Common questions
How long does sugar last at room temperature?
Indefinitely (18–24 months once opened) in a cool, dry pantry.
How can I tell if sugar has gone bad?
Throw it out if you see mold, a slimy texture, an off smell or an odd color. For anything perishable, go by the storage time rather than smell: bacteria that cause food poisoning don't usually change how food looks or smells.
