Stonyfield Organic Greek Nonfat Yogurt Plain - 32 oz: Full Nutrition, Labelgrade B+ (82/100)

The short answer

Stonyfield Organic Greek Nonfat Yogurt Plain delivers 16g of protein for 90 calories per 180g serving (USDA FDC 2757843) — and it does it with a single ingredient on the label: cultured pasteurized organic nonfat milk. It earns a B+ (82/100), with perfect marks on saturated fat, sodium, and sugar. This is the USDA-organic plain Greek yogurt in a 32 oz tub — the clean-label, buy-it-by-the-quart alternative to Fage and Chobani.

Why the B+

The honest read: the only thing keeping this out of the A range is protein density (C), and that’s a measuring quirk, not a flaw. The score is per 100g, where strained yogurt looks unimpressive because it’s largely water — but per serving the 16g is a legitimate “high in protein” portion. The fiber F is unavoidable for any dairy product. Everything Labelgrade actually penalizes for — added sugar, sodium, saturated fat, additives — this yogurt aces.

The organic is the whole point

Strip away the certification and this is a textbook plain nonfat Greek yogurt — which is exactly why the organic seal is the reason to reach for it over the cheaper twin. Look at the head-to-head: Chobani Plain Non-Fat posts the identical 16g protein and 90 calories per 180g, and scored an 81 to Stonyfield’s 82. The macros won’t decide it. What separates them is that Stonyfield’s milk comes from cows raised to USDA organic standards (no synthetic hormones, antibiotics, or non-organic feed), and its label lists one ingredient where Chobani spells out its six cultures. If organic dairy matters to you, this is the plain Greek yogurt that delivers it without compromising the nutrition.

What the single-ingredient label buys you

“Cultured pasteurized organic nonfat milk” is as short as a yogurt label gets, and the contrast across the shelf is real:

• Fage Total 5% adds cream (hence 160 calories and 6g saturated fat) plus five named cultures — richer, but a different macro profile entirely.
• Oikos Pro Vanilla chases a higher 20g protein, but does it with added whey protein concentrate, plus tapioca starch, stevia, and a preservative — a fourteen-item label engineered for protein, not a plain yogurt.
• Stonyfield does none of that. No gums to thicken it, no whey to spike the number, no sweetener. The 16g and the 5g of sugar are both just what’s left after the milk is cultured and strained.

That’s the trade you’re making: Stonyfield won’t win a protein-per-cup contest against a whey-fortified tub, but nothing on its label needs explaining.

How it compares

Read across: Stonyfield and Chobani are statistical twins on every macro, so the choice between them is organic vs. price. Fage trades 70 extra calories and 6g of saturated fat for a creamier full-fat texture. Oikos buys its 4 extra grams of protein with added whey and a longer ingredient list. Stonyfield’s lane is leanest-and-cleanest, certified organic.

The 32 oz tub is the value format

This is the quart tub, not a single-serve cup — roughly five 180g servings, about 80g of protein total. Buying the big tub is the cheapest way into organic Greek yogurt: you portion it yourself, skip the per-cup packaging markup, and use it where plain yogurt shines — as a sour-cream swap, a smoothie base, a marinade tenderizer, or a bowl you sweeten with your own fruit (keeping the added sugar at the zero the label starts with). The only shopper better served elsewhere is someone who specifically wants grab-and-go single cups or is chasing the absolute highest protein-per-serving, where a whey-fortified yogurt wins.
