  • How long does brown sugar last? The precise answer depends to a large extent on storage conditions - store brown sugar in a cool, dry area.
  • To maximize the shelf life of brown sugar, keep the package tightly sealed after opening.
  • To further extend the shelf life of brown sugar and to prevent it from hardening once opened, place sugar in a covered airtight container or cover original package with a heavy-duty plastic bag and seal.
  • How long does brown sugar last at room temperature? When properly stored and kept free from contaminants, brown sugar has an indefinite shelf life.
  • To moisten brown sugar that has hardened, place a cut piece of apple in the package with the sugar, reseal and leave overnight.
  • If hardened brown sugar is needed immediately, wrap the sugar with foil or plastic wrap and pound with a hammer.
