When we launched Terra Lava in the fall of 2025, one of our non-negotiables was purity.
Not in the marketing sense, but in the literal, measurable, lab-verified sense.
Coffee is among the more heavily treated crops in industrial agriculture, and it also happens to be notorious for mold growth during harvesting, processing, transport and storage.
What many people don’t realize is how wide the gap is between coffees that claim to be clean and coffees that are actually tested and shown to be free of mold and mycotoxins.
So here’s the simple truth: every batch of Terra Lava coffee is third-party lab tested, and the lab reports we’ve received show zero detectable mold, yeast, glyphosate, heavy metals or mycotoxins – including Ochratoxin A and all major aflatoxins.
And that’s only the beginning.
We also screen for:
- Glyphosate
- Heavy metals
- Other agricultural contaminants that tend to show up in commercial beans
The reason we go to these lengths to ensure our coffee is truly mold and mycotoxin free is pretty straightforward: while sourcing from a regenerative, shade-grown Costa Rican farm dramatically lowers the risk of contamination, it does not eliminate it. So lab verification is the only way to guarantee a pure cup.
Our testing process is simple.
- First, we pull samples from each roasted batch.
- Second, we send those samples to an accredited third-party lab.
- Third, they test for mold spores, mycotoxins, pesticides and metals.
That’s how we know – based on actual evidence – that the coffee we ship to you is actually clean.
Why Mold in Coffee Is a Problem for Your Health
A small amount of mold exposure here or there probably won’t change your life.
The issue is that most people drink coffee every day, and often several times a day. Low-grade contamination adds up in a way that’s easy to overlook.
Two things matter most here: mold spores themselves, and the mycotoxins that certain molds produce.
People often report short-term symptoms like:
- Headaches
- Brain fog
- Irritability
- Fatigue or mid-day crashes
- Digestive issues
- A jittery feeling that has nothing to do with caffeine
These are all signs that your body is trying to process something it doesn’t like.
The long-term concerns are even more serious. Chronic exposure to mold or common mycotoxins like Ochratoxin A and aflatoxins has been associated with:
- Systemic inflammation (source)
- Immune dysregulation (source)
- Increased oxidative stress (source)
- Hormonal disruption (source)
- Reduced mitochondrial function and compromised energy production (source)
In other words, mycotoxins do not simply irritate your system; they interfere with how it works.
Since inflammation sits at the center of so many modern health issues, contaminated coffee can create a slow drip of stress on the body that people rarely trace back to their morning cup.
Does mold in coffee trigger inflammation?
For many people, it does.
Ochratoxin A, for example, is well known for promoting oxidative stress and inflammatory cascades.
Even if you don’t notice anything dramatic, that subtle “off” feeling after a cheap cup of coffee — a tight chest, buzzing nerves, anxious edge, digestive weirdness — often has more to do with contaminants than caffeine.
If you care about energy, digestion, sleep, hormones or training recovery, avoiding moldy coffee isn’t optional – it needs to be your baseline.
How Coffee Gets Contaminated In the First Place
Coffee can pick up mold at several stages of production, which is why origin and processing matter more than most people think.
1. Harvesting
Low-quality coffee is often strip-picked, which means ripe and unripe cherries are pulled together. Unripe or damaged cherries hold more moisture and microbes, which makes them prime real estate for mold.
2. Processing and Drying
This is where things go wrong most often.
Coffee needs to reach a stable moisture level – usually around 10–12% – before it can be safely stored. If the drying process is rushed or uneven, or if the weather is too humid, mold can easily develop on green coffee.
The processing method matters, too.
- Washed coffees rely on careful fermentation and water management.
- Honey-processed coffees keep some fruit on the bean, which can be risky for mold when processed poorly.
- Natural coffee (also known as dry-processed coffee) is even more sensitive to airflow and humidity.
3. Storage and Shipping
Once the coffee beans are dried, they still need to survive storage and transport.
Heat, humidity swings and poor ventilation all encourage mold growth.
Most low-cost coffees spend a long time in these conditions, increasing their risk for contamination.
4. Roasting and Packaging
Roasting reduces some mold and mycotoxins, but does not fix contaminated beans.
Packaging also matters; if roasted beans are exposed to humidity or oxygen, the door is open for more contamination.
How We Keep Terra Lava Mold-Free, From Farm to Bag
This is the part that gets me excited, because it shows how much intention goes into every step of our production process.
Terra Lava isn’t clean by accident. It’s clean because we designed it that way.
Regenerative, Shade-Grown Farming in Volcanic Soil
Our partners in Turrialba, Costa Rica, grow coffee without pesticides or chemical fertilizers. The volcanic soil is rich in minerals and supports resilient plants, lowering disease pressure and reducing the need for chemical inputs.
Selective, By-Hand Harvesting
Only ripe cherries make the cut, and we pick them by hand rather than machine.
That eliminates a huge portion of the mold risk, since underripe and damaged cherries bring moisture and microbes into the mix.
Honey Processing Done With Precision
Honey processing can be risky or incredible, and the difference comes down to technique.
At Terra Lava we rely on:
- Clean, controlled fermentation
- Raised-bed sun drying
- Regular turning for airflow
This prevents moisture pockets and produces a sweeter, more aromatic bean.
Layered Sorting and Density Grading
Multiple rounds of sorting remove defective cherries before drying, which means fewer problem beans ever enter the system.
Low-Temperature, Small-Batch Roasting
Roasting reduces some microbial load, but our focus is on preserving natural sugars and aromatics. So we roast in small batches to maintain control and consistency.
Freshness matters too, so we roast regularly rather than storing roasted beans for long periods.
Optimal Storage and Moisture Control
Before roasting, the beans are dried to a safe moisture level and stored in breathable bags. After roasting, we seal them in compostable, plastic-free, high-barrier bags that keep out humidity and oxygen.
Third-Party Lab Testing
This is our final guardrail.
We test every batch for:
- Mold and mold spores
- Ochratoxin A
- Aflatoxins
- Glyphosate
- Heavy metals
- Additional agricultural residues
Only clean batches make it out the door.
Coffee Should Support Your Health, Not Undermine It
Many people clean up their diet, focus on sleep, train hard, and work on stress management, yet still drink whatever coffee is on sale at the grocery store. They never connect their sluggish mornings or afternoon crashes to contamination.
Your morning cup should lift you up. It should not create inflammation, brain fog, or hidden stress on the body.
That’s the philosophy behind Terra Lava. Coffee that supports your health. Coffee that is clean, tested, and grown with respect for the land and the people who cultivate it.
If you’re intentional about what you eat and drink, you deserve a cup that elevates you, not one that drags you down.
