๐ฌ Why It Happens
Flat coffee lacks aroma and complexity. This usually comes from:
- Stale beans (past peak freshness)
- Coffee ground too far in advance
- Weak or uneven extraction
When aromatics fade, the cup tastes dull and lifeless.
๐ง How to Fix It
- Use fresh beans (ideally 3โ14 days after roast)
- Grind just before brewing
- Adjust extraction (grind slightly finer or brew a bit longer)
- Check your ratio (1:15โ1:17 works well)

๐ฏ Bottom Line
Flat coffee isnโt exciting because itโs lost its life. Use fresh beans and dial in extraction to bring your cup back to life.
