So far we have seen a cafetiere and an espresso machine. Whilst they both make nice coffee they are not very useful when you have lots of people around who all want coffee all the time! For that you need a filter coffee machine. They are easy to use (add coffee and water and leave alone), they keep the coffee hot, and they are easy to clean and refill when the coffee runs out. Again I went for a relatively cheap model, but it works a charm and makes it very easy for me to provide lots of coffee.
The next coffee machine I acquired, an espresso pot, was a present. An espresso pot is the exact opposite of the filter coffee machine in that it makes a single cup of coffee. Unlike the previous ways of making coffee this one is actually quite fun as there is a certain element of having to watch and wait for the coffee to be ready -- mainly so you don't burn the thing dry leaving it on the heat too long. As an added bonus it works quite well on an Aga.
