How Long Does Tahini Last?
Paste made from ground sesame seeds, used in hummus, dressings, and sauces.
The Short Answer
Tahini lasts 180–365 days in the refrigerator when stored properly at 40°F or below. For longer storage, tahini can be frozen for 6–12 months while maintaining good quality. At room temperature in the pantry, expect 120–180 days under normal conditions. These times are based on USDA food safety guidelines and assume proper storage conditions.

Oil separation in tahini is completely normal, not a sign of spoilage. Think of it like natural peanut butter. Stir it well before using. If the oil looks dark or smells off, that is when you should be concerned.
How to Store Tahini
Store unopened tahini in a cool, dark pantry. After opening, you can keep it in the pantry for a few months or refrigerate for longer shelf life. Oil separation is normal; stir before using. Refrigeration makes it thicker and harder to stir but extends freshness.
How to Tell if Tahini Has Gone Bad
Look for these signs that tahini has spoiled: bitter or rancid taste, off smell, mold around the cap or on the surface
The Professor's rule: When in doubt, throw it out. No meal is worth food poisoning.
The Bottom Line
Properly stored tahini stays safe for 180–365 days in the fridge. Always store in airtight containers, refrigerate within 2 hours of purchase or preparation, and trust your senses. If something looks, smells, or feels off, discard it regardless of how many days it has been. Freezing is always an option if you will not use it within the refrigerator window.
Frequently Asked Questions
Not strictly, but refrigeration extends freshness significantly. In the pantry, opened tahini lasts about 4-6 months. In the fridge, it lasts up to a year. The trade-off is that refrigerated tahini is thicker and harder to stir.
