AI Overview
No, sugar does not expire or spoil as long as it is kept dry, because it does not support the growth of bacteria or fungi.
Shelf Life and Quality
• Indefinite life: Pure granulated white sugar lasts forever because it absorbs moisture and stops microorganisms from growing.
• Best-by dates: Manufacturers print a "best by" date of two years to measure peak quality and texture, not safety.
• Clumping: Over time, sugar can harden or form lumps if it touches the air or humidity, but it is still safe to use.

Agree. It lasts forever. I've had muscovado sugar in my cupboard for around 15 years! It has completely dried up and it's a large clump.
