Quick answerYes. A cup of coffee is about 98% water, so off-tastes like chlorine or heavy minerals come straight through. Use fresh, filtered water with a moderate mineral content. Avoid distilled water (flat taste) and very hard water (dull flavor and scale buildup).
What good coffee water looks like
- Clean, odor-free and clear
- Moderate minerals; some magnesium and calcium help extract flavor
- No chlorine taste
Easy fixes
- A carbon filter pitcher removes chlorine and odors.
- If your water is very hard, mix filtered water with some bottled spring water.
- Use fresh water each time, not water that sat in the kettle overnight.
Protect your equipment
Hard water leaves scale in kettles and coffee makers. Descale monthly to keep temperature and flavor right.
