How to Properly Maintain and Clean an Espresso Coffee Machine Espresso machines make use of pressure to force water through coffee grounds. This type of brewing creates a stronger beverage than drip coffee. These machines require nine bar of pressure to extract the flavor from the ground. There are three major kinds of espresso machines. They are semiautomatic, manual and fully automated. Semiautomatic machines allow you to control the grinding, tamping, and extraction time. They are a good balance between human control and mechanised consistency. Easy to use The top espresso machines come with an intuitive interface. They have an adjustable thermostat that maintains water at a consistent temperature, and a pressure pump that increases the amount of water used per shot. The higher pressure allows the grounds to dissolve faster and creates a whipped cream of the perfect consistency. These machines have a milk frother to prepare espresso-based drinks such as lattes and cappuccinos. The steam-driven machines of the past make use of an airtight tank to heat water until it reaches boiling point, and then release the pressure to create a shot of espresso. While they're affordable and compact however, they only have 1 or 2 bars of pressure, which is less than the recommended 9 bars required for espresso. Semi-automatic espresso machines function by infusing hot water through an already-ground, pre-tamped portafilter of beans. The barista handles the extraction process but has to manually measure, grind and tamp each cup of beans. Although this kind of machine is more expensive than others it offers greater control and stability, according to Jai of Blank Street Cafe. Full-automatic espresso makers are simpler to use than semi-automatic machines since they eliminate the barista's role in the coffee making process. Most have built-in grinders that click into the portafilter. They automatically grind and dosing the beans and can be altered to create various drinks. Some even have a milk hopper which can do the frothing and pouring for you. Easy to clean Espresso machines create a richer, more full-bodied shot by making use of greater heat and pressure than drip coffee makers. They also have the milk-frothing mechanism that allows you to make cappuccinos and lattes. They require more care than drip machines, and require regular cleaning and descale. Fortunately that most espresso machines are easy to clean. Several models on our list have been made to make cleaning easier. Most espresso machines have an in-built portafilter that holds the grounds of coffee while brewing. Some models feature a grouphead that is a set of pieces that do the extraction. Backflushing your machine every week keeps these parts clean and free of grit and gunk. This involves cleaning and brushing the portafilter, locking it, and running the brew cycle several times. Many coffeehouses backflush the machines on a regular basis however, home users should only have to do it once per week. The use of soft or filtered water is recommended as this will help reduce the amount of mineral buildup and cut down on your need to descale. However, it is important to remember that a moderate amount of minerals are required to ensure proper extraction. Too much mineral will muddle the flavor. Too little can result in weak, salty coffee. Making sure your machine is properly maintained will ensure that it will continue to function well and taste delicious for as long as you own it. Easy to maintain espresso coffee machine is a magnificent piece of equipment which allows you to serve a large variety of coffee drinks. But unlike your average carafe, an espresso machine requires a higher degree of pressure and temperature in order to produce the desired results. To achieve this, the machine has to be cleaned and maintained properly. Thankfully, you don't have to be an expert to keep your espresso machine running smoothly. First, you'll need to thoroughly clean the gasket in your group each week. In this area, coffee oils can collect and cause bitter taste in the espresso. To clean this up, backflush the group using a solution of water and espresso machine cleaner. You'll also need to scrub your group screen including the nooks and crevices using a nylon brush or Coffeetool. The drip tray is important to keep clean as it holds all the coffee waste after each brew cycle. This could become an ideal breeding ground for bacteria and mold, which can alter the taste of your coffee. You'll also need to wash your machine's exterior regularly to prevent the accumulation of coffee and milk residue. Take a look at a milk system cleanser, that is designed to cleanse every component that comes in contact with milk. These products are readily available in many grocery stores and are easy to use.
