I over sulphited a gallon of black currant wine to cure an infection. It
seems to have worked, the wine tastes great, except for a soapy after
taste. I decided to leave it for a year to blend with next years batch.
Its kept in the coldest part of my flat (averaging about 14C) with a few
other wines and I check them every few days. With in a space of 2 days,
the wine suddenly dropped a white, cloudy sediment, about 1/4cm thick. I
haven't tasted it yet, I don't want to move the bottle until the
sediment has compacted a bit. Any suggestions as to what this might be?
Is it sulphates dropping out of the wine?
