Espresso is a way of preparing coffee that uses high pressure hot water that goes through a filter then to the ground coffee. In this method of preparing coffee, the filter removes slightly harmful substances such as cafestol and kahweol.
Use the filter,and your stomach and heart will thank you if you’re older and have medical conditions that involve either organs. The filter also helps to keep the caffeine in the the coffee ground. The result is coffee that has a rich aroma and a pleasing taste. In my experience, only espresso coffee brings out the full smell and taste of the coffee beans used.
An excellent espresso follows these four rules.
1. An excellent coffee blend.
2. A thoroughly grind coffee
4. Professionalism and experience (This applies to just about everything these days.)
According to the National Institute of the Italian Espresso, excellent coffee, in addition, should also:
Have a weight of of 7 grams a shot.
Have a temperature of 86-90°C (186.8°F-194°F)
Have a volume of volume – 30-35 ml ground coffee for espresso.
Have a strong aroma – coffee aroma (different levels of aroma depend on the amount of arabica and robusta coffee ground is used);
Have a taste that isn’t sour or bitter. This is a good indication that the correct proportion of arabica and robusta ground coffee were used in preparation of the espresso. A taste that is neither bitter or sour also indicates that the beans used were of a high quality.
Have a crema that is light reddish brown to a dark reddish brown in color and is homogeneous.
Crema is a foam that sits on the surface of the espresso. It’s made up of vegetable oils, proteins and sugars.
The way coffee beans are ground is crucial . If the grinding of the beans is too coarse, the extraction from the beans will be undoubtedly weak, resulting in an inconsistent crema. The smell, the taste, and the nutrients of the coffee beans (proteins, minerals, vitamins, aromatic oils) will remain the the ground coffee or the filter. Coffee beans that aren’t finely grind will not dissolve sufficiently in hot water.
Adding “flavoring” to espresso is completely unnecessary. The true taste of espresso doesn’t require masking. Additives are present if there is a smell or taste that is similar to caramel, Irish cream, or almonds coming from what appears to be hot espresso. Additives are a cover-up for improperly brewed espresso and therefore should be avoided.
The container for espresso is also important to consider. Espresso like all coffee is hot so the best material for serving it has to insulate the heat from the hands that will handle the container. The white porcelain cup is the best container for espresso. Its thick ‘walls’ insulate the majority of the heat given off by the hot espresso. Porcelain cups are usually covered with a layer proof enamel. This ensures that the porcelain cup is not weathered or stained by the various organic acids that it’s exposed to in the coffee.
I know some people will appreciate the…creativity that goes into something like a square porcelain cup and will succumb to using one, I will still advise that you don’t since the shape will make it more difficult to stir. The elliptical shape of the traditional porcelain coffee allows the coffee to cool more quickly so a square cup will be hot longer. Besides, square cups are just odd looking! Don’t they remind you of a bad Bauhaus experimental piece?
Although the typical porcelain cup can hold 65-70 ml of espresso, the maximum amount that a cup should be filled with espresso is 30 ml. This allows to coffee to cool more quickly and reduces instances of spilling.
These specifications on espresso preparation come from the National Institute of the Italian Espresso, which is based in Italy. In Italy, coffee brewing is considered a serious profession. Preparing of special blends of espresso is an art that has been polished for centuries, by the Italians.
If you are looking for an expert on espresso, he or she will most likely be Italian. The National Institute of Italian Espresso gives rigid guidelines to manufactures of coffee and coffee equipment to ensure that a certain standard is kept across the board. The manufacturers generally adhere to these standards because they know it’s not just the National Institute of the Italian Espresso that holds those standards, it’s the Italian people. The National Institute of the Italian Espresso also provides training to people who wish to learn how to prepare the legendary drink.
Well, folks, we’ve come to the end of today’s journey. It’s been a long one but one I hope has been educational as you continue on your journey on becoming coffee connoisseurs.
Thank you for reading.
