I'm assuming it's one of those rotating type stations with centrifical "gravity." What I'm really wondering about is the question of water getting hot enough to make coffee in low pressure environments such as astronauts experience.

Gravity and pressure are different things.
Even in free fall (which you might mistakenly call zero G) the pressure is whatever you want to make it. Add more air, you have more pressure. Reduce the air, you have less pressure.
My understanding is that the air inside most spacevessels is higher than normal earth air pressure. But it certainly shouldn't be much lower or the Astronaughts will suffer from going to standard Earth sea level pressure to low pressure.
This means that the water will boil as normal.
It wouldn't be too hard to create a low gravity, no gravity/ low pressure, coffee machine. To replace gravity the coffee machine could rotate (just by hand spinning) or use differential pressure. Maybe instead of a drip different, you use a plunger to force the water through the filter.
The whole device would be sealed anyway to create the pressure and stop the water floating away.
Any budding inventors should draw up rough plans and email them to NASA.

If you can make coffee in a mountain city, you can make it on a space station. The air pressure on a space station is not that low.

They have coffee bags. Like tea bags. Which you soak in very hot water to "brew" coffee from real beans. That might work.
I mean you have to have pretty hot water to make instant melt effectively.

He would need a pressure cooker to get the temperature to the boiling point of water.

I'm pretty sure they wouldn't have taken a coffee maker with them.
though knowing Starbucks and Tim hortons they will find a way

no but eventually they can go threw the fly thru at tim hortons.
i hear timmy's coffee is out of this world
