Coffee Testing Standards
Independent testing. Clear results. No exaggerated promises.
At Peacemaker Coffee Company, transparency is part of our quality standard.
We use independent third-party laboratory testing on selected roasted coffee samples to help evaluate mold, yeast, and other quality factors when applicable. We publish representative reports so customers can see what was tested, when it was tested, and what the results mean.
Because coffee is an agricultural product, laboratory results can vary by crop, origin, roast, lot, storage conditions, sampling method, and testing date. A report represents the specific sample identified on that report, not every bag of coffee produced forever.
What We Test
Our currently published January 2026 laboratory reports cover selected samples representing:
-
Light roast coffee
-
Medium roast coffee
-
Decaf medium roast coffee
-
Dark roast coffee
The published reports evaluate:
-
Mold
-
Yeast
Each report identifies the sample description, lot number, testing method, completion date, laboratory reporting limit, and result.
When additional analytes are tested, the corresponding laboratory report identifies the substances tested, testing methods, and applicable reporting limits.
Why We Test Coffee
Coffee passes through farms, processing facilities, shipping containers, warehouses, roasting equipment, and packaging operations before it reaches the customer.
Testing provides an additional layer of quality verification that appearance, aroma, and taste alone cannot provide.
Our testing program is intended to:
-
Verify selected samples through an independent laboratory
-
Support responsible sourcing and handling standards
-
Identify potential mold or yeast concerns
-
Provide customers with greater transparency
-
Help us evaluate and improve our quality-control procedures
Laboratory testing is one part of our overall quality process. It works alongside careful sourcing, storage, roasting, packaging, and sanitation practices.
Who Performs the Testing?
Our published reports are issued through an independent third-party laboratory.
The January 2026 reports list:
-
FDA BAM Chapter 18 modified as the testing reference
-
ISO/IEC 17025:2017 accreditation
-
A2LA accreditation number 2918.04
Using an independent laboratory provides separation between the company selling the coffee and the organization performing the analysis.
Current Published Results
Our current published reports were completed on January 16, 2026.
The selected light, medium, decaf-medium, and dark roast samples each reported:
-
Mold: below 10 colony-forming units per gram
-
Yeast: below 10 colony-forming units per gram
These results are properly described as being below the laboratory’s stated reporting threshold for the samples tested.

How Often Is Peacemaker Coffee Tested?
Peacemaker commissions laboratory testing periodically on selected coffee samples as part of its quality-control program.
The date, lot number, sample description, test method, and result are shown on each published report. New reports will be added when updated testing is completed and approved for publication.
We do not change the date on an old report or present one sample result as though it represents every future crop or production lot.
How to Read a Coffee Laboratory Report
A laboratory report usually contains several important details.
Sample description
This identifies the coffee or roast category represented by the submitted sample.
Lot number
The lot number helps connect the result to a specific sample or production group.
Test method
The test method explains the procedure used by the laboratory to perform the analysis.
Reporting limit
A result shown as “less than” a stated number means the result was below the laboratory’s reporting or detection threshold.
For example:
Mold: less than 10 cfu/g
Yeast: less than 10 cfu/g
This does not necessarily mean an absolute zero is being claimed. It means the laboratory reported the result below the stated threshold using the identified testing method.
Test date
The completion date shows when the laboratory finished its analysis. More recent reports may better reflect current products, crops, or production practices.
What These Reports Confirm
The published reports confirm the results for the specific samples described in each document.
They provide evidence that:
-
Selected Peacemaker Coffee samples were independently analyzed
-
The laboratory used an identified testing method
-
The results were below the stated reporting threshold for mold and yeast
-
The reports include sample and lot information
-
The testing was completed by an accredited laboratory
What These Reports Do Not Prove
The reports do not establish that:
-
Every bag from every future lot will produce an identical result
-
Testing eliminates every possible contaminant
-
The coffee prevents, treats, or cures any medical condition
-
Every customer will experience the coffee in the same way
-
One tested sample represents the entire coffee industry
We believe transparent, sample-specific language is more accurate than making absolute claims.
Our Broader Quality Process
Third-party testing is only one part of the Peacemaker quality standard.
Our broader process includes:
-
Selecting specialty-grade coffee
-
Working with established coffee suppliers
-
Monitoring storage and handling conditions
-
Roasting and packing in Toledo, Ohio
-
Maintaining production and sanitation procedures
-
Using packaging designed to protect freshness
-
Reviewing laboratory findings when testing is completed
-
Publishing representative reports for customer review
Why We Use the Term “Mold-Tested”
Mold-tested means a selected coffee sample was submitted for laboratory analysis. The resulting report applies to that sample under the conditions and reporting limits stated by the laboratory.
This language provides customers with meaningful information without overstating what a single test can prove.
Frequently Asked Questions
Is Peacemaker Coffee mold-tested?
Yes. Selected Peacemaker Coffee samples are submitted for independent third-party laboratory testing. Current published reports are available on this page.
What does “below 10 cfu/g” mean?
It means the reported result was below the laboratory’s stated threshold of 10 colony-forming units per gram for the identified sample and test method.
Does one report cover every Peacemaker product?
No. Each report applies to the specific sample and lot described in that document.
Why can coffee-testing results vary?
Results can vary because of differences in origin, crop year, processing, storage, roast, lot, sampling method, and testing date.
Does laboratory testing guarantee health benefits?
No. Laboratory reports provide analytical information about the tested sample. They do not prove that a coffee product will prevent, treat, or cure a health condition.
Where is Peacemaker Coffee roasted?
Peacemaker Coffee is roasted and packed in Toledo, Ohio.
Transparency You Can Review
We believe customers should be able to see the evidence behind important quality statements.
