We prove that for generic geometry, the curl-eigenfield solutions to the steady Euler equations on $\mathbb{R}^3/\mathbb{Z}^3$ are all hydrodynamically unstable (linear, L2 norm). The proof involves a marriage of contact topological methods with the instability criterion of Friedlander and Vishik. An application of contact homology is the crucial step.
