The least expensive way onto the SCA list — the listing itself carries the Golden Cup award. Glass carafe, 12-cup, bloom function.
Check price on Amazon →The short answer: use about 10 g of coffee (2 level tablespoons) for every 6 oz of water. For a full 12-cup pot the honest answer depends on your machine: about 98 g if its cups are 5 oz, or about 117 g if they are 6 oz. That difference is the whole reason this page exists — a coffee maker's "cup" is not a measuring cup, and once you know which one yours uses, every pot gets more consistent.
The quick answer
For a standard 6 oz coffee-maker cup, start with about 10 g of coffee to 177 ml of water. For an 8 oz mug, use about 13 g. For a 12-cup pot, about 98 g (5 oz cups) or 117 g (6 oz cups). All of these follow the SCA Golden Cup starting point of 55 g of coffee per litre of water, approximately a 1:18 ratio by weight.

How much coffee grounds per cup: tablespoons, scoops and grams
The quick table, at the SCA Golden Cup ratio of 55 g per litre. A level tablespoon of medium-ground coffee weighs about 5 g and a standard coffee scoop holds two tablespoons, so the tablespoon and scoop columns are rounded from the gram column; weigh if you can, because bean density and grind size change what a spoon holds.
| Brewing | Water | Coffee grounds | Tablespoons | Scoops |
|---|---|---|---|---|
| 1 carafe cup (6 oz) | 177 ml | about 10 g | 2 level tbsp | 1 |
| 1 mug (8 oz) | 237 ml | about 13 g | 2½–3 tbsp | 1¼ |
| 4 cups (6 oz) | 710 ml | about 39 g | 8 tbsp | 4 |
| 8 cups (6 oz) | 1.42 L | about 78 g | 16 tbsp | 8 |
| 12 cups (5 oz carafe) | 1.77 L | about 98 g | 20 tbsp | 10 |
| 12 cups (6 oz carafe) | 2.13 L | about 117 g | 23 tbsp | 12 |
How many tablespoons of coffee grounds per cup, then: two level tablespoons for a 6 oz carafe cup, about three for an 8 oz mug. How much coffee grounds for 12 cups: about 98 g if your carafe uses 5 oz cups and about 117 g if it uses 6 oz, which is the difference the next section explains. Any other batch size goes into the calculator below.
The coffee ratio calculator
Enter how much coffee you want to brew. The calculator uses the Specialty Coffee Association's Golden Cup ratio of 55 g per litre by default, and lets you shift stronger or lighter to taste. It supports drip, pour-over, French press and cold brew; AeroPress and espresso ratios are in the brew-method table below, since both are recipe-driven rather than batch-dosed.
How much coffee do I need?
Supported methods: drip · pour-over · French press · cold brew concentrate
The SCA Golden Cup option computes from 55 g per litre, the published figure.
117 g
about 23 tbsp or 12 scoops (approximate) · with 2.13 L (72 oz) of water
Grind: medium, like table salt. Contact time around 4–6 minutes.
Choosing a brew method loads that method's common starting ratio — you can still change it. Cold brew ratios are much stronger because the result is a concentrate you dilute before drinking.
Why your coffee maker's "cup" isn't a measuring cup
Here is a common source of confusion in home brewing. A US customary cup is 8 fluid ounces. A "cup" on your coffee maker is not. Coffee makers commonly use a "cup" smaller than the 8 oz measuring cup: 5 oz is especially common — Braun, for example, documents a 12-cup/60-oz carafe — while other brewers use 6 oz or another volume entirely.
That means a "12-cup" coffee maker holds roughly 60–72 oz of water (about 1.8–2.1 litres) depending on which convention it uses, not 96 oz. If you have been dosing 12 mugs' worth of coffee into it, you have been brewing something closer to syrup — and if you have been dosing by the mug and wondering why it tastes weak, the same arithmetic explains it in reverse.
Check yours once: fill the carafe to its "4 cup" mark, then pour that water into a measuring jug. If it reads about 24 oz, your maker uses 6 oz cups. If it reads about 20 oz, it uses 5 oz cups. Write the answer on a sticky note under the machine and never think about it again.
Sources: manufacturer carafe documentation — Braun specifies 5 fl oz per cup (10-cup/50 oz, 12-cup/60 oz, 14-cup/70 oz), and other brands mark 5 or 6 oz — corroborated by Fresh Roasted Coffee's measurement guide and JES Restaurant Equipment's carafe sizing explainer.
