Potassium?

[johnsarris]

Do any wines contain potassium? If so, how much per (bottle, glass)? I have been put on a diet restricting potassium intake and want to know if wine is ok.
Thanks!

I think we shall need a chemist to get you a definitive answer.

I know that potassium tartrate (tartaric acid) is part of grape juice's natural component structure and that some of it remains in wine and forms part of wine's acidic back bone.

Small wineries used to administer sulfite doses in the form of potassium metabisulfite powder, but that practice should be all but dead by now. Sulfites are generally administered as a liquid gas.

Maybe Bucko can help here.

Bucko has a lie for every occasion. Actually I do know the answer to this one -- it has come up with my patients. Believe it or not, potassium is one of the principal trace components in wine. There is roughly one gram of potassium per liter of wine, or a mg/cc. In English measure, roughly 250 mg per 8 ounce glass of wine.
