Tahini paste is made from sesame seeds and has a long shelf life. It is difficult to determine how long it will last exactly, but it typically lasts for 1-2 years. Once opened, it should be refrigerated and last 5-6 months.

Does Tahini Go Bad?

A “best by” date on a jar of tahini is a rough guess of how long the product will stay fresh. 

It can last a few months longer than the date, but it is hard to say how long it will last.

The process of quality degradation speeds up a bit once you open the jar. But the paste should keep good for at least a couple of months or until the printed date, whichever comes later.

How Can You Tell If Tahini Has Gone Bad?

Trust your sense of sight, smell, and taste and you should be able to tell apart a jar of tahini that has turned and one that is still good to use.

Rancid Smell

The oil that floats at the top of a jar of Tahini is supposed to preserve the underlying paste. However, when the condiment is exposed to oxygen, the oil will oxidize and develop a rancid smell. Look out for a metallic, bitter, or soapy smell, as this could be a sign of rancidity.

Unpleasant Taste

If you want to ascertain the freshness of your tahini paste, you can taste a small scoop. Unless there is visible mold, tasting tahini that you suspect has gone bad will not necessarily harm you. 

Check for a petrol-like taste or the taste of overstayed cooking oil and discard if this is the case. You definitely do not want to spoil your recipes with an off-tasting condiment.


Tahini is a key ingredient in many Middle Eastern and Mediterranean dishes, such as hummus and baba ghanoush. Tahini that has lost its freshness will lose its smooth consistency and begin to harden. 

You will mostly notice this with paste that has stayed too long or has been exposed to the elements. This is why it is important to tightly seal your jar of tahini after every use. You should also try to consume your sesame paste within the shortest time after opening the jar.


Mold on food is never a good sign. The oil in Tahini indeed makes it difficult for mold to grow in there but this does not completely rule out the possibility of mold growth. In particular,

check around the lips of the jar where it is exposed to air and moisture, which are the perfect conditions for mold growth. 

Do not be tempted to just wipe the mold spores and continue using the Tahini. It is best to be safe and throw away that moldy jar. Tahini is not the cheapest condiment but you are better off not consuming mold-contaminated food.

Here Are Some Smart Tahini Storage Tips

Pantry Storage

Many people like to refrigerate tahini, and although there is nothing wrong with this, the best place to store it is in a pantry or kitchen cabinet. Tahini requires a cool, dry place, away from direct sunlight, heat, and humidity. 

You should always keep an eye on the best-by date and expiry date if your particular brand has one. Be sure to keep your jar tightly sealed to prevent oxidation as this can lead to rancidity.


As we mentioned earlier, tahini has a relatively long life so it is not necessary to store it in the refrigerator. However, if you have homemade tahini at hand, we recommend refrigerating right away and consuming it within a few days. 

Refrigeration might be a good choice if you live in a warm climate or during the summer. If you choose to go this route, be sure to tightly seal the jar before sticking it back in the fridge. Leaving the cap to lose will let in moisture and increase the risk of mold growth.

If you open a jar of tahini and detect a rancid or unpleasant odor, it’s best to discard it to avoid any potential food safety issues.

Is Tahini Supposed To Be Bitter?

while others are milder. If you are unsure about the taste of particular tahini, it is best to start with a small amount and add more to taste.

How Do You Get Rid Of The Bitter Taste In Tahini?

I bought some hulled sesame seeds and toasted them lightly. That came out pretty well. They were crunchy and tasted great.

It was late, and I didn’t want to make noise using the Ninja blender (like a Magic Bullet), so I put the toasted seeds in the plastic cup/ container that is used with the Ninja blender and screwed on the cover. 

I left it on the counter overnight. The next morning, I unscrewed the top of the cup and smelled the seeds – they had kind of a rancid odor. But I shook a few out to taste them, and they tasted fine. I put some in my oatmeal, and they were great. 

I Don’t Know Why They Smelled Funky.

The person made tahini by blending seeds in a Ninja blender and adding olive oil to make it into a liquid. It is now a thick liquid that can be poured but has a bitter taste.
