As far as Peet's goes, Major Dickason's is good. It's the first Peet's I ever had. I like Big Bang from Peet's a little better. But in terms of the best coffee I've ever tasted, it's definitely Pablo's Black Label. Pablo's is a coffee shop in central Denver and the founder is really into sourcing the best beans in the world. I order it 10 bags at a time and drink 6+ cups every weekday. Give it a shot, if you're into coffee, you'll love it. Trust me.
