Cafe Du Monde coffee is roasted and packaged by Reily for Cafe Du Monde. It's a private label job. CDM is their (Reily's) in-house brand. So they're both the same company. Not sure how the flavors compare.
I'm not sure what the difference is, but I've seen the tin cans in Rouses, Walmart, Walgreens on Canal and Carrolton, and Winn-Dixie. I've even bought them a few times!
However, I enjoy French Market more so I tend to block everything else out at this point. I really need a cup of coffee to get into gear in the morning. It is the only way that I can get in harmony with my tasks and feel like I have a grip on things.
I think that it is really just a matter of perspective since I am one that puts high emphasis on things that make me happy. This is definitely one of them since it lets me get things done. A lot of people try and tell me that it is in my head. But I understand how caffeine works so they can't really tell me it is a placebo effect.
There are so many things you can learn about coffee, and the way it is made. I was cold brewing for a long time. And I can tell you, the effect the coffee has on me when it was cold brewed is different when it has cooked.
Everyones tastes vary.
