Cryogenic Grinding – Unlocking the True Taste of Spices

Ever wondered why freshly ground spices at home smell so much stronger than the powders you often buy? The answer lies in the grinding process. Traditional grinding methods use high-speed machines that generate heat — which is the enemy of spices as it evaporates delicate essential oils, dulls natural colours, and leaves behind flavour that feels flat.

That’s where cryogenic grinding changes the game. Instead of grinding at normal room temperature, spices are cooled to ultra-low temperatures, up to –170 °C, using liquid nitrogen before they are processed. At this point, the spice becomes brittle, and instead of losing its essence to heat, it breaks cleanly. The result? A powder that retains its original oils, vibrant colour, and authentic aroma.

This method doesn’t just make spices smell and taste better — it also makes them cleaner and longer lasting. The freezing step reduces microbial load and prevents clumping, ensuring every pinch you use is as fresh and pure as nature intended.

By combining the wisdom of traditional farming with this cutting-edge process, we’re able to deliver spices that are purer, more aromatic, and closer to their natural state.

What Is Cryogenic Grinding?

Cryogenic grinding, also called cryo-milling or freezer milling, is a modern grinding method where raw material is chilled with liquid nitrogen to around –170 °C before being ground. At this temperature, the spice becomes brittle and shatters cleanly instead of deforming. This prevents the loss of flavour and aroma compounds that normally escape in traditional grinding.

Key Benefits for Spices

Authentic Aroma & Taste

Essential oils stay intact, so your spices remain rich, aromatic, and full of natural flavour.

Vibrant Colour

No heat damage means the natural colour of turmeric, chilli, or coriander stays fresh and bright.

Cleaner & Safer

Ultra-low temperatures lower microbial load, making spices more hygienic.

No Clumping, Longer Freshness

The powder remains free-flowing and potent for a longer shelf life.

The Future of Flavour

Cryogenic grinding is more than just a new technique — it’s a revolution in how food and ingredients are processed. By protecting what nature puts into spices, this technology ensures that what reaches your kitchen is purer, fresher, and more powerful in taste.

That’s why when we say “Cold is Bold”, we mean it!
