Brix showed a bit higher at 13.4 (13.0 would have matched 1.052)
But Brix was taken after putting yeast in, maybe that messed it up.
Had been fermenting at room temp, which was probably only about 10˚C, from 01/12/2016 to 06/12/2016. Then put on the heat pad until 10/12/2016. at this point 1.020. Put on the heat belt. (the mat was being used for bottle conditioning.
Bottled 13/12/2016, still on 1.020
Not sure why low attenuation. Low temp?
Bottled 28 x 500ml bottles with 5ml dissolved light muscavado from 92g. So 3.3g per bottle.
Bottled the remaining 8 bottles and the 2.4 litre jug with 1 teaspoon each.
