Exploring Fermented Foods and Drinks Around the World.

Fermentation is one of the oldest culinary techniques known to humanity. Long before refrigeration, fermentation preserved food and added rich layers of flavor, texture, and nutrition. But beyond practicality, fermented foods and drinks have become cornerstones of many cuisines and cultures across the globe.

From the sour tang of Korean kimchi to the frothy charm of Ethiopian tej, fermentation speaks to a deep relationship between people, nature, and time. This global tour explores how different cultures use fermentation not just to preserve food, but to create something delicious, symbolic, and often full of health benefits.

What Is Fermentation?

Fermentation is a natural process where microorganisms like bacteria, yeast, and mold break down sugars and starches into alcohol or acids. These byproducts act as natural preservatives and often enhance the flavor and texture of food.

Types of fermentation include:

• Lactic acid fermentation (e.g., yogurt, sauerkraut)
• Alcoholic fermentation (e.g., wine, beer)
• Acetic acid fermentation (e.g., vinegar)
• Mold-based fermentation (e.g., miso, blue cheese)

Each process transforms food in unique ways and has given rise to some of the most iconic dishes and beverages in the world.

1. Korea: Kimchi and Beyond

Perhaps one of the most globally recognized fermented foods, kimchi is at the heart of Korean cuisine. This spicy, tangy mix of fermented vegetables—commonly napa cabbage and radish—includes garlic, chili powder, ginger, and fish sauce.

Traditionally made in large earthenware pots and buried underground, kimchi ferments over time and can be eaten fresh or aged. It accompanies nearly every Korean meal and offers a probiotic punch that supports gut health.

Other Korean fermented staples include:

• Doenjang: a fermented soybean paste used in stews and sauces.
• Gochujang: a sweet-spicy chili paste made with fermented soybeans and rice.
• Makgeolli: a milky, slightly sweet rice wine made through alcoholic fermentation.

2. Japan: Miso, Natto, and Sake

Japan’s fermentation culture is deeply intertwined with daily life and spirituality. Miso, a fermented paste of soybeans, rice, or barley, forms the base of miso soup and many other dishes. Depending on its age and ingredients, miso can range from light and sweet to dark and umami-rich.

Natto is another fermented soybean product, known for its strong smell, sticky texture, and unique taste. Often served over rice with soy sauce and mustard, natto is a breakfast staple praised for its high protein and vitamin K content.

And of course, there’s sake, Japan’s iconic rice wine, made through a double fermentation process using koji mold and yeast. It’s both a ceremonial drink and a gourmet pairing for Japanese cuisine.

3. Germany and Central Europe: Sauerkraut and Fermented Bread

Sauerkraut, fermented shredded cabbage, is a German classic often served with sausages and meats. Unlike pickled cabbage, sauerkraut relies on lactic acid bacteria for fermentation, which creates its signature tanginess and preserves the cabbage.

Germany and surrounding regions are also known for sourdough breads. Traditional rye or wheat sourdough relies on wild yeast and lactic acid bacteria for natural leavening, resulting in hearty, tangy loaves that keep longer than those made with commercial yeast.

Other notable fermented items include:

• Kvass (in Eastern Europe): a mildly alcoholic beverage made from fermented bread.
• Pickled vegetables: cucumbers, beets, and even mushrooms are often fermented in brine.

4. India: Dosas, Idlis, and Curd

Fermentation is deeply embedded in Indian food culture, especially in the south. Dosas (thin, crispy crepes) and idlis (soft steamed cakes) are made from a fermented batter of rice and urad dal (black lentils). The fermentation process gives these dishes a slight tang and improves digestibility.

Curd, or homemade yogurt, is another staple consumed daily across India. Often eaten with rice, used in marinades, or served plain with sugar, curd provides probiotics that support gut health.

India also has its share of fermented pickles and drinks:

• Kanji: a fermented carrot and mustard drink consumed in North India.
• Toddy: a naturally fermented palm wine popular in the south and coastal areas.

