One of the oldest preservation methods known is the process of fermentation. Fermentation is when tiny microorganisms break down sugars and starches. This is done to preserve food, change texture, or to create new flavors.There are many fermented foods that are eaten all over the world on a daily basis including kimchi, sauerkraut, yogurt, sourdough, as well as drinks including beer, wine, and kombucha!
Evidence of fermentation has been found as far back as 7000 BC. The incorporation of fermentation in food preparation has been beneficial for multiple reasons including, longer storage, better taste, easier digestion, and safer consumption.
Archeological evidence of fermentation is abundant across the globe with some of the earliest evidence indicating that beer brewing was occurring 13,000 years ago! Historical archeologists also recover evidence of fermentation practices at Euroamerican settlement sites in North America by recovering sauerkraut crocks! You may find a similar one in your kitchen!
