SUGAR, GRANULATED (WHITE) — UNOPENED OR OPENED PACKAGE
The precise answer to the question “How long does granulated white sugar last?” depends to a large extent on storage conditions — when properly stored and kept free from contaminants, granulated white sugar has an indefinite shelf life.
To maximize the shelf life of granulated white sugar, store in a cool dry area and keep tightly sealed after opening.
To prevent granulated white sugar from hardening once opened, place sugar in a covered airtight container or cover original package with a heavy-duty plastic bag and seal.
