Coffee is a favourite beverage which has become an unavoidable item in the family shopping list. Traditional methods of coffee making were time consuming processes. The manual methods resulted in wastage of coffee beans due to under extraction. The machines helped to save energy and raw material while making a rich and aromatic concoction. 

There are several types of coffee makers available today. Espresso, the strong and concentrated black coffee is made using steam pressure. The frothy beverage is liked by people for its consistency and flavour. Even though coffee can be made in other forms, espresso is the universally accepted mix for which many crave for. 

The main categories of espresso coffee makers are pump machines and steam machines. The original machine could be used only to make espresso, but later versions are with facilities to make cappuccino, which contains frothy milk. The milk will be stored in a separate spout.

The pump machines will be provided with a separate tank for water which will be boiled.  A thermostatically controlled boiler will heat the water to the required temperature. The water is then pumped through the ground coffee. The main advantage is that water can be added in between the operations without waiting for the machine to cool down as required in the case of steam machines.

Steam operated machines have an internal chamber for boiling water which will be passed through the ground coffee under steam pressure. As mentioned above, to make larger quantities of coffee, it is necessary to wait until the machine becomes cool.

The stove-top espresso coffee maker is a very popular machine.  The process is very simple. Water will be poured into the base pot and the ground coffee in the chamber above. The unit is then kept on the stove. The coffee made in this unit will be strong. It is ideal for small families and also cheaper in price.

The latest version of espresso coffee machine is Nespresso. This can be used to make not only espresso, but also other varieties like latte or cappuccino. Sealed capsules or pods containing roasted coffee are used in this machine to ensure quality and consistency of the decoction. Such sealed packages are available in different flavours. 

Another type is bean to cup model. Coffee beans can be used in this machine instead of ground coffee. The beans will be ground within the machine before getting brewed. All different varieties like espresso, latte and cappuccino can be made in this model.

Consumers should carefully choose the type of coffee machines depending on the type of coffee drink they require. The quality and the operating convenience are to be taken into account in this context. The required capacity is also to be considered while shopping for the coffee maker. Whatever be the type or category, the coffee machine should be maintained properly to ensure durability. The online shopping is a convenient option to choose the right type. Enquire and verify the merits and demerits of each category. Many reputed brands are available with foolproof warranty, free shipping and after sale service facility.
