The only coffee roaster to publish lab results for every single lot we produce.
The number on your bag unlocks the full testing history of that exact coffee.
Because we're fully vertically integrated, there are no middlemen, co-packers, contract roasters, or third-party logistics companies to contaminate our beans.

FAQs
At Heirloom, purity isn't a marketing gimmick. It's a promise that’s measured, verified, and validated in every roast. Most coffees on the shelf today, even those labeled USDA Organic, come with hidden risks like mold, toxins, pesticides like glyphosate.
These toxic intrusions find their way into poorly handled beans roasted at third-party mega roasting facilities that secretly roast many of the coffees in the market.
They’ve been linked to the chronic health epidemic, long-term health effects, and even cancer. But not at Heirloom.
Every single lot of Heirloom coffee undergoes rigorous third-party laboratory testing to ensure it’s clean and healthy.
No shortcuts. No residue. Just uncompromising clarity in your home and your cup.
We believe in radical transparency. Unlike anyone else in the coffee industry, we built a layer of insulation around our supply chain.
Since we control every aspect of the supply (like sourcing, buying direct from the farmers or Co-ops, importing, roasting, packaging, and distribution) we are able to control quality from beginning to end.
This includes three layers of lab-testing, which is unheard of in consumer packaged products.
This means we lab test the coffee:
- Once at the country of origin (unroasted) (before it ships)
- Once at the port of Oakland (unroasted) (before we receive it into our facility)
- Once (periodically) after we roast the coffee.
We partner with our third-party ISO accredited lab: Twin Arbor Labs (San Luis Obispo, California)
Although we take every possible step to fully insulate our supply chain against pesticides, heavy metals, synthetic fertilizers, and glyphosate, there are incidents where a gust of wind or a contaminated shipping container introduce nasty substances into our beans.
This is why triple testing is SO IMPORTANT.
If a coffee tests positive, we reject it. It will not enter our facility, it will not go into our roaster, and it will not end up in your bag.
But what about the farmer? We build long standing relationships with our farmer partners.
If the coffee tests positive and it's not their fault, we will reject the coffee and transfer it to the open green coffee market for another company to purchase.
The farmer will not be on the hook.
ND = Non Detectible
Pesticides: Zero Tolerance (ND)
Glyphosate: Zero Tolerance (ND)
Toxins: Zero Tolerance (ND)
Mold: Zero Tolerance (other than naturally occurring)
While trace microorganisms are naturally present in all agricultural products, our limit is extremely low. (10,000, CFU/g - an extremely low limit which is like a few drops of water dispersed in an ocean)
Heavy metals: Although every agricultural crop on Earth contains a microscopic level of heavy metals (thanks industrial revolution), our absolute highest limit is 100 parts per billion (per 100 grams of unroasted coffee) which equates to approx.
16 g × 0.000000125 g = 0.000002 g.
To put this into perspective, the amount of detectible heavy metal in a cup of Heirloom Coffee at our strict limit, is roughly one to two grains of sand spread across an entire stretch of coastline.
It's pretty freaking clean.
While there are no specific coffee industry standards in the U.S. for lab testing (Including the USDA or FDA), we base our benchmarks against global standards including Codex Alimentarius, European Standards, and the limited FDA/USDA standards (there are very few).
