Sorry for the flippant answer.. but quite possibly you don't!
If your LO prefers bottles that are warm you may struggle getting him to take bottles that are cold.. same as a babe who prefers cool bottles might not want to take one that is warm.. they all have preferences..
If you really want your LO to take cold bottles rather than warmed ones you could try making the bottle a tiny bit cooler each day for a while so that your LO doesnt really notice the gradual change to cold bottles... and gets used to it slowly.
In my experience William would just not drink a bottle that was too cold for him when he was a tiny .. and still prefers them slightly warmed.. strange really as he will now drink cold water.. but not cold milk lol..
