French press brewers are tested similarly to standard drip coffee makers, starting with hand-washing and drying. A specific brewing ratio of 4 ounces of ground coffee to 32 ounces of water is used for French press brewing. Hot water at 203 degrees F (95 degrees C) is added to the brewing chamber, stirred with the grounds, and left to sit for 4 minutes before plunging and pouring a sample cup. The brewed coffee is then tested using a pocket reflectometer to measure the percentage of total dissolved solids, which helps calculate the extraction percentage. Ideally, the extraction percentage should fall between 19% and 22%, indicating a well-brewed cup of coffee.
Various French press coffee makers were tested for their extraction percentage, with results as follows:
– Bodum Chambord French Press: 21%
– Bodum Brazil French Press: 19%
– Mueller French Press: 27%
– Hamilton Beach French Press: 23%
– Coffee Gator French Press: 19%
– Veken French Press: 20%
– Frieling French Press: 19%
– Kona Press: 17%
– SterlingPro French Press: 18%
– OXO Brew Venture French Press Coffee Maker: 21%
Although the extraction percentage range of 19% to 22% is considered ideal, it does not guarantee delicious coffee on its own. The ultimate test lies in the taste of the brewed coffee. The extraction percentage serves as a strong indicator of the quality of the coffee, but personal preference also plays a significant role in determining the perfect cup of French press coffee.
By following a consistent testing method and evaluating the extraction percentage of various French press coffee makers, it is possible to determine which products produce the best-brewed coffee. The testing process involves specific brewing ratios, water temperature, brewing time, and measuring the total dissolved solids in the brewed coffee. The results provide insight into the effectiveness of different French press coffee makers and help consumers make informed decisions when choosing a product that best suits their preferences.
In conclusion, the testing of French press brewers involves a detailed process of evaluating their extraction percentage to determine the quality of the brewed coffee. While the ideal range falls between 19% and 22%, other factors such as taste preferences also play a role in determining the best cup of coffee. By conducting these tests consistently and analyzing the results, consumers can identify high-quality French press coffee makers that produce delicious and well-extracted coffee. Ultimately, the goal is to find a French press brewer that meets both technical standards and personal taste preferences for the perfect cup of coffee at home.
