If you use champagne bottles and you use a wire cage to fix the plastic caps (not sure what they are called ) there is no reason why the wine should end up inside your fridge rather than inside the bottle. Champagne bottles are designed to hold the pressure of sparkling wine (carbonated) and the wire ties - the cages - will prevent the caps from being pushed out by the pressure of the CO2. If you bottle wine after it has fermented but you have not allowed the CO2 to dissipate or you have not degassed the wine then your wine will be naturally carbonated.
