What is the ideal water temperature for brewing coffee?
The ideal water temperature for brewing coffee is between 195°F and 205°F. This temperature range allows for the optimal extraction of flavors and oils from the coffee beans. If the water is too hot, it can burn the coffee, resulting in a bitter taste. On the other hand, if the water is too cold, it can lead to under-extraction, resulting in a weak or sour taste.
To achieve the ideal water temperature, cafes often use specialized equipment, such as temperature-controlled water heaters or thermometers. Baristas may also use techniques like pre-heating the brewing equipment or adjusting the grind of the coffee beans to ensure the perfect temperature.
What is the difference between Arabica and Robusta coffee beans?
Arabica and Robusta are the two main species of coffee beans. Arabica beans are considered to be of higher quality and have a more delicate flavor, with notes of fruit and floral hints. They are grown at high altitudes and require cooler temperatures, which makes them more expensive to produce. Robusta beans, on the other hand, have a bolder and more bitter flavor, with a higher caffeine content. They are easier to grow and more disease-resistant, making them a popular choice for instant coffee and espresso blends.
Cafes often choose to serve Arabica beans due to their superior flavor profile. However, some cafes may offer Robusta-based blends as a more affordable option or to cater to customers who prefer a stronger, more bitter taste. Baristas may also experiment with blends of Arabica and Robusta beans to create unique flavor profiles.

Cafes store their coffee beans in a cool, dry place, away from direct sunlight and moisture. This helps to preserve the flavor and aroma of the beans, which can be affected by heat, light, and humidity. Cafes may also use specialized storage containers, such as airtight bins or bags, to keep the beans fresh.
To ensure optimal freshness, cafes often store their coffee beans in small batches, which are used within a few days of opening. This helps to prevent the beans from becoming stale or developing off-flavors. Baristas may also rotate the coffee beans regularly to ensure that the oldest beans are used first.
What is the difference between a pour-over and a French press?
A pour-over and a French press are two popular brewing methods used in cafes. A pour-over involves slowly pouring hot water over ground coffee beans in a filter, which allows for a clean and nuanced extraction of flavors. A French press, on the other hand, involves steeping coarse coffee grounds in hot water and then pressing the grounds to the bottom of the container to separate the liquid.
The main difference between the two methods is the level of immersion and the resulting flavor profile. Pour-over coffee is often described as bright and acidic, with a lighter body, while French press coffee is often described as rich and full-bodied, with a heavier body. Cafes may offer both brewing methods to cater to different customer preferences.
How do cafes create unique coffee blends?
Cafes create unique coffee blends by combining different coffee beans from various regions and farms. This allows them to create complex and balanced flavor profiles that showcase the characteristics of each bean. Baristas may also experiment with different roast levels, brewing methods, and ratios of Arabica to Robusta beans to create unique blends.
To develop a new blend, cafes may start by tasting and evaluating different single-origin coffees, looking for beans with unique flavor profiles and characteristics. They may then combine these beans in different ratios and roast levels to create a blend that meets their desired flavor profile. The resulting blend may be adjusted and refined over time based on customer feedback and sales data.
