According to the label on the back of the bottle, it has a "slight umami" flavor, but I personally felt a rich umami derived from rice (perhaps because the bottle had been open for a day). The sharpness is as you say. The word that came to mind was "authentic". It's good as a food wine, or a sipping wine on a long autumn night. Oh, it's wonderful.
