The classication of numerous Galactic B[e] stars is hampered by uncertain or unknown stellar parameters. In addition, Herbig B[e] stars and B[e] supergiants, both surrounded by dusty disks, show many spectroscopic similarities. We use the 12C/13C ratio, which drops drastically during stellar evolution, and show that the appearance of 13CO band emission is an unambiguous proof for a supergiant nature.
