how long can you leave butter unrefrigerated
You can keep butter out of the refrigerator for about a couple of days if the temperature in the room is below 65 degrees Fahrenheit. The warmer the room temperature, the sooner you have to get the butter back into the refrigerator. Always keep butter in the refrigerator if you live in a very hot climate. Unrefrigerated Butter Butter can be kept unrefrigerated for several days, but conservative estimates put the shelf life of room temperature butter at one to two days, at most. The ambient temperature of the room will determine how quickly the butter spoils; keeping it at 65 degrees Fahrenheit or below is best.
