During the early part of the century, Sonoma Valley dairy farmers transported their cans of milk via horse and wagon to the "Sonoma Mission Creamery" located on the corner of East Spain Street and First Street East, across from the historic Mission St. Francis Solano de Sonoma. This mirrors the marketing of Samuel Sebastiani who carted wine out to the stone quarry employees offering wine to them in masons in the quarry for 5 cents per ladle.

The Vella operation of today is actually a resurrection of a business which opened at the same location back on November 16, 1931. It was on that date that Thomas G. Vella and associate Celso Viviani opened their new business together as Sonoma Valley Creamery in a converted brewery, originally home to the Sonoma Ice and Brewing Company.

Sonoma Valley Cheese Factory came into being on November 16, 1931 with Thomas G. Vella and Celso Viviani opened the creamery in a converted brewery originally built to house Sonoma Ice and Brewing Company. The building is made entirely of stone, quarried from locations above the Sonoma Mountain Cemetery. "The Brewery" was operated by a corporation of local businessmen as the "Sonoma Ice and Brewing Company". This company successfully produced lager style beers and provided spirit to the entire Sonoma Valley. When Prohibition arrived and halted the production of beer, the company became a distributor for "Near Beer" and "Grape Juice", ice and near carbonated beverages. This change in marketing was not successful and the brewery closed.

When the building converted into a creamery, they produced primarily Italian types of cheese, including Dry and fresh Monterrey Jack. Both Thomas G. Vella and Celco Viviani worked in the creamery producing these types of cheese together.

When World War II in arrived 1941, Sonoma Mission Creamery closed its Sonoma Plant and the milk patrons were absorbed by Sonoma Valley Cheese Factory which continued to produce all types of cheese for the war effort. While this transition was occurring, Thomas G. Vella and Celso Viviani built a new plant at #2 Spain Street, where the Sonoma Cheese Factory is located today.
This site incorporated Fochetti's Blacksmith shop, which furnished the ironwork to the Sebastiani Winery.

Celso Viviani and Thomas G. Vella dissolved partnership in Sonoma, in 1948, and Thomas G. Vella continued sole production in Central Point Oregon. Pete Viviani joined his father as a partner in 1953 on the #2 Spain Street location and operated the Sonoma Cheese factory until 1969 when his son David and son in law Fred Harland joined Pete in a three-way partnership under the name Sonoma Cheese Factory. Over the years, Sonoma Cheese Factory has expanded production and added a retail store and deli to the operation.

In 1950, Thomas G. Vella returned to a Sonoma location to re-start production at the original Sonoma Mission Creamery, at the corner of East Spain Street and First Street East.

When the old Sonoma Ice and Brewing Company building site became available, Thomas G. Vella re-invented it as a cheese making facility. Between prohibition, the building had once been home to a mushroom growing company, used for dry storage and was damaged severely by a fire. Thomas G. Vella spent a considerable amount of time and efforts reconstructing the building to return its original dimensions. Today, Vella Cheese Company continues to produce many varieties of cheese that are available in each their on site retail store, local markets, and Sebastiani Winery as well as cheese and wine shops throughout the nation.
