Scoring methodology · Drinks

How we score drinks

Every drink is evaluated against 6 rules, worth a total of 115 points. Your score is the percentage of points the product earns on what we actually know about it.

Active version: 2026.06.05

Quality score

Earned out of possible

Each rule contributes points up to a known maximum. We sum them, divide by the total possible, and that's the headline number on the product.

Unknowns

No data earns no points

If we couldn't verify an attribute, that rule earns zero. Brands aren't rewarded for non-disclosure, and we don't fill the gap with a guess.

Clean ingredients

max · 52% of score

No harmful contaminants flagged. Severity- and amount-weighted against per-serving food guidelines (MADL) using the shared food-path penalty math.

Lab data indexed

lab_indexed

15
max · 13% of score

A full third-party lab report has been indexed for this product. Beverages in particular benefit from independent verification because contaminant leaching (PFAS, BPA, heavy metals) varies widely by packaging and supply chain.

Packaging

packaging

10
max · 9% of score

Container material. Glass jars and paperboard score at the top; PET / polystyrene / generic plastic at the bottom. Generic "container" / "bottle" with no material signal lands mid-tier.

Recognized certifications

5
max · 4% of score

Product carries at least one recognized third-party certification (USDA Organic, Non-GMO Project, Regenerative Organic, Fair Trade, etc.). Binary credit — verification of any one counts.

Added sugar

added_sugar

15
max · 13% of score

Per-serving added sugar with drink-realistic thresholds (most sodas are 30–40 g per serving). ≤2 g earns full 15 (unsweetened or very light); 2–8 g partial; 8–16 g reduced; 16–30 g minimal; >30 g zero. Falls back to "Total Sugars" when "Added Sugars" is undisclosed (less precise — naturally-occurring sugars count too).

Citation
AHA added-sugar limits (≤25 g/day women, ≤36 g/day men); FDA Daily Value (50 g).

Artificial sweeteners

artificial_sweeteners

10
max · 9% of score

Penalizes presence of aspartame, sucralose, acesulfame-K, saccharin, neotame, and advantame in the ingredient list. Each detected sweetener nibbles 4 points; first detected sweetener brings the rule down from 10 to 6. Allulose, stevia, and monk fruit are deliberately NOT on this list — they're natural-derived non-nutritive sweeteners with cleaner profiles. No ingredient list = unknown / partial credit.

Found something wrong?

Scoring is a function applied to evidence. If you think a rule fired on the wrong evidence, the per-product breakdown shows the source for every contribution — each one is challengeable. The methodology itself is version-controlled and evolves in public.
