We present a fiber-based method for generating vortex beams with a tunable value of orbital angular momentum from 1 to +1 per photon. We propose a new (to our knowledge) method to determine the modal content of the fiber and demonstrate high purity of the desired vortex state (97% after 20 m, even after bends and twists). This method has immediate utility for the multitude of applications in science and technology that exploit vortex light states.
