Essential Equipment
- Drip coffee maker or pour-over cone
- Fresh coffee beans (ideally used within 2-3 weeks of roasting)
- Paper filters (pre-rinsed to remove paper taste)
- Burr grinder (for consistent grind size)
- Filtered water
- Scale (recommended) or measuring spoons
Step-by-Step Brewing Guide
- Prepare Your Equipment
- Fill your water reservoir with filtered water
- Place a paper filter in the brew basket
- Preheat your carafe/mug with hot water (discard before brewing)
- Measure & Grind Coffee
- Weigh coffee according to the calculator's recommendation
- Grind to medium consistency (similar to sea salt)
- Add ground coffee to the filter and gently shake to level the bed
- Optimize Your Brew (For Pour-Over or Pre-Infusion Machines)
- Start with a "bloom" phase: pour just enough water to wet all grounds
- Let it expand for 30 seconds to release carbon dioxide
- This improves extraction and prevents bitter flavors
- Complete the Brewing Process
- For automatic machines: Start the brew cycle
- For manual pour-over: Continue pouring in slow spirals from center outward
- The total brew time should be around 4-5 minutes for optimal extraction
- Serve Immediately
- Remove the filter when brewing completes
- Transfer coffee to a thermal carafe if not serving right away
- Avoid leaving coffee on a warming plate for extended periods
Troubleshooting Your Brew
| Problem | Likely Cause | Solution |
|---|---|---|
| Bitter taste | Over-extraction or water too hot | Use slightly coarser grind or reduce water temperature |
| Weak/watery coffee | Under-extraction or too little coffee | Use more coffee or slightly finer grind |
| Sour taste | Under-extraction or water too cool | Use water between 195-205°F (90-96°C) |
| Inconsistent flavor | Uneven extraction | Pour water evenly across grounds |
| Brew too slow | Grind too fine or filter clogging | Use coarser grind or different filter |
Pro Tips for Better Drip Coffee
- Water quality matters: Coffee is 98% water-filtered water dramatically improves flavor
- Temperature control: The ideal brewing temperature is 195-205°F (90-96°C)
- Fresh is best: Use beans within 2 weeks of roasting for optimal flavor
- Pre-infusion mode: If your machine has this feature, enable it for better extraction (hold the brew button for 5 seconds on Bonavita machines)
- Clean regularly: Descale your machine monthly to prevent mineral buildup and maintain flavor
Customize Your Experience:
The coffee calculator provides an excellent starting point, but feel free to adjust ratios to match your taste preferences. Remember that bean origin, roast level, and grind size all affect flavor. Use this guide as a foundation, then experiment to discover your perfect cup!
