HI guys,

Does anyone know the best way to use these mugs?

If you dont know what I am talking about it bascially a thermal mug with built in plunger.

I am just wondering how much and what grind I need to use for this mug.

(I only bought this cos I refuse to drink the instant coffee that work supplies and do not want a part of any coffee machine that work buys, as people cannot keep the work kitchen clean now when they only have to rinse their own lunch stuff let alone trust these people to clean the coffee machine correctly so as not to leave bacteria around) (I can tell you now, these people WILL NOT clean a coffee machine cos that is what they are like)

Thank you for any advice...
