5 Popular Fermented Drinks (That Aren’t Wine from Grapes)

popular fermented drinks

The art of fermentation has been around for millennia. It’s a function of living microorganisms that are present all around us. Over time, humans have evolved with these bacteria and learned how to use them to create some of the world’s most popular fermented drinks. We would have never discovered alcohol without these living organisms. So, just how far back can we date alcohol production? Nine thousand years, to be precise. 

The earliest confirmed alcoholic beverage dates back to c. 7000-6600 BC in Jiahu in the Yellow River Valley of China (Henan province). People made a beverage from wild grapes, hawthorn, rice, and honey. The discovery was made by analyzing the residue inside ancient fermentation vessels. Porous clay pottery could absorb liquid, preserving the residue from environmental contamination for millennia. Through modern technology, chemical analyses prove the presence of alcohol in the residue. 

Studying fermented beverages can teach us about human civilization. It is the gateway to our history and learning about lost worlds. It can connect us to another time and place.

How Fermentation Works

Simply put, alcohol is the product of yeast breaking down sugars and converting them into molecules that produce ethanol and carbon dioxide. In nature, alcoholic fermentation is a natural occurrence. It happens in overripe or damaged fruit. The skins of fruit and plants are where yeast thrives. Yeast is a single-cell fungus that is plentiful all around us. Fruit juices, plant sap, and raw honey, which contain simple sugars, will ferment spontaneously into alcohol in the right environment.

Over millennia, humans have learned how to manipulate the process by using different types of yeast to produce various products. The most well-known strain of yeast is Saccharomyces cerevisiae. This highly cultivated yeast is responsible for the fermentation of most industrial foods and beverages, including beer, wine, and baked goods.

Beer

The discovery of beer production dates back to the Sumerians of Mesopotamia in 3400 BC. Ceramic vessels found in Iran’s Zagros Mountains had beer residue inside.

Beer production begins with malted grain, which gets mixed and crushed into a coarse grist during milling. Next, it goes through mashing, where the grain and water mix with heat. This process breaks the starches down into fermentable sugars. The mixture then undergoes a lautering process, separating the mash into a clear liquid (wort) and residual grain. The liquid wort then gets boiled, and hops are added. The final stages include whirlpooling or recirculation (to remove dense solids), cooling, fermentation, conditioning and filtration.

The broad categories of beer include:

  • Top-fermenting beers like ales ferment at higher temperatures using Saccharomyces cerevisiae. This is the oldest method of fermenting beer.
  • Lagers are bottom-fermenting beers produced by the yeast strain Saccharomyces pastorianus. This fermentation happens at lower temperatures, where yeast consumes more sugars. Thus creating a crisper and lighter style of beer.
  • Wild-fermenting beers such as Lambic beer need a cool environment that yeast and lactic acid bacteria can tolerate. The fermentation of Lambic beer can involve over two hundred organisms, producing a complex flavor profile.

Saké

Saké is an alcoholic rice beverage that originated in China, not Japan, as most people perceive, approximately 7000 years ago in conjunction with rice cultivation. Brewing saké for commercial purposes began somewhere between the 12th and 14th centuries. The technique developed during this period is similar to the methods used today.

The first step in making saké is milling the rice, then soaking and steaming it. Next, koji (a type of mold) is added to convert the starch into fermentable sugars. Adding more rice, water and lactic acid bacteria creates the perfect environment for yeast to thrive. This mixture, known as Shubo, goes into a bigger vessel with more steamed rice, koji-infected rice and water.

Fermentation happens in three to four stages across many weeks at low temperatures between 6-15°C). Consequently, a higher percentage of alcohol develops.

Mead or Simple Sugar Ferments

Mead or honey wine is the oldest and simplest form of fermentation. There are references to it in historical documents of ancient cultures, such as Egyptian, Greek, Hindu, Turkish, North African, Myan and Roman. Essentially, it’s diluted raw honey containing abundant yeast with water. These yeasts become active when the water content is above 17%. The simplicity of mead allows for infinite variations with botanical enhancements. Traditional meads are distinguishable by their plant additions.

Types of mead include:

T’ej is a traditional mead from Ethiopia that uses twigs and leaves of Gesho (shiny-leaf buckthorn and a relative of hops). It can range anywhere between 10% to 40% ABV.

Metheglin is Welsh in origin, meaning honey wine with spices/herbs. Metheglin meads are mostly medicinal in purpose in eastern Europe.

Braggot is a mead that includes hops, sometimes botanicals, or an herbal mix known as Gruit.

Cyser is a mead that uses apple juice rather than water for fermentation.

Melomel is a mead that uses fruit or fruit juice for fermentation.

Pyment is a mead that comes from table grapes or grape juice. 

Cider

Britain is the likely birthplace of cider, which was made from crab apples as long ago as 3000 BC. These apples were inedible due to their high acid and tannin content, yet desirable for cider making.

After the Normans invaded Britain in 1066, cider-making improved. They planted orchards and brought with them better pressing technology. Commercial cider-making increased in England during the 15th and 16th centuries, which was the precursor to the golden age of cider. During this time, the war with France and Spain interrupted the import of wine, brandy and sherry into England. This led to more experimentation with cider, including cross-pollination of apple species and the use of glass and cork.

During the Napoleonic Wars (1792-1815), cider orchards became neglected, and ancient apple cultivars were lost. By the mid-20th century, commercial cider-making had become mundane, and cider consumption had become unfashionable. Today, we are seeing a return to ancient styles of cider-making by artisanal producers. They use century-old cultivars and wild ferments to produce complex and interesting ciders.

Basic cider-making is a pretty straightforward process. The fruit is milled to produce a pomace. It then goes through a press to extract the juice. The juice then goes through fermentation.

Fruit Wine

Fruit wines include a broad range of base ingredients except for grapes. Additionally, mead and cider do not fall under the definition of fruit wine for their independent historical context. Generally, fruit wine is more prevalent in regions or climates where wine grape cultivation can be challenging.

The tradition of fruit wine began with the early settlers. Fruit-based ferments can be made in a few different ways. The most popular way is using syrup that comes from cooking fruit. It’s diluted with water and then goes through fermentation. A more labour-intensive approach is to juice the fruit first and then ferment it. A far easier method is to infuse the fruit into honey water and then ferment it. This method, which can use anything from fruit, flowers, vegetables, herbs, or spices, falls under a more general term: country wine.
