• Mangrove Jack's Craft Series Rya IPA
• Mangrove Jack's Craft Series Pure Liquid Malt 1.2kg

Kit contained

• Rye IPA pouch
• 1.2 kg LME
• "Rya IPA" hops
• Mangrove Jack's US West Coast M44 yeast

Brought out to 18L in Fermzilla.

The yeast has an apparent attenuation of 77-85% If that is so the final gravity should be...

FG = (SG - 1000) * (1 - AA/100) + 1000 
   = ((1043 - 1000) * (1 - 81/100)) + 1000
   = 1008

Notes

• Yeast pitched at 23C.
• Temperature set at 20C.
• Used iSpindel3.
• Spunding valve set to 27 PSI (Ales should have 2.3 - 2.6 volumes of CO2, used 2.45).
• ABV = 1.646 * RI - 2.703 * (145 - 145 / SG) - 1.794 = 6.7%
