I put the bottle in the night before last and let the internal temp stabilize. From monitoring last night, it appears to move between 56 and 57F, so it appears there is some temperature variation in the bottle. I'm going to check it again tonight to verify and then move it to the bottom shelf.

I've found a relatively cheap temperature controller ($26) that is used by beer home brewers. It has a built in 10 amp relay that may be OK for this fridge. It also has a cycle delay circuit that you can vary between 3 and 10 minutes, to protect your compressor from cycling on too quickly.

I would be happier if the relay was 15 amps as power draw on startup for a compressor motor can be quite high.
