Inductor Shunt Capacitance

    I know that the there is some small capacitance between the windings of an axial inductor lets say, but how does one measure this? The inductor is a short on an LCR meter...

    An inductor is not a short on an LCR meter. If the meter is any good, it should be able to measure all 3 quantities for a real-world inductor. What meter are you using, and what value of inductor are you trying to measure?

    You can also use a DMM + Vector Impedance Meter to characterize the inductor's LCR values.

    Increase the frequency until the coil is capacitive. From the frequency where the behaviour changes, you can deduce the capacitance - provided the inductance stays constant, far from granted.
