You can start by using cooler box, if you don't want to buy wine fridge or modify a regular fridge as yet.
It is more work, depend on the temp where you put your cooler box.
All you need is a cooler box and ice blocks, I use square milk bottles with water inside and freeze.
You may need to change the ice blocks 1-2 times a day. On a super hot day, I needed to change them twice but when I wheeled my cooler box inside an aircon room, only once every 36 hours.
I did this for a few months until it get too tedious.
