How to Dial In Espresso: Step-by-Step Guide for Beginners
Introduction to Dialing In Espresso
Dialing in espresso is the process of adjusting the dose, grind, and tamp to achieve the perfect shot. According to the Specialty Coffee Association (SCA), 2020, these three variables are crucial in determining the quality of the espresso. To dial in espresso, one must understand how to adjust these variables to achieve the desired flavor and crema.
The Three Dial-In Variables
The three key variables in dialing in espresso are dose, grind, and tamp. The Specialty Coffee Association (SCA), 2020, recommends a dose of 17-22 grams for a double shot. The grind size and distribution are also critical, as they affect the flow of water through the coffee. The Barista Guild of America, 2019, provides guidelines for adjusting grind size and distribution.
Setting Your Ratio (1:2 Standard)
A standard ratio for espresso is 1:2, meaning one part coffee to two parts water. According to James Hoffmann’s 2020 ratio test, a 1:2 ratio yields a shot time of 25-30 seconds. The Specialty Coffee Association (SCA), 2020, targets an extraction yield of 18-22% for balanced espresso.
Ratio Guide
| Dose (g) | Yield (g) | Ratio |
|---|---|---|
| 17 | 34 | 1:2 |
| 20 | 40 | 1:2 |
| 22 | 44 | 1:2 |
Adjusting Grind Size
Adjusting the grind size is crucial in achieving the perfect shot. The Barista Guild of America, 2019, recommends adjusting the grind size based on the flow of water through the coffee. A finer grind will result in a slower flow, while a coarser grind will result in a faster flow.
Grind Size Adjustment Methods
- Blind adjustment: Adjust the grind size without measuring the flow rate.
- Flow rate adjustment: Measure the flow rate and adjust the grind size accordingly.
Reading the Shot
Reading the shot is critical in determining if the espresso is underextracted (sour) or overextracted (bitter). According to a World Barista Championship judge, 2018, a well-extracted shot will have a balanced flavor and a thick crema.
Shot Characteristics
| Characteristic | Underextracted | Overextracted |
|---|---|---|
| Flavor | Sour | Bitter |
| Crema | Thin | Thick |
| Body | Light | Heavy |

My Take
As an app developer and trained chef, I have always been fascinated by the art of dialing in espresso. I remember my first experience with a Breville Bambino Plus Espresso Machine, and how it changed my perspective on coffee. With its precise temperature control and adjustable grind size, I was able to experiment with different ratios and flavors.
In my daily routine, I use a Breville Bambino Plus Espresso Machine on Amazon to dial in my espresso. I also use a Rancilio Rocky Coffee Grinder on Amazon to grind my beans, and a WDT Distribution Tool on Amazon to evenly distribute the coffee grounds in the portafilter.
