Should I grind my coffee beans at home, or en masse in the coffee shop? I bought a pack of New Orleans' PJ's whole bean coffee. It is a bit old, about a year. I am flexible type though, I'll drink it.

The problem is my indecision about whether to grind it piecemeal or just all at once. I have a cuisinart machine that works quite well. But it's for a small amount.

Curious as to the best way to ensure somewhat fresh cups.
That's pretty straightforward: if you're not too lazy and have the equipment at hand, always grind only the amound needed just before brewing.

Now if your beans are year old already, this might not make a huge difference --- but there's no way that grinding it all at once could help you have ``somewhat fresh cups''.
