Add More Coffee Calculators
Start from the espresso you already pulled and get the hot water to add. The default is 34 g of espresso at 1:2, which is 68 g of water and a 102 g drink. 1:2 makes a stronger cup, not the large Americano common at everyday cafes.
An Americano is espresso with hot water added. A 1:2 split means one part espresso beverage to two parts water. The default is 34 g of espresso and 68 g of water, a 102 g drink.
1:2 makes a stronger cup, not the large Americano common at everyday cafes. There is no single rule for how much water to add.
If you already pulled the shot, keep “I have espresso” selected. If you already decided how much hot water to pour, switch to “I have hot water” and work backward. 1:2 is stronger, 1:6 is common in cafes, and 1:10 is more dilute. A larger number on the right means more added water and a more dilute drink.
For water, 1 g is about 1 ml. Use the weight of the brewed espresso in this calculator, rather than the dry coffee dose.
Perfect Daily Grind reports 1:2 as a slightly milder cup, and cafe drinks that may run as far as 1:15. Hámori’s example is 34 g espresso to 68 g water. Another shop uses 40 g espresso with 250 ml water. The calculator uses the first example as its default: 34 g of espresso with 68 g of hot water, a 1:2 ratio.
To estimate caffeine, use the cup caffeine calculator. Adding hot water dilutes the finished espresso without extracting more from the grounds.
This page does not factor in temperature, pour order, or whether crema stays on top. In Hámori’s example the water is about 75°C. The result gives a dilution ratio; tasting determines whether it suits your preferences.
No. 1:2 makes a stronger cup, not the large Americano common at everyday cafes. Shops often add more water.
That is Tibor Hámori’s double-espresso example in the Perfect Daily Grind piece—34 g espresso to 68 g hot water. Enter the beverage weight you actually pulled, not the dry dose.
It is one dilution ratio commonly used in cafes. The same article cites 40 g espresso with 250 ml water, which sits around 1:6. The amount of water varies with the intended serving size.
A more dilute cup. The same article notes cafe ratios as high as 1:15. It uses more water than 1:6.
Both use espresso and water, but pour order and water volume often differ. This calculator converts weights without assessing pour order or crema retention. See the Americano page for details.
This calculator uses grams. At home, 1 g of water is about 1 ml.
