It's in the research. And it's in the cup.
Researchers tested 155 drinks in 2025. Every single one had microplastics in it — hot coffee averaged 43 particles per liter. The bean isn't the problem. Everything it touches on the way to your cup is.
4.9 stars7 reasons people avoiding microplastics switch to Trevara (besides the taste)
Just found out there's plastic in your coffee? Here's why the fix is easier than you think.
02
Plastic packaging may be part of the problem
The same University of Birmingham study identified plastic packaging as a major source of particles in the beverages it tested. It did not test retail coffee bags, so it cannot tell us what a coffee bag adds. But if you want less plastic touching your coffee, the package is one easy place to start. Trevara comes in a metal can.
03
Know what is in your coffee
Every roasted batch goes to SGS, an independent lab, for screening for microplastics, mold, mycotoxins, and heavy metals. You get the result for the coffee you are actually drinking.
04
See the proof for yourself
Scan the QR code on your can and the full batch report opens on your phone. The actual measurement and detection limit are there whenever you want them.
Real lab, real results
0microplastic particles confirmed*
0/10mycotoxins detected*
0heavy metals detected*
<10CFU/g mold, below lab threshold*
*Batch №1, roasted bean, tested by SGS. Microplastics: no confirmed particles above 50 µm per 8 oz cup. "0" means below the lab's detection limit.
05
Keep your coffee fresher
Light and oxygen make coffee taste stale. The opaque, rigid, airtight can helps keep both out, so the last cup can taste closer to the first.
06
Drink coffee worth waking up for
Trevara is specialty grade, single origin coffee from Amazonas, Peru. Choose medium for cocoa and stone fruit or dark for a full, round cup with dark cocoa notes. Whole bean or ground.
07
Made by people who care what ends up in your cup
Founder Max Irvine built Trevara because he wanted great coffee with fewer plastic touchpoints and real proof behind the claims. That is why Trevara uses metal packaging, independently tests every roasted batch, and makes the report easy for you to read.
Cut the Plastic Out of Your Daily Coffee
Sealed in a metal can, never a plastic-lined bag — and screened for microplastics, mold, mycotoxins and heavy metals by an independent lab, every single batch.

Why Trevara?
Most coffee is packed in plastic, brewed through plastic and never tested. Trevara fixes the parts we can control: a metal can, an independent lab report on every batch, and coffee that's actually good.
What we test for — and what we don't claim
Microplastics, mold, mycotoxins and heavy metals — every batch, at SGS.
We don't call Trevara "microplastic-free." No lab can prove zero. We show you the number and the detection limit.
Origin & tasting notes
Amazonas, Peru · 1,000–1,800 m · fully washed, sun-dried · Typica, Caturra, Catuaí, Bourbon.
Medium: cocoa and stone fruit, gentle acidity. Dark: dark cocoa, low acidity, full body.

I have been buying my beans off trade and other subscription services for the past year. This has exceeded the flavor profile of any bag I’ve gotten from them. And a plus it comes in non plastic reusable packaging. Great beans.

Studies cited are independent research shared for context; they were not conducted on Trevara products, and Trevara does not claim its coffee produces any health outcome.
Lab results describe the tested batch of roasted coffee and are reported with the lab's detection limits; "0" and "non-detect" mean below the detection limit, not absolute absence.

Batch №1 · Tested by SGS
Four measures. Four passes.
Independent lab results on the roasted bean — what's in your can before your grinder or filter touches it.
| Microplastics | 0No confirmed particles above 50 µm, per 8 oz cup | Pass |
|---|---|---|
| Mold | <10 CFU/gBelow the lab's reporting threshold | Pass |
| Mycotoxins | Non-detectTen mycotoxins screened, none found | Pass |
| Heavy metals | Non-detectArsenic, cadmium, lead, mercury — all under 0.025 ppm | Pass |
"0" and "non-detect" mean below the lab's detection limit for that method. Every batch is tested the same way; a failed batch doesn't ship.
