# Coffee too strong or heavy? How to lighten it

> Heavy or overpowering coffee is too concentrated: too much coffee dissolved into too little water. Change one thing per brew, in this order: Use a little less coffee, then add bypass water, then use more brew water.

## What it means

A cup that's heavy, syrupy or coats your mouth is too strong: too much coffee dissolved into too little water. It's the opposite of watery, and it's fixed the same way — through the ratio rather than the grind.

Use a little less coffee, dilute the finished brew, or lengthen the ratio. Each keeps the extraction you've already found and just changes how concentrated it is.

## Pour over: what to change

Pour over (V60, Chemex, Kalita Wave, Origami, Orea). Try these one at a time, in this order.

1. **Use a little less coffee** — About 6% less — 1g off a 16g brew — at the same water. A weaker ratio and a shallower bed.
2. **Add bypass water** — Dilute the finished brew with extra water — about 10% of the brew water, added after. Strength drops without touching extraction.
3. **Use more brew water** — About 10% more water for the same dose — a longer ratio and a lighter cup.
4. **Lower your water's mineral content** — About 20% fewer minerals — 150 to 120 ppm, say. Softer water extracts more gently, and with less buffering on the acidity it reads cleaner and brighter.
5. **Try a brighter water profile** — Last resort. A new water changes several flavours at once, which makes it hard to tell what did what — so it comes after every single-variable change has had its go.

## Immersion: what to change

Immersion (AeroPress, French Press, Hario Switch). Try these one at a time, in this order.

1. **Use a little less coffee** — About 6% less — 1g off a 16g brew — at the same water. A weaker ratio and a shallower bed.
2. **Add bypass water** — Dilute the finished brew with extra water — about 10% of the brew water, added after. Strength drops without touching extraction.
3. **Use more brew water** — About 10% more water for the same dose — a longer ratio and a lighter cup.
4. **Lower your water's mineral content** — About 20% fewer minerals — 150 to 120 ppm, say. Softer water extracts more gently, and with less buffering on the acidity it reads cleaner and brighter.
5. **Try a brighter water profile** — Last resort. A new water changes several flavours at once, which makes it hard to tell what did what — so it comes after every single-variable change has had its go.

## Cold brew: what to change

Cold brew. Try these one at a time, in this order.

1. **Use a little less coffee** — About 6% less — 1g off a 16g brew — at the same water. A weaker ratio and a shallower bed.
2. **Add bypass water** — Dilute the finished brew with extra water — about 10% of the brew water, added after. Strength drops without touching extraction.
3. **Use more brew water** — About 10% more water for the same dose — a longer ratio and a lighter cup.
4. **Lower your water's mineral content** — About 20% fewer minerals — 150 to 120 ppm, say. Softer water extracts more gently, and with less buffering on the acidity it reads cleaner and brighter.
5. **Try a brighter water profile** — Last resort. A new water changes several flavours at once, which makes it hard to tell what did what — so it comes after every single-variable change has had its go.

## Change one thing at a time

It's tempting to grind finer *and* raise the temperature *and* pour differently. Then the next cup is better or worse and you don't know why. One change per brew is slower on paper and much faster in practice. The [full dial-in guide](https://cuplift.app/dial-in) covers the order to fix things in when there's more than one problem.

## Questions

### Why is my coffee too strong?

Heavy or overpowering coffee is too concentrated: too much coffee dissolved into too little water. A cup that's heavy, syrupy or coats your mouth is too strong: too much coffee dissolved into too little water. It's the opposite of watery, and it's fixed the same way — through the ratio rather than the grind.

### How do I make my coffee less strong?

Change one thing per brew. On a pour over: Use a little less coffee, then add bypass water, then use more brew water. On an AeroPress, French Press or Hario Switch: Use a little less coffee, then add bypass water, then use more brew water.
