Espresso Explained: A Simple Guide for Everyday Coffee Drinkers

Espresso has a reputation for being complicated and a little intimidating. You walk up to a cafe counter, see a menu full of Italian words and size options you do not fully understand, and end up just ordering what you always order because it feels safer. But espresso is not nearly as mysterious as it seems and once you understand the basics you will feel a lot more confident about what you are ordering and why you actually enjoy it. At Humble Coffee we think everyone deserves to feel at home at the counter, so here is a straightforward breakdown of everything you need to know.

What Espresso Actually Is

Espresso is not a type of bean or a roast level, which is one of the most common misconceptions out there. It is a brewing method. Specifically it is the process of forcing a small amount of hot water through finely ground coffee at high pressure in a very short amount of time, usually around 25 to 30 seconds. What comes out is a small concentrated shot, typically about one to two ounces, with a rich thick body and a layer of reddish brown foam on top called crema. That crema is a sign of a well pulled shot and it carries a lot of the aroma and sweetness that makes espresso so satisfying. The pressure involved in the process extracts flavors much more intensely than other brewing methods which is why espresso tastes so bold and complex in such a small volume.

The Building Blocks of Every Espresso Drink

Almost every espresso based drink on any cafe menu is built from just two things, espresso and milk. Understanding how those two elements are combined in different ratios is really all you need to decode the menu. A straight shot of espresso served on its own is called a single or double depending on how many shots are pulled. An Americano is simply espresso with hot water added to dilute it to a drip coffee strength, which is a great option if you love the flavor of espresso but want something you can sip over a longer period. A latte is espresso with a generous amount of steamed milk and just a thin layer of foam on top, making it the smoothest and mildest of the milk based drinks. A cappuccino uses the same amount of espresso but with less milk and more foam, giving it a stronger coffee flavor and a lighter airy texture. A flat white sits somewhere in between, with a smaller volume than a latte and a higher ratio of espresso to milk that gives it a bolder punch without being as intense as a straight shot.

What Makes a Good Espresso Shot

A well made espresso shot is the result of a lot of variables lining up at the same time and even experienced baristas are constantly dialing things in. Grind size is one of the most important factors. Too coarse and the water rushes through too quickly without extracting enough flavor, leaving you with something sour and thin. Too fine and the water struggles to push through, over-extracting and producing something bitter and harsh. The dose, meaning how many grams of coffee go into the portafilter, and the yield, meaning how many grams of liquid come out, also matter enormously. A small change in any one of these variables can shift the flavor of the shot noticeably. This is why a good barista is not just someone who presses a button. They are constantly tasting, adjusting, and paying attention to what the coffee is telling them.

At Humble Coffee our single origin approach adds another layer to this. Because we are not working with blends designed to taste consistent regardless of conditions we have to know each coffee intimately. A naturally processed Ethiopian bean pulls differently than a washed Colombian one and our baristas learn those differences so that every shot we pull is doing justice to the farm it came from.

Milk Matters More Than You Think

If you are a latte or cappuccino drinker the quality of the steamed milk in your cup is just as important as the espresso itself. Good milk steaming is about creating a texture that is smooth, velvety, and evenly integrated rather than bubbly or separated. Baristas heat the milk while simultaneously introducing air in a way that produces what is called microfoam, tiny bubbles so fine that the milk takes on an almost glossy silky consistency. When poured correctly into espresso it blends seamlessly and creates that soft creamy mouthfeel that makes a great latte so comforting. Non-dairy milks behave differently and some froth better than others. Oat milk in particular has become a favorite in specialty cafes because it steams well and has a natural sweetness that complements espresso nicely.

A Few Things Worth Knowing Before You Order

There are a handful of small things that tend to confuse people at the counter and are worth clearing up. Size does not always mean more espresso. At a lot of cafes ordering a larger latte just means more milk, not an extra shot, so if you want a stronger drink ask for an extra shot specifically. Ristretto and lungo are variations on a standard espresso shot. A ristretto is pulled with less water and a shorter time producing something even more concentrated and sweeter. A lungo uses more water and a longer pull giving you more volume and a slightly more bitter edge. Cold brew and iced espresso are also not the same thing. Cold brew is coffee steeped in cold water for many hours while an iced espresso drink is a hot shot pulled fresh and poured over ice, which gives you a brighter and more intense flavor.

Espresso is one of those things that rewards curiosity. The more you ask, taste, and pay attention the more you start to notice and appreciate what goes into a really well made cup. Next time you are in at Humble Coffee do not hesitate to ask your barista what they are pulling that day or what they would recommend. We love talking about this stuff and we think you will love what you discover.
