How to Properly Maintain and Clean an Espresso Coffee Machine Espresso machines use pressure to push water through coffee grounds. This type of brewing results in a stronger drink than drip coffee. The machines require 9 bars of pressure to extract flavor from the grounds. Espresso machines are available in three major types. There are three main types of espresso machines that are semiautomatic, manually operated and fully automated. Semiautomatic machines permit you to control tamping, grinding and extraction time. They provide a great compromise between human control and machine reliability. Easy to use The top espresso machines are easy to use. They have an adjustable thermostat that keeps the temperature of the water at a suitable level, and a pressure pump that increases the amount water per shot. The higher pressure makes the grounds dissolve faster and creates a whipped cream with the ideal consistency. These machines also include a milk frother for making espresso-based drinks such as lattes and cappuccinos. Traditional steam-driven espresso machines utilize an airtight tank to heat the water until it reaches a boiling point, which releases the pressure into a shot of coffee. While they're inexpensive and compact they're only able to reach 1 or 2 bars of pressure, which is less than 9 bars needed for espresso. Semi-automatic espresso machines pour hot water into a portafilter that is filled with beans that have been ground and pretamped. The barista is responsible for the extraction process but must manually measure, grind and tamp each cup of beans. Although this type of machine is more expensive than other models it offers greater control and stability, according to Jai of Blank Street Cafe. Full-automatic espresso machines completely remove the barista from the coffee making process, which makes them more user-friendly than semi-automatic models. The majority of them have built-in grinders which click into the portafilter. They automatically grind and dose the beans, and can be adjusted to make various drinks. Some even have a milk hopper which can froth and pour milk for you. Easy to clean Espresso machines make use of higher levels of pressure and heat than drip coffee makers to make an intense, full-bodied shot. They also come with a milk-frothing system that allows you to make cappuccinos and lattes. They require more care than drip machines, including routine cleaning and descaleing. Fortunately that the majority of espresso machines are very easy to clean. A few models on our list were specifically designed to make cleaning easier. The majority of espresso machines have an in-built portafilter that holds the grounds of coffee while brewing. Certain models come with a grouphead that is a collection of parts that perform the extraction. Backflushing your machine regularly will keep these parts clean and free of gunk and grit. This involves cleaning and brushing the portafilter, locking it, and running the brew process multiple times. Backflushing is a common practice in many coffeehouses, however at home it should only be done once a week. The use of soft or filtered water is suggested, as this will help reduce the amount of mineral buildup and decrease your need to descale. It is essential to remember that a moderate amount is needed to extract. Too much mineral will muddle the flavor. A lack of minerals can result in an unsavory, salty coffee. Maintaining your machine will ensure that it continues to function well and taste delicious for as long as you have it. Easy to maintain A coffee machine permits you to prepare various coffee drinks. A carafe-style maker can achieve the same result, but an espresso machine needs more pressure and temperatures. To achieve this, the machine should be maintained and cleaned properly. You don't need to be an an expert in order to keep your espresso maker running smoothly. First, you'll need to thoroughly clean the gasket in your group each week. Here, the coffee oils may accumulate and cause bitter taste in the espresso. To get rid of this, backflush the group with a mixture of water and espresso machine cleaner. It is also recommended to scrub the screen of your group including the nooks and crevices with a nylon toothbrush or Coffeetool. It's also important to wash the drip tray regularly because it is the place where you collect the coffee waste that comes from each brewing cycle. This can be a perfect breeding ground for bacteria and mold which can alter the taste of your coffee. In espresso coffee machines , you should clean the exterior of your machine regularly to keep milk and coffee residue from building up. You should also consider using a milk system cleaner which is food safe and designed to clean components that come in contact with milk. These products are readily available in all grocery stores and are easy to use. Easy to repair A coffee maker or espresso machine is a very useful appliance in the office or at home.
