I am unreliable informed [*] that in the old days beekeepers would use the ‘tailings’, the honey that could only be extracted by washing the wax through with water after you’ve extracted the bulk of the honey and put it into jars, to make mead with. So that’s what I’ve done. Two demijohns worth.
I’ll report back in a year or two and let you know if I have drinkable mead or not.
[*] ie I read it on the internet somewhere.
