Coffee should be something you look forward to - not something you worry about.
So it’s no surprise more people are searching for mycotoxin free coffee and wondering what it actually means.
Here’s the straight-talking version - what mycotoxins are, why they matter, and how Grumpy Mule’s stubborn standards already keep them firmly in check.
What are mycotoxins, then?
Mycotoxins are natural toxins produced by mould. They can sneak in if coffee cherries or beans are dried or stored in poor, damp conditions.
They’re not usually an immediate danger, but long-term exposure isn’t ideal - it can stress your system, irritate digestion or trigger sensitivities. Basically: not something you want swirling about in your morning mug.
Mould can grow even in decent storage, but the risk is very low. And we’ve got our own checks to keep it that way. Past tests at the Mule roastery have shown levels well below any critical limits.
How Grumpy Mule already reduces the risk
Good news is the Mule’s picky. With stubborn standards.
Sustainable sourcing
A lot of our beans come from high-altitude farms, where cooler, drier climates naturally lower the chance of mould. Better conditions = better coffee.
Careful roasting in Yorkshire
Every batch goes through strict checks, tests and tastings.
Organic options
Organic certification often comes with stronger standards on farming, processing and storage - an extra layer of reassurance.
Spot checks
Each year we run Ochratoxin A tests (a common mycotoxin) on 10 roasted samples across the range to keep an eye on things.
What to look for in any clean, high-quality coffee
If you’re checking a coffee’s clean bill of health, look for:
- Organic or Fairtrade certifications
- Clear origin and farmer relationships
- Proper drying and low-moisture storage
- Brands that test for mycotoxins or share their quality standards (hi 👋)

FAQ
Does all coffee contain mycotoxins?
Not all. Risk increases when beans are grown, dried or stored in poor conditions. Good sourcing keeps it low.
Is organic enough?
Organic helps - a lot - but proper drying, storage and testing matter too.
Does roasting remove mycotoxins?
High heat can reduce some, but not all. Prevention is the real key.
