Pour Over Coffee Ratio Chart for Beginners
The ratio of coffee to water is the single biggest variable in your cup. Get it right and everything else becomes easier to troubleshoot. Get it wrong and even great beans and a beautiful dripper won’t save you.
The standard pour-over range is 1:15 to 1:17 — meaning 1 gram of coffee for every 15 to 17 grams of water. If you’re new to this, start at 1:16. It’s forgiving, works with most beans, and gives you a clear baseline to adjust from.
The rest of this guide explains what those numbers mean, gives you a simple recipe to start today, and shows you how to fix a cup that isn’t tasting right.
What Does a Pour Over Coffee Ratio Mean?
A coffee ratio is just the relationship between how much coffee you use and how much water you brew with — both measured in grams.
1:16 means: 1 gram of coffee for every 16 grams of water.
So with 20 grams of coffee, you’d use 320ml of water. (Grams and milliliters are close enough for water that you can use them interchangeably here.)
That’s it. No special math required — just pick a ratio, weigh your coffee, multiply, and you have your water amount.
Pour Over Ratio Chart
Use this chart as a quick reference. All amounts are in grams; water volume in milliliters.
| Coffee (g) | 1:14 Water (ml) | 1:15 Water (ml) | 1:16 Water (ml) | 1:17 Water (ml) |
| 12g | 168ml | 180ml | 192ml | 204ml |
| 15g | 210ml | 225ml | 240ml | 255ml |
| 18g | 252ml | 270ml | 288ml | 306ml |
| 20g | 280ml | 300ml | 320ml | 340ml |
| 25g | 350ml | 375ml | 400ml | 425ml |
| 30g | 420ml | 450ml | 480ml | 510ml |
What each ratio tastes like:
| Ratio | Taste Profile | Best For |
| 1:14 | Bold, strong, full-bodied | If you like a punchy cup |
| 1:15 | Rich, balanced, slightly heavy | Darker roasts, bold coffees |
| 1:16 | Balanced, medium-bodied | Best starting point for beginners |
| 1:17 | Light, delicate, clean | Light roasts, nuanced coffees |
Start here: Brew once at 1:16. If it tastes too strong or bitter, go to 1:17. If it tastes weak or watery, try 1:15. Adjust one step at a time.
Beginner Pour Over Recipe
This recipe uses a 1:16 ratio and works with most standard drippers. It makes roughly one 10–12 oz cup.
What You’ll Need
- Pour-over dripper + carafe or mug
- Paper filter
- Digital scale
- Kettle (gooseneck recommended, but not required)
- Freshly ground coffee, medium-fine grind
Recipe
- Coffee: 20g
- Water: 320ml at 195–205°F (90–96°C)
- Target brew time: 3:00–3:30 minutes total
Steps
- Heat your water. Bring water to about 200°F (93°C). No thermometer? Bring it to a full boil, take it off the heat, and wait 30 seconds.
- Rinse your filter. Place the paper filter in your dripper and pour a small amount of hot water through it. This removes any papery taste and warms the brewer. Discard that water.
- Add your coffee and tare the scale. Add 20g of ground coffee to the filter. Set your scale to zero.
- Bloom (0:00–0:45). Pour 40–50ml of water slowly and evenly over the grounds — just enough to wet them completely. You’ll see the coffee puff up and release gas bubbles. Wait 30–45 seconds before continuing. This lets trapped CO₂ escape so water can move through the grounds more evenly.
- Pour the remaining water (0:45–2:45). Pour the rest of your water in slow, steady circles, keeping the water level consistent. Don’t rush. Try to finish all 320ml by around 2:30–2:45.
- Let it finish dripping. Once you’ve finished pouring, the remaining water will drip through. Your total brew time — from first pour to last drip — should land around 3:00 to 3:30 minutes.
If it drains much faster or slower than that, see the grind size section below.
Grind Size and Ratios Work Together
Getting your ratio right is only half the picture. If your grind size is off, even the right ratio won’t save your cup.
For pour-over, aim for medium-fine — roughly the texture of coarse sand or table salt. Finer than drip coffee, coarser than espresso.
The fastest way to check your grind is by watching your brew time:
| Brew Time | What It Means | Fix |
| Under 2:30 | Grind too coarse — water ran through too fast | Grind finer |
| 3:00–3:30 | You’re in a good range | No change needed |
| Over 4:00 | Grind too fine — water is getting stuck | Grind coarser |
Make grind adjustments in small steps. If your brew time is way off (under 2 minutes or over 5), check your ratio first — it may be a combination of both.
Water Temperature
Water that’s too hot can make your coffee taste harsh and bitter. Water that’s too cool can leave it tasting sour or flat.
The target range for pour-over is 195–205°F (90–96°C).
If you don’t have a thermometer: boil water, remove from heat, and wait 30–45 seconds before pouring. That puts you in the right ballpark for most situations.
