Having watched countless baristas pull shots in your home Drink coffee Lifetime, you would think it wouldn’t be that hard to do at home, right? So why does home-brewed espresso come out runny, with no evidence of crema one day, and thick and bitter the next? It can’t just be owning something expensive No Marzocco The model is truly a barrier to entry when it comes to pulling off a top notch shot.
Nothing can beat the consistency of pulling shots all day on a professional machine to perfect your espresso game, sure, but if you’re only dabbling with a daily cup of Americano with a model that’s right for your kitchen size or budget, there are still ways to dial up your espresso process to get the best possible result.

Kalina Teoh, Co-Founder and Director of Education for New York Coffee ProjectHe explains all the steps for preparing shots, so you can prepare espresso at home like a professional.
Espresso basics
Espresso is a precise brewing method, not a drink.
“The word ‘espresso’ itself is not just a drink, it is actually a brewing method that involves forcing hot water through a compact disc of coffee,” explains Teoh, which can be accomplished through a machine with a boiler, or by hand, such as in a stovetop espresso pot. It requires certain pressure and temperature calibrations, but no sophisticated machine is actually needed.
“The two most important things are the ability of the machine to maintain pressure and temperature while you pull the shot,” she says. On most models intended for home use, you may not be able to make any adjustments, but gauges or displays indicating pressure and temperature can be reassuring. Also make sure you closely follow the process outlined by the manufacturer, which may include a step to heat the water before brewing. Ensuring that your espresso machine is clean, by regularly cleaning the grounds at the portafilter loading point, and rinsing with hot water periodically, is also important for quality control.
More than the coffee machine itself, Teoh recommends using another important piece of equipment to get the best home-brewed espresso. “If you have a basic machine that can maintain the pressure and temperature, that’s good enough, but if I have the extra budget, I’ll put it in my mill,” Teoh says. “Having a good grinder, especially a good burr grinder, is very, very important for making espresso.”
Espresso Grinding: Grind size is important
Finely ground coffee beans are key to making the right espresso.
Since espresso is a processing process rather than a drink, there is really no such thing as espresso beans, and you can choose the source and roast of espresso that suits you best, even if it’s light. It is the grind of any grain you choose that has a huge impact on the outcome of the shot you pull.
“The grind size should be in the fine-grain range,” Teoh says, which is smaller than that used in drip, French press or pour-over coffee, but not as fine as the powder that can be used in unfiltered beverages like Turkish coffee. This element makes it even more important to have a grinder that allows you to adjust the grind size with a dial, rather than just a few preset settings, which may not provide the nuance you need.
Of course, Teoh also recommends using fresh coffee beans to get the best espresso. Grinding to order is great, but you’re also looking for beans that have been roasted as recently as possible, preferably within weeks.
Espresso has its own golden ratio
Just like drip coffee, espresso has its own golden ratio.
the “Golden ratio“It’s different for espresso than it is for drip coffee, fresh coffee, or pour-over, since you generally don’t have as much control over the amount of water that goes into the brewing process. Instead, you’re looking for a specific ratio between the amount of ground coffee and the amount of liquid coffee that comes out at the end, and yes, professional baristas weigh the final espresso to ensure Quality.
“The coffee-to-water ratio is between 1 to 1.5 and 1 to 2.5, which means for every 1 gram of ground coffee we put in there, we want to produce between 1.5 and 2.5 grams of liquid espresso in the cup,” says Teoh. “This ratio usually gives you a very good value, which is what we call ‘strength’. It won’t be too intense. It won’t be too watery either.” In order to make easy calculations while experimenting with these ratios, 1:2 is the average range to target. The smaller the ratio between ground coffee and liquid espresso, the stronger the coffee.
Despite the marketing language you might believe, there is no difference between coffee and espresso beans.
If your espresso machine has controls that allow you to adjust the strength of your coffee, you can try it. If not, other factors you can control, which can influence the result in terms of the ideal ratio, are the grind size, as mentioned above as well as the consistency and compactness of the disc.
Preparing the disc
Use your finger to gently level the grinding.
After measuring the grounds in the portafilter, according to its size and the manufacturer’s recommended measurement for a single or double dose, the next step is to level the filter before tamping it. “Use your fingers to make sure it’s evenly distributed before you press it,” suggests Teoh, so you don’t end up with an uneven disc. She explains that water will always look for the path of least resistance between the reservoir and the cup, so if there is an area in the portafilter that has a smaller or less-pressured volume of grounds because it wasn’t even to begin with, that’s where the water will go in the first place, resulting in improper extraction.
You should use a heavy, high-quality tamper that is the correct size for your portafilter. Portafilters come in different sizes, usually 51 or 54 mm in diameter for home espresso machines. If your machine doesn’t include a plunger or has a lightweight plastic plunger, you’ll need to upgrade it.
Your disc must be level and smooth before you hit the ball.
Tamping the disc doesn’t involve using extreme force, but “you’ll want to apply pressure to the point where it feels like it’s pushing back,” Teoh says. “You’re not using your full body weight on it, but it’s not like you’re stamping a card. You want to press down and create a dense, tightly packed disc.”
If you want to be precise with the pressure, some guidelines suggest applying between 20 and 30 pounds. Teoh notices that too Spring-loaded tamper Available, making it easier and more consistent to apply proper pressure.
What about cream?
Crema is less about flavor and more about mouthfeel.
A layer of cream or foam on top of the shot may be desirable, but is not necessarily an indicator of a properly drawn shot, nor does it significantly affect flavor.
Teoh explains that carbon dioxide gets trapped in the coffee beans during roasting, which is released during the brewing process and results in a foamy crema. However, it is not the density of the tablet that determines whether it will appear during fermentation or not. “Your crema isn’t just carbon dioxide, but it’s also oils and insoluble substances in the coffee,” Teo says. “There are a lot of aromatic compounds in it, but the actual flavor of your coffee is in the dark liquid at the bottom. The crema doesn’t carry a lot of flavor in itself, but it helps improve the mouthfeel.”
The absence of crema may have less to do with the mechanics of the shot and more to do with the roast itself. “The freshness of the coffee makes a difference, and some coffees, if they’re lightly roasted, won’t have as much crema as well,” Teo says. To maximize the cream’s potential, you’re looking more for dark roasted beans that have been recently roasted.
Taste and adjust
The golden ratio is a good place to start, but don’t be afraid to adjust if the flavor isn’t to your taste.
It’s your coffee, so your taste is what matters most to the end result. Small differences in coffee freshness and roast, grind size, ground coffee measurement, tamping pressure and consistency, and temperature – to the degree you can control it – will all affect different results. To get a balanced drink with a pleasant taste and longevity, keep experimenting with the above modifications until it works for you.
“You may not have experience making espresso, but you have experience as a consumer, so you know what you should taste in your cup, and if it’s not right for you, you know something needs to be adjusted,” Teo says. Given all the potential variables mentioned above, hopefully it’s just a matter of tweaking the little things, rather than needing a whole new system.
