18 g coffee × 2 = 36 g espresso

This ratio compares dry coffee with espresso output, not brewing water.

A balanced latte starts here with 36 g espresso and 170 g milk.

Your cup doesn’t need to be full. Keep the balance you enjoy.

18 g coffee

Measure your starting dose.

Weigh 18 g of dry ground coffee in a basket suitable for that dose. Keep the input consistent before changing other variables.

Two ratios.
One important difference.

Espresso yield = coffee dose × brew ratio. For example, 18 g coffee at 1:2 gives a target of 36 g espresso. Milk or water added afterwards shapes the finished drink.

A coffee-to-water ratio calculator for drip or pour over uses brewing water instead of shot yield. At an example 1:16 coffee grounds to water ratio, 240 g water calls for 15 g coffee.

How this coffee calculator works ↓

With a 36 g shot, this tool starts with 170 g milk for a latte, 90 g for a flat white or cappuccino, 36 g for a cortado, or 108 g water for an Americano. These are adjustable examples, not universal café definitions. The balance slider changes the addition by up to 20% in either direction.

Recipes scale with espresso yield and are capped by cup capacity, allowing 10% headroom or 25% for cappuccino. For this rough fit estimate only, liquid weight is approximated as volume. Foam, crema and pitcher technique affect the actual result. A larger cup does not automatically need more milk.

Coffee ratio calculator FAQ

How much milk should I add to a double espresso?

For this tool’s 36 g espresso starting recipes, try 36 g milk for a cortado, 90 g for a flat white or cappuccino, or 170 g for a latte. These are adjustable suggestions. Texture, cup size and personal taste affect the result.

Is the milk amount measured before or after steaming?

The result is the approximate weight of milk to add to your cup, excluding foam. Start with enough cold milk for your pitcher and steam wand, then pour what you need. Extra milk left in the pitcher is not included in the recipe.

Why doesn’t the recipe fill my cup?

Cup capacity is a maximum. The calculator preserves the selected drink’s starting proportions instead of adding milk simply to fill a larger cup. It also allows room for foam and the cup rim.

Can I use a different coffee dose or brew ratio?

Yes. Open “Espresso dose & ratio” to change the dose and brew ratio. Use a dose suitable for your basket; the tool scales milk or water from the target espresso yield.

How many grams of coffee per cup should I use?

For this espresso tool, the default is 18 g ground coffee for a 36 g shot; use a dose that suits your basket. If you mean how much ground coffee per cup of drip or pour-over coffee, first define the brewing water amount and ratio. For example, 240 g water at 1:16 calls for 15 g coffee. The word “cup” alone does not specify a dose.

How many scoops of coffee per cup?

There is no reliable universal scoop count: scoop size, grind and how you fill it change the weight. Weigh one level scoop of your own grounds, then divide the target dose by that weight. If your scoop holds 5 g and the recipe needs 15 g, use three level scoops. For espresso, weighing the dose is easier to repeat.

What coffee proportions work for drip and pour over?

Drip coffee proportions and a pour over coffee ratio compare dry grounds with brewing water, not finished coffee. As a calculation example, 1:16 means 1 g coffee for every 16 g water. Select a recipe suited to your brewer, then adjust by taste. Use a coffee-to-water ratio calculator to scale that recipe; do not apply this page’s 1:2 espresso example to a drip brewer.

How much coffee for 12 cups?

Check the water volume marked on your brewer before calculating: a machine’s “cup” may differ from your drinking cup. If a 12-cup batch uses 1,800 g water and your chosen recipe is 1:16, use 1,800 ÷ 16 = 112.5 g ground coffee. That is an example based on an assumed capacity, not a universal dose for every 12-cup machine.

Can I use this as a cold brew coffee calculator?

This tool builds espresso drinks. A cold brew coffee ratio instead compares grounds with steeping water; a concentrate also has a separate serving dilution. A dedicated cold brew coffee calculator should distinguish concentrate from ready-to-drink coffee and account for the amount you intend to dilute. Follow your brewer’s recipe rather than substituting an espresso ratio.

Does this include a coffee calorie calculator?

Calories are not calculated here. A coffee calorie calculator needs the amounts and nutrition values of the milk, cream, sugar and syrups you actually use. For an ingredient listed in kcal per 100 g, multiply that value by the grams added and divide by 100, then total the ingredients. If the label uses ml, measure by volume instead; milk type and serving size both matter.