A variable-temperature kettle makes this easier — you set a temperature and it holds it. Not necessary to start, but useful if you brew daily.
Troubleshooting a Bad Tasting Pour Over
Coffee Tastes Bitter
Bitterness means your coffee likely over-extracted — the water pulled too much from the grounds. Check these first:
- Ratio too strong — try moving from 1:15 to 1:16 or 1:17
- Grind too fine — coarsen it by one or two steps
- Water too hot — let it cool a few extra seconds before pouring
- Brew time too long — aim to finish pouring before the 2:45 mark
Coffee Tastes Sour or Sharp
Sourness usually means under-extraction — the water moved through too quickly or wasn’t hot enough to pull flavor evenly.
- Ratio too weak — try 1:15 instead of 1:16 or 1:17
- Grind too coarse — go one step finer
- Water not hot enough — aim closer to 200°F
- Skipped or rushed the bloom — a proper 30–45 second bloom makes a real difference here
Coffee Tastes Flat or Watery
This is almost always a ratio or freshness issue.
- Ratio too weak — move from 1:17 to 1:16 or 1:15
- Stale beans — if your coffee has been sitting open for more than two to three weeks, much of the flavor has already off-gassed. Fresh beans make a bigger difference than most people expect.
Common Pour Over Mistakes Beginners Make
Most bad cups trace back to one of these:
Eyeballing instead of measuring.
A coffee scoop is not a unit of measurement — grind size, bean density, and how you fill the scoop all change the amount. A cheap kitchen scale fixes this immediately.
Skipping the bloom.
It looks optional. It isn’t. Skipping it makes extraction uneven, which shows up as sourness or muddiness in the cup.
Changing two things at once.
If you adjust both the ratio and the grind at the same time, you won’t know which one fixed the problem. One change per brew.
Using stale pre-ground coffee.
Ground coffee loses most of its flavor within a week or two of being ground. Whole beans stay fresh much longer. If you can, grind right before you brew.
Pouring too fast.
A slow, steady pour gives you more control over extraction. Dumping water in quickly tends to channel and extract unevenly.
Do You Really Need a Scale?
Not technically. But it helps more than almost anything else you could add to your setup.
Scoops are unreliable. The same “one tablespoon” can hold noticeably different amounts of coffee depending on grind size and how packed the grounds are. A scale makes your ratio repeatable — which means when you find something that tastes good, you can make it again.
A basic digital kitchen scale works fine. It doesn’t have to be a specialty coffee scale. If you want to take it further, a scale with a built-in timer lets you watch both weight and brew time in one place.

You don’t need much to brew good pour-over coffee. Here’s what actually makes a difference, and what to look for if you’re shopping.
Digital Scale
Look for a scale that reads in 0.1g increments. A built-in timer is a nice addition for pour-over since you’re tracking both at once — but it’s not essential. Budget options work fine here.
Gooseneck Kettle
A gooseneck spout gives you much more control over where the water lands and how fast it flows. You can brew pour-over without one, but it’s noticeably harder to pour slowly and evenly with a standard kettle. If you brew pour-over regularly, this is worth it.
Burr Grinder
A burr grinder produces consistent particle sizes. A blade grinder chops unevenly, which makes extraction harder to control. Most hand burr grinders produce more consistent results than blade grinders, making them a worthwhile upgrade even on a tight budget.
Pour Over Dripper
Most beginners do well with a simple cone or flat-bottom dripper. Each style has slightly different flow characteristics, but all of them can make excellent coffee — the ratio and grind matter far more than the specific brewer you choose.
Frequently Asked Questions
Start at 1:16 — 1 gram of coffee for every 16 grams of water. It’s balanced, forgiving, and a good baseline for most beans and drippers.
For a 10–12 oz cup, 18–22 grams of coffee is a reasonable range. Pair that with 280–350ml of water at 1:16 and adjust based on how it tastes.
You can, but the results will be inconsistent. Grind size and bean density change how much fits in a spoon. A kitchen scale gives you repeatable results.
Some brewers adjust slightly by roast level, but this is more of a fine-tuning step once you have your basics dialed in. Start at 1:16 regardless of roast and adjust from taste.
A 1:15 ratio produces a stronger, fuller cup; 1:17 is lighter and more delicate. The difference is real but subtle — taste it for yourself over a few brews.
If your tap water has a strong taste or smell, filtered water can make a noticeable difference in your cup. In areas with good tap water, the impact is more modest.
Good pour over coffee doesn’t require precision obsession. It requires a consistent starting point.
Use 1:16 as your ratio. Grind medium-fine. Brew with water around 200°F. Aim for a 3:00–3:30 minute brew time. Taste it. Adjust one thing at a time. That’s the whole system.
The ratio chart above gives you the numbers — the rest is just practice.
