How long does syrup last in the freezer?

Freezing syrup is not recommended — it loses too much texture or quality. Keep it refrigerated or in the pantry instead, as shown in the table above.

How long does syrup last in the fridge?

Unopened syrup keeps for about 4 weeks in the fridge. After opening, use it within about 4 weeks.

How can I tell if syrup has gone bad?

Off, stale, or rancid smell (nuts and fats inside can turn). Mould, stickiness, or an unusual texture. A white 'bloom' on chocolate is harmless, but discard anything mouldy. When in doubt, throw it out.

Signs syrup has gone bad

Off, stale, or rancid smell (nuts and fats inside can turn).
Mould, stickiness, or an unusual texture.
A white 'bloom' on chocolate is harmless, but discard anything mouldy.

When in doubt, throw it out — the cost of a spoiled meal isn't worth the risk.

Best way to store syrup

Keep sweets in a cool, dry place in airtight packaging. Honey is essentially shelf-stable — if it crystallises, gently warm it. Chocolate keeps best somewhere cool and dark, not the fridge, to avoid sugar bloom.