The Golden Cup standard, explained
The Specialty Coffee Association maintains the closest thing filter coffee has to an official brewing benchmark: the Golden Cup standard. It is worth knowing because it is the reference point most published brewing guidance is measured against — though plenty of brewing traditions predate it and operate happily outside it.
| Parameter | SCA Golden Cup specification | What it means in practice |
|---|---|---|
| Coffee dose | 55 g per litre of water, ±10% | Roughly a 1:18 ratio by weight — about 10 g per 6 oz cup |
| Water temperature | 200°F ±5°F (93°C ±3°C) at contact | Just off the boil. Higher temperatures generally increase extraction, lower temperatures reduce it |
| Extraction yield | 18–22% of the coffee's mass dissolved | Below 18% is generally associated with under-extraction, above 22% with over-extraction. Flavour is not determined by extraction yield alone |
| Brew strength (TDS) | 1.15–1.35% total dissolved solids | The concentration in the cup — what most people call "strength" |
| Contact time | Varies by grind and device: roughly 1–4 min (fine), 4–6 min (drip/medium), 6–8 min (coarse) | There is no single contact-time figure — the specification differentiates by grind. Brewers carrying SCA certification are tested against specified brewing-performance requirements; ordinary home machines vary in temperature, flow and contact time |
Two of these are worth internalising. The coffee-to-water ratio strongly influences beverage strength — how concentrated the finished cup is. The extraction yield describes how much of the coffee's soluble material actually dissolved, which is what most flavour faults track. They are related but not interchangeable: you can brew a weak-but-bitter cup or a strong-but-sour one, which is why "add more coffee" is not always the fix.
Primary source: the Specialty Coffee Association's Golden Cup specification. Additional references reproducing the same figures: Moccamaster's certification documentation and Ratio's SCA certification announcement. The 55 g/L figure and the 18–22% extraction window are consistent across all three. Contact time in the standard is differentiated by grind rather than given as a single range, and is stated that way above. Note that 55 g/L is the published figure; "1:18" is the convenient rounded shorthand for it (55 g/L is exactly 1:18.18), and this page's calculator computes from 55 g/L rather than from the rounded ratio.

By carafe "cups" (6 oz each) at the Golden Cup ratio
| Carafe cups | Water | Coffee (grams) | Tablespoons | Scoops |
|---|---|---|---|---|
| 1 | 6 oz / 177 ml | 9.8 g | 2 | 1 |
| 2 | 12 oz / 355 ml | 20 g | 4 | 2 |
| 4 | 24 oz / 710 ml | 39 g | 8 | 4 |
| 6 | 36 oz / 1.06 L | 59 g | 12 | 6 |
| 8 | 48 oz / 1.42 L | 78 g | 16 | 8 |
| 10 | 60 oz / 1.77 L | 98 g | 20 | 10 |
| 12 | 72 oz / 2.13 L | 117 g | 23 | 12 |
Careful with "12 cups": the row above assumes 6 oz cups, giving 72 oz. Many 12-cup makers are actually 60 oz (5 oz cups) — in that case use about 98 g. This is exactly why checking your carafe once is worth the two minutes.
By mug (8 oz each)
| Mugs | Water | Coffee (grams) | Tablespoons |
|---|---|---|---|
| 1 | 8 oz / 237 ml | 13 g | 2.6 |
| 2 | 16 oz / 473 ml | 26 g | 5.2 |
| 4 | 32 oz / 946 ml | 52 g | 10 |
Conversions used throughout: 1 fl oz = 29.57 ml; SCA ratio 55 g/L; 1 level tablespoon of medium-ground coffee ≈ 5 g; 1 standard coffee scoop = 2 tablespoons ≈ 10 g. Tablespoon and scoop weights are approximations — bean density and grind size change them, which is the case for using a scale.
Ratios by brew method
The Golden Cup ratio is a published filter-coffee standard. Everything in the table below is different in kind: these are common starting ranges drawn from widespread practice and recipe convention, not standards issued by any body. Treat them as places to begin, then adjust to taste.
| Method | Common starting ratio | Grind | Notes |
|---|---|---|---|
| Drip / filter machine | 1:16 – 1:18 | Medium | Brewers carrying SCA certification are tested against specified brewing-performance requirements; ordinary home machines vary in temperature, flow and contact time. |
| Pour-over | 1:15 – 1:17 | Medium-fine | You control the pour, so brew time varies; aim for 2:30–4:00 total. |
| French press | 1:12 – 1:15 | Coarse | No paper filter means more body; 4 minutes then plunge. |
| AeroPress | 1:12 – 1:16 | Fine-medium | Hugely variable by recipe — a strong starting point is 15 g to 200 ml. |
| Cold brew concentrate | 1:5 – 1:8 | Coarse | Steep 12–18 hours. A common starting dilution is roughly 1:1 with water or milk, then adjust to taste — our cold brew maker picks cover the vessel side. |
| Espresso | 1:2 (brew ratio) | Very fine | A different discipline. A common starting recipe is ~18 g in, ~36 g out, in 25–32 seconds. See our espresso grinder guide. |
The gear that makes ratios repeatable
Brewers the SCA has actually certified
The Golden Cup figures above describe a brewing target. A certified brewer is one the SCA has independently tested against its brewing-performance requirements — which matters, because an ordinary drip machine can miss the temperature window entirely. These four are on the SCA's current Certified Home Brewer list, which we read directly from sca.coffee on 27 August 2026, with the certification year the SCA publishes for each.

