So the skins, seeds, pulp, probably some stems and other debris are all mixed into your fermenting wine. When the yeast are active, all the carbon dioxide (CO2) they produce is rising to the surface pushing those solids up with it. They collect on the surface, forming a cap. The whole point of putting grape skins in your must is to extract beneficial compounds from them, and this can&#8217;t happen while they&#8217;re out of contact with the fermenting wine. Also, yeast have no access to these solids and can&#8217;t crowd out other microorganisms, leaving the cap open to infection.<br \/>\n<br clear=\"all\" \/><br \/>\n<img decoding=\"async\" src=\"\/pic\/20071017 punching down the cap.jpg\" alt=\"Using a long handled spoon to punch down the cap of this fermenting Merlot wine on 10\/17\/07\" title=\"Punching Down The Cap on 10\/17\/07\" vspace=\"10\" \/><br \/>\n<br clear=\"all\" \/><br \/>\nYou can see the solution in the above photo, where I&#8217;m  physically submerging these solids with a long handled spoon.
