I have some particularly promising white wine(Schonburger)which tastes
beautiful now.The grapes were harvested in October 2007,racked in
November and 30ppm sulphite added.It is now clear in a 1 gallon
glass demijohn and I wish to make sure that it lasts into the
summer.Will adding some more sulphite (another 30ppm) protect it,and
should I put it somewher cool to keep it in best condition.I live in
England (we do make good wine here!)and the summer temperatures rarely
exceed 80F.Should I also keep it out of the light.I know that this is
a small quantity,but I do wish to develop good practise.
