Brew time is the amount of time it takes for water to pass through the coffee grounds and into the cup. In the world of espresso, brew time is a critical factor in determining the flavor, aroma, and overall quality of the shot. In this blog, we will explore the importance of brew time in espresso making and the steps you can take to calculate the correct brew time for your espresso.

Why Brew Time Matters

Brew time is important in espresso making because it affects the extraction time, which in turn affects the flavor and aroma of the shot. If the brew time is too short, the extraction time will be too short, resulting in an under-extracted shot with a sour flavor. If the brew time is too long, the extraction time will be too long, resulting in an over-extracted shot with a bitter flavor.

The Optimal Brew Time for Espresso

The optimal brew time for espresso is between 20-30 seconds. This time frame ensures that the water is in contact with the coffee grounds for the right amount of time to extract the best flavor and aroma from the coffee.

How to Calculate Brew Time for Espresso

To calculate the correct brew time for your espresso, you will need to measure the amount of water that passes through the coffee grounds and into the cup. Here are some steps you can take to calculate the correct brew time for your espresso:

1. Measure the water volume: Use a measuring cup or a scale to measure the water volume that passes through the coffee grounds and into the cup.

2. Time the brew: Use a stopwatch or timer to time the brew from start to finish. Start the timer when you begin brewing the espresso and stop the timer when the desired volume of water has passed through the coffee grounds and into the cup.

3. Calculate the brew time: Divide the water volume by the flow rate to calculate the brew time. For example, if the water volume is 2 ounces and the flow rate is 1 ounce per second, the brew time would be 2 seconds.

4. Adjust as needed: If the brew time is too short or too long, adjust the grind size, tamping pressure, or flow rate to achieve the optimal brew time of 20-30 seconds.

Conclusion

Brew time is a critical factor in the espresso-making process, and the correct brew time is essential for achieving the perfect shot. By measuring the water volume, timing the brew, and adjusting as needed, you can ensure that the water is in contact with the coffee grounds for the right amount of time to extract the best flavor and aroma from the coffee. With a little practice, you will be able to calculate the correct brew time for your espresso every time.
