How PureScore works (short)
PureScore is Label Matter’s 0–100 score for what’s on the label. Higher = cleaner / safer relative to Label Matter’s food ingredient model. Live weights on the methodology page: ingredient safety 40%, formulation quality 30%, contaminant risk 20%, label transparency 10% (+ coverage multiplier).
The oat ranking below is a catalog search for “oat milk” re-sorted by PureScore—same source as the live blog post. It is separate from the dairy alternatives Top 10 dump list (almond/coconut-heavy in the current snapshot).

Grocery-shopper takeaways
- Best clean-label pick in this snapshot: Oatly Organic Oat Milk (94, EXCELLENT).
- Solid mid-pack everyday cartons: Kirkland Signature and several plain Oatly SKUs around 74.
- Barista / fortified formulas (Califia Barista 69, Chobani barista 65, Oatly foamable 64) often score lower than the simplest organic carton—expected when the job is foam, not minimal ingredients.
- Flavored / mocha drinks are a different product. Dr. Bronner's mocha latte at 38 is not a plain oat milk substitute.
Head-to-head on the two cartons people ask about most: Oatly vs Califia by PureScore.

FAQ
Is this the same as the long oat blog post?
Same scores, shorter page. The full narrative and caveats live on /blog/cleanest-oat-milks-purescore. This page is the grocery-shopper ranking that points back there.
Will these scores change?
Yes. Formulations and catalog matches change. Re-check the live table or search oat milk on Label Matter before citing an old screenshot. Dump as_of is 2026-09-09 for Wave 1 Top 10 files; the oat ranking table shows updated September 5, 2026.
Is PureScore a nutrition score?
No. It is an ingredient-profile metric—not calories, macros, taste, foam, or sustainability.
