Off grid, um "soft drink" cooler ;)

There's only one lemonade shop in the village - its got a bit of an atmosphere sometimes...

I keep cans in the back of the shed in a cupboard draw and they stay cold even in this hot summer we have but I also have a USB Mini Fridge and a charging battery that I can plug it into to make it even colder.

Look on Amazon for a Fridge-Scenstar-Cooler-Beverage-Refrigerator

you get that when people drink a lot of English lemonade in one place. Opening a window helps...

I don't suppose your plot has a stream by/in it does it? if you could fashion a basket that could securely hold the lemonade and sit in the water that would keep them cool.

Unless there's power or chemical reaction involved then there's a limit to how much you can cool something which will be the ambient temperature.

When something wants to change state (e.g. liquid to gas/vapour) it needs to transfer heat between itself and something else. It also needs a reason to want to change.

Water needs to transfer alot of energy to change temperature (it takes less energy to heat concrete 1 degree than a comparable amount of water).

The best semi off grid method is a bag of ice and some salt. The salt makes the ice want to melt quickly which then needs to suck the heat out of anything it's in contact with. Used to make icecream this way and it's so effective it has been known to make Newcastle Brown Popsicles.

Evaporative is your next best bet. This is what the charcoal cooler done as well as things like canvas bags soaked in water. The key with these is having a draught so the warmed water vapour can be moved away.

Half glazed earthenware jars used to be used to keep food cool. The unglazed bottom half would be buried in damp soil in the shade and the moisture would wick away the heat (unglazed, I expect, so the moisture can get into the pottery and cool the entire surface better).

I suspect that the outer jar in your set up might actually act as an insulator reducing the loss of heat to the environment.

You could just pop the cans/bottles into a plastic bag and tie a rope to that before dropping it into a full water butt. The amount of BTUs needed to raise all that water one degree usually means that if your butts shaded it should be nice and cool.

I had high hopes, but it seems it would only hold one can of lemonade... I might need to start drinking irn-bru

Most of my barrels hold various concoctions... perhaps I need one with nothing but cool refreshing water as god intended... for cooling other refreshments. Might be the easiest way to go... though I've got a couple of car batteries a solar charger and an inverter looking for something useful to do.
