Surprised I do not see De La Paz on the list. They are San Francisco roaster that has been around for more than a handful of years now, started slow and are just now going to open their own shop sometime this year.
I have never been done wrong by their single origins, and their espresso is in the seasonal ever changing variety.
I really enjoy their Mission blend as a hearty cup of coffee, very nice Sumatran in it that gives it a dark spicey note that I really love when in the mood for a darker roasted. Weird I did not see it on their website ho as I just got a bag yesterday. Don't let that fool you tho they are definitely a light roast sort of place, just glad they do the dark justice.http://www.delapazcoffee.com/
