You leave it at 70 or above (room temp) until it's done carbing and conditioning. WHich is usually 3 weeks, but may be longer. SO at 3 weeks you take a bottle abd put it in the fridge for at least 24 hours, preferably more. Then you check it for taste and carbonation. If its to yourf liking you put as many bottles in the fridge as you want. You don't have to chill them all. You can store the rest at room temp for as long as you want to, chilling only as many at a time as you want. I generally only have 6 of any given beer in the fridge at one time, replacing them as I pull them.
But if it's not carbed or tastes to your liking yet, leave them warm and check them in another week.
