In reality, there really is not any fixed definition for the term Boutique Winery. Most sales people claim that if a particular winery produces less than 2,000 cases of wine each year, then it is considered to be a boutique winery. By logical reasoning, any winery that produces less than 5,000 cases of wine per year will be regarded as a boutique winery. Most of the larger wineries produce a limited number of wine cases of a specific wine, which is then known as boutique wine. However, boutique wines can also be defined as a wine that is made in limited amounts, while expressing a certain amount of passion on the part of the winemaker.

In addition to the various well-known labels that have been crafting and producing different varieties of wines in Bay Area, you will find a whole host of boutique wineries that are treasured by the locals.

. Bouchaine Vineyards: The legendary Bouchaine winery is situated in the southern part of Napa valley, close to San Francisco. Bouchaine is a family-owned business, which is wholly devoted to crafting and making the delicious Chardonnay and Pinot Noir varieties. Bouchaine wines are a heady blend of nature as well as culture, a compelling expression of grape and craft that complements the sophistication of burgundy with the liveliness of California. Established on the site of one of the oldest operating wineries in Carneros, Bouchaine is located north of San Pablo and San Francisco. The fog that surrounds the region every night largely influences the climate in this winery, and the shallow clayey loam soils that are ideal for Chardonnay and Pinot Noir.
