If you don't mind instant coffee granules or powder, it isn't that difficult to make a cup of coffee. You just put a teaspoonful of coffee in a cup or mug, boil some water, pour it on, stir and then serve. However, if you want "proper" coffee, not instant, the process isn't quite so easy unless you have a coffee machine.

There are many different types of coffee machine available and which one you choose will depend on the features and the price of the appliance. In a domestic environment, you don't necessarily need all the "bells and whistles" that a commercial enterprise would require, but if you want to make different types of coffee, you'll want something a little fancy.

First of all, you can choose the look and size of the coffee machine. If you only have a small space available, there's no point buying a huge machine and this may restrict the facilities that it has. For example, it will affect the number of cups of coffee which can be produced before the water reservoir must be refilled. In terms of appearance, there is either plastic or stainless steel to choose from and plastic may come in a variety of colours depending of the make of the machine.

Another early decision will be whether you want a filter machine with a jug or whether you want an espresso machine. The latter is usually more versatile but may well cost more to buy and you'll also need to buy more coffee as by it's nature espresso is usually stronger than filter coffee.

Filter coffee machines usually have a jug which sits on a hotplate to keep the coffee warm. This is useful if you have a lot of people drinking coffee, for example in an office, but although you can vary the number of cups you make, it isn't really practical for a lone coffee drinker (unless you drink far too much) because the hotplate doesn't really keep the coffee that warm over time and the flavour becomes a bit "stewed" if not drunk within an hour or so.

Espresso coffee machines, particularly really do come in all different shapes and sizes, from the tiny little one cup machines to the large (and expensive) types which have a large reservoir, grind the coffee, dispense and tamp it down then discards the spent coffee when the water has run through. All you have to do with one of these is make sure that there is enough water and beans then froth the milk if you want it.

Medium priced espresso machines will usually have a reasonably large water reservoir and a milk frothing system. Cheaper ones will probably only hold enough water for a couple of cups and won't have a frother. It's really horses for courses depending on how much and what sort of coffee you like to drink.

Many brands have similar models of coffee machine, so you may want to visit a few different electrical shops and compare prices, brand facilities and warranty conditions, before you make your decision.

Whichever type you buy, don't forget that there is different ready ground coffee for filter machines than for espresso machines so make sure that you pick up the right sort in the supermarket. Either way, once water has run through the coffee, don't even think about trying to use the coffee again or it will look and taste like dishwater!

If you choose the right coffee machine for the job, then you should have good tasty coffee whenever you want it.
