Living in earthquake, fire, mudslide, and potential zombie outbreak territory, I am generally well prepared. Besides the wall, a goldfish-filled moat, and Cuddles frolicking on a zipline I am also well-stocked with emergency supplies. Rice, beans, jerky, canned food, nuts, powdered egg, powdered milk, and UHT milk. A few hours ago, I inventoried my supplies and I found 4 quarts of aged UHT milk cartons. I was curious and opened one of them. More than 11 months past its best-by date the milk is still okay. The product was stored at 63 degrees F and 50% humidity. The tera pscks look unremarkable without bloating. I'm going to keep the other three quarts and I will open one every six months.
