The Variety and Roles of Microbes

Students might not realize that many ordinary foods are made with microbes. Vinegar, for example, is soured wine.

Different vinegars obtain their flavors from the type of wine fermented (e.g., apple cider vinegar is made from apple cider wine, which is fermented apple cider) or from their surroundings after/during fermentation (e.g., balsamic vinegar is flavored by the balsamic fir wood barrels in which it is aged). 

Sauerkraut, soy sauce, coffee and chocolate also are produced with the help of microbes.

A recipe to make vinegar can be found at http://recipes.howstuffworks.com/how-vinegar-works2.htm.
