The History and Culture of Coffee Brewing

Coffee, as one of the most popular beverages in the world, has a long and rich history and culture. From 9th century Ethiopia, coffee began to spread around the world and gradually evolved into a global cultural phenomenon.

The Origin and Spread of Coffee

The origin of coffee can be traced back to Ethiopia in the 9th century AD. Legend has it that a shepherd found his flock to be unusually excited after eating a wild berry, so he also tried the berry and found himself energized. This berry is what we know today as the coffee bean.

Over time, coffee spread from Ethiopia to the Arabian Peninsula and into Europe in the 15th century. Coffee quickly became popular in Europe and became an integral part of social and cultural life. In the 17th century, coffee was introduced to the Americas and is now widely grown and consumed worldwide.

The Evolution of Coffee Brewing Technology

Coffee brewing technology is also constantly evolving. Initially, people simply boiled coffee beans and then drank the bitter liquid. Over time, people have invented a variety of coffee brewing tools and methods, such as Turkish coffee pots, French presses, mocha pots, drip coffee makers and so on.

In the 20th century, with the advancement of technology, automatic drip coffee makers came out, which greatly simplified the process of coffee brewing. Today, we already have smart coffee machines like the Breville Precision Brewer Thermal Coffee Maker, which can not only automatically complete the brewing process, but also can be personalized according to the user’s preferences, so that everyone can easily enjoy a professional cup of coffee at home.

Precise Temperature Control (PID)

The Breville Precision Brewer Thermal Coffee Maker uses a PID temperature control system to ensure that the water temperature during the brewing process is accurately and stably maintained between 197-204 degrees Fahrenheit (92-96 degrees Celsius). This temperature range is recognized by professional baristas as the best brewing temperature, which can maximize the flavor of coffee beans. The PID controller continuously monitors and adjusts the water temperature to ensure that the ideal temperature is reached for each brew, thus ensuring the taste and aroma of the coffee.

Adjustable Flow Rate

The Breville Precision Brewer Thermal Coffee Maker offers three different flow rates: fast, medium and slow. Users can choose the appropriate flow rate according to the grind size of the coffee beans and personal taste preferences. Finer ground coffee requires a slower flow rate to ensure adequate extraction, while coarser ground coffee can be brewed at a faster flow rate. This adjustability allows the user to better control the extraction process of the coffee, resulting in the desired coffee flavor.

Dual Filter Baskets

The Breville Precision Brewer Thermal Coffee Maker comes with two filter baskets: a flat bottom filter basket and a cone filter basket. The flat bottom filter basket is suitable for most ground coffee, while the cone filter basket is more suitable for finely ground coffee, which can better extract the aromatic substances of coffee. In addition, both filter baskets are compatible with paper or reusable filters, and users can choose according to their own preferences and environmental protection concepts.

Steep & Release Technology

The Steep & Release technology of the Breville Precision Brewer Thermal Coffee Maker is a patented technology that can intelligently control the water flow when brewing small cups of coffee, extending the contact time between the water and the coffee grounds to ensure that the coffee is fully extracted, thus ensuring that the flavor of the small cup of coffee is also rich and mellow. This technology allows the Breville Precision Brewer Thermal Coffee Maker to maintain consistent extraction results when brewing different cup sizes of coffee, whether it is 1 cup or 12 cups, you can enjoy the same high-quality coffee.

Gold Cup Certified

The Gold Cup mode of the Breville Precision Brewer Thermal Coffee Maker has been rigorously certified by the Specialty Coffee Association (SCA) and meets its Gold Cup standards. This means that when you choose Gold Cup mode, the coffee maker will automatically adjust the water temperature and brewing time to meet the optimal coffee extraction standards defined by the SCA. This ensures that you can easily make delicious coffee at home that meets the standards of professional baristas.


The Breville Precision Brewer Thermal Coffee Maker can not only use its own filter basket and filter, but also compatible with Hario V60, Kalita Wave and other manual filter cups. This means that if you already have your favorite manual filter cup, you can install it directly on the Breville Precision Brewer Thermal Coffee Maker without having to purchase additional accessories. This compatibility gives users greater freedom to choose the brewing method that best suits their preferences and habits.

Automatic Heat Preservation Function

The Breville Precision Brewer Thermal Coffee Maker is equipped with a large capacity thermal carafe, which adopts double-layer vacuum insulation technology to effectively prevent heat loss and keep the coffee warm for a long time.
