🫙☕ Why Is My French Press Bitter?

⚡ Quick Answer

Your French press is bitter because it’s over-extracted—usually from grinding too fine, steeping too long, or using water that’s too hot.

🔬 Why It Happens

French press is full immersion, so the coffee sits in water the entire time. That means:

• Too fine a grind → over-extraction
• Steeping too long (past ~4 min) → bitterness increases
• Water too hot → pulls harsh compounds
• Letting coffee sit after plunging → continues extracting

🔧 How to Fix It

• Use a coarse grind (like sea salt)
• Steep for 4 minutes (start here)
• Use water around 200–205°F
• Plunge slowly, then serve immediately (don’t let it sit)

French press rewards control. Go coarser, keep time tight, and don’t let it sit, and your cup will be smooth and rich—not bitter.
