The Auswine Forum

I recently opened a bottle of Pegasus Bay 2002 Pinot Noir (not an Australian wine I know but anyway...) And found on the bottom of the cork what appeared to be sugar crystals. Little roughly square whitish deposits. Is this a common thing to find? I've certainly not noticed it before. And is it sugar or something else?

The wine certainly wasn't affected, in fact it was a wonderfull drop. If anyone has tried it I'd like to hear what you thought.

Hi Gunmen

Potassium Bi-Tartrate is usually the cause of white or red crystal deposits. They are caused because the wine has not been properly stabilised. Shouldn't impact the flavour of the wine though.

thanks GRB for the info!!!
