Brew Number 107

• Brew Craft's "Break & Enter" IPA (20915)
• Safale US-05 yeast

Kit contained

• 1.7kg Brewcraft Pale Ale
• 1.5kg Briess Munich Malt
• 2 x 150g cracked Crystal grain
• 25g Galaxy hops
• 25g Mosaic hops
• 11.5g Safale US-05 yeast

Brought out to 19L in Fermzilla. Recipe does not specify final volume but this gave a reasonable SG.

The yeast has an apparent attenuation of 78-82% If that is so the final gravity should be...

FG = (SG - 1000) * (1 - AA/100) + 1000 
   = ((1051 - 1000) * (1 - 80/100)) + 1000
   = 1010.2

Date	Measured SG	Temperature	Corrected SG	Brix	Notes
11/01/2020 17:00	1.047	39.0	1051	13.8%	Spunding valve set to 25 PSI
21/01/2020 09:30	1.007	19.0	1.007		Set to 2C for cold crash, spunding valve set to 10 PSI, chitosan added

Notes

• Yeast pitched at 39C
• Temperature set at 19C.
• IPA should have 2.1 - 2.6 volumes of CO2 which is 7-13 PSI at 4C and 22-30 PSI at 19C
