French Press Basics
The French press, also known as a press pot or plunger pot, is one of the simplest and most effective ways to brew coffee. Invented in the 1920s, this immersion brewing method produces a rich, full-bodied cup with more oils and fine particles than filtered methods.
Why French Press?
- Full flavor extraction - The metal mesh filter allows natural oils to pass through
- No paper taste - Unlike drip coffee, there's no paper filter to absorb flavors
- Simple process - No electricity required, minimal parts to clean
- Affordable - Quality French presses are inexpensive and last for years
- Portable - Great for camping, travel, or office use
What You'll Need
To brew excellent French press coffee, you need just a few key items:
- French press - A quality press with a tight-fitting plunger
- Coarsely ground coffee - Pre-ground or freshly ground beans
- Hot water - Just off the boil (195-205°F / 90-96°C)
- Timer - For consistent results
- Scale (optional but recommended) - For precise measurements
For beginners, the Bodum Chambord is a classic choice that's been trusted by coffee lovers for decades. Its borosilicate glass carafe and stainless steel frame offer durability and a timeless design.
The Perfect French Press Technique
Preheat Your Press
Fill your French press with hot water and let it sit for 30 seconds. This keeps your coffee hot during brewing. Discard the water before adding coffee.
Measure Your Coffee
Use 1 gram of coffee per 15 grams of water (1:15 ratio). For a standard 34oz (1 liter) press, that's about 60-65 grams of coffee. Using a digital coffee scale ensures consistency.
Grind Coarse
The grind should resemble coarse sea salt or breadcrumbs. Too fine and you'll get bitter, muddy coffee. A burr grinder like the OXO Brew Conical Burr Grinder produces consistent results.
Add Water (The Bloom)
Heat water to 195-205°F (90-96°C). Pour just enough to saturate the grounds and wait 30 seconds. This "bloom" releases CO2 and prepares the coffee for extraction.
Pour and Steep
Add the remaining water in a circular motion. Place the lid on (don't plunge yet) and steep for 4 minutes total.
Plunge Slowly
Press the plunger down slowly and steadily over 20-30 seconds. Rushing creates turbulence that stirs up sediment. If you feel strong resistance, your grind is too fine.
Serve Immediately
Pour all the coffee right away. Leaving it in the press causes over-extraction and bitterness. If you can't drink it all, transfer to a thermal carafe.
Pro Tip: The James Hoffmann Method
World Barista Champion James Hoffmann recommends a modified technique: After 4 minutes, use a spoon to skim off the foam and floating grounds from the top. Then wait another 5-8 minutes before plunging. This produces a cleaner cup with less sediment.
Coffee-to-Water Ratios
The ratio of coffee to water significantly impacts your brew's strength and flavor. Here's a reference table for common French press sizes:
| Press Size | Water | Coffee (1:15) | Coffee (1:12 Strong) | Servings |
|---|---|---|---|---|
| 12 oz (350ml) | 350g | 23g | 29g | 1-2 cups |
| 17 oz (500ml) | 500g | 33g | 42g | 2-3 cups |
| 34 oz (1L) | 1000g | 66g | 83g | 4-5 cups |
| 51 oz (1.5L) | 1500g | 100g | 125g | 6-8 cups |
Understanding Ratios
- 1:15 - Standard strength, balanced flavor (recommended starting point)
- 1:12 - Strong, bold cup for those who prefer intensity
- 1:17 - Lighter brew, good for delicate single-origin coffees

Water Temperature Guide
Water temperature is critical for proper extraction. Too hot and you'll over-extract bitter compounds; too cool and you'll under-extract, resulting in sour, weak coffee.
Optimal: 195-205°F (90-96°C)
The sweet spot for French press. Extracts sugars, oils, and complex flavors without pulling harsh bitter compounds.
Too Hot: Above 205°F (96°C)
Over-extracts bitter tannins. If using boiling water, let it sit 30-60 seconds off the boil.
Too Cool: Below 195°F (90°C)
Under-extracts, producing sour, acidic, and thin coffee. Preheat your press to maintain temperature.
