• 1 x Perle Hop Pellets 25g
• 1 x Magnum Hop Pellets 25g
• 1 x Safale US-05 yeast

Brought out to 21L in Fermzilla.

The yeast has an apparent attenuation of 80% If that is so the final gravity should be...

FG = (SG - 1000) * (1 - AA/100) + 1000 
   = ((1042 - 1000) * (1 - 80/100)) + 1000
   = 1008.4

Date	Measured SG	Temperature	Corrected SG	Brix	Notes
22/08/2020 16:00	1042	19.1	1042	11.8%
31/08/2020 21:30	1005	16.5	1004	6.2%	Cold crashed

Notes

• Yeast pitched at 23C.

• Used iSpindel3.
• Spunding valve set to 25 PSI (ale should have 2.3-2.6 volumes of CO2, used 2.45).
• ABV = 1.646 * RI - 2.703 * (145 - 145 / SG) - 1.794 = 6.8%
