How long does Leben last and how should it be stored?
Keep leben (laban) in the fridge at 4 C (40 F) or below. A sealed store-bought carton is good until the date on the label; once opened, or if homemade, plan on roughly 1 to 2 weeks, tasting and smelling before use. Throw it out if you see mold, pink or gray patches, or it smells rotten rather than pleasantly sour.

How long does leben last in the fridge?
It depends on whether it is store-bought or homemade. For a sealed commercial product, the printed date is your guide, and the maker’s storage instructions come first. For homemade laban, one Lebanese cooking site gives two figures: about 1 to 2 weeks on its recipe card, and 2 to 3 weeks in its text, kept at or below 40 F (4 C) in a clean airtight container. The same page notes that 2 to 3 weeks is a relatively long time for homemade yogurt, so the shorter range is the safer one to plan around.
What is leben, exactly?
Leben or laban is a general name for soured, yogurt-like milk in parts of the Middle East and North Africa. The word is used for somewhat different products in different places, some thin and drinkable, some thicker. Because of that, always follow the pack or the recipe you used, not a single number.
How should you store it?
- Cold and steady: keep it in the main body of the fridge, not the door.
- Covered: use the original lid or an airtight container so it does not pick up fridge smells.
- Clean spoon every time: a used spoon adds bacteria and shortens its life.
- Away from the counter: do not leave it out for long periods, especially in warm rooms.
How can you tell it has gone bad?
- Any mold, or colored patches (pink, green, gray, black).
- A smell that is rotten, yeasty or like nail polish, not just tangy.
- Bulging or swollen packaging.
- Unusual slime or a very fizzy texture you did not expect.
It naturally gets tangier the longer it sits, and a little watery liquid on top is normal separation. Stir it back in. Sourness alone is not spoilage, but if you are unsure, discard it.
Can you freeze it?
We found no reliable guidance, and texture usually suffers when cultured milks are frozen, so we do not recommend it.
Who should be extra careful?
Homemade fermented milk made from raw milk carries more risk than pasteurized. People who are pregnant, elderly or have weakened immune systems should follow their health authority’s advice on raw dairy.

How long does homemade laban last?
About 1 to 2 weeks in a cold fridge is the safe plan. One recipe site says up to 2 to 3 weeks, but notes that is long for homemade yogurt.
Does leben go bad?
Yes. Mold, colored patches, a rotten or yeasty smell or a swollen pack mean throw it out.
Is leben the same as buttermilk or yogurt?
Not exactly. The name covers several soured milk products depending on the country, so check the label.
