How to Brew Coffee: Hand Pour-Over Methods Explained

When a Dutch barista introduces his micro coffee bar with “Welcome to my little coffee setup,” you know you’re about to see something unconventional. He’s not there to serve drip coffee — he’s showcasing a carefully constructed brew that reflects both cupping body and filter clarity. This is where innovation meets the pour-over, and today we’re breaking down exactly how top competitors are rethinking manual brewing.

To answer the big question: How do leading baristas actually brew coffee manually these days? They combine gear (like AeroPress and Chemex filters), use precise parameters (18g coffee to 300g water, 93°C, 5:30 brew time), and highlight unique processing — like 20-hour anaerobic fermentation — to achieve specific profiles such as apple-like acidity, cinnamon sweetness, and medium-light body.

The Dutch Barista’s Hybrid Brew: Body Meets Clarity

A Dutch competitor kicks off his routine with a bold statement: “Every part of modern coffee is innovating.” For his routine, he selects a Costa Rican coffee from the Diamante Estate — a Catuai and Caturra hybrid, processed with anaerobic fermentation while retaining mucilage for 20 hours. That process yields a cinnamon-like wet aroma.

But it’s not just about the beans. His real innovation? A custom brew method that fuses the full-bodied feel of espresso with the clean cup of a Chemex. How? By using an AeroPress-like manual espresso maker combined with Chemex paper filters. His recipe: 18g coffee, 300g water, a water pH of 7.1, 120 ppm hardness, brewed at 93°C. Total brew time is 5 minutes 30 seconds with constant stirring for even extraction. The final cup delivers light apple acidity, a cinnamon aftertaste, and medium-light body. The entire procedure takes him 9 minutes 40 seconds.

Sarah Anderson’s Wild Card: The Mother of Arabica

Ranking fourth in the competition was Sarah Anderson from the U.S.-based roastery ‘Intelligentsia’. She brought something truly rare to the table: a coffee made from the species Eugenioides — often referred to as the ‘mother of Arabica.’

This bean is unusual, offering intense sweetness paired with delicate acidity. Its annual production? Just 200 pounds, though it’s on the rise. Grown in a greenhouse under controlled conditions, the cherries were fermented in stainless steel tanks. Sarah and her team at Intelligentsia in Los Angeles spent over 80 roasting sessions dialing in the profile. Some early research even involved collaboration with Copenhagen’s ‘Unity Coffee’.

For brewing, she used the ALTOAIR paper filter pour-over device. Her parameters: 19g coffee, 300g water, total brew time 8 minutes 30 seconds. “Low coffee dose highlights brightness,” she explained. She split the coffee and hot water into three cups to let it settle, stirred again after 1 minute 30 seconds, then poured through the filter in stages. Her goal? To keep each cup surprising. “I want my guests to always experience something new,” she said. And to the judges: “You deserve the best — not something you’ve had before.”

What Makes These Methods Different?

Compared to standard pour-over routines, these competitors aren’t just tweaking recipes — they’re engineering entire systems. Key variables include:

• Bean Processing: Anaerobic fermentation, extended mucilage retention (20 hrs), and rare species like Eugenioides.
• Brew Devices: Unusual combinations like AeroPress + Chemex filters, or staged pouring through ALTOAIR filters.
• Brew Ratios: Standard is around 1:16 (e.g., 18g coffee → 300g water); these competitors stick close but add their own variables.
• Water Chemistry: Not just temperature (93°C), but also pH (7.1) and hardness (120 ppm).
• Stirring & Timing: Constant stirring during extraction (5:30), or staged stirring (1:30, then pour in steps).
• Total Time: Ranges from 8:30 to nearly 10 minutes for full process completion.

Frequently Asked Questions

What is anaerobic fermentation in coffee processing?

Anaerobic fermentation means coffee cherries are fermented in an oxygen-free environment, often for extended periods like 20 hours. This process can enhance flavors such as cinnamon, fruitiness, or sweetness, as seen in the Costa Rican Diamante Estate beans used by the Dutch barista.

What’s special about the Eugenioides coffee species?

Eugenioides is considered the ancestor of modern Arabica and is known for intense sweetness and delicate acidity. It’s extremely rare, with global production as low as 200 pounds per year, and requires careful greenhouse cultivation and fermentation.

How is the Dutch barista’s method different from regular pour-over?

Instead of using a standard V60 or Kalita, he combined an AeroPress-like device with Chemex paper filters to achieve both body (like espresso) and clarity (like Chemex). He also stirred continuously during a 5:30 extraction with precise water chemistry (pH 7.1, 120 ppm hardness).

Why did Sarah Anderson split her coffee into three cups before brewing?

By separating the coffee and water into three cups, letting it settle, then stirring and pouring in stages, she enhanced clarity and brightness. This method highlights the unique qualities of the rare Eugenioides species and keeps the cup experience fresh.

What water temperature and pH do these baristas use?

Most use 93°C water. The Dutch barista specifies a water pH of 7.1 and hardness of 120 ppm — parameters that go beyond typical home brewing but influence flavor clarity and body.

How long does anaerobic fermentation usually last for coffee?

In this case, 20 hours. But durations can vary; the key is controlling oxygen levels and often using mucilage retention to boost fermentation-derived aromas like cinnamon or tropical fruit.
