Add wine; simmer until absorbed, stirring often. Add warm broth mixture 1 cup at a time, allowing each addition to be absorbed before adding next and stirring often, until rice is tender but still firm to bite, about 20 minutes.

Serve immediately in warm bowls, passing additional Parmesan cheese alongside.
