Why We Use Ceramic in Our Pepper Mills

There’s a reason freshly cracked pepper smells so good.

Whole peppercorns hold on to their aromatic oils until they’re broken open. Turn a mill over a finished dish and those oils are released there and then, giving the pepper a warmth and fragrance that pre-ground pepper loses over time.

The grind makes a difference as well. Fine pepper settles quietly into soups, sauces and dressings. A coarse crack has more presence, adding texture and small bursts of flavour to eggs, salads, vegetables and grilled meat. A good mill should let you move easily between the two.

At the centre of every mill is the grinding mechanism. It’s the part doing the real work, and the material it’s made from matters.

Steel has long been used in pepper mills, and for good reason. A well-made steel mechanism is strong, sharp and very effective at grinding peppercorns. If a mill is only ever going to hold pepper, steel can do the job extremely well.

The drawback is that steel is less versatile. Salt and moisture can eventually cause corrosion—even stainless steel is corrosion-resistant, not entirely immune. This makes many steel mechanisms unsuitable for salt and means a steel pepper mill is best kept for that single purpose.

Ceramic behaves differently. It’s extremely hard, slow to wear and completely resistant to rust. It can handle pepper, salt, dried herbs and spices without the mechanism reacting with what passes through it.

Ceramic won’t magically add flavour to pepper. What it does is provide an even, reliable grind without contributing anything of its own. The flavour comes from the peppercorn; the ceramic simply lets it come through cleanly.

Its resistance to wear matters too. As a mechanism becomes worn, the grind can become uneven, producing too much powder alongside pieces that are still too large. Ceramic retains its grinding surface for a very long time, helping each turn remain consistent.

That consistency makes seasoning easier. You can grind finely when you want pepper to disappear into a dish, then open the mechanism for a coarser finish when you want the pepper to stand out.

Ceramic also makes sense in a working kitchen, where mills are often used close to boiling pots and pans. Steam should still be avoided where possible—it can make salt and spices clump—but it won’t cause the ceramic components themselves to rust.

This combination of hardness, consistency and corrosion resistance is why we use a plastic-free ceramic mechanism in our Mill No.3 and Mill No.4.

Both use a 20mm funnelling cone to guide peppercorns into the grinding area and can be adjusted from fine to chunky. The same mechanism can be used for salt, pepper, dried herbs or spices, and the ceramic components are guaranteed for 25 years.

The Mill No.3 and Mill No.4 offer different proportions, but the thinking behind them is the same: make an everyday object simple, dependable and satisfying to use.

Good pepper doesn’t need much help. Keep it whole, crack it when you need it and let it speak for itself.
