Brew Number 114

• Casey's "American Pale" Ake fresh wort kit
• Morgan's American Ale Yeast

Kit contained

• 16L fresh wort

Brought out to 20L in Fermzilla.

The yeast has an apparent attenuation of ??% If that is so the final gravity should be...

FG = (SG - 1000) * (1 - AA/100) + 1000 
   = ((1045 - 1000) * (1 - ??/100)) + 1000
   = 

Date	Measured SG	Temperature	Corrected SG	Brix	Notes
29/06/2020 17:00	1039	25.6	1040	11.8%	Probably should have done 19L
04/07/2020 15:30					Dry hopped with 40g of Chinook
06/07/2020 14:30	1004	19.1	1004	5.8%	Cold crashed to 2C

Notes

• Yeast pitched at 25C.
• Temperature set at 20C.
• Used iSpindel3.
• Spunding valve set to 27 PSI (stout should have 2.3-2.6 volumes of CO2, used 2.45).
• ABV = 1.646 * RI - 2.703 * (145 - 145 / SG) - 1.794 = 6.2%
