Diadema was born from a vision: to turn the art of wine and olive oil into a truly unforgettable experience, blending tradition, beauty, and passion.

Every day, we breathe new life into a story that has its roots in Tuscany’s timeless heritage. Each glass of wine, each drop of oil, invites you to discover and share the magic of our land — where excellence meets authenticity, and every taste tells a story.

It all begins in Impruneta, the beating heart of Chianti, where the Giannotti family has nurtured a love for the land and its fruits for generations. Here, the Tuscan hills guard historic vineyards and olive groves, and the 19th-century underground aqueduct — the Galleria Filtrante — has been transformed into an enchanting aging cellar, giving our wines a truly unique soul.

The journey took shape with Alberto Giannotti, a visionary founder who combined deep respect for tradition with a drive for innovation. Today, together with his daughters Giulia and Livia, and Francesco, our Sales Director, the story continues with a fresh outlook — yet always rooted in the same core values: authenticity, creativity, and excellence.

Every Diadema bottle tells a story — a fragment of our identity:


Diadema Rosso, adorned with Swarovski crystals, the emblem of elegance and art.


Candegli, aged in terracotta amphorae, a tribute to our bond with Impruneta.


Villa L’Olmo, resting in the silence of the Galleria Filtrante.


Our extra virgin olive oils, still hand-harvested today, the guardians of ancient knowledge.


And our Champagne, completing the collection with an international spirit.

But Diadema is not only about wine and olive oil. It is family, hospitality, and emotion. At Relais Villa l’Olmo, we welcome travelers from all over the world to experience true authenticity: guided tastings, walks through our vineyards, visits to the olive mill, and to our underground cellar.
