The Filter Holder: Essential Gadget in Coffee and Espresso Machines
Mastering the Basics: What is a Filter Holder?
A filter holder stands as a foundational component in a coffee or espresso machine. It securely holds the coffee filter, filled to the brim with ground coffee, and slots into the brewing group of the machine.
In espresso machines, the filter holder often goes by the name of "portafilter." Predominantly made from stainless steel today, these portafilters usually feature a handle made of plastic or wood for comfortable handling. When it comes to filter coffee machines, the term "filter paper holder" becomes more pertinent.
Historical Overview: The Inception & Evolution of Filter Holders
So, how did filter holders become linked with the intricate art of preparation?
Initially, coffee wasn't prepared using filters. Rather, ground coffee was boiled with water, and then strained through a sieve to separate the coffee grounds from the brew. It was a labor-intensive process that often resulted in a bitter tasting coffee.
During the 18th century, a more sophisticated method began to gain momentum. This new method separated the coffee grounds from the water during brewing. This separation ensured only the soluble components ended up in the coffee while the coffee ground was left behind.
Various types of filters were used, including filters made from blotting paper or linen, placed in a funnel. Permanent filters were also common, which functioned like a sieve. However, the game-changer appeared in 1908 with the invention of disposable paper coffee filters by the Melitta company. Accompanying these were the specially designed filter holders for traditional filter coffee, making waves in Germany and beyond.
Maintenance tips: Cleaning the Filter Holder
Cleaning the filter holder depends on its type and material. For detachable models, it's generally as easy as rinsing them with water. Cleaning the filter holder from a portafilter machine, however, requires some special care.
A degreasing cleaning agent specifically designed for portafilter machines is needed for this task. The filter holder, without the filter screen, is placed in a container filled with a mixture of cleaning agent and water. After leaving it for approximately half an hour, the filter holder just needs a rinse under warm, running water, and it's good to go again.
Final Note
A coffee or espresso machine is only as good as its components, and the filter holder is among the essentials. This simple contraption bears massive responsibility in preparing a sublime cup of coffee or espresso. Whether you're an espresso aficionado or a filter-coffee enthusiast, the filter holder is an unsung hero behind every delicious brew you sip. Understanding its function and importance can make you appreciate your coffee even more, not to mention help you brew a better cup!
