Notes

Yeast attenuation appears to be 80% or better, as per iSpindle data points. If validated on completion by hydrometer then adjust recipe for lower target abv of 4.5 and higher attenuation through custom value.

Resolve "iSpindle 1" battery issue where charge depleted to less than 50% in two days
