Buy a cafetiere (single serving one is best for portion control) and then buy any of the Taylor coffee depending on the strength that you like, they range from a 1 through to a 6. Personally I'm a 6 man 'lava java' is its name but 'lazy sunday' (3) is more than adequate for an given coffee drinker.

So for a single cafetiere...
One healthy table spoon of coffee in the cafetiere (3 in a normal sized one) and then pour in hot water and give it a quick stir and putting the lid on. DO NOT PLUNGE THE PLUNGER YET! allow around 5 min to pass, for something to do add milk and sugar as required into your cup. Waltz into the office with cup and coffee in hand, making everyone super jealous with the aroma of real coffee, plunge, pour, procrastinate.
