Another vote for Nespresso, if you can get one in budget. I have a Citiz Milk, which hits all my requirements for an easy espresso, a ‘normal’ black coffee and an occasional breakfast latte or capucinno with the milk whizzer. I was worried that I would get bored with every coffee tasting the same but with a choice of 10-12 basic varieties, plus extras, each cup tastes different enough to remain interesting… Or, of course, find the one you like and stick with that.
Various friends, family have different machines, but nespresso – to my mind – are the ones that have hit the realistic, least artificial but still easy coffee experience.
Not sure what the pods cost in the UK, but I pay the equivalent of about 30p per cup. I drink no more than one or two a day, so that is fine by me. You can mail order the pods but I find delivery is expensive. Would be more appealing if there was a stockist for the pods near where you live.
