This contribution combines a relatively comprehensive review of the spectroscopic study of the individual component stars and their associated disks in young binary systems, outlines the need for more in-depth studies, and previews the results of a high-spectral and high-angular resolution survey of 
100 young binaries located primarily in the Taurus and Ophiuchus star forming regions. Observed spectra, synthetic spectral analysis, and preliminary outcomes for 3 systems are presented, illustrating the power and potential of adaptive optics-fed, high-resolution, infrared spectroscopy for our understanding of the dynamical and physical properties of young binary stars and their circumstellar disks and environments, especially when combined with ancillary data from ALMA, K2, TESS, and other facilities. This new survey will deepen our understanding of disk evolution and planet formation in close binaries and, more broadly, will provide clues to disk dissipation processes in both singles and binaries.
