I made a pretty big mistake this morning. I just bought some frozen
Sangiovese grapes and just this morning I added nutrient and pitched
the yeast. Yesterday I purchased the yeast and I recalled from the
Brehm website that they suggested a yeast, I think it was D10. So I
bought, and pitched, D47, yeast which is intended for Chardonnay.

What can I do if anything and what will happen to this wine?

I haven't visited this forum for a while, glad to see it is still
active and helpful.
