This sounds like a great/easy recipe. I know a number of people using coffee to marinade/slow cook in, I need to try it.

At 8 hours on high, even a neck roast will be a nice shredded mass.. nice and gravy like, if that's what you are going for. Kelly, please correct me if yours turns out different, maybe the high on my crockpot is just higher.. it does go to 11.

If you cube the neck roast and cook it less (maybe 6 hours), or cook it on low, the meat should hold its form better if you are looking for more stew like chunks of meat.

Just giving some options here, as there is NO way you can cook a roast wrong in the crockpot. Well, as long as you err on longer cook times. And have enough liquid. Ok, I guess it IS possible to cook it wrong!
