Making pour-over coffee is one of the most rewarding ways to enjoy your morning cup. Unlike automatic drip machines, pour-over brewing puts you in control of every single variable—grind size, water temperature, ratio, and flow rate.
While it might look like a complex chemistry experiment, brewing pour-over coffee boils down to a few fundamental rules. Once you understand how these variables interact, you can unlock the full flavor potential of any coffee bag.
In this beginner's guide, we walk you through everything you need to know to get started.
The Four Fundamentals of Pour-Over Coffee
1. Brew Ratio: The Golden Rule
A brew ratio is the relationship between the weight of your coffee grounds and the weight of your brewing water. In specialty coffee, we always measure in grams for precision.
The standard starting ratio is 1:16 (1g of coffee for every 16g of water).
- For a single cup: 15g of coffee to 250g of water.
- For two cups: 30g of coffee to 500g of water.
Adjusting the ratio is simple: if your coffee feels too strong, try a 1:17 ratio; if it feels weak, try a 1:15 ratio.
2. Grind Size: The Gatekeeper of Time
Grind size dictates how quickly water flows through the coffee bed and how fast extraction occurs.
- Too Fine: Water flows too slowly, leading to over-extraction. The coffee will taste bitter and dry.
- Too Coarse: Water drains too quickly, leading to under-extraction. The coffee will taste sour, salty, and watery.
- For most pour-overs, aim for a medium-fine grind size, resembling coarse sand or table salt.
3. Water Quality & Temperature
Coffee is 98% water, so your water source matters.
- Source: Avoid distilled water (it lacks minerals needed for extraction) and hard tap water (it dulls flavor). Use filtered water.
- Temperature: The ideal extraction range is 90°C to 96°C. If you don't have a thermometer kettle, bring water to a boil and let it sit off the heat for 30 to 45 seconds.
4. The Pouring Technique
Pouring is not just about dumping water in. It controls the agitation of the grounds.
- Bloom: Always start with a bloom pour. Pour double the weight of your coffee dose (e.g., 30g of water for a 15g dose) and wait 45 seconds. This lets carbon dioxide escape, preventing channeling.
- Concentric Spirals: Pour in slow circles, moving from the center out and back. This stirs the grounds gently and extracts flavor compounds evenly.
Recommended Starter Setup
To brew consistent pour-over coffee, we recommend investing in these three essential tools:
- A Gooseneck Kettle: Allows you to pour with surgical precision.
- A Digital Scale: Essential for measuring your ratio and tracking brew time.
- A Burr Grinder: Blade grinders chop coffee into uneven chunks; burr grinders ensure uniform extraction.
