Choosing an undercounter wine fridge will give you a greater range of placement options, but before you just plug it in, think about where it makes sense in your kitchen. Many people choose a place adjoining entertaining spaces, so sometimes the outward-facing side of a kitchen island works well. However, be mindful that UV light can impair the flavour of your favourite wines, so avoid a spot that gets a lot of sun.
To get the best from your wine fridge and ensure the internal temperature is as constant as possible, it should be installed in a room where the temperature is 22–25ºC/71–77ºF. Above and below these temperatures will make it harder for the fridge to regulate itself, meaning it uses more energy in the process.
