History and Cultural Significance

The traditional corn beer known as Chicha has deep roots in the Andes and maintains a profound cultural relevance in Peru, serving both historical and social functions within communities from ancient to modern times.

Origins in the Andes

Chicha's beginnings trace back to the Andean civilization, long before the rise of the Incan Empire. Historians pinpoint the origin of this fermented beverage to indigenous cultures that thrived in what is now known as the Sacred Valley. These early versions of Chicha were integral to communal practices and were often used to spiritually communicate with the gods.

Chicha in Incan Society

Within the Incan Empire, Chicha gained prominence as a ritualistic drink and a staple among the Incas. It was used ceremoniously by Inca Tupac Yupanqui, the tenth Sapa Inca of the Incan Empire and by other leaders as offerings to the Sun God, Inti, often in sacred sites such as Machu Picchu. The beverage further symbolized social unity, was consumed at communal gatherings, and played a key part in religious ceremonies.

Today, Chicha remains a significant part of Peruvian culture, especially in the Peruvian Andes. Local chicherias—establishments dedicated to brewing and serving Chicha—can be found, where the drink continues to foster a sense of community. With a strong link to indigenous Quechua traditions, modern Chicha underscores the resilience of Andean customs in contemporary Peru.

Ingredients and Variations

Fermenting Chicha involves selecting the right type of maize and incorporating various regional ingredients that offer a spectrum of flavors and aromas, resulting in a beverage that's both traditional and versatile.

Traditional Maize Selection

The cornerstone of Chicha is maize, specifically Peruvian corn, which imparts the beverage's characteristic sweetness and body. Traditional Chicha utilizes purple corn, known for its deep hue and sweet flavor. Brewers often prefer non-malted grains, relying on the natural enzymes in saliva or a malted barley addition to break down the starches during the mashing process.

Regional Variants and Additions

Regional adaptations of Chicha allow for the inclusion of other ingredients such as apple, ginger, pineapple, and strawberries, offering a wide array of flavor profiles. In some regions, spices like coriander and cloves, or herbs like chamomile, are infused to create unique twists on the traditional recipe, making each variant distinct in taste.

• Additives for Sweetness: Corn sugar or brown sugar is sometimes added to the mixture to enhance its fermentable sugars.

• Fruit Varieties: Commonly added fruits and ingredients for regional Chicha include:

  • Apples

  • Pineapple

  • Ginger

  • Strawberries

Alternative Starch Sources

While maize is the traditional staple, contemporary versions of Chicha might include other grains like barley, particularly malted barley, to introduce different flavor notes and assist in fermentation. Brewers may experiment with a variety of starch sources, adapting the ancient methods to craft a Chicha that respects tradition but also mirrors today's eclectic taste preferences.

The Fermentation Process

Fermenting chicha involves converting the starches from corn into fermentable sugars, using either natural enzymes found in saliva or modern brewing techniques. The fermentation step is critical in chicha production, determining the flavor and alcohol content of the final beverage.

Natural Fermentation

In natural fermentation, the environment's native yeast interacts with the wort—the liquid extracted from the mash—to start fermentation. Natural enzymes within the yeast break down starches into fermentable sugars, producing alcohol and carbon dioxide in the process. This method relies on the spontaneous activity of wild yeast present in the air and on the brewing ingredients.

Mucking and Chewing Technique

The traditional method of fermenting chicha, still seen in some cultures, is known as the mucking and chewing technique. This involves individuals chewing corn to break down the starches using the natural enzymes in their saliva. The masticated corn is then spit into a container where it's left to ferment. Salivary enzymes convert the starches into sugars, which are then fermented by naturally occurring yeast.

Modern Fermentation Methods

Modern homebrewers often use ale yeast to ferment chicha. They skip the chewing process by employing a mash to convert the corn starches into sugars using controlled enzyme reactions. After mixing with water and heating, the mixture, now called wort, is inoculated with selected yeast strains. This controlled environment promotes consistent fermentation and predictable flavor profiles.

Preparing for Fermentation

To successfully ferment chicha, careful preparation of the maize, managed boiling and cooling, and the appropriate use of sugars and spices are essential steps in the process.

Processing the Maize

The initial step involves grinding or finely processing the maize. Traditional methods required the maize to be chewed by brewers to mix with saliva, which starts the breakdown of starches. However, modern methods sometimes use malt to achieve the same effect. The malted maize must then be dried, ensuring that it is suitable for fermentation.

Boiling and Cooling

Once processed, the maize is combined with water and brought to a boil. This step usually lasts for several hours and serves to sterilize the mixture and further convert starches into fermentable sugars. After boiling, it is critical to cool the mixture rapidly to a temperature suitable for fermentation. Some brewers immerse the brew pot in an ice water bath to expedite cooling.

The Role of Sugar and Spicing

Sugar, specifically corn sugar or sometimes brown sugar, is often added just before or after boiling to provide additional sweetness and aid in the fermentation process; this is known as priming. Spices, such as cinnamon, can be added to impart flavor. Traditional chicha de jora, a corn-based beer, may also include spices during the fermentation phase to add distinct flavor profiles. It is a red flag in the brewing process to skip the calibration of sugars and spices as they significantly impact the end product.

Brewing Techniques and Equipment

In creating chicha, brewers have the option to follow time-honored methods or adapt to modern brewing practices, each requiring specific equipment and a keen understanding of the fermentation process.

Traditional Techniques

Historically, chicha was made using a traditional method that is both labor-intensive and deeply rooted in indigenous culture. Brewing began with malting corn, which involved soaking it and allowing it to germinate. Grains would then be chewed by brewers, utilizing natural enzymes in saliva to break down starches and begin fermentation. The chewed corn would then be spit into vessels, often clay pots or other traditional forms of pottery, and combined with water to ferment. Key items in traditional brewing include:

• Germination trays: For sprouting corn.

• Clay pots: Used for fermentation, embracing the natural materials and methods of ancient brewers.

Modern Brewing Practices

Modern brewers of chicha may replace the chewing step with a malting process using malted barley to imitate the enzyme action saliva once provided. Homebrew enthusiasts and craft beer producers often use a standard brewing set up for making chicha, including:

• Stainless steel kettles: For boiling the wort and ensuring sanitary conditions.

• Fermentation buckets: With airlocks to control the fermentation environment.

• Corn sugar: Often used for priming before bottling.

Unlike some IPA and other beer styles, chicha doesn't typically navigate extreme hop flavors but rather focuses on the unique, earthy character of corn. Modern tools and techniques allow brewers to maintain consistency and control over the brewing process while honoring the cultural significance of this time-honored beverage.
