Zellerbach hired Ralph Bradford Webb in 1956 to be his winemaker and Webb would be integral to the winemaking for the first two decades of Hanzell. Webb introduced four significant advances in enology that would subsequently be adopted by many other wineries, predicating consistency and quality for the entire industry -temperature-controlled fermentation, the use of French Oak barrels, the practice of "blanketing" young wines in tank with inert gas and the practice of induced malolactic fermentation.
The original 6 acre vineyard has grown to 42 acres today, allowing Hanzell to produce 6,000 cases annually: three-quarters Chardonnay and one-quarter Pinot Noir, retaining its identity as a very small winery dedicated to making the Burgundian varietals at the Grand Cru level. Through five decades, Hanzell has pursued empirical winemaking and established traditions on which great cellar-worthy winemaking is predicated. View all Hanzell Vineyards Wines
About Sonoma CountyView a map of Sonoma County wineries
Twice as large as Napa in size, Sonoma County only makes about a half the amount of wine as her northeasterly neighbor. But Sonoma, with her size, is able to vouch for more diversity within her borders, including sub-AVAs that are climatically varied. The atmosphere of Sonoma is decidedly laid back and down home country style. But in wines, they are keeping up with the Joneses, or Napa-ites if you will. Grape varieties are more varied here, from Pinot Noir and Zinfandel to Cabernet Sauvignon and Chardonnay.
Notable FactsThe 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.
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.
