Oh man I absolutely miss drinking coffee. Nothing beats a freshly grinded strong black coffee in the morning.
I'd use to order boxes of beans which had different packages from all over the world, it's only when you compare these directly that you notice how much coffee can differ in flavour. My wife really likes Costa Rican coffee since it's a bit milder. Me personally prefer the stronger ones
I like mild because I drink coffee almost exclusively as my only liquid intake and I have it in my cup all day, during every waking hour. Doesn't keep me awake anymore, I sleep fine. I just like the warm smooth flavor, and combined with some milk and sugar, tastes good, and helps sooth a bit of heartburn I tend to have in my older years now.
Yay coffee! And especially Costa Rican coffee. I'm voting with your wife on this one.
