Summer Milk Tips

While our special milk coolers do a lot to prevent milk from spoiling, remember to:

  • Place your milk cooler where the driver can see it but where it will be shaded from the early morning sunlight.
  • Refrigerate the milk as soon as possible.
  • Rinse out your milk cooler on a regular basis so it won’t smell.
  • Keep milk out of the light. Sunlight destroys vitamins.
  • Set your refrigerator to 35-40° F.

(The average shelf life of milk at 40°F is 10-12 days.)

Remember: FIFO First one in, first one out!

Be sure to rotate milk products in your refrigerator to reduce spoilage.

Winter Milk Tips

  • Bring milk in as soon as possible.
  • Keep the milk cooler close to the house.
  • Leave a towel next to the milk cooler and we will bundle it up after delivery.

If your milk freezes —
If the bottle is not broken, the milk can be thawed at room temperature. Unseal the cap and place the bottle in the sink, in case it leaks or spills. “Thawed” milk is perfectly safe to drink. Return the bottles to the refrigerator as soon as possible.