For precise temperature control, a variable temperature kettle lets you dial in the exact temperature. The Fellow Stagg EKG Pro is the gold standard, with precise temperature control and a beautiful gooseneck spout for controlled pouring.
No Thermometer? No Problem
Bring water to a full boil, then let it rest for 30-45 seconds. This typically brings it into the ideal range. At higher altitudes, water boils at lower temperatures, so adjust accordingly.
Grind Size Explained
French press requires a coarse grind - the coarsest setting on most grinders. Here's why it matters:
Correct: Coarse
Resembles coarse sea salt or raw sugar. Individual particles are clearly visible. This allows for proper 4-minute extraction and easy plunging.
Too Fine: Medium/Fine
Over-extracts quickly, producing bitter coffee. Fine particles slip through the mesh filter, creating muddy sediment. Plunger becomes difficult to press.
Grinder Recommendations
A burr grinder produces consistent particle sizes, unlike blade grinders which create uneven "boulders and dust." Here are solid options:
Budget: JavaPresse Manual
This manual burr grinder offers 18 grind settings and ceramic burrs that won't heat up your beans. Perfect for travel or small batches. Takes about 1 minute to grind 30g of beans.
Mid-Range: OXO Brew
The OXO Brew Conical Burr offers 15 settings with micro-adjustments and a hopper that holds 12oz of beans. One-touch operation makes morning grinding effortless.
Value Pick: KRUPS Precision
The KRUPS Precision Burr Grinder delivers 12 grind settings and consistent results at an excellent price point. Great for those just getting into fresh grinding.
Troubleshooting Common Problems
Coffee is Bitter
- Cause: Over-extraction from water too hot, grind too fine, or steep time too long
- Fix: Use cooler water (195°F), coarsen the grind, or reduce steep time to 3:30
Coffee is Sour/Acidic
- Cause: Under-extraction from water too cool, grind too coarse, or steep time too short
- Fix: Use hotter water, fine up the grind slightly, or extend steep to 4:30
Coffee is Weak/Watery
- Cause: Not enough coffee or water cooling during brew
- Fix: Increase dose (try 1:12 ratio), preheat the press, use hotter water
Too Much Sediment
- Cause: Grind too fine, plunging too fast, or worn mesh filter
- Fix: Coarsen grind, plunge slowly (30 seconds), try the Hoffmann method, or replace filter
Plunger Won't Press
- Cause: Grind is too fine, creating resistance
- Fix: Use a coarser grind. If stuck, pull up slightly and try again at an angle
Coffee Gets Cold Too Fast
- Cause: Glass press losing heat, not preheated
- Fix: Always preheat, or upgrade to a double-wall stainless steel press like the Mueller French Press

Frequently Asked Questions
How long should I steep French press coffee?
The standard steep time is 4 minutes. This allows for full extraction without over-extraction. You can adjust slightly based on taste - 3:30 for lighter coffee or up to 4:30 for stronger brews.
Can I use pre-ground coffee?
Yes, but look for "coarse ground" or "French press grind" labels. Pre-ground coffee loses freshness quickly, so buy small quantities and store in an airtight container away from light and heat.
Why does my coffee taste different from a coffee shop?
Coffee shops typically use freshly roasted beans (within 2-4 weeks of roast date), precise measurements, and controlled water temperature. Try buying fresher beans, measuring by weight, and checking your water temperature.
Can I make cold brew in a French press?
Absolutely! Use a 1:8 ratio of coarse coffee to room temperature water. Steep for 12-24 hours in the refrigerator. Plunge and dilute the concentrate with water or milk to taste.
How much caffeine is in French press coffee?
French press coffee typically contains 80-135mg of caffeine per 8oz cup, depending on the coffee and ratio used. This is comparable to drip coffee but can vary based on steep time and coffee-to-water ratio.
Is French press coffee bad for cholesterol?
Unfiltered coffee (including French press) contains cafestol, which can raise LDL cholesterol in some people. If you're concerned, limit consumption to 1-2 cups daily, or use a paper filter over your cup when pouring.
What's the best coffee roast for French press?
Medium to medium-dark roasts work well, as the French press brings out body and oils. Light roasts can taste sour, while very dark roasts may taste bitter. Experiment to find your preference.
