Labneh Strain Rate (Yogurt Weight to Final Yield)

2

Whole-milk yogurt — Starting weight; higher fat content (≥3.5%) gives creamier labneh

1

Labneh (strained yield) — ~50% of starting weight after overnight straining

1

Whey (drained off) — Reserve for bread baking, soup thinning, or ricotta production

Line a colander with a double layer of cheesecloth or a clean muslin cloth. Pour in yogurt, tie the cloth into a bundle, and suspend it over a bowl in the refrigerator. Strain for 8 hours for soft labneh, 12–24 hours for firm labneh that can be rolled into balls. Salt (1–1.5% of starting yogurt weight) may be mixed in before or after straining to draw out additional whey and season simultaneously.

• Salt the yogurt before straining: it draws whey more aggressively and seasons the labneh evenly throughout.
• Keep straining in the refrigerator (4°C) to prevent over-acidification, which would make the labneh sharp and grainy.
• Save the whey — it is rich in lactose and B vitamins; use it as the liquid in flatbreads or as a tenderising marinade.
• For perfectly uniform balls, chill strained labneh for 30 minutes before rolling, then coat in za'atar, sumac, or dried mint and submerge in good olive oil for preservation.
• If yield seems lower than expected, check that the yogurt has no added stabilisers (pectin, gelatin, starch) — these trap water and actually inflate final weight while degrading texture.

• Low-fat yogurt base

  Yield drops to 40–45% because less fat is present to retain structure; texture is tangier and less luxurious

• Sheep's milk yogurt

  Higher fat and protein raise yield toward 55–60%; flavour is richer and more complex

• Extended strain (48 hours)

  Yield falls to 30–35%; produces very firm labneh suitable for rolling in herbs and olive oil for preservation

• Room-temperature straining

  Faster whey release, 6–8 hours suffices; only suitable in cool ambient conditions (below 20°C) to avoid souring

• Greek yogurt as starting base

  Already partially strained; 4–6 hours produces firm labneh, yield closer to 70–75% of the starting weight

• Milk to Curd Yield for Hard Cheese (~10:1)

  Both ratios track moisture loss from a dairy base; labneh retains far more water than pressed hard cheese

• Brine Concentration for Cheese Salting (18–23% Saturated)

  Labneh balls preserved in oil sometimes pass through a brief light brine before oil immersion

• Rennet Dosage (per Litre of Milk)

  Labneh requires no rennet — acid coagulation from live cultures is sufficient, distinguishing it from true cheese
