Brew Number 129

• Magrove Jack's Strawberry & Pear Cider (Brewfather version (total bodge))

Ingredients

• Juice concentrate
• Strawberry & pear flavouring sachet.
• 2kg Dextrose (kit only said 1kg but it was too low)
• 1 x M-02 cider yeast packets
• Sachet of Mangrove Jacks Liquid Finings

Process

• Dissolve sugar and syrup in hot water.
• Cool to ~40C
• Transfer to fermenter.
• Cooled to 20C and pitch yeast.

Note: in reality I had to transfer some back from the fermenter to dissolve the extra kilo of dextrose.

Ended up with 23L in 35L fermenter.

The yeast has an apparent attenuation of 95% If that is so the final gravity should be...

FG = (SG - 1000) * (1 - AA/100) + 1000 
   = ((1055 - 1000) * (1 - 95/100)) + 1000
   = 1003

Notes

• Yeast pitched at 20C.
• Temperature set at 20C.
• Used iSpindel4.
• Spunding valve set to 20 PSI (ale should have 2.3-2.6 volumes of CO2, used 2.0 to try and stop the iSpindel leaking).
• iSpindel leaked due to split lid, cable tied it on.
• ABV = 1.646 * RI - 2.703 * (145 - 145 / SG) - 1.794 = ??
• Grafana plot
• Brew Father batch
