 1.017 SG 4.42 Plato



Mash Notes
Temp reached 171' during sparge. Is this going to cause astringency?


Fermentation Notes
On 10/2 the SG seemed to start rising. I am assuming this has something to do with the dry hopping, but I have nevr seen this before. FG taken to be at lowest measured.
