Curd Strainer: 5 Types Compared for Greek Yogurt (SS vs Nylon)

Not all curd strainers produce the same Greek yogurt. The mesh fineness, material, and design of your strainer directly affect thickness, texture, and how much yogurt you actually get versus how much passes through or sticks to the strainer. This guide compares all five common types of curd strainers available in India so you can pick the right one for consistently thick, creamy Greek yogurt.

5 Types of Curd Strainers

1. Stainless Steel Mesh Strainer with Container

This is a purpose-built curd strainer: a fine SS mesh basket that sits inside a sealed outer container. You pour yogurt into the mesh basket, whey drains into the container below, and the lid seals everything for fridge storage. The InstaCuppa 1100ml (Rs 999) is this type.

Stainless steel mesh is the gold standard for yogurt straining. It is non-porous (zero odour absorption), non-reactive with acidic whey, easy to clean, and lasts for years without degradation. The mesh fineness is calibrated specifically for yogurt — fine enough to hold thick curd solids while letting thin, watery whey pass through.

2. Nylon Mesh Strainer with Pressure Plate

A larger-capacity strainer with a finer nylon mesh and an included pressure plate for pressing paneer or extra-thick yogurt. The InstaCuppa 2.5L (Rs 1,499) is this type. The nylon mesh is finer than stainless steel mesh, which means it catches even more solids and produces slightly thicker Greek yogurt.

The pressure plate is the key differentiator. You can place it on top of the yogurt and press down gently to speed up whey extraction, or use it to press paneer into a firm block. Without a pressure plate, you rely on gravity alone, which takes longer.

3. Muslin Cloth / Cheesecloth

The traditional option. Drape cloth over a colander, pour in the curd, gather the corners, and let gravity drain the whey. Works well for occasional use. The main issues — sticking, staining, odour, tearing — become problems only with regular use (weekly or more). If you strain once a month, cloth is a perfectly reasonable choice.

4. Nut Milk Bag

Originally designed for making almond milk or oat milk by squeezing blended nuts through a fine nylon bag. Some people repurpose these for yogurt straining. The mesh is very fine — excellent filtration. But the bag design is wrong for thick yogurt. You need to squeeze the bag to extract whey, which is messy with thick curd. The bag also does not sit neatly in a container, and there is no way to refrigerate it cleanly during long straining sessions.

Nut milk bags work for thin lassi or buttermilk straining but are frustrating for thick Greek yogurt. They are also difficult to clean after yogurt use — curd gets trapped in the seams and corners of the bag.

5. Fine Kitchen Sieve / Colander

The most common mistake people make: using a regular kitchen sieve or colander to strain yogurt. Standard kitchen sieves have mesh that is far too coarse for yogurt. The curd passes right through, and you end up with watery yogurt in the bowl and barely any solids in the sieve. Even "fine mesh" kitchen sieves are typically 0.5-1mm openings — yogurt needs sub-0.3mm mesh to strain properly.

If you already own a fine sieve and want to try, line it with a single layer of muslin cloth first. That combination works, but you are back to the cloth sticking and cleanup problems.

SS Mesh vs Nylon Mesh — InstaCuppa Models Compared

If you have decided on a dedicated curd strainer, the next question is which type of mesh. Here is how the two InstaCuppa models compare on the factors that actually matter for Greek yogurt.

Quick recommendation: If you primarily want Greek yogurt and hung curd for 1-2 people, the 1100ml SS mesh model (Rs 999) is the better value. The stainless steel mesh is more durable, easier to clean, and the compact size fits in most fridge doors. If you have a larger family, want to make paneer as well, or need bigger batch sizes, the 2.5L nylon mesh with pressure plate (Rs 1,499) is worth the extra Rs 500.

What to Look for in a Curd Strainer

Whether you buy an InstaCuppa strainer or another brand entirely, these are the four factors that determine whether your curd strainer will produce good Greek yogurt consistently.

1. Mesh fineness (most important). This is the single biggest factor. If the mesh is too coarse, yogurt solids pass through and you get watery results instead of thick Greek yogurt. Look for mesh specifically designed for yogurt or cheese making — not general-purpose kitchen sieves. Test: hold the mesh up to light. If you can see distinct individual holes easily, it is too coarse for yogurt.

2. Material (SS > nylon > cloth). Stainless steel mesh is the most hygienic and durable option. It does not absorb odour, does not stain, does not react with acidic whey, and cleans with a simple rinse. Nylon mesh is a close second — fine, food-safe, and durable, though it can develop light staining over months of use. Cloth is the least durable and least hygienic for repeated use.

3. Ease of cleaning. Yogurt residue hardens quickly. Any strainer you choose should be easy to rinse immediately after use. Smooth, non-porous surfaces clean fastest. Avoid strainers with complicated textures, deep grooves, or cloth components where residue can hide. If the strainer is dishwasher-safe, even better.

4. Fridge-friendliness. Greek yogurt needs 4-8 hours of straining, ideally refrigerated. A good curd strainer should be a sealed, compact unit that sits neatly in your fridge without dripping or taking up excessive space. If the strainer requires a separate bowl to catch whey and a plate to cover it, that is three items occupying premium fridge real estate. An all-in-one container with a lid is significantly more practical.

Our Verdict

For the best Greek yogurt at home, you need a strainer with fine mesh (sub-0.3mm), a non-absorbent material, and a sealed container for fridge storage. Here is our honest recommendation for each situation:

• Best overall for Greek yogurt: SS mesh strainer with container (like the InstaCuppa 1100ml, Rs 999). Fine mesh, non-porous, compact, sealed. Does one thing exceptionally well.
• Best for Greek yogurt + paneer: Nylon mesh strainer with pressure plate (like the InstaCuppa 2.5L, Rs 1,499). Larger capacity, finer mesh, pressure plate for versatility.
• Best on a budget: Muslin cloth over a colander (Rs 50-100). Works fine for occasional use. Replace the cloth every 2-3 months.
• Skip entirely: Nut milk bags for yogurt (wrong design), regular kitchen sieves (too coarse), and any strainer without a container for whey collection.

The difference between good and great Greek yogurt at home usually comes down to two things: the quality of your starting yogurt and the fineness of your strainer mesh. Use full-fat curd, strain for 6-8 hours, and use a fine-mesh strainer. That combination produces thick, creamy, store-quality Greek yogurt every time — regardless of which strainer brand you choose.