It does not appear on the SCA's certified-equipment list as published at the time we checked (27 August 2026), and neither does Bonavita. That is not a verdict on either machine — plenty of excellent brewers have never entered the programme, and certifications lapse or are not renewed. It only means the certification claim itself should not be relied on without checking the SCA's current list.

Fixing bitter and sour coffee
Before you change the ratio, work out which direction the cup is off. These are heuristics, not diagnoses — bitterness and sourness each have several possible causes, including roast level, water chemistry, coffee age, and simple concentration — but as starting points they resolve most everyday problems, and the two directions have opposite fixes.
| Symptom | Likely cause | Fix, in order |
|---|---|---|
| Bitter, harsh, drying | Can be a sign of over-extraction; may also reflect dark roast, very high concentration, or water chemistry | Coarsen the grind → shorten brew time → lower water temp slightly |
| Sour, thin, salty | Can be a sign of under-extraction; may also reflect a very light roast or under-dosing | Fine the grind → lengthen brew time → make sure water is hot enough |
| Weak but not sour | Correct extraction, low ratio | Add coffee (move from 1:18 toward 1:15) |
| Strong but muddy | The ratio may be fine — excessive fines, agitation, sediment or over-extraction can all contribute | Check grind consistency and filtration before changing the ratio |
A useful troubleshooting order: grind first, ratio second. Our grind size chart covers what each brewing method wants. Coffee-to-water ratio primarily influences how strong the finished cup is; grind size and contact time strongly influence how much of the coffee actually dissolves, so when a cup tastes distinctly under- or over-extracted those are the variables to move first. Grind and time are also coupled — coarsening the grind usually changes how fast the water passes through — so change one thing at a time. If your grind is inconsistent, none of this is adjustable in the first place, which is why a burr grinder is the foundational upgrade; our Best Overall Burr Grinder award covers the evidence-led pick.
Frequently asked questions
How much coffee grounds per cup?
For one 6 oz "coffee maker cup" (177 ml), use about 10 g of coffee — roughly 2 level tablespoons. For a full 8 oz mug (237 ml), use about 13 g. Both figures follow the Specialty Coffee Association's Golden Cup standard of 55 g of coffee per litre of water (±10%), which works out to approximately a 1:18 coffee-to-water ratio by weight.
How many scoops of coffee per cup?
One level standard coffee scoop holds about 2 tablespoons, which is roughly 10 g of ground coffee — so about one scoop per 6 oz carafe cup. An 8 oz mug needs about 13 g, which is roughly 2½ to 3 level tablespoons, or about 1¼ scoops. Because scoop capacity and coffee density both vary, these volume measures are starting points rather than precise doses: a basic kitchen scale is the simplest way to make your dose repeatable.
How much coffee for 12 cups?
It depends on what your machine calls a cup, and this is a common brewing mistake. If your carafe uses 5 oz cups, a 12-cup pot holds 60 oz (1.8 litres) and needs about 98 g of coffee at the SCA Golden Cup ratio — call it 100 g, or 10 level scoops. If it uses 6 oz cups, the pot holds 72 oz (2.1 litres) and needs about 117 g, roughly 12 scoops. Check your carafe markings against a measuring jug once and you will never have to wonder again.
What is the golden ratio for coffee?
The Specialty Coffee Association's Golden Cup standard specifies 55 g of coffee per litre of water, ±10% — approximately 1:18 by weight — brewed with water at 200°F ±5°F (93°C ±3°C), targeting an extraction yield of 18–22% and a brew strength of 1.15–1.35% total dissolved solids. Many home recipes use ratios in this general range, though taste, brewer design and the coffee itself all affect the best starting point.
Should I measure coffee by weight or by volume?
By weight, if you can. A tablespoon of dense, dark-roasted beans and a tablespoon of light-roasted beans can differ by several grams, and grind size changes how much fits in the same volume too — so the same "2 scoops" can contain noticeably different amounts of coffee. A basic kitchen scale removes that variable entirely and is one of the simplest ways to make your dose repeatable.
Why does my coffee taste bitter or sour?
Bitterness can be a sign of over-extraction — too much coffee surface exposed for too long (grind too fine, brew too long, or water too hot). Sourness can be a sign of under-extraction — grind too coarse, brew too short, or water too cool. Both have other possible causes, including roast level, coffee age and water chemistry. A useful troubleshooting order is grind first, then ratio, then time, keeping water in the 195–205°F range the SCA specification gives.
