The Pour Over Method: A Delicate Art of Brewing Coffee

The pour over method is one of the most appreciated ways of brewing coffee, especially among those who enjoy clean and balanced flavors. This technique allows for more control over the extraction, highlighting notes and nuances that are often lost with other brewing methods. Despite its simplicity, it requires precision in grind size, water temperature, and pouring time to achieve a perfectly balanced cup.

What is the Pour Over Method?

The pour over method involves pouring hot water in a controlled manner over ground coffee placed in a filter, allowing the liquid to pass slowly through the coffee and drip into a carafe or cup. Unlike other systems such as the French press, where the coffee is brewed by immersion, the pour over method uses filtration, resulting in a cleaner cup with a well-defined acidity.

There are many variations of the pour over method, with some of the most popular being the Hario V60, Chemex, and Origami. Each has slight differences in the filter design and extraction process, but the basic principle remains the same.

Materials Needed

To make a great pour over coffee, you'll need the following items:

1. Whole Coffee Beans (preferably freshly roasted)

Using whole coffee beans is essential to maintain freshness and enhance flavors. Freshly roasted coffee retains its oils and aromatic compounds better, resulting in a more flavorful cup with rich nuances. Ideally, the coffee should be roasted within the last 10 to 15 days, as it starts losing flavor after that. Whenever possible, purchase coffee from specific origins, as each region has unique notes that can be accentuated with the pour over method.

2. Coffee Grinder (medium or medium-fine grind)

The grinder is another crucial element. To prepare a good pour over coffee, it's important to have an even grind. A burr grinder (instead of a blade grinder) is best for ensuring consistency. The grind should be medium or medium-fine, similar to the texture of table salt. A grind that's too coarse will result in under-extraction, while one that's too fine will cause the water to pass through too quickly, yielding a weak cup. Finding the right grind ensures a more balanced extraction.

3. Filtered Water

Water is an essential component of coffee, making up about 98% of your cup. Using filtered water is crucial as it removes impurities and minerals that could affect the taste. Tap water may contain chlorine, minerals, and other compounds that negatively impact flavor. Filtered water also allows for a more efficient extraction, giving the coffee a cleaner and smoother taste. If possible, use spring or bottled water, as they have a more balanced mineral content for optimal extraction.

4. Dripper (Hario V60, Chemex, Origami, etc.)

The dripper is the device where you’ll place the ground coffee and filter. There are various options on the market, with Hario V60, Chemex, and Origami being the most popular. Each dripper has its own characteristics, but they all function under the same principle of controlled pouring. The Hario V60 is known for its cone shape, allowing for faster extraction, while the Chemex produces a cleaner cup thanks to its thicker filters. Regardless of which dripper you choose, it will be the central element of the process.

5. Paper Filters Specific to the Dripper

Paper filters are necessary to prevent coffee grounds from mixing with the brewed liquid. It’s important to use filters designed for each type of dripper, as they are tailored to fit the device and ensure proper filtration. Chemex filters are thicker than Hario V60 filters, resulting in a cleaner cup. Be sure to rinse the filters with hot water before use to remove any paper residue and maintain the temperature of the dripper.

6. Carafe or Cup to Collect the Coffee

A suitable carafe or cup is important for receiving the brewed coffee. It’s recommended to use a glass or ceramic carafe, as these materials do not alter the flavor of the coffee and maintain the liquid at a more stable temperature. If using a cup, make sure it’s large enough to avoid spills during extraction. A carafe with a spout also facilitates a more controlled pour, which is essential for an even extraction.

7. Digital Scale

A digital scale is an essential tool for precision in the brewing process. The coffee-to-water ratio directly affects the flavor of your cup, so measuring the right amounts of coffee and water is critical. A recommended ratio is 1:15 to 1:17, meaning for every gram of coffee, use 15 to 17 grams of water. The scale also helps monitor the brewing time.

8. Gooseneck Kettle

A gooseneck kettle is a very useful tool for pouring water in a controlled manner. Its long and narrow spout allows for precise, uniform pouring, which helps evenly saturate the coffee and extract flavors in a balanced way. Most gooseneck kettles also have temperature control, ensuring the water is at the ideal brewing temperature.

9. Timer

Extraction time is critical for a good pour over coffee. A timer will help you track the pouring time and ensure the process lasts between 2:30 and 4:00 minutes, depending on your method and grind. Controlling the time allows for more accurate extraction and prevents over-extraction (which can lead to bitterness) or under-extraction (which results in weak or sour coffee).

Step-by-Step Guide to Preparing Pour Over Coffee

1. Measure and Grind the Coffee

The recommended ratio is 1 gram of coffee for every 15-17 grams of water. For example, for a cup (250 ml of water), use 15-16 grams of coffee. Adjust based on your taste. The grind should be medium or medium-fine, similar to the texture of table salt.

2. Heat the Water

The ideal temperature is between 92 and 96°C. If you don't have a thermometer, bring the water to a boil and wait 30-45 seconds before pouring.

3. Prepare the Filter and Dripper

Place the filter in the dripper and rinse it with hot water. This removes paper residue and warms the dripper, ensuring a more even extraction. Discard the water before adding the ground coffee.

4. Pre-wet the Coffee Grounds (Blooming)

Pour double the amount of water as coffee (e.g., if you used 15g of coffee, pour 30g of water) in a circular motion over the coffee grounds and let it rest for 30-45 seconds. This step releases trapped gases and improves extraction.

5. Pour the Rest of the Water in Intervals

Pour the water slowly in circular motions, avoiding the edges of the filter. Ideally, do this in two or three intervals, allowing the coffee to hydrate evenly.

6. Wait for Full Extraction

The total process should take between 2:30 and 4:00 minutes, depending on your method and grind. If it takes too long, try a coarser grind; if it’s too quick, use a finer grind.

7. Enjoy Your Coffee

Once fully filtered, remove the dripper and gently swirl the carafe or cup to mix the flavors. Voilà! Enjoy your pour over coffee with all its nuances and aromas.
