How to Brew Pour-Over Coffee Using SCAE Standards

If you’ve ever wondered why your pour-over coffee tastes weak, bitter, or just off, the issue likely lies in one or more key variables: water temperature, grind size, bloom time, or brew ratio. Mastering these fundamentals is how specialty coffee lovers achieve clarity, balance, and sweetness in every cup.

To brew a balanced two-cup pour-over using the SCAE standard method, aim for a brew ratio of around 1:17 to 1:18, use water between 85–93°C, and bloom the coffee for 20 seconds with 10% of your total water. Follow our step-by-step guide below for consistent results.

Why Pour-Over Coffee Became a Global Standard

Pour-over coffee isn’t just a trend—it’s the brewing method that defined the third wave of coffee. Thanks to its clean cup, clarity of flavor, and control over every variable, it became the go-to technique for specialty coffee professionals and enthusiasts alike. While methods like siphon or French press have their fans, pour-over offers unmatched precision and a clean profile that highlights the bean’s origin and processing.

This method owes much of its global popularity to a 1908 German innovation. Melitta Bentz, frustrated with the mess and taste of cloth filters, invented the first paper coffee filter. On June 20, 1908, she patented a copper dripper with a single hole and a corrugated base—the world’s first paper filter dripper. Her design laid the foundation for the pour-over technique we use today.

The Tools You’ll Need for SCAE-Standard Pour-Over

To follow this guide, you’ll need the following equipment:

• Bonavita gooseneck temperature-controlled kettle (noted for ±1°C accuracy)
• Electronic scale
• Melitta-style pour-over dripper (we used a ‘’ or ‘Free Cup’ style)
• Coffee server or carafe
• Paper filters (Melitta No.4 recommended)
• Hand grinder or electric burr grinder

While premium gear helps, the principles remain the same regardless of brand. What matters most is controlling the variables.

How to Choose Your Coffee-to-Water Ratio

Your brew ratio determines strength and extraction balance. Here are the tested ratios from the source for common serving sizes:

• 150ml porcelain cup: 160ml water + 9g coffee (1:17.8)
• 300ml porcelain cup: 321ml water + 18g coffee (1:17.8)
• 360ml porcelain cup: 482ml water + 27g coffee (1:17.8)

Most pour-over specialists aim for a 1:15 to 1:18 ratio depending on roast level and desired strength. The examples above sit comfortably within specialty coffee norms.

Step-by-Step: Brewing Two Cups via Pour-Over

Follow these steps for a controlled, SCAE-aligned brew:

1. Fold the Filter

Use a Melitta No.4 filter—its reinforced sides and base help with stability. Fold the thickened seam edges inward and place the filter into your dripper with the folded side facing up. This ensures a snug fit and reduces bypass.

2. Grind the Coffee

Grind fresh coffee beans to a consistency similar to table sugar—medium-fine, around the same as a commercial drip grind but slightly finer. Consistent particle size is crucial for even extraction.

3. Pre-Wet the Filter

Place the dripper on your server, add hot water to saturate the filter, and let it drain. This removes paper taste and preheats your equipment. Always perform this step—even if your filter claims to be “odorless.”

4. Add Coffee Grounds & Bloom

Zero your scale, then add 18g of coffee to the dripper. Gently tap to level the bed. Start your timer and pour 32g of water (10% of your target brew water) over the grounds. Let it bloom for 20 seconds. This releases CO₂ and prepares the coffee for even extraction.

5. Pour in Stages

After the bloom, pour the remaining 289g of water (for a total of 321g) using steady, circular motions. Start from the center and spiral outward without hitting the filter walls. Avoid dry spots and don’t pour so fast that the water channels through.

6. Final Drip & Serve

Once all the water has been added, let the coffee fully drain—this should take roughly 3.5 minutes total. Avoid pouring out any foam from the bottom of the dripper, as it can carry fine particles. Serve and enjoy!

Water Temperature: Why It Matters

The ideal water temperature range for pour-over is 85–93°C. Lighter roasts often perform better at the higher end of the range to highlight acidity and complexity, while medium to dark roasts can use slightly cooler water to reduce bitterness. Adjust based on bean origin, roast level, and taste preference.

Frequently Asked Questions

What is the ideal coffee-to-water ratio for pour-over?

For balanced extraction, use a brew ratio between 1:15 and 1:18. The examples in this guide use 1:17.8—for instance, 18g coffee to 321ml water for a standard two-cup brew.

What water temperature should I use for pour-over coffee?

Specialty guidelines recommend a range of 85–93°C. Lighter roasts benefit from hotter water (closer to 93°C), while darker roasts can use water closer to 85–90°C to avoid over-extraction and bitterness.

How long should a pour-over brew take?

Total brew time—including bloom—should be around 3 to 3.5 minutes. If it’s much faster, your grind may be too coarse; if slower, your grind might be too fine or your pour too slow.

Do I really need to bloom my coffee?

Yes. Blooming (pouring a small amount of hot water over the grounds and letting it sit for 20–30 seconds) releases trapped CO₂, which interferes with even extraction. Skipping it can lead to uneven flavor and a flat cup.

Can I use any dripper for SCAE-style pour-over?

Yes, but cone-shaped drippers with a single hole or spiral ridges (like the Melitta-style or ‘’) offer the best control for beginners. The key is consistency in water flow and contact time.
