Depends on what your location and budget is. Storing wine outside or at room temperature doesn’t age it the same way a wine cellar in France would. In general you want ~53-57 Fahrenheit and 50-80% humidity depending on what exactly you want to happen.
Unfortunately, simply digging a hole in your back yard only gets it to the average temperature of your area which may be quite different to that hypothetical wine cellar in France.
In the end keeping even a fairly large room at whatever temperature and humidity level you desire isn’t that difficult, assuming you have the space and budget.
