What to Check First
Brewer Type and Filter Type
You’ve got a French press. That’s the star here. It uses a metal mesh filter. This lets more oils and fine grounds through than paper filters, giving you a richer cup. Make sure your press is clean.
Water Quality and Temperature
Good water makes good coffee. If your tap water tastes funky, it’ll make your Stumptown taste funky. Filtered water is usually best. For temperature, aim for just off the boil, around 195-205°F. Too hot, and you’ll scorch the grounds. Too cool, and you won’t extract enough flavor. I usually just let my kettle sit for about 30 seconds after it boils.
Grind Size and Coffee Freshness
This is critical for French press. You want a coarse grind. Think coarse sea salt or breadcrumbs. Too fine, and you’ll get sludge in your cup and over-extraction. Too coarse, and it’ll be weak. Stumptown beans are usually roasted within a few weeks. Always check the roast date on the bag. Grind your beans right before brewing for maximum flavor. Seriously, it makes a world of difference.
Coffee-to-Water Ratio
A good starting point is a 1:15 ratio. That means 1 gram of coffee for every 15 grams of water. For a typical 32oz French press, that’s about 55-60 grams of coffee. You can adjust this to your taste. More coffee means a stronger brew. Less coffee means a lighter one. I usually eyeball it a bit, but weighing is more precise.
For the most consistent results, especially when dialing in your ratio, consider using a coffee scale. It takes the guesswork out of measuring your grounds and water.
- Barista-Level Precision: A 0.1g high-precision sensor with a rapid refresh rate responds instantly to changes in weight, helping you achieve consistent results across espresso, pour over, drip coffee, Chemex, V60, and filter coffee brewing.
- Integrated Brew Timer: A built-in count-up and count-down timer tracks bloom, extraction, and espresso shots. Ideal for dialing in espresso, timing Chemex and V60 pour over recipes, or steeping tea. Auto-shutoff helps preserve battery life between brews.
- Durable Waterproof Silicone Cover: The heat-resistant, dishwasher-safe silicone cover helps protect the coffee scale's spacious 5.25" x 5.25" weighing surface from splashes, spills, and hot equipment. The grooved surface provides added stability and makes cleanup quick and easy.
- Versatile Measurement Options: Quick-tare and 6 unit options make it easy to weigh coffee beans, espresso shots, matcha portions, and more. Choose from g, ml, lb, lb:oz, oz, and fl oz for added flexibility in the kitchen and coffee bar.
- Intuitive Design: A bright dual-color LCD display clearly separates weight and timer readings, while simple controls make daily brewing easy. Includes 3 AAA batteries and is backed by 5 years of coverage, with support from our St. Louis-based team whenever you need a hand.
Cleanliness/Descale Status
A dirty French press is a flavor killer. Old coffee oils go rancid and will ruin your fresh Stumptown. Make sure all parts are clean, especially the mesh filter. If you have hard water, you might need to descale your brewer periodically. Check the manufacturer’s instructions for descaling.
Step-by-Step: How to Make French Press Coffee Stumptown
1. Heat your water.
- What it looks like: Water is hot but not vigorously boiling, around 195-205°F.
- Common mistake: Using boiling water. This can scorch the coffee. Let the kettle sit for about 30 seconds after it boils.
2. Grind your Stumptown coffee.
- What it looks like: Coarse, even grounds, resembling sea salt.
- Common mistake: Grinding too fine. This leads to a muddy, bitter cup. Use a burr grinder if possible for consistency.
3. Add grounds to the French press.
- What it looks like: All your coffee grounds are in the bottom of the carafe.
- Common mistake: Not measuring accurately. Use a scale for best results, or a consistent scoop.
4. Add a small amount of hot water (the bloom).
- What it looks like: Just enough water to saturate all the grounds. You’ll see them expand and bubble.
- Common mistake: Skipping the bloom. This releases CO2 and prepares the grounds for even extraction.
5. Stir gently (optional but recommended).
- What it looks like: A quick, gentle stir to ensure all grounds are wet.
- Common mistake: Over-stirring. This can agitate the grounds too much and lead to bitterness.
6. Pour the remaining hot water.
- What it looks like: Water fills the press up to the desired level, covering all the grounds.
- Common mistake: Pouring too quickly. A slow, steady pour helps maintain temperature.
