You're right !
The air column in the bottleneck act as a one-sideclosed pipe resonator. The peak frequency is the one of the quarter wavelength standing wave.
The formula used is :
Cair = 4 f0 (L + 0,61xD)
I was insired by this paper :
https://aapt.scitation.org/doi/10.1119/1.5145480
And of course, once the bottle is open and some wine has been drunk, one can use the formula of the Helmotz resonnator instead ! May be i will add it in a few days !
Here is a result with a test tube.
