Shelf Life of Ghee vs Butter — How Long Each Really Lasts

Why ghee outlasts butter

Butter is roughly 80 percent fat, with the rest mostly water and milk solids. Water and milk solids are what bacteria and mold need to grow, so butter spoils fairly quickly at room temperature. Ghee is made by heating butter until the water evaporates and the milk solids separate and are strained off. What is left is almost pure butterfat, with very little water. That is why ghee can sit in an Indian kitchen for weeks without spoiling.

Shelf life of butter

Unopened butter usually carries a best-before date of a few months when kept refrigerated. Once opened, it keeps well in the fridge for about one to three months, and much longer in the freezer. Salted butter keeps a little longer than unsalted. At room temperature, butter in a covered dish is fine for a day or two in a cool kitchen, but it will start to sour faster in warm weather.

Shelf life of ghee

Unopened, well-made ghee typically keeps for about 9 to 12 months in a cool, dark place. Once opened, ghee keeps about three months at cool room temperature if you always use a clean, dry spoon and keep the lid closed. In the fridge, opened ghee can keep for six months to a year. It will harden in the fridge, but softens again at room temperature.

How to tell if ghee or butter has gone bad

The main way fats go bad is rancidity, when the fat oxidizes. Rancid butter or ghee smells sour, stale, or like old crayons or paint, and tastes bitter. Mold, white or green spots, or a sour smell in butter mean it should be thrown away. Ghee that has picked up water from a wet spoon can grow mold too. If you are unsure, throw it out.

Storage habits that make both last longer

Keep both away from heat, light, and strong smells. Always use a clean, dry spoon in ghee, because water is the main thing that shortens its life. Buy ghee in a size you will finish within a few months of opening, or keep a small jar out and the rest in the fridge.

Frequently Asked Questions

Which lasts longer, ghee or butter?

Ghee lasts much longer. Removing water and milk solids leaves almost pure butterfat, which resists spoilage. Opened ghee keeps about three months at room temperature, while butter needs the fridge.

Does ghee need to be refrigerated?

No, not if you use it within about three months and keep it sealed, cool, and away from water. Refrigerating extends its shelf life to six months or more.

How do I know if ghee has gone bad?

Rancid ghee smells sour, stale, or paint-like and tastes bitter. Mold or an off smell means you should throw it away.
