How we make our sauce – with love, mushrooms and damn good ingredients 🍄💥
Christian VetterShare
Actually, we just wanted to grow mushrooms.
But then we had… let’s say… a little fungal problem .
Our farm in Cologne (👉 pilzling.com ) was doing so well that we regularly harvested more than we could sell directly.
Throw it away? Didn't go in the bag.
And so our journey into the world of fermentation began – with one question:
How can we capture, preserve and refine all the flavor of our mushrooms?
🍜 The idea: mushrooms, but with soy sauce vibes
We were inspired by traditional soy sauce recipes – not to copy them, but to rethink them.
Instead of soy, we use noble mushrooms . Instead of industrial mass production, we offer:
👉 Handcraft, care and damn good ingredients .
Our goal? A sauce that isn't just salty—but deep, round, and exciting. A plant-based umami bomb. 🍄💥
🌾 The ingredients: quality, not compromise
We believe that taste begins at its source . That's why we pay attention to every detail—from the mushroom to the bottle:
✅ Organic substrate : Our mushrooms grow on regional, organic substrate – sustainable, nutritious, traceable.
✅ Hand-picked varieties : We cultivate only the best types – including oyster mushrooms, king oyster mushrooms & lion’s mane mushrooms.
✅ Organic grains from Europe : For fermentation we use koji rice or other grains from selected organic farms in the EU.
✅ Time & Care : Our sauce ferments slowly because taste requires patience.
✅ 100% handmade : From mushroom harvesting to bottling – everything happens right here in Cologne. No machine-made gimmicks, just real hands.
🔬 The magic of fermentation
For us, fermentation is not a trend, but an art form.
With the help of microorganisms, we transform our mushrooms into something completely new: a sauce with depth, umami, character.
It's a bit like magic – only with more hygiene regulations.
🤲 Why do we do it this way?
Because we don't like compromises.
Because we want to get the best out of our mushrooms.
Because every product you try from Shroom Boom is a piece of our belief:
👉 Good taste starts with good decisions.
🎯 Conclusion: It's more than just a sauce
Shroom Boom is not just a dip.
It is a product of surplus harvest, converted into liquid gold.
A sign of what happens when you bring quality, sustainability and curiosity together.
Too many mushrooms turned into a damn good idea. 🍄💥
