Espresso Based Drinks You Can Try
17th May 2019
Espresso is both a brewing process and beverage invented by the Italians. The name implies speed and singularity of purpose. There are a combination of variables that go into a single shot of espresso – beans, roast, grind, dosage, coffee pack, pressure, temperature and time which can all yield many outcomes.
The Anatomy of an Espresso Shot
Traditionally, an espresso shot is a dark brew served in an espresso cup and is topped with a thick layer of brown, bubbly crema, also known as coffee foam. It is finely ground coffee that is brewed under pressure and plays a big part in coffee culture. To pull the perfect espresso shot you will need a quality espresso machine, grinder, portafilter, tamper, fresh coffee beans and an espresso cup.
The cream is a top layer of foam that acts as a visual indicator of a well-extracted shot of espresso. Crema is a flavourful, aromatic froth that rests on top of a shot of espresso and is formed when air bubbles combine with fine-ground coffee oils. It is also known as the “Guinness effect” because it mimics the head on a pour of the Irish stout.
The presence of the crema indicates a quality, well-ground coffee giving it a long aftertaste and an ultimate coffee experience. If you have too much crema in the cup, you will have less espresso. The goal is to pull a shot of espresso with a crema that is not too thick, or too thin and lingers for about two minutes.
The extraction process from a quality espresso machine should take between 15 and 30 seconds.
Factors that Affect Crema
Freshly Roasted Coffee Beans – Are the coffee beans you are using roasted to perfection? Freshly roasted beans form more crema on an espresso because the coffee bean oils are still out-gassing from the roasting process.
The Colour of your Coffee Beans – The darker the bean, the less crema you will have due to the oils rubbing off while handling packaging and grinding.
How They Are Processed – Naturally processed coffee beans will produce the best cream because more coffee oils are left intact.
The most important part of the anatomy of an espresso shot is of course, the espresso. The espresso under the crema will have a unique, rich taste and aromatic scent. The shorter period of water exposure draws out less acid than other brewing methods while still retaining between 60 and 70 percent of the caffeine in the final cup.
The espresso shot is also made up of soluble liquids that make up the brew and taste, soluble gases make up the aroma of the espresso and insoluble solids that contribute to the mouthfeel of the espresso.
The Consistency of an Espresso Shot
The high pressure used during the extraction process results in an excellent concentration of flavours, meaning the espresso shot works well for blending into speciality espresso drinks and shots, such as cappuccinos and lattes without loss of flavour due to dilution.
