Calcium and wine

Grapevines, too, need their calcium, and they share it with humans through wine. Soil rich in calcium, magnesium, potassium, and sodium makes for healthy vines. A grape can contain 14 mg of calcium. (Compare that with its 4 mg of vitamin C.)

Thus, grape juice contains calcium, and wine contains even more after the wine-making process. A clay-filtration step can add calcium, as can a finishing with calcium bicarbonate to soften an overly acidic cru. 

You can find 43 mg (between 1-4% DV) of calcium in a glass of wine.  This is about half the amount found in a glass of Gerolsteiner mineral water.  Since wine doesn’t contain any protein, however, it’s still not advisable to go pour yourself a bottle for dinner.  Alas!

    A fun post! Does it apply equally to red and white? Temple

      Yes, as far as I can tell, both red and white will have calcium. There may be slightly more in red because the calcium plays a role in development of healthy grape skin, and the red wine skins play a role in the processing.

    As previous farmers (when we were kids) we agree, although our farms were never grape farms. We are following you along, because Laura is working on her French and this would be a great idea for her to learn.

      Oui! Yes – it’s great to read the French part first, then check out the English translation when you get stuck! Thanks for noting that your farming experience backs up the hypothesis about wine….! Qu’est-ce que vous cultiviez?

        Right now, all we grow is tomatoes and green beans, but when we were kids, corn and soybeans. Raspberry, gladiolus flowers and farm animals of all kinds, cow, pigs, chicken,. . I think that is what you asked?
