Wouldn’t the loss of cool air from opening the fridge repeatedly negate the benefit of doing this? Or would one simply remove multiple bottles at once strategically over time? I admit, this sounds like an interesting idea; just not sure what the “most-correct” strategy would be for extending food preservation.
As someome mentioned, the thermal mass of water is way higher than air, but also, this is the problem that deep freezers solve! Afaik, deep freezers open from the top meaning the cold air does not flow out when you open it. That saves effeciency on your heat pump.
Another neat thing you can do depending on where you live is set a timer on your deep freeze so it only turns on at night. This benefits you if you get charged electricity depending on the hour of the day, meaning you are charged nore during peak hours. Since the deep freeze has high thermal mass and low energy transfer, it stays cold all day.
not sure where you are from but there are also deep freezers that look like fridges.
they also don’t run the compressor the whole time, so there is no need to only ‘turn them on’ when electricity is cheap (which, from a european pov is all ghr time in thr USA). if they get above a certain threshold, they turn on and then off again when reaching the target temperature. that usually takes about 10 minutes. if you only turn it on at night it might be running way longer than when it’s on the whole time…
The thermal mass of the air is negligable in comparison to that of the bottles. Thats why generally filling your fridge with random stuff is actually beneficial because once they are cooled down it will decrease the loss of energy whenever you open the fridge.

“most correct” would be to never ever open the fridge.
Obviously as you need things in it, you’ll have to open it.

The most important thing is to keep your hands cold.
