25 Fermented Drinks: Examples, Benefits & How to Choose

What Are Fermented Drinks?

Fermented drinks are beverages produced through the controlled action of microorganisms — bacteria, yeast, or molds — that convert sugars and other compounds into acids, alcohol, or gases. This ancient preservation method transforms simple ingredients into complex, flavorful, and often probiotic-rich liquids. From the tangy fizz of kombucha to the creamy depth of kefir, fermented drinks span nearly every culinary tradition on Earth. In this guide, you will learn exactly what fermented drinks are, how they benefit your health, and how to choose from 25 distinct examples spanning dairy, grain, fruit, tea, and vegetable bases. Understanding fermented drinks matters because they offer a direct, food-based way to support your gut microbiome, a community of trillions of microorganisms that influence digestion, immunity, mood, and more.

Why Drink Fermented Beverages?

The Biological Background of Fermentation

Fermentation is a metabolic process in which microorganisms break down organic compounds, typically sugars, in the absence of oxygen. There are three primary types relevant to fermented drinks. Lactic acid fermentation, carried out by Lactobacillus and related bacteria, produces tangy flavors and is common in dairy ferments like kefir and lassi. Alcoholic fermentation, driven by Saccharomyces cerevisiae and other yeasts, yields ethanol and carbon dioxide, giving drinks like chicha and boza their gentle buzz. Acetic acid fermentation, performed by Acetobacter bacteria, converts alcohol into vinegar, as seen in apple cider vinegar and some kombuchas. Each pathway creates distinct flavor profiles, textures, and nutritional properties.

Health Relevance: What the Science Says

The health benefits of fermented drinks have attracted significant research attention. A 2023 review in Nutrients highlighted that regular consumption of fermented foods and beverages can improve gut microbiota diversity, enhance immune function, and reduce markers of inflammation. Many fermented drinks contain live probiotics — beneficial microorganisms that survive transit through the digestive tract and temporarily colonize the gut. These probiotics may help crowd out harmful bacteria, produce short-chain fatty acids that nourish intestinal cells, and modulate the immune system. However, it is important to note that pasteurized versions of fermented drinks often contain few or no live cultures, and individual responses vary widely.

Microbiome Involvement: How Fermented Drinks Interact with Your Gut

Your gut microbiome is a complex ecosystem of bacteria, fungi, viruses, and other microbes that live primarily in your large intestine. This ecosystem plays a central role in digesting fiber, synthesizing vitamins like B12 and K2, regulating metabolism, and communicating with your brain via the gut-brain axis. Fermented drinks can influence this ecosystem in several ways. The probiotics they contain can add beneficial strains directly to your gut. The organic acids produced during fermentation, such as lactic acid and acetic acid, can lower the pH of your intestinal environment, creating conditions that favor beneficial bacteria over harmful ones. Additionally, the fermentation process often breaks down antinutrients like phytic acid, making minerals more bioavailable. Still, the extent of these effects depends on your baseline microbiome composition, diet, and overall health status.

25 Examples of Fermented Drinks (Categorized by Base Ingredient)

Below is a comprehensive, categorized list of 25 fermented drinks from around the world. Each entry includes a brief description, cultural origin, and key characteristics. For quick reference, a summary table follows the list.

Dairy-Based Fermented Drinks

1. Kefir
Originating in the Caucasus Mountains, kefir is a fermented milk drink made by inoculating milk with kefir grains — a symbiotic culture of lactic acid bacteria, yeasts, and polysaccharides. It has a tangy, slightly effervescent flavor and a thinner consistency than yogurt. Kefir contains a remarkably diverse microbial community, often including 30-50 strains of bacteria and yeasts, making it one of the most potent probiotic drinks available. It is also naturally low in lactose, as the fermentation process breaks down most of the milk sugar.

2. Lassi
A traditional Indian yogurt-based drink, lassi is made by blending yogurt with water, salt, and spices (savory) or fruit and sugar (sweet). It is typically consumed fresh and not fermented after preparation, though the yogurt itself is a fermented product. Lassi is cooling and digestive, often served alongside spicy meals. It provides probiotics from the live yogurt cultures, primarily Lactobacillus bulgaricus and Streptococcus thermophilus.

3. Ayran
Popular in Turkey, the Middle East, and Central Asia, ayran is a savory yogurt drink made by mixing yogurt with cold water and salt. It is sometimes carbonated or blended with herbs like mint. Ayran is refreshing and hydrating, with a thin, frothy texture. Like lassi, its probiotic content depends on the use of live-culture yogurt.

4. Doogh
Similar to ayran, doogh is a carbonated yogurt drink common in Iran and Afghanistan. It is made by mixing yogurt with water, salt, and dried mint, then allowing it to carbonate naturally or adding carbonated water. Doogh has a tangy, salty, and slightly fizzy profile. It is often served as a digestive aid with grilled meats and rice dishes.

5. Kumis
Kumis, also spelled koumiss, is a fermented mare's milk drink originating from the nomadic cultures of Central Asia, particularly Mongolia and Kazakhstan. It has a sour, slightly alcoholic flavor, typically containing 2-3% alcohol. Kumis is made by fermenting mare's milk with lactic acid bacteria and yeasts. It is rich in B vitamins and has a thinner consistency than cow's milk kefir due to the lower casein content of mare's milk.

