St. Francis released its first Old Vine Zinfandel in 1990. The grapes were from a 75 year old vineyard in Sonoma County. Since that first release, St. Francis has added numerous small old vine vineyards to our Zinfandel family. All the vines are at least 50 years old and many are 80 to 100 years of age. All the vineyards are located in Sonoma County. Among these turn of the century Zinfandel vineyards are Petit Syrah and Alicante Bouchet vines which add to color and texture of the "field blend" wine. Due to the prodigious age of the vines, the different microclimates and dry farming, these parcels yield as little as one and not more than four tons per acre of exceptionally concentrated grapes. Harvest is timed so that when the grapes are picked, some of the clusters have become raisins, resulting in intensified varietal flavors.
The grapes are hand harvested and crushed into temperature controlled stainless steel tanks. Fermentation lasts 12 to 18 days. The different lots are then racked into new American oak barrels, for an aging period of 12 to 15 months. The wine is assembled without fining or filtration, bottled and held for four to eight months prior to release.
St. Francis Winery
For more than four decades, the wines of St. Francis Winery & Vineyards have reflected the finest mountain and valley vineyards in Sonoma County. Our founder, Joe Martin, fell in love with Sonoma Valley and established St. Francis Vineyard in 1971, planting 22 acres of Chardonnay and the first 60 acres of Merlot in Sonoma Valley. After achieving great success as a grower, Joe opened his own winery in 1979 with his business partner Lloyd Canton.
Today, a new generation of winemakers, Katie Madigan and Chris Louton, continues our long tradition of luscious, elegant, fruit-driven wines from Sonoma County grapes. We farm more than 400 acres of Certified Sustainable estate vineyards in Sonoma Valley and Russian River Valley, each with varying compositions of loam, clay and volcanic soils. We also nurture long-term relationships with top Sonoma County grape growers, giving the Winery access to some of the region's most coveted old vines Zinfandel and other varietals from acclaimed vineyards.

Twice as large as Napa in size, Sonoma County only makes about half as much wine as its northeasterly neighbor. Because of its vast size, however, Sonoma is able to achieve far more diversity within its borders, which include sub-AVAs that are climatically varied. The atmosphere of Sonoma is decidedly laid-back and down-to-earth, but the wines are serious and well-made, ranging in style from subtle and elegant to rich and powerful. Grape varieties are more varied here, from Pinot Noir and Zinfandel to Cabernet Sauvignon and Chardonnay.
The largest sub-AVAs of Sonoma include Dry Creek Valley, Russian River Valley, Alexander Valley and Sonoma Valley. Each sub-AVA, with its own micro-climate, is unique in its grape varieties and styles of wine. Dry Creek makes a mean Zinfandel while Russian River produces stand up Pinot Noir and Chardonnay. The Alexander Valley makes some of the better Cabernet Sauvignons in the county and Sonoma Valley creates excellent wines from all the above varieties. Other grapes found throughout Sonoma include Sauvignon Blanc, Merlot and Syrah.
It's not rare to see a wine's country of origin listed as "California." A country into itself in the wine world, California makes enough varieties and styles to match many European wine countries. It produces a diverse range of wines that span the quality spectrum.
The most famous of the California wine regions is Napa Valley, and these wines are certainly outstanding – but it's not as broad and diverse as its larger neighbor, Sonoma County. Down south, Santa Barbara's Santa Maria Valley is well-known for its Rhône blends, as well as cool-climate varieties like Pinot and Chardonnay. The Central Coast, the largest California AVA, has many different microclimates that lead to a wide range of wines with many sub-AVAs.
Most wine ranges from 10-16% alcohol by volume. Some varietals tend to have higher (for example Zinfandel and Cabernet Sauvignon) or lower alcohol levels (Pinot Noir and many white varietals), but there is always some variation from producer to producer. Some wine falls outside of this range, for instance Port weighs in closer to 20%, while Muscat and Riesling are usually a bit below 10%.
