A Brief History of Cold Brew: From Ancient Times to Modern Day

Cold brew coffee has been around for centuries, with early records dating back to 17th-century Japan, where they brewed tea using cold water. Historically, cold brew was also popularized in South America, where it was called “toddy” and used as a concentrate mixed with milk.

However, it wasn’t until the 1960s that cold brew coffee gained popularity in the United States. Even then, it remained a niche product until the turn of the century, when it exploded onto the scene, becoming a staple in many cafes and households.

The Science Behind Cold Brew

The cold brew process involves steeping coffee grounds in cold water for an extended period, typically 12-24 hours. This extended steeping time allows the water to extract more flavor compounds from the coffee grounds, resulting in a smoother and less acidic cup of coffee. Unlike hot coffee, which can be bitter and burnt-tasting if over-extracted, cold brew has a more balanced and nuanced flavor profile.

But what’s happening on a chemical level during the cold brew process? When coffee is brewed with hot water, the heat causes the coffee solids to dissolve quickly, resulting in a rapid extraction process.

However, hot water also extracts acids and oils that can result in a bitter taste. With cold brew, the slower extraction process allows for a more gentle and complete extraction of the coffee’s soluble compounds. 

Cold Brew Technology: From Filtration to Nitro

As cold brew has grown in popularity, so too has the technology used to make it. Early iterations of cold brew involved steeping coffee grounds in a large container and then straining out the liquid using a cheesecloth or coffee filter. However, this method can be messy and time-consuming, leading to innovations in cold brew filtration systems.

One of the most popular filtration methods is the Toddy system, which uses a reusable felt filter to catch coffee solids while allowing the liquid to pass through. Other systems, such as the Hario Mizudashi, use a fine mesh filter to achieve similar results. These filtration systems make cold brew production more efficient and less labor-intensive, allowing cafes and households to produce large batches of cold brew with ease.

Another recent innovation in cold brew technology is nitro cold brew. Nitro cold brew involves infusing cold brew coffee with nitrogen gas, which creates a creamy, foamy texture similar to a pint of Guinness beer.

The nitrogen bubbles also enhance the flavor and aroma of the coffee, resulting in a unique and luxurious drinking experience. Nitro cold brew has become a popular option at many cafes and restaurants, and some companies have even created canned versions of the beverage for on-the-go enjoyment.

The Future of Cold Brew Technology

As the demand for cold brew continues to grow, we can expect to see further innovation in cold brew technology. Some companies are exploring ways to incorporate sustainable and eco-friendly practices into cold brew production, such as using solar-powered brewing equipment or upcycling coffee waste into fertilizer. Others are experimenting with new flavors and ingredients to create unique and exciting cold brew products.

One potential area of growth for cold brew technology is automation. Currently, most cold brew production involves manual labor, such as measuring out coffee grounds and pouring water. However, there is potential for automated systems that can streamline the process and ensure consistency in flavor and quality. This could lead to increased efficiency and lower production costs, making cold brew more accessible to a wider audience.
