I grew up thinking coffee was this thin, water-like substance that my parents drank with their breakfast. It came from a jar, and after being added to water, was mixed with great gusto until coffee was produced. I remember taking a drink once and saying, Ick. For years, my coffee adventure was at at standstill.
Throughout college, I drank a semblance of coffee known as drip, more for the caffeine punch during late night study sessions. I still could not fathom coffee being anything more than a lightly drug-laced liquid experience.
Then, following graduation, I was introduced to espresso. And my coffee world was turned upside down.
Espresso is still coffee. But the way it is blended, roasted, and produced makes it into something so very much more.
The finest espresso in the world begins its life as high quality Latin American coffee beans. Other coffee producing venues (Africa, the South Pacific, etc.) could also lend their produce to espresso, but in my experience, it is the high, mountain grown beans of Latin American that yield the finest espresso blends.
After choosing the right bean, this delight is off to the roasters. All coffee is roasted. But it is the job of the roaster to bring out the unique, tantalizing flavor that each geographical blend has to offer. For espresso, the roast is slow, rich and deep. By taking the required time with these beans, the espresso roast produces a dark, oily bean. When properly prepared, this roast allows for an amazing, Carmel-like characteristic to emerge from the espresso.
But roast alone cannot bring to life the beverage we know as espresso. Much of its beauty is owed to the preparation of the drink. The beans are ground much finer than say a coffee bean destined for the drip coffee maker. The fine, powdery grind forces water to take its time as it pours through the espresso, pulling out the unique and subtle nuances of the bean and its roast. This process is aided by the use of a espresso machine, which uses steam to pressurize and force the water through the ground espresso. As the water is squeezed through the coffee, a three-tiered drink appears, with the espresso tumbling and cascading from the machine into commonly used shot glasses. When allowed to settle, you can see the three parts of brewed espresso - the crema, the body and the base (which, if allowed to set more than a few seconds, will turn the shot bitter).
While espresso is enjoyed on its own, often it is added to steamed milk and flavorings to produce cappuccinos and lattes. It is amazing rich, carmely goodness is distinguished in the drinks it accompanies a definitive, bold coffee punch that is layered with various other flavors.
Espresso helped open the doors of my coffee experience. If you are fortunate, you, too, will be won over by its sirens call.
Caffeine In Espresso Coffee
I do believe that once you've had this Italian style coffee, it is hard to go back to regular drip filter coffee, although French plunger coffee can be fantastic too. Of course, when you need a 'pick-me-up', any coffee will do!
What is the difference between drip and espresso coffee? Italian coffee is made very differently. It uses a high pressure to force water through the ground beans. Interestingly, whilst the water is very hot, it is not boiling. And the beans themselves are ground very fine and smooth. Contrary to some commercial presentation, this style of coffee is not dependant on one type of bean or roast. It is the process of making the beverage that makes it espresso coffee, nothing else. When a cafe refers to a dark, or stronger roast as an espresso roast, it is no more than an idiosyncrasy of marketing. All coffee beans used to make Italian coffee could be called espresso beans or roasts.
Espresso coffee has a foamy, creamy top made of protein, vegetable oils, and sugars. These all come from the beans, as do the dissolved solid that make up a higher percentage in Italian coffee. This process of coffee making produces a beautiful, intense flavor and aroma.
There is both an art and a science to making a good cup of espresso coffee. Modern coffee chains, particularly the franchises, use standardized temperatures and methods, whereas in Italian communities it is a combination of experience, intuition, individuality, and tradition. The franchises don't even come close to the quality of the coffee made by a good barista using the traditional Italian approach. Having said that, there are a lot of ordinary (and some downright bad) baristas out there who could possibly do well with following a more standardized approach.
To make good espresso coffee, you have to be careful about the temperature of the water used. If it is too cool, the result will be sour. If it is too hot, it can be bitter. Similarly, if you are heating milk to mix with it, burning or overheating the milk will affect the quality of the drink. This is particularly true when using soy milk - overheating it can cause it to separate, and the taste is very bitter and unpleasant. Unfortunately, this is sometimes the case with inexperienced baristas.
The shot of coffee made by the espresso coffee maker also has to be used immediately. When it is left for any length of time, it begins to oxidize, and the quality deteriorates. Most commercial coffee houses have policies taking this into account. And it's a good thing to remember if you're making coffee with home equipment.
