Espresso machines are a popular type of coffee maker. There are many different types and sizes to choose from, but they all have the same primary function: making espresso. If you want to buy an espresso machine, make sure to read our article first! We’ll teach you everything you need to know before making your purchase.
1. What is an espresso machine, and what do they do
If you want to make a good espresso, water is forced through a compacted bed of coffee. Espresso machines contain an electric pump, which forces the water through the coffee at about nine atmospheres of pressure (at sea level). This allows for the efficient extraction of flavour from the coffee.
2. Types of espresso machines
There are five main espresso machines: manual, semi-automatic, super-automatic, pod and steam.
Manual: With this type, you’ll have to heat up and pump the water yourself. This may be more work than it’s worth to some people!
Semi-automatic: These machines will heat up and pump the water for you. However, they require that you grind your beans and tamp them down to use them.
Super-automatic: These machines not only heat up and pump the water for you, but they also grind your beans and tamp them down.
Pod: Some people prefer to use pre-packaged coffee pods instead of buying whole beans or grinding their own.
Steam: This type does not force the water through the coffee as it makes espresso, as other types do. Instead, steam is forced through the coffee very quickly by pushing steam through a small tube leading into a heating chamber containing water.
3. The features you should look for when buying an espresso machine
If you want to buy an espresso machine, there are many features to consider. Make sure you read our buyer’s guide before buying! But here are some important things to consider:
-Price: The most expensive machines are not necessarily the best. Cheap models can have just as good an effect on your espresso as more expensive ones do.
-Size: A small machine may be perfect for a single person, but larger families need to buy bigger machines that hold more water and beans.
-Material: There are many different materials that espresso machines can be made out of, including aluminium, plastic, stainless steel and porcelain. Aluminium is lighter in weight but weaker than most other metals.
Stainless steel is very durable with excellent heat retention properties. However, it does dent if hit hard enough or dropped on the floor.
Porcelain enamel is another durable metal that has excellent heat retention properties. However, it is very heavy and can be dented if hit against another surface or dropped on the floor.
Plastic is a compromise between weight and durability. It does not retain heat and metal, so you will have to wait longer for your espresso water to heat up again.
Fortunately, most machines with plastic outer casings do come with insulated carafes and drip trays to help keep your coffee warm until you’re ready to drink it.
Water capacity: How much water does your machine hold? Most machines hold about 54 ounces of water at a time (about 1350ml). Some smaller machines only hold about half that much! If you make espresso heavily every day or like drinking large cups of coffee (over 14 ounces), you’ll want to buy a machine with at least an 8-cup (1350ml) water capacity.
