Coffee People Jet Fuel K-Cups for Keurig Brewers (Pack of 50) [Amazon Frustration-Free Packaging]

Not undrinkable, but not great. I'm a fan of Starbucks-style deep, dark richness with a little bitter kick. This has the bitter, but it just tastes thin to me.

I haven't found a great dark K-cup yet. My favorite so far is Green Mountain Dark Magic, in case that helps you judge how you perceive my review.

I enjoy a strong bold k cup so that I can stretch the coffee to a mug. I have tried around a dozen k cups that have been given at least 4 stars and have found Jet Fuel to be my favorite. It is strong and has good flavor, but is not bitter like some of the others. I also enjoy Emiril's k cup.

I CAN'T GET ENOUGH OF THIS COFFEE. IF YOU ARE A REAL COFFEE DRINKER, LIKE MYSELF, THAN GO FOR IT.

If you're looking to upgrade from Donut Shop, Jet Fuel is a deep roast that retains Donut Shop's nutty flavor. IMHO Coffee People blends tend toward the weak side, and Jet Fuel follows the trend. I think of it as Puddle Jumper Fuel.

For a K-Cup equivalent to Starbucks' Sumatra or Gold Coast blends, I would recommend Timothy's Midnight Magic instead. Midnight Magic really is "jet fuel".
Timothy's World Coffee, Midnight Magic, Extra Bold for Keurig Brewers, 24-Count K-Cups (Pack of 2)

The Keurig machine is unbelievably convenient, but I find the majority of K-cups are simply weak and unpalatable. I always buy the coffees labeled "bold" as nothing else cuts it.

Jet Fuel is a decent cup of coffee. It's not quite the body of a drip brewer, but comes pretty close. Close enough that I'm not inclined to schlep out the drip brewer and spill coffee grounds on the counter and wait 10 minutes before I can have my wake up beverage.

One other thing - the cups are just loose in a big box, so you will want to have a basket or other container to put them in.
