If your coffee is coming out bitter, weak, or sour, it’s usually not “bad beans.” It’s almost always one (or more) of these four controls: ratio, grind, water temperature, and brew time. Fix those, and your cup changes fast.
If you’re used to spending $6–$8 on a drive-thru cup, this guide shows you how to get a cleaner, stronger cup at home without turning it into a hobby. (If you want the “home vs drive-thru” breakdown, read: drive-thru coffee vs brewing at home.)
The no-guesswork starter recipe (use this first)
If you do nothing else, start here. This hits a balanced strength for most people and gives you a clean baseline to adjust.
Baseline recipe (works great for drip and pour-over)
- Ratio: 1:16 (coffee : water)
- Example: 20g coffee + 320g water (about 11 oz)
- Grind: medium (like sand / table salt)
- Water temp: 195–205°F (90–96°C)
- Total brew time: ~3:00–4:30 depending on method
Want it stronger? Move to 1:15. Too strong? Move to 1:17.
Picking the right beans (without overthinking)
The simplest way to stop wasting money: buy coffee you actually like black before you start “fixing” it with sugar and syrup. If you’re curious why cheap coffee often “needs” sugar, read: why cheap coffee needs sugar and good coffee doesn’t.
Quick selection rules
- For smooth daily cups: start with a medium roast you can drink black.
- For bold, heavier body: go medium-dark or a darker espresso-style roast.
- For “bright”/fruit notes: lean lighter, and brew a little cooler / faster.
If you want a straightforward “works in everything” brew, try a dependable medium-dark like General Quarters. If you’re building strong shots or moka pot cups, an espresso roast like Anchor Espresso is a solid place to start.

Grind size: the fastest way to change taste
Grind controls extraction speed. Too fine = over-extraction (bitter/dry). Too coarse = under-extraction (sour/weak). If you only upgrade one tool, make it a burr grinder.
| Brew method | Grind size | What you’ll notice if wrong |
|---|---|---|
| Drip machine | Medium | Too fine = bitter; too coarse = thin |
| Pour-over | Medium-fine | Too fine = stalls; too coarse = sour |
| French press | Coarse | Too fine = muddy/silty cup |
| Cold brew | Coarse | Too fine = harsh + gritty |
| Moka pot | Medium-fine (not espresso fine) | Too fine = bitter + slow choke |

Water temperature: where “smooth” or “harsh” gets decided
Most balanced cups land in 195–205°F (90–96°C). Below that, you risk sour/under-extracted coffee. Above that, it’s easier to pull harsh bitterness.
| Temp range | What it tends to taste like |
|---|---|
| < 195°F (< 90°C) | Under-extracted (sour, hollow, “watery”) |
| 195–205°F (90–96°C) | Balanced extraction (sweetness shows up) |
| > 205°F (> 96°C) | Over-extraction risk (bitter, dry finish) |
If your tap water tastes like chlorine, your coffee will too. Filtered water is an easy upgrade.

Brew method recipes (pick your lane)
1) Drip machine (most common)
- Ratio: 1:16 (60g coffee per 1 liter water)
- Grind: medium
- Tip: pre-wet paper filter to remove paper taste
- Tip: don’t let brewed coffee sit on a hot plate for 30+ minutes
2) Pour-over (cleanest flavor)
Full walkthrough here: how to brew pour-over coffee.
- Heat water to 195–205°F (90–96°C).
- Use 20g coffee ground medium-fine.
- Rinse filter, add grounds, start timer.
- Bloom: pour ~50g water for 30–45 seconds.
- Pour slowly in circles until you hit 320g total water.
- Total time target: 3:00–3:45. If it runs 5:00+, grind coarser.
3) French press (big body, easy)
If your French press always tastes muddy or harsh, use this: best French press (done right). You can also follow: how to make French press coffee.
- Ratio: 1:15 (e.g., 30g coffee + 450g water)
- Grind: coarse
- Steep: 4:00 minutes
- Pro move: after steeping, stir once, let grounds settle 1 minute, then press gently
4) Cold brew (low acid, smooth)
Guide: how to brew cold brew coffee.
- Start: 1:8 for concentrate (100g coffee + 800g water)
- Grind: coarse
- Steep: 12–16 hours in the fridge
- Serve: dilute 1:1 with water or milk, adjust to taste
5) Moka pot (strong stovetop cups)
Guide: Italian moka pot guide.
- Use hot water in the base (not cold).
- Fill basket level—do not tamp.
- Medium-low heat. Pull it before it sputters aggressively.
If you want a simple “brewable across methods” roast, start with your all roasts collection and pick based on your taste. If you want the strongest lane (moka/espresso style), an espresso roast like Anchor Espresso is built for it.
Quick troubleshooting (fix the cup you made today)
If it tastes bitter / harsh
- Grind a little coarser OR shorten brew time
- Lower water temp toward 195–200°F
- Use slightly less coffee (move from 1:15 to 1:16–1:17)
Deeper breakdown: what makes coffee taste bitter.
If it tastes sour / thin
- Grind a little finer OR extend brew time
- Raise water temp toward 200–205°F
- Use slightly more coffee (move from 1:17 to 1:16)
If you’re using old grocery store coffee, it may never taste “alive.” Compare: roasted-to-order vs grocery store coffee.
FAQs
What’s the best coffee-to-water ratio?
Start at 1:16. If you want stronger, go to 1:15. If it’s too strong, go to 1:17. Use grams if possible—tablespoons vary too much.
What water temperature should I use?
Aim for 195–205°F (90–96°C). Cooler trends sour/under-extracted; hotter trends bitter/over-extracted.
Why does my coffee taste bitter even with “good beans”?
Most bitterness is process: grind too fine, water too hot, brew too long, or a dirty grinder. Start by grinding coarser and checking temp, then clean your grinder: how to clean a coffee grinder.
What grind size should I use?
Drip: medium. Pour-over: medium-fine. French press/cold brew: coarse. Moka pot: medium-fine (not espresso fine). If your brew time is way off target, adjust grind first.
What’s the easiest brew method to start with?
Drip machine or French press. They’re forgiving and consistent. If you want the cleanest flavor, learn pour-over: pour-over guide.
