Fermentation on Rocks?
Most vineyards pull up stones and toss them aside, leaving the soil easier for the vines to burrow into. Left in place however, the roots of the vines (which are incredibly strong) would have broken through the rocks, absorbing their minerality into the fruit. By placing the rocks into the fermentation vessel, you give the wine an opportunity to take into itself what it was deprived of by having it prematurely removed.
