How to Properly Maintain and Clean an Espresso Coffee Machine
Espresso machines use pressure to push water through coffee grounds. This type of brewing makes more flavor than drip coffee. The machines require 9 bars of pressure to extract flavor from the grounds.
Espresso machines are available in three different kinds. They include manual, semiautomatic and fully automated. Semiautomatic machines permit you to control grinding, tamping and extraction time. They offer a good balance between human control and machine consistency.
Simple to use
The top espresso machines are easy to use. The top espresso machines have an adjustable thermostat that keeps the water at the correct temperature, and a pressure pump that increases the amount of water in each shot. The increased pressure makes the grounds to dissolve faster and creates a whipped cream with the right consistency. The machines also come with a milk frother for making espresso-based drinks, such as lattes and cappuccinos.
The steam-driven machines of the past use an airtight tank to heat water until it's boiling, and then release the pressure into a shot espresso. Although they're small and inexpensive, they can only reach only 1-2 bars of pressure which is less than the ideal 9 bars required for espresso.
Semi-automatic espresso machines pump hot water into a portafilter stuffed with beans that have been ground and pretamped. The barista is in charge of the extraction process, but must manually measure the amount of beans, grind and tamp each cup of beans. While this style of machine is more expensive than other models however, it gives more control and stability, according to Jai of Blank Street Cafe.
Full-automatic espresso machines remove the barista from the preparation process, making them much more user-friendly than semi-automatic models. Most have built-in grinders which click into the portafilter. They then automatically grind and dosing the beans, and are often adjusted to produce different drinks. Some even come with a milk hopper that can make froth and pour milk for you.
Easy to clean
Espresso machines utilize higher pressure and heat than drip coffee makers, resulting in a thick, full-bodied shot. They also come with a milk frothing system, which lets you make lattes and cappuccinos. This means that they require more frequent maintenance than a drip machine such as descale and routine cleaning. Fortunately, most espresso machines are easy to clean. Many of the models we have listed have been designed to make cleaning simpler.
Most espresso machines have a portafilter that holds the grounds of coffee during brewing. Certain models come with a grouphead that is a collection of components that actually perform the extraction. Backflushing your machine weekly keeps these parts clean and free of grit and gunk. This means cleaning and brushing the portafilter, locking it, and running the brew cycle a number of times. Many coffeehouses backflush their machines daily, but home users need to only do it once per week.
It is recommended to use filtered or softened water, since it reduces the accumulation of minerals and the requirement to remove scale. However, it is important to remember that a moderate amount of minerals are required to ensure proper extraction. Too much can overpower the flavor, while too little could result in the cup being weak and salty of coffee. Maintaining your machine will ensure that it is working well and taste great for as long as you have it.
Easy to maintain
A coffee machine permits you to make a variety of coffee drinks. A carafe-style maker can provide the same results however, an espresso machine requires an increased pressure and temperature. To achieve this, the machine needs to be cleaned and maintained properly. You don't have to be an expert to keep your espresso maker operating smoothly.
You'll want to clean the gasket every week. This is where coffee oils accumulate and could cause bitter taste of the espresso that has gone rancid. To remove this, flush the group with a mixture of water and espresso machine cleaner. It is also recommended to clean your screen including the nooks and crevices using a toothbrush made of nylon or Coffeetool.
It's also important to wash the drip tray regularly because it is the place where you collect the coffee waste that is generated from each brewing cycle. It can also become an ideal habitat for bacteria and mold which can affect the flavor of your coffee. In addition, you should clean the outside of your machine frequently to prevent coffee and milk residue from accumulating.
Think about using a milk system cleanser which is designed to clean all components that come into contact with milk. These products can be found in a majority of supermarkets. They are also simple to use.