6. Cultured Buttermilk
Traditional buttermilk is the liquid left over after churning butter, but cultured buttermilk is made by fermenting low-fat milk with lactic acid bacteria, typically Lactococcus lactis. It has a tangy, slightly thick texture and is used in baking, dressings, and as a refreshing drink. Cultured buttermilk contains probiotics, though commercial versions are often pasteurized.

How to Make Fermented Drinks at Home (Simple Starter Guide)

Making fermented drinks at home is rewarding, cost-effective, and allows you to control ingredients and probiotic content. Below are the basic principles for beginners.

Essential Principles

• Sanitation: Clean all equipment, jars, and utensils with hot, soapy water or a no-rinse sanitizer. Contaminants can spoil the batch or introduce harmful bacteria.
• Start with a reliable culture: Use a purchased starter culture, kefir grains, a SCOBY, or a previous batch as your inoculant. Wild fermentation is possible but less predictable.
• Control temperature: Most fermentations thrive between 65-75°F (18-24°C). Yeasts prefer warmer temperatures, while lactic acid bacteria are more active at cooler ranges.
• Use the right vessel: Glass jars, ceramic crocks, or food-grade plastic containers are ideal. Avoid metal containers, as they can react with acidic ferments.
• Monitor for spoilage: Mold, off-putting odors, or sliminess indicate spoilage. When in doubt, discard the batch.

Simple Recipe: Tepache

Combine the peels of one pineapple, 1 cup of brown sugar, 1 cinnamon stick, and 4 cups of water in a clean glass jar. Cover with a cloth and secure with a rubber band. Let it ferment at room temperature for 2-3 days. When it becomes slightly fizzy and tangy, strain and refrigerate. Enjoy within 5 days.

Simple Recipe: Beet Kvass

Dice 2 medium beets and place them in a clean glass jar with 1 tablespoon of sea salt and 4 cups of water. Cover with a cloth and let it ferment at room temperature for 3-5 days. The liquid will become deep red and tangy. Strain and refrigerate.

Understanding the Connection Between Fermented Drinks and Your Gut Microbiome

The gut microbiome is a complex ecosystem of trillions of microorganisms that live primarily in your colon. These microbes break down dietary fiber, produce vitamins, regulate immune function, and communicate with your brain. The composition of your microbiome is influenced by your diet, environment, genetics, medications, and lifestyle. Fermented drinks can support this ecosystem by introducing beneficial bacteria and organic acids that create a favorable environment for microbial diversity. However, the effects are highly individualized. What works for one person may not work for another, and the same drink can have different impacts depending on your baseline microbiome composition.

Uncertainty and Variability: Why There Is No One-Size-Fits-All Answer

It is tempting to believe that a single fermented drink will solve digestive issues or boost immunity, but the reality is more nuanced. The probiotics in fermented drinks are typically transient — they pass through the digestive tract without permanently colonizing the gut. Their benefits depend on the specific strains present, the dose, the food matrix, and your unique gut environment. Additionally, many commercial products are pasteurized, which kills live cultures. Even among unpasteurized products, the microbial content can vary significantly between batches. Therefore, the best approach is to experiment with different fermented drinks, observe how your body responds, and choose those that you tolerate well and enjoy.

The Limitations of Guessing: Why Symptoms Alone Don't Tell the Full Story

Many people turn to fermented drinks because they experience digestive symptoms like bloating, gas, irregular bowel movements, or fatigue. While these symptoms can signal an imbalance in the gut microbiome, they are not specific enough to reveal the underlying cause. Bloating, for example, can result from small intestinal bacterial overgrowth (SIBO), dysbiosis, food intolerances, or even stress. Without objective data, it is difficult to know whether a particular fermented drink will help or worsen your symptoms. This is where understanding your gut microbiome at a deeper level becomes valuable.

What Microbiome Testing May Reveal About Your Gut Health

Microbiome testing analyzes the composition of bacteria, fungi, and other microbes in your gut using DNA sequencing technology. A comprehensive test can reveal which species are present, their relative abundance, and how they compare to reference populations. This information can help you understand whether your gut microbiome is diverse, whether you have an overgrowth of certain bacteria, and whether you lack key beneficial species. For someone interested in fermented drinks, microbiome testing can provide personalized guidance. For example, if your test reveals low levels of Lactobacillus or Bifidobacterium, you might prioritize dairy kefir or kombucha. If you have an overgrowth of yeast, you might choose fermented drinks that are lower in sugar and yeast content. Microbiome testing offers a window into your gut ecosystem that symptom tracking alone cannot provide.

Who May Benefit from Understanding Their Microbiome

Not everyone needs microbiome testing, but certain individuals may find it particularly valuable. Those with persistent digestive symptoms, autoimmune conditions, or metabolic issues may benefit from understanding their gut composition. People who have taken multiple courses of antibiotics, have a history of gastrointestinal infections, or are considering major dietary changes may also find testing useful. Additionally, individuals who have tried various fermented drinks without noticing improvement may discover that their gut microbiome has specific needs that a one-size-fits-all approach cannot address. A personalized gut health assessment can help you make informed decisions about which fermented drinks to include in your diet.
