Step-by-Step Instructions

• 1. First, let’s start with the foundation of a perfect shot: precise measurements. I always say, “A gram is a gram, but the right gram is everything.” Make sure you’re using a scale that can measure down to 0.1 grams, and aim for a dose of around 17-20 grams of coffee for a double shot. This will ensure you’re getting the optimal amount of coffee to water, which is crucial for that perfect balance of flavors.
• 2. Next, it’s time to focus on the grind size. Now, I know some people might say, “What’s the big deal about grind size?” But trust me, it’s a game-changer. You want your grind to be consistent, with a texture that’s similar to sand or slightly finer. If it’s too fine, you’ll end up with a shot that’s over-extracted and bitter; if it’s too coarse, it’ll be under-extracted and weak. I like to use a burr grinder to get the job done, as it produces a more consistent grind than a blade grinder.
• 3. Now that we’ve got our coffee and grind size dialed in, it’s time to think about water temperature. This is where a lot of people go wrong, as they don’t realize that the ideal temperature for brewing espresso is between 195°F and 205°F. If the water is too hot, it’ll burn the coffee and extract too many solids, resulting in a shot that’s unbalanced and unpleasant. On the other hand, if the water is too cold, it won’t extract enough, and you’ll be left with a weak and underwhelming shot.
• 4. With our water temperature under control, let’s move on to tamping. This is an often-overlooked step, but it’s essential for getting a consistent shot. You want to use a tamper that’s specifically designed for espresso, and apply about 30 pounds of pressure to compress the coffee grounds evenly. This ensures that the water flows through the coffee at the right rate, extracting all the delicious flavors and oils that we’re after.
• 5. Next up, we’ve got the machine itself. Now, I’m not going to get into the specifics of different machines here, but I will say that you want to make sure yours is in good working order and properly calibrated. This means checking the group head temperature, the pump pressure, and the flow rate, among other things. If your machine is off, it’ll be impossible to get a good shot, no matter how well you’ve prepared the coffee and water.
• 6. Now we’re ready to pull the shot. This is the moment of truth, where all our hard work comes together. Place a demitasse cup under the spout, and make sure the machine is set to the right dose and brewing time. Then, simply press the button and let the machine do its magic. You should start to see the espresso flow into the cup, with a thick, creamy crema forming on top. This is where the magic happens, and all our careful preparation pays off.
• 7. Finally, it’s time to taste and adjust. This is the final step in our journey to the perfect shot, and it’s where we get to experience the fruits of our labor. Take a sip of the espresso, and pay attention to the flavors and textures that you’re experiencing. Is it balanced and smooth, or is it bitter and over-extracted? Make a note of what you taste, and use that information to adjust your technique for the next shot. Remember, the pursuit of the god shot is a lifelong journey, and there’s always room for improvement.
