[1][2][3] There have been independent retail bakeries in San Francisco continuously since the California Gold Rush of 1849, and many restaurants make their own bread.
However, the wholesale market (which distributes bread to restaurants and grocery stores) was marked by a slow decline from the early heyday, and the subsequent emergence of a new generation of artisan bakers.
Starting after World War II, a generation of decline and consolidation [4][14] saw Americans increasingly eating packaged, sliced loaves.
"[3] Much of the decline paralleled nationwide trends, both for bread and other foods, toward consolidation, lower-priced and frozen ingredients, reduced labor costs and added preservatives for longer shelf life.
sourdough, they turned to the Microbiology Department at Oregon State University where a team led by Dr. William Sandine was finally successful in isolating the bacteria from the wild yeast (Candida humilis) and discovered the theretofore-unknown lactobacillus that produces the lactic acid that gives the bread its unique flavor.
In 1993 the San Francisco French Bread Company was sold to Illinois-based Specialty Foods Corp.[23] The sale marked the end of local ownership for three sourdough bakeries which had been in operation since the 1800s.
A popular sour dough bread was widely available from Pioneer Baking in the Los Angeles area, but it disappeared from shelves around the year 2000.
Among the hallmarks of the new artisan breads, loaves are exposed to steam while baking (a technique developed in Vienna, Austria), creating a shiny surface that may be crusty or chewy, while keeping the interior moist.
[31] Encouraged by advice from a winery in Bandol, they obtained Acme's starter culture from yeast of wine grapes they found at Sullivan's father's vineyard in Napa.
[34][35][36] In 1984, Eric and Carol Sartenaer, ex-Cheese Board Collective members, opened shop in a 450-square-foot “hole in the wall” bakery in Kensington, California.
[39] Many other artisan bakers have followed in the steps of Tassajara, Cheese Board, Narsai's, Acme, and Semifreddi's, often started by veterans of other local bakeries and of Chez Panisse.
In 1989 former Chez Panisse pastry chef Diane Dexter and her husband David started Metropolis Baking Company, hiring a head baker who had worked at both Acme and Semifreddi's.
[32] All told, in the early 2000s there were at least 65 "microbakeries" in the Bay Area,[2][15] including the original bakers (Boudin, Colombo, and Toscana), collectively making approximately 2.4 million loaves of bread per week.
Although they represent a return to older ideals of craftsmanship, modern San Francisco breadmakers do not generally try to recreate old-style bread.
[4] Because sourdough is even more sensitive to ambient weather than other bread, bakeries are heavily dependent on climate control, refrigeration, and meteorological measurements and predictions to maintain ideal temperature and humidity conditions, giving them a consistency that would have been impossible during the Gold Rush.
[2] Technically competitors, the various commercial bakeries keep cordial relations and openly share information, mirroring an international culture of collegiality among small bakers.
Large grocers such as Safeway, Whole Foods, and Andronicos have in-store bakeries that produce sourdough, baguettes, and rustic breads in their Bay Area locations.
Among these is a San-Francisco based chain, Il Fornaio, that licensed a breadmaking concept from Milan, Italy, and has spread internationally and distributes to supermarkets.
Restaurateur Pascal Rigo has opened a string of restaurants and patisseries under the umbrella "Bay Bread", which was purchased by Starbucks coffee to provide baked goods for its outlets.
[43] One trend is the resurgence and expansion of good sourdough bread companies that follow the model of the pre-Interstate Brands Parisian, Colombo, and Toscana.
They are of medium size, deliver to both artisan markets and large chains like Safeway or Nob Hill, and seek reasonable expansion.
