Red Rock Terrace, a warm microclimate, is eight acres of north facing vineyard. The red tinted soil is high in iron content. The wine from Red Rock Terrace is the most accessible and earliest drinkable of all our wines.
Our winemaker describes Red Rock Terrace as "having velvety tannins, rich and well balanced, medium dark ruby color with cherry, mint and black currant flavors."
Diamond Creek Winery
Diamond Creek, California's first "Cabernet only" estate vineyard, was established in 1968. Visionary pioneer, Al Brounstein, defied modern convention and planted Bordeaux varietals on secluded Diamond Mountain. The three distinct soil types on theis 20-acre property produce different single-vineyard Cabernet Sauvignons. Light ash soild of Volcanic Hill is in sharp contrast to the iron-rich Red Rock Terrace and the pebbly Gravelly Meadow. Each year, the estate produces a small amount of long-lived wines that are revered by connoisseurs the world over.

California has nearly 100 American Viticulture Areas (AVAs) and accounts for almost 90% of wine production in the United States. In our section of Other California, we include wines from smaller AVAs as well as wines from the California AVA. Here are a few smaller AVAs you may see on the label:
Livermore Valley AVA
, located right outside of San Francisco and home to wineries such as Wente.
Lodi County AVA
, an AVA further east of San Francisco and known for its excellent, old-vine Zinfandels.
San Francisco Bay AVA
, a sprawling AVA that covers Contra Costa, Santa Clara and Santa Cruz counties, to name a few.
Wine that holds only the California AVA is typically a wine that includes grapes from a number of different AVAs, which leads to the general labeling of the wine as California. This does not denote the quality of the wine, only the diversity of where the grapes originate.
It's not rare to see a wine's country of origin listed as "California." A country unto 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%.
