Will yogurt go bad at room temperature?
Keep it refrigerated after you bring it home from the store, and do not leave yogurt at room temperature for longer than two hours or one hour if the temperature is 90 degrees F or above. If left unrefrigerated longer, bacteria can start to grow. When stored properly, the shelf-life of yogurt is seven to 14 days.
What should the temperature be to make yogurt?
In winters, the room temperatures often fall below the required point to develop cultures for yogurt jars. When the temperature falls below 21 degrees (Celsius), one way to keep the pace going is to put the yogurt jars in a closed oven on a baking tray at a constant temperature.
How long is it safe to eat refrigerated yogurt?
