How Long Does Butter Last?
Signs Butter Has Gone Bad
- ⚠️ Rancid or sour smell
- ⚠️ Yellow or dark discolouration on surface
- ⚠️ Off or sharp taste
- ⚠️ Mould growth
Butter Storage Tips
- Keep butter away from light and heat on the counter
- Store in an airtight container in the fridge to prevent it absorbing other food odours
- Freeze excess butter sticks before the best-by date
- Unsalted butter goes rancid faster — refrigerate and use within 1 month
- Cut off surface discolouration — the inside is usually fine
⚠️
Unsalted butter is more susceptible to rancidity and should not be left at room temperature. Always refrigerate unsalted butter.
