If your wine is still producing a cap (grape skins) that means it is still fermenting. That cap usually gets punched down every 8 hours or so to improve extraction and to keep the skins moist. Once the cap "falls" the fermentation is likely complete. You can confirm with a residual sugar test (Clintest). Dry red wines should finish about 0.1 to 0.2 residual sugar.
Something is always fermenting....
