Il Fiorello Olive Oil Company

Il Fiorello Olive Oil Company has two olive groves; one is in Solano County’s Green Valley, and the other in Suisun Valley. Owners Ann and Mark Sievers settled here because the Mediterranean climate is just right for growing and producing their world-class olive oil.

Our name “Il Fiorello” means “little flower” in Italian. We chose it for the tiny, white flowers on the olive trees, each of which becomes a delicious olive for milling into our ultra premium oil.

Why we’re in Suisun Valley
Il Fiorello is a family-owned company dedicated to growing and milling the finest quality artisan olive oil. Owners Ann and Mark Sievers produce oil from their own certified organic groves. Their properties are located in Green Valley and Suisun Valley between Fairfield and Napa Valley, a still-rural area where creek-side soils allow good drainage for the trees.

Our Olive Varieties
In Green Valley, our grove is planted with a mixture of Italian varieties

  • Frantoio has robust flavor and slight but tangy, peppery taste.
  • Leccino has a bright olive flavor with a hint of butter, and it’s slightly richer tasting than the Frantoio.
  • Pendolino is a brilliant green olive that gives our blends a wonderful balance.

Our Suisun Valley grove is home to numerous international varieties.

Perfect Harvests
We use a state-of-the-art continuous system mill produced to our specification by Gruppo Pieralisi, the leading producer of olive milling equipment in the world. Our mill is the most modern and high technology milling machine in North America, one of only about 50 olive mills in the United States. There’s no greater joy than standing at the final separator, as the olives are milled, and seeing the fresh golden-green oil. The rich taste fills your mouth with delicious and complex flavors.
