A question thrown out there by many coffee lovers and coffee enthusiasts is how many ounces in a shot of espresso?

Rather than drag such a simple answer out, I’ll give you the quick and simple answer before diving into a more detailed answer throughout this article.

From a coffee purist’s point of view a shot of espresso is one fluid ounce, a double shot is 2 fluid ounces and a triple shot of espresso is 3 fluid ounces.

A single fluid ounce is precisely 30 milliliters while an ounce by weight is 28 grams. It is important to distinguish the difference as we measure an espresso shot volume by the amount of water that is used to brew the shot and not the actual weight of the shot.

Keep reading as we dig down deeper and properly detail the topic of how many ounces are in a shot of espresso and get properly detailed and talk about various espresso drinks and how much coffee grounds are used to pull that shot!

How Many Ounces In A Shot Of Espresso A More Detailed Answer?

While a proper shot of espresso will be a single ounce or 30 ml, it is not uncommon for coffee shops to alter this and use 1.5 ounces as a standard measurement for a single shot while using more coffee grounds to pull their shot in order to maintain their coffee to water ratio.

This, depending on the establishment, will make a double shot 3 ounces and a triple shot of espresso 4.5 ounces.

These are, unfortunately, outwith what is the traditional and exact single ounce measurement set by industry standards.

How Much Coffee Is Used To Make A Shot Of Espresso?

The amount of coffee by weight to be used to make a single shot of espresso is 7 grams of ground coffee to adhere to the perfect coffee to water ratio to make the perfect coffee.

When a coffee shop is using a 1.5 ounce measurement as a standard measurement, 10.5 grams of ground coffee is used for a single espresso shot.

A double shot will have 14 grams of coffee in a double shot in a standard 60 ml two ounce shot and 21 grams in a non-standard 90 ml 3 ounce double shot to maintain that coffee to water ratio.

The ground coffee used must be fresh in order to produce the rich thick crema on top. The standard grind size is 250 microns, which is a very fine powder.

The correct amount of pressure to be used is 9 bars (130 grams) of water pressure to produce a perfect shot of espresso. The water pressure is an important aspect of brewing an espresso as without it, you will not get that thick, rich and tasty crema on top and may result in under or over extracted cups of coffee.

The pressure is measured as the resistance given by the coffee grounds in your portafilter.

The perfect flow rate or brew time is 25 seconds with a variance of plus or minus 5 seconds. Follow these rules for weight of coffee used, brew time, fresh coffee beans and pressure, and you will get the full flavor from your coffee beans into your shot of espresso.