5. Ethiopia: Injera and Tej

Ethiopian cuisine is known for its communal and flavorful dishes, served atop injera—a spongy, sour flatbread made from teff, a native grain. The dough is naturally fermented for days, which gives injera its unique tang and airy texture.

Equally important is tej, a traditional honey wine fermented with a shrub called gesho. This homemade alcoholic beverage is often consumed during holidays, weddings, and religious ceremonies.

Fermentation in Ethiopian culture goes beyond food—it’s part of a larger social and spiritual practice.

6. Southeast Asia: Funk and Flavor

Southeast Asian countries boast some of the world’s most pungent and flavorful fermented foods.

In Thailand, nam pla (fish sauce) is a fundamental ingredient. Made by fermenting fish with salt, it adds depth and umami to nearly every dish.

Vietnam has its own version, nuoc mam, and also features mam tom, a fermented shrimp paste with a powerful aroma and taste.

In Indonesia, tempeh is a standout fermented product. Made from whole soybeans bound by mold fermentation, tempeh is firm, nutty, and packed with protein. It’s a popular meat alternative worldwide.

In the Philippines, bagoong (fermented fish or shrimp paste) is used as a seasoning or condiment with vegetables, rice, and meats.

7. China: Fermented Tofu and Black Beans

China’s fermentation heritage is vast and varied. Fermented tofu, often referred to as “stinky tofu,” has a strong aroma and creamy texture, making it a delicacy in some regions.

Doubanjiang, a fermented broad bean and chili paste, is essential to Sichuan cuisine, lending deep umami and heat to dishes.

Fermented black beans (douchi) are also widely used in Chinese cooking to add a salty, umami base to stir-fries and sauces.

Chinese rice wine and vinegar, both products of fermentation, are commonly used in marinades and cooking.

8. Scandinavia: Fermented Fish and Dairy

Scandinavian countries, with their long winters, have traditionally used fermentation to preserve seasonal bounty.

Surströmming (Swedish fermented herring) is infamous for its potent smell and acquired taste. It’s usually eaten outdoors with flatbread and onions.

Filmjölk in Sweden and skyr in Iceland are fermented dairy products similar to yogurt, often consumed at breakfast.

In Finland, viili is another fermented milk product with a unique stretchy consistency due to specific bacterial strains.

9. Latin America: Chicha and Fermented Corn

Fermentation in Latin America often revolves around maize (corn). Chicha, a traditional drink, is made by fermenting maize or other grains. In some cultures, it’s even chewed first to start the enzymatic process.

In Mexico, pulque—a fermented sap from the agave plant—is a milky, slightly sour beverage with a long pre-Hispanic history.

Curtido, a Salvadoran fermented cabbage slaw, is often served with pupusas and adds a tangy crunch.

10. Modern Fermentation Revival

With growing interest in gut health and natural foods, fermentation has seen a global revival. In cities around the world, artisan fermenters are creating kombucha, kefir, kimchi, sauerkraut, and miso with creative twists and local ingredients.

Chefs are incorporating fermented components to add complexity to their dishes, while home cooks experiment with sourdough, yogurt, and lacto-fermented pickles.

Fermented foods are now seen not only as traditional but also trendy—offering flavor and health in equal measure.

Health Benefits of Fermented Foods

Modern science is catching up to what traditional cultures have long known—fermented foods can be good for you. Some benefits include:

• Improved digestion: Fermentation breaks down complex molecules, making nutrients easier to absorb.
• Probiotics: Many fermented foods contain live cultures that support gut health and immune function.
• Enhanced flavor: The process adds depth, umami, and richness to food.
• Long shelf life: Naturally fermented foods are more stable and preservable without artificial additives.

Not all fermented foods contain live probiotics (e.g., those that are cooked), but even pasteurized versions offer great taste and nutrition.

Final Thoughts

Fermentation is more than a preservation method—it’s a cultural art form practiced for thousands of years. It connects us to our ancestors, our communities, and our microbiomes. From Japan’s miso to Ethiopia’s tej, fermented foods and drinks are deeply personal and profoundly global.

Next time you explore a new culture, consider tasting its fermented flavors. They are time-tested, nutrient-rich, and deeply expressive of place and tradition.
