Tuscan Tradition. The Art of Taste.
Chef Mario Gaeta draws on the great Tuscan culinary tradition, interpreted with care and a contemporary sensibility. Each dish is rooted in the land around us: organic vegetables, meats from local farms, aged cheeses from artisanal dairies, olive oil from the surrounding hills, and bread baked by hand each morning.
The menu changes with the seasons, because good cooking begins in the fields, not the kitchen. Every course is the result of a constant dialogue with the local terroir, capturing the food of Tuscany in its most authentic form.
Osteria LeCastelline welcomes estate guests and outside visitors alike, whether you dine beneath the exposed beams of our pietra serena stone dining room or on the pergola terrace as evening falls over the valley. Every meal here is a moment to cherish.

Executive chef: Mario Gaeta
Born in Naples in 1980 and a graduate of the Naples Hotel Institute, Mario moved immediately into elite gastronomy. He mastered his craft in the kitchens of six Michelin-starred restaurants across Rome and abroad, developing a technical expertise that spans from pastry to contemporary culinary techniques.
As an Executive Chef, he has led large kitchen teams and managed the complex logistics of restaurant openings. He specializes in building structured gastronomic projects that are as operationally sound as they are creative.
Mario’s approach and the Tenuta d’Arbia philosophy are perfectly aligned: both center on an uncompromising selection of ingredients. We source the highest quality local meat and vegetables, working directly with producers who share our commitment to the land. It’s a sustainable, seasonal kitchen where the provenance of every product is certain.
By balancing innovation with deep-rooted tradition, our chef transforms simple elements into a refined experience. His cooking is physical and grounded, honoring the seasons through precise, high-impact flavors. Quite simply, you’ll love it.

We welcome outside guests for dinner by reservation. Our kitchen serves a focused selection of tasting menus, built around the finest ingredients our valley and neighbouring producers bring to us each day.
Tasting menus are served to the whole table, allowing us to bring each course to all guests together. Dietary requirements and allergies are always happily accommodated, so please let us know when booking.

Sample Traditional Menu
This is the food you come to Italy for. What we cook changes with what’s growing, what’s ready and what the season offers from our nearby farms and producers. Some dishes come and go. Others return when the time is right. It’s straightforward Tuscan cooking, made with care and served with pride – and warm homemade bread & local olive oil.

Lunch & Dinner
The Breakfast Table
We lay out organic fruit, local honey, creamy yogurt from nearby farms, fresh bread, cakes and pastries still warm from the oven, and the rest is up to you. Order from the menu, ask the chef for exactly what you feel like that day, and take your coffee just the way you like it.
Mornings take their time here. If you’re not already out walking the hills, the day starts very gently.
