One Simple change

Upgrading to a Biscotto stone can make all the difference.

Replace your thin, cordierite oven floor with an authentic Biscotto di Sorrento baking stone for a crisper crust, softer crumb, and a bigger, better cornicione. And stop burning the bottom of your pizzas.

The Perfect Clay

It all starts with Mt. Vesuvius

The geology of Sorrento, like much of the region surrounding the Bay of Naples, is known for its steep cliffs, hilly terrain, and volcanic activity. Sorrento’s soil contains volcanic ash and pumice, and is rich in silica, making its clay very porous. Using traditional production and refining methods, Sorrento clay becomes the perfect, natural material for making the world’s best pizza oven baking floors.

How a Biscotto stone works

Better Heat Retention

Biscotto’s high porosity allows it to heat up rapidly and hold its heat for sustained high temperature baking. Plus, our stones are up to twice the thickness of standard stones, giving you even more heat retention.

Slower Heat Transfer

The essential difference between Biscotto di Sorrento stone and a cordierite or firebrick floor is how the natural clay slowly and evenly releases its heat, giving you beautiful char—not burn.

Better High Temp Baking

The slower heat transfer combined with high porosity and a rough surface allow a Biscotto stone to absorb moisture in your dough and create the steam channels necessary for a light, crispy crust, without transferring heat too quickly.

Please. Do try this at home.


It’s all about the pizza

High temp baking, not burning

Evenly bake a pizza in 60-90 seconds (even 40 seconds!) on an 850-900ºF floor—without burning the bottom. With an ordinary cordierite floor, heat transfers too quickly and burns your carefully made pizzas.

Fast bake times

A Biscotto stone gives you the short bake times your pizza needs for the perfect balance of a crispy crust and a delicate, moist crumb. Longer bake times make your pizza drier and tougher.

Turns Moisture into steam

Biscotto is porous and it has a rough surface with channels that extracts moisture from your dough and quickly converts it to steam. Ask any baker, and they will tell you that steam is essential for making a great crust.

multiple pizzas in a row

No more one and done. You don’t want to wait for your cooking floor to re-charge between pizzas.  Biscotto stones are like a huge, efficient battery, storing heat and then evenly and slowly releasing it to your pizzas. That means you can bake multiple great pizzas in a row.

No expertise required

Biscotto stones aren’t just for expert pizzaiolos. In fact, they’re very forgiving, even for a beginner. Because you don’t need to worry about checking the bottom of your pizzas, your pizza making can be less stressful, and a lot more fun. Relax, get a Biscotto stone, grab a beer, and make some great pizza.

Perfect Cornicione

The hallmark of authenticity lies in the characteristic leopard spots—beautifully charred and slightly blistered patches that adorn the outer rim, signaling a wood-fired oven’s embrace. Each bite offers a delightful harmony of flavors, with the cornicione acting as a delicious prelude to the tender center.
