What is the perfect espresso shot?
The brew ratio we’ll follow today is 20g of ground coffee to 30g of liquid espresso. Time ties everything together – the total number of seconds a shot takes. Aim for your shot to pull between 25 and 30 seconds. To make this happen, look to your grinder. The 30-second extraction rule suggests that a well-balanced espresso shot should take approximately 25-30 seconds to extract when using 18-20 grams of ground coffee and yielding about 30-40 milliliters of espresso.Serving Size. Most standard espresso cups are designed so that they can serve a single shot of espresso with an average serving size of 30ml, and double shot of espresso, with an average serving size of 60ml.A traditional espresso is typically 1:2-1:2. It’s important to remember that these ratios aren’t hard rules, and are more like guidelines. In general, you should dial-in your espresso to ensure that your taste and mouthfeel is as you want it.Espresso is defined at around 9 bars of pressure. Some machines advertise 15–20 bar pumps, but that figure refers to maximum pump output, not the pressure used for brewing. The best espresso comes from a stable 9 bar; anything higher doesn’t improve flavour.
What is the golden rule of espresso?
The Espresso Golden Ratio The golden ratio for espresso brewing is typically a 1:2 to 1:2. For example, we should aim to extract 36g of liquid espresso from the 18g of ground coffee in 30 seconds, giving us our target ratio of 1:2. Don’t be afraid to try different coffees or big changes in your ratio style, but when you find a coffee you like, stick with it for some time!
