We all have different ideas, on what coffee should taste like, so everyones advice will vary
A lot.. going out to buy a coffee filter and then the coffee beans, can be an expensive outlay
And of course which coffee beans ?. Strong or medium..

For me Millicano decaf ( medical reasons). I always drank Nescafe Alta Rico until the caffeine ban but hey.

Waitrose have all Millicanos on half price offer (2.50£) so I just stocked up. ( jan.7th)
