Strained vs set: the fundamental split
Authentic Greek yoghurt is strained. After fermentation, whey is drained through cloth or centrifuge until the yoghurt reaches a thick, spoon-standing consistency. Set yoghurt, by contrast, ferments in the pot with no straining. It is common across northern Europe but is not the traditional Greek product.
The label "Greek yoghurt" is not currently protected in every export market; "Greek-style" is a common workaround for yoghurt produced outside Greece. If your programme depends on origin storytelling, contract only with Greek dairies and require the country of origin on the pack.
Cheesecloth strained vs mechanical centrifuge
How the whey is removed changes the yoghurt more than most buyers realise. Two industrial methods dominate: traditional cheesecloth (or filter-bag) straining and modern mechanical centrifuges. Both produce a legally "strained" yoghurt, but the finished product is measurably different in texture, mouthfeel, flavour and cost.
Cheesecloth straining hangs the fermented yoghurt in cloth sacks or bags in a cold room for 8 to 24 hours, letting gravity pull the whey out slowly. Nothing is agitated. The casein network stays intact, so the result is dense, layered and slightly waxy on the spoon, with the clean lactic tang of the ferment carried through.
Mechanical centrifuge (also called separator straining) spins the fermented yoghurt at high g-force to remove whey in minutes. Throughput is enormous and margins are stronger, but the mechanical shear breaks the casein gel; the yoghurt is then stabilised, homogenised and often reconstituted with cream or protein concentrate to rebuild body. Texture becomes smoother and glossier, flavour becomes flatter.
| Attribute | Cheesecloth / bag strained | Mechanical centrifuge |
|---|---|---|
| Process time | 8 to 24 hours, cold | Minutes, continuous |
| Casein gel | Preserved intact | Broken by shear, rebuilt |
| Texture | Dense, waxy, layered | Smooth, glossy, uniform |
| Flavour | Full lactic tang | Cleaner, flatter |
| Whey yield loss | 50 to 65% of input volume | Similar, but recovered as protein stream |
| Additives typical | None | Cream, milk protein, stabilisers common |
| Cost per kg finished | Higher | Meaningfully lower |
| Best fit | Premium, gourmet, authenticity-led retail | Mainstream retail, HoReCa, private label at scale |
Protein levels
Strained Greek yoghurt typically delivers 8 to 10 g of protein per 100 g at 2% and 5% fat levels, rising to 9 to 10 g per 100 g at 10% fat. This is roughly double the protein of standard set yoghurt and is the basis of the category's positioning in modern retail.
Retail formats
- 150 g and 170 g single-serve cups (retail, chilled).
- 500 g and 1 kg tubs for family retail.
- Flavoured 150 g cups (strawberry, blueberry, peach, honey, forest fruits).
- Cream-top and goat-milk lines as premium tier extensions.
Foodservice formats
- 5 kg and 10 kg catering pails for hotels, restaurants and central kitchens.
- Bulk food-grade bag-in-box for industrial and dessert manufacturers.
Private label
Greek yoghurt lends itself to private-label programmes because the underlying product is simple (milk, cream, cultures) and the market is used to shelf presence at multiple price points. Fat level, milk source (cow, goat, mixed), format and sleeve design are the four levers you actually control. MOQs for a cup-format cow's milk 5% strained yoghurt typically start around one truckload; goat and cream-top lines carry higher MOQs and shorter runs.
Packaging and shelf life
Cups are PP or PET with foil lids; tubs are PP with heat-sealed film and snap lids. Shelf life is typically 30 to 45 days from production at 4°C. Cold-chain integrity from Greece to your warehouse is the single most important operational variable.
MOQ considerations
One producer alone will quote roughly one full truck as an MOQ for a single SKU. theGreex often consolidates multiple SKUs from multiple producers to bring the effective entry point down to a mixed pallet or partial truck, which lets smaller retailers and challenger brands enter the category cleanly.
Buyer's checklist
Buyer FAQ
Questions we hear repeatedly from importers, distributors, retailers and HoReCa buyers.
Is "Greek yoghurt" legally protected?
The name is not a PDO. In the EU, courts have upheld that "Greek yoghurt" implies Greek origin, so non-Greek producers typically use "Greek-style". Outside the EU the position varies market by market.
What is the difference between cheesecloth strained and mechanical centrifuge yoghurt?
Cheesecloth strains slowly by gravity, preserves the casein network, and gives a dense, layered texture with full lactic flavour but at higher cost. Mechanical centrifuge strains in minutes by shear, then rebuilds body with cream or protein; texture is smoother and glossier, flavour flatter, and cost meaningfully lower.
How much protein is in authentic Greek strained yoghurt?
Typically 8 to 10 g per 100 g at 2% and 5% fat, and 9 to 10 g per 100 g at 10% fat, roughly double a standard set yoghurt.
What packaging works best for export?
PP or PET cups with foil lids for single-serve retail; PP tubs with heat-sealed film and snap lid for 500 g and 1 kg family formats; 5 to 10 kg catering pails for HoReCa. All under unbroken cold chain at 4°C.
How long is the shelf life?
30 to 45 days from production at 4°C for retail formats. Bulk food-grade formats are shorter.
What is the MOQ for a private-label programme?
One producer alone typically quotes about one truckload per SKU. theGreex often consolidates multi-SKU shipments so smaller brands can enter with a mixed pallet or partial truck.
Can I get goat or sheep milk Greek yoghurt?
Yes, from mountain-region dairies in Epirus, Thessaly and Central Greece. Volumes are smaller and MOQs and lead times are longer than cow's milk lines.
Are milk protein concentrate and stabilisers a red flag?
Not by themselves, but they change the product. If your positioning claims authenticity, contract only cheesecloth strained lines with no added protein or stabilisers, and confirm the technical spec in writing.