7. Place the lid on, but don’t press yet.
- What it looks like: The plunger assembly is resting on top of the water, creating a seal.
- Common mistake: Pressing down too early. This disrupts the brewing process.
8. Let it steep for 4 minutes.
- What it looks like: The coffee is steeping undisturbed.
- Common mistake: Steeping for too long or too short. 4 minutes is the sweet spot for most roasts.
9. Slowly and steadily press the plunger down.
- What it looks like: The plunger moves down smoothly with minimal resistance.
- Common mistake: Pressing too fast or too hard. This can force fines through the filter and create sediment.
10. Pour immediately.
- What it looks like: All the brewed coffee is out of the press and in your mug.
- Common mistake: Leaving coffee in the press. It will continue to extract and become bitter.
11. Clean your French press.
- What it looks like: All grounds are removed, and the carafe and filter are rinsed thoroughly.
- Common mistake: Not cleaning right away. Dried-on coffee is a pain to remove and affects future brews.
Common Mistakes (and What Happens If You Ignore Them)
| Mistake | What it causes | Fix |
|---|---|---|
| Using stale or pre-ground coffee | Flat, dull flavor, lack of aroma | Buy freshly roasted whole beans and grind just before brewing. |
| Water too hot (boiling) | Scorched, bitter, acrid taste | Let water cool for 30-60 seconds after boiling (aim for 195-205°F). |
| Water too cool (<190°F) | Weak, sour, underdeveloped flavor | Ensure water is properly heated; pre-warm your press. |
| Grind too fine | Muddy coffee, sediment, over-extracted bitterness | Use a coarse grind (sea salt consistency); check your grinder settings. |
| Grind too coarse | Weak, watery, sour coffee | Adjust grinder for a finer, but still coarse, setting. |
| Incorrect coffee-to-water ratio | Too strong or too weak brew | Use a scale to measure coffee and water (1:15 is a good start). |
| Skipping the bloom | Uneven extraction, less complex flavor | Wet grounds with a little water for 30 seconds before adding the rest. |
| Pressing the plunger too fast/hard | Sediment in cup, bitter taste, potential grounds spill | Press slowly and steadily; if you feel high resistance, stop and check. |
| Leaving coffee in the press after brewing | Over-extraction, bitter and stale taste | Decant all brewed coffee immediately into a separate carafe or mugs. |
| Not cleaning the press thoroughly | Rancid oils, off-flavors, dull coffee | Rinse and wash all parts immediately after each use. |
| Using hard or chlorinated tap water | Off-flavors, metallic taste, mineral buildup | Use filtered water for a cleaner, purer coffee taste. |
Decision Rules
- If your coffee tastes bitter, then try a coarser grind or a slightly lower water temperature because these can reduce over-extraction.
- If your coffee tastes weak or sour, then try a finer grind or a longer steep time (up to 4.5 minutes) because this can increase extraction.
- If you see a lot of sediment in your cup, then your grind is likely too fine or you pressed too hard, so adjust your grind or press more gently.
- If your coffee tastes dull, then your beans are probably stale or you’re not using fresh grounds, so ensure you’re grinding right before brewing.
- If your French press is difficult to plunge, then your grind is too fine or the filter screen might be clogged, so check your grind size and clean the filter.
- If you taste metallic notes, then your water quality might be an issue, so try using filtered water.
- If your coffee is too strong, then reduce the amount of coffee grounds you’re using or increase the water volume because this will dilute the brew.
- If your coffee is too weak, then increase the amount of coffee grounds you’re using or decrease the water volume because this will make the brew more concentrated.
- If you want a richer mouthfeel, then stick with the French press because its metal filter allows more oils to pass through.
- If you prefer a cleaner cup with less sediment, then a pour-over or drip machine with a paper filter might be a better choice because they trap more fines.
FAQ
Q: What kind of Stumptown coffee is best for French press?
A: Medium to dark roasts often shine in a French press. Stumptown’s blends like Hair Bender or their single origins can be fantastic. Look for beans with flavor notes that appeal to you.
Q: How much coffee should I use?
A: A good starting point is a 1:15 coffee-to-water ratio by weight. For a 32oz press, that’s about 55-60 grams of coffee. Adjust to your personal taste.
