I have been using Parmalat milk for years, but it can get alittle pricey. The shelf life is one year unopened and must be refregerated up to 7 days after opening. the milk is heated to an ultra high temperature and is packaged in a special box to lock out the light and air.
Recently, I was at the Ft. Eustis, VA. Commissary and picked up a case of one quarts for $l.00 a box. This is great for keeping in the truck and for traveling. On a recent Elk hunting trip in Wyoming, the small 8 ounce boxes prooved to be invaluable in saving the water to mix instant dry milk.
