Carl Griffith's sourdough starter, also known as the Oregon Trail Sourdough or Carl's starter, is a sourdough culture, a colony of wild yeast and bacteria cultivated in a mixture of flour and water for use as leavening. [1] Carl's starter has a long history, dating back at least to 1847, when it was carried along the Oregon Trail by settlers from Missouri to Oregon. It was then passed down as an heirloom within the family of Carl Griffith, who shared it via Usenet in the 1990s. [1] Since 2000, it has been maintained and shared by a dedicated historical preservation society; its volunteers keep the starter alive, feeding the organisms flour and water, and mail free samples worldwide on request for use by bakers in seeding their own cultures. [2]
As with any other sourdough starter, the yeasts in Carl's starter generate carbon dioxide by fermentation when added to bread dough, causing it to rise. [1] Bacteria of the genus Lactobacillus produce lactic acid, giving the bread a sour flavor. [2] Carl's starter is especially robust, quick-rising, and tolerant of mistreatment, [3] producing a consistent, reliable rise and good flavor. [1]
According to Carl T. Griffith, his family's sourdough culture was originally created by his great-grandmother, [2] who traveled with her sourdough west from Missouri along the Oregon Trail in 1847, [2] [4] settling near Salem, Oregon. [2] The sourdough starter was passed down to 10-year-old Carl Griffith in about 1930 in a Basque-American sheep camp. His family was building a homestead in the Steens Mountains at the time, and he baked bread in a Dutch oven in a campfire-heated pit. Griffith took his starter on cattle drives in southeastern Oregon, during which he baked in chuck wagons. [2] Griffith went on to be a lawyer, World War II veteran, and retired lieutenant colonel of the United States Air Force Reserve. [1]
The starter became publicly known in the 1990s through the early Internet via Griffith's presence on Usenet's rec.food.sourdough group. Though only marginally involved in conversations among the sourdough enthusiasts, he became known for his willingness to share his family's sourdough starter. [1] He mailed a few teaspoons of desiccated starter on request worldwide, asking for no money beyond postage, [4] to anyone who sent him a self-addressed stamped envelope. [5] The starter was accompanied by family recipes and instructions for reviving the dormant organisms. [4] Establishing a new starter can be difficult for new bakers, and Griffith's consistent, good-tasting sourdough became popular in the group. [1]
Griffith died in early 2000 at the age of 80. He had lived in Sequim, Washington, for the previous 10 years. [1] At the time, his reputation for sharing the starter had grown by word-of-mouth; he had been responding to about 100 requests per year. [1] As nobody in Griffith's family wished to continue growing his sourdough, the Usenet group assumed responsibility. Though none in the group had known Griffith well, Dick Adams created a website and asked for volunteers to help him. [1] Ten friends and devotees formed the 1847 Oregon Trail Sourdough Starter Preservation Society, also known as Carl's Friends, to maintain the starter and share samples without charge. [2]
Society volunteers grow the starter, dry it on trays into thin sheets, and grind the crumbly material into a coarse powder. At intervals of roughly a week, a volunteer mails small bags containing dried samples to requesters. [1] By 2003 they received up to 20 requests per week, and had representatives in Australia and the UK. [2] In 2019 the group included a chief starter grower, backup starter grower, keeper of the mailbox, and several culture keepers. In order to prevent cross-contamination, keepers of the culture are sworn to keep no other sourdough starter in their homes. [4]
Over the years requests have increased in number. The group received 2,169 requests in 2018, [1] and in 2019 the group received 30–90 requests per week. [4] The mailing volunteer notes that the website is regularly mentioned in newspapers publishing articles on sourdough bread, increasing demand. Sourdough has in general seen rising interest since the 1990s. [1] History is part of the appeal. "I like the throwback of traditional bread, the things our great grandmothers ate", writes professional baker Stacie Kearney. [6] Many individual starters, including Carl's, have been passed down through generations. [5] Sourdough baking requires minimal equipment and simple ingredients, but invites practice. [6] Purism is a part of the appeal. In the words of one online poster, "If you take flour, water, (wild) yeast and salt, and play around with time and temperature, what comes out of the oven is something utterly transformed." [2] Hobbyists often proudly share their work on social media. [7] [6]
Carl's Friends have distributed more than 54,000 samples of Griffith's sourdough starter. [6] During the 2020 COVID-19 pandemic, increased interest in home baking drove up to 300 requests per week. Supply availability was also a factor, as other leavenings must be bought in stores, while sourdough starter can be maintained and propagated with only flour and water. [6] Baker's yeast especially suffered supply shortages due to increased demand. [8] [9] One volunteer working with the society gave out over 800 active (wet) starter packets and mailed another 1,400 dry packets; her public offer resulted in people lining up outside her house. [6] [7]
Ecologists at the Robb Dunn Lab of North Carolina State University analyzed a sample of Carl Griffith's starter; it was one of 560 sourdough starters surveyed for microbial diversity in the Sourdough Project. They sequenced most of the starters for their unique communities of bacteria and yeasts. They found that Griffith's starter contains Saccharomyces cerevisiae , one of the most common yeasts among their 560 starters, consistent with Griffith's starter being the ancestor to many of the other starters. The bacterial content of Griffith's starter is mostly Lactobacillus brevis , with smaller amounts of eight other members of the genus. The lactic acid produced by these bacteria is less sour than the acetic acid produced by bacteria dominant in other starters. Griffith's starter also was found to have two non-pathogenic species of Streptococcus , a genus often associated with pneumonia. [1]
The stability of sourdough starters when moving between geographic locations remains an open question to bakers and microbiologists. Bakers anecdotally report that their starters change after they move or take it with them on vacation. It is possible therefore that the current starter is completely different from the original starter from Sequim, Washington, but the Society continues regardless. [1]
Bread is a staple food prepared from a dough of flour and water, usually by baking. Throughout recorded history and around the world, it has been an important part of many cultures' diet. It is one of the oldest human-made foods, having been of significance since the dawn of agriculture, and plays an essential role in both religious rituals and secular culture.
