The third one has started to clear, but when I took a sip - Sweet notes ! still on the dry side but a pleasant sweetness in there.
That is when I got the hydrometer out and sure enough 1030 !
Checked the other 2 and 0.997 !
Now these are all sugar heads containing whatever fruit I had picked when I made them.
The first has 11 lb fruit and 5 kg sugar in 25 litres
The second I think 7kg fruit (15.5 lb) and 5 kg sugar in 25 litres
And what I assume is the wierd one - 7 kg fruit brought to boil and simmered for a while, 5 kg sugar in 25 Litres water.
All have been fermented on the pulp and this afternoon, I was straining out the pulp ready to run them, when this anomaly appeared.
I know we have discussions about heat producing unfermentables when mashing beer - Is there any way that the fructose in the plums could be turned into unfermentables by the boiling / simmering process ?
