They have lots of restaurant contracts -- McDonald's, for one. Every once in a while I run into in a hotel room, too. It's an old family-owned business. It is now run by the sons of the "D" original owner. Nice people -- they go to my church and donate to the nonprofit I work for.
I used to drive by S & D every single day on the way to work and again on the way home. Now, I only go by there a couple times a week. If you're ever in Concord, they have a nice little store in the back of the plant with a pot of free coffee brewing.
S & D used to contract out the roasting for their flavored coffees. A few years back I was a volunteer taste tester when they were perfecting the recipes/methods for doing it on site. I got a free 1/2 pound of coffee, which I evaluated for them. I think I did it three times.
