While I'm not a complete coffee snob yet, I am fortunate enough to work at a place where we grind our own beans for coffee each morning. This produces a drinkable cup of coffee (we also use filtered water).
Anyways, we've got some new people staying with us for a little while and they brought their own coffee (pre-ground, cheap stuff). Now it's been a long time since I've had pre-ground coffee and I must say, how can you drink this stuff???? It's terrible.
I think we're going to need to train them on how to grind coffee, or get another coffee pot. Thankfully, I have tea that bridging the gap.
