You must adjust your grind finer if your shot time is under 25 seconds. You must coarsen your grind if your shot takes well over 30 seconds. Remember, we need our 1:1.5 ratio to pull in 30 seconds. Once you reach your yield, stop the shot and note the time. Place Your scale and cup on the drip tray, then start your shot and timer. Insert your portafilter into the group and tighten it into place until it feels snug and tight, but don’t overtighten. Flush some water through the group head to guarantee it is hot and clean. No matter which machine you use, ensure it is warmed up and ready to go. We can pull a shot now that our coffee bed is leveled and tamped. The amount of pressure is less critical than repeatability and consistency. Lightly lean into the tamp, applying slow and gentle pressure. Your arm should be at about a 90-degree angle. Stand perpendicular to the portafilter and place your tamper into the basket. Hold your tamper between your index finger and thumb, almost like grabbing a doorknob. Keep this to a minimum, as you don’t want to cause a crack in the coffee bed. Once you grind your dose into your portafilter, gently tap the sides of the portafilter a few times to distribute the coffee until it appears flat. To pull an even shot, you need a level coffee bed. As coffee ages, your shots will pull faster, encouraging you to grind finer. You’ll most likely need to change your grind daily too. Changing your grind will allow you to fine-tune the time of your shot. The water will make its way through the rocks much more quicker. Think of coarse coffee like stones and fine coffee like sand. We’ll manipulate the grind size to change how long water flows through the coffee bed. To make this happen, look to your grinder. Aim for your shot to pull between 25 and 30 seconds. Time ties everything together - the total number of seconds a shot takes. The brew ratio we’ll follow today is 20g of ground coffee to 30g of liquid espresso. Ratios for espresso typically range from 1:1 to 1:3, with a general rule of using smaller ratios for darker roasts and larger ratios for lighter roasts. You’ll often see dose and yield written as a ratio - this formula measures ground coffee input to liquid espresso output. Fresh coffee will have lots of crema and weigh less than a shot using older beans. The volume of a shot changes based on the coffee used and when it is roasted. We always recommend weighing coffee in grams, not measuring by volume. Once your dose is set, you’ll choose your yield- this is going to be the total weight, in grams, of your shot of espresso. To ensure your dose is accurate, tare the scale with the portafilter on top, grind it into the basket, and then place the portafilter back on the scale. Always grind into a clean and dry basket. Use a dose between 7-10g of ground coffee for single baskets, 16-18g for double baskets, and 20-22g for triple baskets. Choose your dose based on the basket in your portafilter. Our dose is how much ground coffee we are putting into our basket. Using a scale and measuring these elements in a recipe will help you replicate a great shot and quickly troubleshoot when issues arise. You'll thank us later.Īn espresso recipe consists of dose, yield, and time. What's the difference between dose and yield? What size dose should you be using based on your basket? Grab a pen and notebook, and stop head-scratching whenever your espresso turns out differently. We lay it out in this easy, six-minute step-by-step walkthrough with tips, tricks, and even our signature espresso recipe. Finally, an all-in-one guide to help you master that elusive perfect espresso shot at home.