Amish friendship bread is a type of bread or cake made from a sourdough starter that is often shared in a manner similar to a chain letter. The starter is a substitute for baking yeast and can be used to make many kinds of yeast-based breads, shared with friends, or frozen for future use. The sweet, cake-like Amish cinnamon bread is a common bread that is made from this starter; it is a simple, stirred quick bread that includes a substantial amount of sugar and vegetable oil, with a mild cinnamon flavor. It has characteristics of both pound cake and coffee cake. The flavor of the finished product can be altered by cinnamon being omitted.
Sourdough or sourdough bread is a bread made by the fermentation of dough using wild lactobacillaceae and yeast. Lactic acid from fermentation imparts a sour taste and improves keeping qualities.
Baker's yeast is the common name for the strains of yeast commonly used in baking bread and other bakery products, serving as a leavening agent which causes the bread to rise by converting the fermentable sugars present in the dough into carbon dioxide and ethanol. Baker's yeast is of the species Saccharomyces cerevisiae, and is the same species as the kind commonly used in alcoholic fermentation, which is called brewer's yeast or the deactivated form nutritional yeast. Baker's yeast is also a single-cell microorganism found on and around the human body.
Rugbrød is a very common form of rye bread from Denmark. Rugbrød usually resembles a long brown extruded rectangle, no more than 12 cm high, and 30–35 cm wide, depending on the bread pan in which it is baked. The basic ingredient is rye flour which will produce a plain or "old-fashioned" bread of uniform, somewhat heavy structure, but the most popular versions today contain whole grains and often other seeds such as sunflower seeds, linseeds or pumpkin seeds. Most Danes eat rugbrød every day.
A bread making machine or breadmaker is a home appliance for baking bread. It consists of a bread pan, at the bottom of which are one or more built-in paddles, mounted in the center of a small special-purpose oven. The machine is usually controlled by a built-in computer using settings input via a control panel. Most bread machines have different cycles for different kinds of dough—including white bread, whole grain, European-style, and dough-only. Many also have a timer to allow the bread machine to function without operator input, and some high-end models allow the user to program a custom cycle.
Boudin Bakery is a bakery based in San Francisco, California, known for its sourdough bread. The bakery is recognized as the "oldest continually operating business in San Francisco." It was established in 1849 by Isidore Boudin, son of a family of master bakers from Burgundy, France, by blending the sourdough prevalent among miners in the Gold Rush with French techniques.
Biga is a type of pre-fermentation used in Italian baking. Many popular Italian breads, including ciabatta, are made using a biga. Using a biga adds complexity to the bread's flavor and is often used in breads that need a light, open texture with holes. Apart from adding to flavor and texture, a biga also helps to preserve bread by making it less perishable.
Rye bread is a type of bread made with various proportions of flour from rye grain. It can be light or dark in color, depending on the type of flour used and the addition of coloring agents, and is typically denser than bread made from wheat flour. Compared to white bread, it is higher in fiber, darker in color, and stronger in flavor. The world's largest exporter of rye bread is Poland.
A ferment is a fermentation starter used in indirect methods of bread making. It may also be called mother dough.
Pain de campagne, also called "French sourdough", is typically a large round loaf ("miche") made from either natural leavening or baker's yeast. Most traditional versions of this bread are made with a combination of white flour with whole wheat flour and/or rye flour, water, leavening and salt. For centuries, French villages had communal ovens where the townsfolk would bring their dough to be baked, and the loaves weighed from 1.5 to 5.5 kilograms (3–12 lb). Such large loaves would feed a family for days or weeks, until the next baking day.
In cooking, proofing is a step in the preparation of yeast bread and other baked goods in which the dough is allowed to rest and rise a final time before baking. During this rest period, yeast ferments the dough and produces gases, thereby leavening the dough.
Vienna bread is a type of bread that is produced from a process developed in Vienna, Austria, in the 19th century. The Vienna process used high milling of Hungarian grain, and cereal press-yeast for leavening.
Desem is both a type of sourdough starter made from whole wheat flour, spelt flour or other flours and water, and the resulting bread.
Salt-rising bread is a dense white bread that is traditional in the Appalachian Mountains, leavened by naturally occurring wild bacteria rather than by yeast. Salt-rising bread is made from wheat flour; a starter consisting of either water or milk and corn, potatoes or wheat; and minor ingredients such as salt and sugar.[1] Some common ways of eating salt-rising bread include a slice with sugared coffee poured over it, a grilled cheese sandwich, and the most popular preference, buttered toast.[1]
The sponge and dough method is a two-step bread making process: in the first step a sponge is made and allowed to ferment for a period of time, and in the second step the sponge is added to the final dough's ingredients, creating the total formula. In this usage, synonyms for sponge are yeast starter or yeast pre-ferment. In French baking the sponge and dough method is known as levain-levure. The method is reminiscent of the sourdough or levain methods; however, the sponge is made from all fresh ingredients prior to being used in the final dough.
The history of California bread as a prominent factor in the field of bread baking dates from the days of the California Gold Rush around 1849, encompassing the development of sourdough bread in San Francisco. It includes the rise of artisan bakeries in the 1980s, which strongly influenced what has been called the "Bread Revolution".
During the 2020 COVID-19 lockdowns, home baking experienced an explosion of interest, which was termed pandemic baking, lockdown baking, or quarantine baking. The increase in home baking sparked by the pandemic outlasted the lockdowns, resulting in an overall increase in interest in home baking.
