I said this last time this topic was posted (been on GN too long!)
I have tried every machine and contraption going for making coffee - I cannot abide instant coffee and am really fussy about my brew. I have disposed of all of them, pods, filters et al. You never get a decent sized cup of hot coffee from the machines.
But once again, I am back to cafetières of different sizes, my SmartCafe cups (insulated mugs with a built in plunger) a large vacuum flask to keep extra coffee warm (hate saved coffee myself...) and a couple of over a cup filters. Columbian ground coffee every time, and yes, don't use boiling water.
