Coors Light
Summary
Coors Light scores 1/100. Independent third-party testing detected 31.1 ppb glyphosate — the highest reading among the seven mass-market beers tested, likely from glyphosate-desiccated conventional barley malt. Beyond the glyphosate, the product is built on ethanol (a WHO IARC Group 1 carcinogen), corn syrup adjunct, and CO2 hop extract instead of whole hops. There is no safe level of alcohol per the WHO (2023). Owned by Molson Coors Beverage Company.

Contaminants 1
Source: Independent third-party laboratory testing
Glyphosate 31.1 ppb Moderate
A moderate level of glyphosate — elevated enough to be a real sourcing concern; cleaner-tested options exist.
Independent third-party testing detected glyphosate at 31.1 parts per billion.
Key ingredients 6
Ethanol (Alcohol)Very Bad
Classified by WHO's IARC as a Group 1 carcinogen — definitively known to cause cancer in humans. Even moderate alcohol consumption is causally linked to cancers of the breast, colon, esophagus, larynx, liver, and oropharynx. There is no safe level of alcohol consumption per the WHO (2023).

Brewing water; the dominant ingredient by volume.
See more about Water →Barley MaltNeutral
The primary glyphosate-residue vector in beer. Conventional barley in North America is commonly sprayed with glyphosate (Roundup) as a pre-harvest desiccant to dry the grain uniformly for combine harvesting; residues persist through malting, mashing, and fermentation.

Industrial fermentable adjunct (mostly dextrose). Fermented out into alcohol, but signals an ultra-processed brewing approach that lightens body and reduces cost rather than adding character.
See more about Corn Syrup →YeastNeutral
Saccharomyces strain used for fermentation; not a health concern.
See more about Yeast →Hop ExtractBad
CO2-extracted concentrated hop product replacing whole hops; ultra-processed adjunct used to standardize bitterness across mass production.
