The popularity of coffee increased and it was soon a highly sought after trade. Over time, people in Europe and the Americas were soon having a cup of coffee to replace other traditional morning drinks. In Europe, some were suspicious of the possible evils of the new black liquid. After papal sampling and approval, it was considered safe and delicious. It wasn't long before coffee became know and consumed worldwide.
It's popularity sparked new businesses in trade, coffeeshops, specialty roasters, and of course created a world of coffee debate. Coffee aficionados can be found in every corner of the world. Coffee is currently the second most sought after commodity, just behind crude oil! Simply put, espresso can be made with any type of coffee bean.
The secret to making espresso beans so unique is the roasting process. One difference is that true, traditional espresso is typically made with a darker roasted coffee bean. Another difference between espresso and coffee grounds is the way they are roasted. Espresso beans are roasted longer and darker than light or medium roasts which causes caramelization and an overall sweeter taste.
These beans are typically roasted past the second crack which means they crack open a second time in the roasting process. The long, dark roasting removes a lot of the acidity, but more importantly, this extraction process pulls oils from the bean that translates into a heavier, fuller concentrate. In addition to using dark roast coffee beans, there is a specific espresso grind.
In order to pull a true, crema-rich shot of espresso, the coffee is very finely ground so that it can be tamped down in the portafilter. If the beans are not tightly compacted, the water finds a shortcut through the grinds and produces a watered-down version that is more like a regular cup of coffee. Now we know that there are not specific espresso beans. If you do see a bag of espresso coffee at the grocery store, most likely it is a bag of darkly roasted, finely ground beans.
You can undoubtedly grind your own espresso beans at home with a coffee grinder, they just need to be super fine and consistent! Most people assume that espresso has a higher caffeine content than a cup of black coffee. It is not the caffeine content that is the difference, it is the caffeine concentration. The serving size of a shot of espresso is one ounce. Espresso contains a higher concentration of caffeine per serving size.
A cup of regular drip coffee is about 8 ounces. There is less caffeine per ounce in a cup of drip coffee, but the caffeine content could actually be higher, depending on the amount of coffee in the mug.
Espresso machines were first dreamed up by Italians in the late 19th century 1 — a lot of scientific know-how was required to make it work. In comparison, pour-overs are a much simpler method of brewing coffee. Technically, all you need is some water and coffee grounds to make magic happen. There have however, been major innovations in pour-overs as well, particularly from Japan 2.
In the end, it boils down to skill: a good barista will be able to make the most of any brewing method. Chances are you were raised thinking that an espresso has WAY more caffeine than a cup of coffee.
And, as you might expect from the above sentence, the correct response to that is both yes …and no. See, if you take an equal amount of espresso and coffee , then yes, absolutely the espresso will have much more caffeine. But that should be no surprise, right? Especially since everyone and their mother knows that a tiny espresso shot is absolutely LOADED with all sorts of flavors and elements in a much more concentrated way than you get in coffee.
Now, as is the case with most culinary facts, the specific numbers can vary quite a bit here depending on the beans you use, the brewing method, the temperature of the water, extraction time, and so on.
However, on average , a typical cup of coffee has between 80 and mg of caffeine. Some even put the higher end of the caffeine content up towards mg! On the other hand, your typical shot of espresso is going to yield right around 60mg of caffeine , with the higher estimates usually still being below that 80 mg lower threshold for a cup of the brewed stuff. You can see a thorough breakdown of the caffeine concentration in some brewing methods here! You can even do an experiment using a good coffee refractometer.
All coffee comes from the same source, the Coffea plant. Rather than the beans themselves, the difference between coffee and espresso derives from the way they are processed and brewed. When coffee beans are harvested, they are pale green, and unfit for brewing. They need to be roasted to bring out their best qualities. Espresso beans are roasted until very dark, because this increases their capacity to withstand the high pressure under which they are brewed.
A dark roast also brings out a full body with low acidity, and is well suited for drinking with milk 3. Simply put, most roasters and consumers seem to prefer espresso to be roasted a little darker when it is to be consumed in milk rather than black. Lighter roasts are especially well suited for pour-overs, which tend to bring out the brighter, fruitier flavors of the coffee.
To put that figure in perspective, you would need to dive nearly feet deep in the ocean to experience optimal espresso pressure. After pressure, the size of the coffee grounds is paramount. We generally recommend fresh, medium ground beans when brewing your coffee with a drip filter or percolator.
When making coffee in a French press, setting your grinder to make coarse grounds will strike a balance between releasing delicious coffee flavors without wasting or dissolving the particles — too much saturation in the grind makes coffee more bitter. But espresso is different. The properties of the coffee cake, also called the coffee bed , determine how well the espresso is extracted. The smaller grind exposes more surface area of the beans to water.
This means more efficient brewing through the short infusion process. Of course, grounds that are too fine can clog or slow the brew. Another difference between espresso and coffee shows up in the serving size.
The average size of a cup of coffee is 8 ounces, but a typical espresso shot is only one ounce. This is because espresso is thicker and more concentrated than regular brewed coffee, so with such a bold taste, less is definitely more.
Traditionally, this dark brew is served in an unassuming China cup that can fit barely 50 milliliters about 1. This delightful foam is the primary visual indicator of a well-extracted shot of espresso. When pressurized water is forced into the coffee cake, several reactions are thought to happen:.
All these forces come together to create the top layer of the espresso shot. Generally, the crema can hang around for about 40 minutes — assuming your shot lasts that long. After all, espresso is Italian for expressed , as in this espresso was made for the express purpose of you drinking it immediately after brewing. When brewed properly, the actual espresso under the crema will have a unique, rich taste , velvety mouthfeel, and aromatic scent. The shorter period of water exposure draws out less acid than other brewing methods while still retaining 60 to 70 percent of the caffeine in the final cup.
So even though it takes only 30 seconds to brew with an espresso machine, it still provides a significant amount of caffeine. The short answer is no. Espresso, like black coffee , actually has a lot more health benefits than disadvantages.
At a pretty basic level, espresso is high in antioxidants and low in calories, which present some pretty obvious benefits. While caffeine is responsible for the highly sought-after energy boost , there is actually a limit to how much you should be drinking. Espresso is not only good for making your favorite coffee drinks, but it just might be good for you, too, boasting some rather impressive health benefits. Furthermore, some people actually use espresso to boost their workout performance.
In comparison to the average cup of drip coffee, some might consider espresso to be the healthier choice because brewing it requires no filter, meaning espresso contains more natural nutrients than a cup of drip. Consuming too many of these natural oils has been linked to high cholesterol, though, so consider monitoring your unfiltered coffee consumption.
More good news for espresso drinkers: espresso is notorious for its low acidity. This is because the longer coffee beans are roasted, the more their chlorogenic acids are decomposed. So, any dark roasted coffee bean , like one intended for espresso, will boast a lower acidity than a light or medium roast. Caffeine is known to cause insomnia and increase the symptoms of anxiety.
Additionally, excessive caffeine can lead to high blood pressure.
