How to Make Greek Yogurt at Home: Step-by-Step (With Straining Times)

What You Need

Greek yogurt is regular curd with the liquid whey strained out. That single step — straining — transforms runny dahi into the thick, creamy, protein-dense yogurt you see in stores at Rs 60–80 for a 400g tub. And those store-bought tubs almost always contain stabilisers, thickeners, and preservatives to extend shelf life.

When you learn how to make Greek yogurt at home, you skip all of that. Your version has one ingredient: curd. The result is fresher, thicker, and costs a fraction of what Epigamia or Milky Mist charges.

Here is what you need:

1. Thick, well-set curd (dahi)

• Homemade curd — the best option. Use full cream milk (Amul Gold or equivalent) and set it properly. If you struggle with inconsistent curd, an automatic curd maker maintains the right temperature through the fermentation cycle and produces thick curd every time.
• Store-bought curd — Amul Masti full cream dahi or Mother Dairy full cream dahi. Both work well. Avoid low-fat or "slim" variants — they produce thin, watery Greek yogurt with poor texture.
• What to avoid: Watery curd, sour curd (over-fermented), or curd that has already separated. If the curd has visible water pooling on top before you start, it was not set properly and will yield very little Greek yogurt.

2. A strainer setup

• Dedicated yogurt maker — a container with a built-in mesh strainer, lid, and outer vessel to collect whey. Everything fits inside the fridge as one unit. No balancing bowls, no muslin cloth falling into the curd.
• DIY method — a fine muslin cloth or cheesecloth draped over a deep bowl. This works, but the cloth sags, the edges fall in, and it takes up awkward space in the fridge. It is the method everyone starts with and eventually gets frustrated by.

Step-by-Step: How to Make Greek Yogurt at Home

Step 1: Start with thick curd.

Use homemade curd set with full cream milk, or store-bought Amul / Mother Dairy full cream dahi. The curd should be well-set, firm to the touch, and not sour. If you are making curd from scratch, an automatic curd maker (Rs 1,199) maintains consistent temperature and gives you perfectly set curd every time — especially useful in summer when curd over-ferments quickly.

Step 2: Place the strainer inside the outer container.

If you are using the 1100ml yogurt maker, drop the 304-grade stainless steel mesh strainer into the outer container. If you are using the 2500ml model, place the nylon mesh strainer basket inside and keep the spring-loaded pressure plate aside for now. The strainer should sit above the base of the outer container — that gap is where the whey collects.

Step 3: Add curd to the strainer.

Spoon or pour the curd gently into the strainer. Do not stir it. Do not press it down. Do not try to speed up the process. Disturbing the curd structure at this point breaks the protein matrix and makes it harder for the whey to separate cleanly. Let gravity do the work.

Step 4: Cover with the lid.

Place the silicone-sealed lid on top. This prevents the curd from absorbing fridge odours (onion, garlic, leftover curry — the usual suspects). If you are using the muslin cloth method, cover the bowl tightly with cling wrap.

Step 5: Refrigerate for 3–4 hours.

This is the sweet spot for Greek yogurt consistency — thick, creamy, and scoopable, but still smooth and spreadable. The curd loses roughly half its volume as whey drains into the outer container. Set a timer or plan around a meal — start after lunch, and it is ready by evening.

Step 6: For thicker hung curd or labneh, strain 6–8 hours or overnight.

If you want the ultra-thick consistency used for shrikhand, hung curd dips, or Middle Eastern labneh, leave it in the fridge for 6–8 hours. Overnight straining (10–12 hours) gives you a cream cheese-like texture that you can roll into balls. The longer you strain, the thicker and tangier the result.

Step 7: Remove the strainer.

Lift the strainer out. What is sitting on top of the mesh is your thick, creamy Greek yogurt. What collected in the outer container below is whey — a clear, yellowish-green liquid packed with protein, probiotics, and minerals.

Step 8: Save the whey.

Do not pour it down the drain. Whey is genuinely useful:

• Chapatti dough — replace water with whey for softer rotis
• Smoothies — add to any fruit smoothie for a protein boost
• Soups and dals — use as the liquid base instead of water
• Fermented rice — soak leftover rice in whey overnight for a probiotic breakfast
• Plant watering — dilute 1:1 with water and use as a natural fertiliser

Whey keeps in the fridge for 5–7 days in a sealed container.

Straining Time Guide

Why always in the fridge: Room temperature straining is risky. At 25–35°C (typical Indian room temperature), bacteria multiply rapidly in dairy. The curd turns sour within 2–3 hours, and you get tangy, over-fermented yogurt instead of the mild, creamy kind. Fridge straining at 4°C slows bacterial activity, prevents souring, and gives you a smoother, milder Greek yogurt. There is zero reason to strain at room temperature.

1100ml vs 2.5L — Which Size?

The honest recommendation: If you eat Greek yogurt daily and live with 1–2 other people, the 1100ml is the right size. It is compact, uses a stainless steel mesh (easier to clean, more durable), and fits neatly in the fridge. If you have a family of 4+ or you make shrikhand, hung curd dips, or large batches for the week, the 2.5L is worth the extra Rs 500 — the pressure plate also lets you speed up the straining when you are short on time.

Common Mistakes and How to Avoid Them

Mistake 1: Pressing or stirring the curd in the strainer.

It is tempting to push the curd down to speed things up. Do not. Pressing breaks the protein matrix and forces fine curd particles through the mesh along with the whey. The result is grainy Greek yogurt on top and cloudy whey below. Let gravity work. If you are using the 2.5L model, the spring pressure plate applies gentle, even pressure without breaking the curd structure — that is what it is designed for. Your hand pressing down with a spoon is not even pressure.

Mistake 2: Starting with watery or sour curd.

If the curd was not set properly — if it is runny, has visible water pooling, or tastes sour — no amount of straining will save it. Greek yogurt is only as good as the curd you start with. Use full cream milk (minimum 3.5% fat). Make sure the curd is thick and well-set before straining. If your curd comes out watery, the problem is in the curd-making stage, not the straining stage. This is where an automatic curd maker helps — it maintains the exact temperature range (40–45°C) for 6–8 hours, producing consistently thick curd regardless of season.

Mistake 3: Straining at room temperature.

Some older recipes suggest straining curd at room temperature "for faster results." This is bad advice in Indian conditions. At 30°C+, the lactobacilli in curd continue fermenting aggressively, producing lactic acid. Your Greek yogurt turns sour and tangy within 2–3 hours. Fridge straining at 4°C slows fermentation to a crawl, giving you mild, creamy yogurt with a clean taste. Slower straining also produces a smoother, more uniform texture.

Mistake 4: Using low-fat or toned milk curd.

Fat is what gives Greek yogurt its signature creamy, rich texture. Low-fat curd produces Greek yogurt that tastes chalky and thin — the same reason low-fat store-bought Greek yogurt needs stabilisers and thickeners to feel "creamy." Use full cream milk (Amul Gold, Mother Dairy full cream) for the curd. The difference is dramatic.

Mistake 5: Not covering the container.

Uncovered curd in the fridge absorbs every odour around it. Your Greek yogurt ends up tasting faintly of last night's curry. Always use a lid. The yogurt maker's silicone-sealed lid handles this. If you are using the muslin cloth method, stretch cling wrap tightly over the bowl.
