- 3 - 5 year timetable based on cool temperatures, dark storage. May spoil as quickly as 3 months in hot temperatures.
- Store on an inside shelf, not the door, at 40°F (4°C) or below.
- Close the container tightly; dairy absorbs fridge odours.
- Pour what you need and return it to the fridge right away.
