Coffee — heavy metals & overall contaminant load
Groundwork Ethiopia Heirloom Blend Organic Coffee
Light-roast organic Ethiopia coffee in CLP’s Clean 16, with a current exact product page and an origin story that fits CLP’s lower-average African-metals pattern.
VerdictStrong single-origin clean pick with a credible exact-product verification trail.
Why it ranks
Groundwork’s exact Ethiopia product is a good example of a Clean 16 coffee that also lines up with the broader patterns CLP disclosed. CLP said African-origin coffees had the lowest average heavy metals in the study, and this current Groundwork Ethiopia page is a clearly identified organic Ethiopian coffee in a bagged format. That does not prove this exact SKU won on heavy metals alone, but it makes it one of the easiest top-tier products to defend without leaning on generic stock imagery or fuzzy sourcing.
Highlights
- CLP Clean 16 — composite contaminant ranking
- Single-origin Ethiopia positioning on the live brand page
- Organic bagged coffee, a favorable format / transparency combination
- Exact live product image verified from the Groundwork page
- African-origin coffees averaged the lowest heavy metals in CLP’s published regional summary
Caveats
- CLP’s public data still does not publish a product-specific metals table for every coffee
- Light roast tends to carry more acrylamide than dark roast in general coffee chemistry discussions, even though CLP’s own summary emphasized dark and light beating medium
