Originally, sourdough points to the cultures of various microbes
located in the San Francisco area. Later on, the term refers to miners
who brought sourdough starters everywhere they go. In recent
periods, the growth of huge-scale commercial baking, plus the
invention of different dough flavouring agents, led to sourdough referring to any type of sour bread, regardless of whether it is
leavened with natural leaven starter or using commercial baker's
yeast. The term may confuse a number of individuals, but knowing
the details and understanding how it is made can better improve your
technique.
The Differences
Sourdough starter is a culture of natural or wild yeast, together with
lactobacilli in a medium of liquid and flour. It is propagated using
ongoing feedings or refreshments with the sole purpose of leavening
bread dough. It is ongoing and continues from one activation or bake
to another. Sourdough bread has been leavened using a sourdough
starter. It may or may not be a sour bread, based on the
characteristics of the starter.
Sourdough is the term used to describe the natural leaven of natural
or wild yeast and lactobacilli. It is the process of leavening bread
using a natural leaven. The yeasted starter describes the starter that
has the commercial bakers' yeast.
Being Sour
Sour bread, also known as faux sourdough, describes any kind of
bread that has the sour flavor, because of a flavouring agent like
souring salts, ingredients like vinegar or yogurt or process that does
not include a natural leaven starter or a sourdough.
Sourdough bread does not have need to be sour bread. Sourdough
bread can be very sour, although it is also normal for it not to be
sour. It can be subtly flavored using delicious and rich wheaty
flavors. With sourdough, the level of sourness will depend on several factors like the kind of grains, temperature, length of fermentation,
specific yeast strains and lactobacilli and the amount of water.
About Hooch
As the starter is left in the refrigerator, the mixture will begin to
separate, leading to a layer of liquid forming at the top. The liquid
will have about 12 to 14 percent alcohol. Hooch is described as the
alcoholic by-product of the process of fermentation. This is will
feature a unique brownish color. The alcohol dissipates while
baking. You can stir the liquid back into the starter before you use it.
Hooch can build up in the starter, especially if you keep it in the
refrigerator. You can pour it or stir it back inside. You can mix the
hooch back in if the sourdough starter is on the dry area. Throw it
away if the starter is very moist.
Natural Leavens
Starters created using commercial bakers' yeast are not natural
leavens. These are actually yeasted starters that do not produce the
same results in terms of shelf-life, flavor and texture like natural
leaven starters. It is possible that a yeasted starter can be taken over
using natural yeasts and changing it into a natural leaven.
