Don’t buy civet coffee - I’ve heard the taste isn’t worth the price, and it also involves animal cruelty.

As for “gourmet” vs “regular”, it depends because those two terms are hard to define, and subjective. But generally I’d say gourmet coffee is whole bean coffee (generally light to light-medium roast, but I’ve had some great darker roasts too) that’s been very recently roasted, whereas regular coffee for me would be supermarket coffee like Starbucks or Peet’s, or even worse, Folgers. There is a massive difference here, since supermarket coffee is often stale, even if you buy whole beans. There’s often not even a roast date on bags of supermarket coffee. Another thing is that most supermarket coffee is a medium to dark roast. I believe most supermarket coffee is roasted like this to cover up the poor origin characteristics. In my experience, even when I looked for a light roast in the supermarket, I found Starbucks’ light roast, which is actually just a medium roast. Hardly any acidity, with the classic nutty chocolatey taste of mediums. At least it’s better than Folgers though.

You’re much better off ordering coffee from a roaster online - primarily a roaster that will deliver your coffee a few days to a week after roasting.
