We do not, however it is easy to use a Keurig machine with your own coffee. Simply get a "My K-Cup" or other personal filter for the Keurig and use your own grounds!
I have personally discovered that filling a "My K-Cup" filter with 2/3rd fine ground fresh coffee, then brewing the smallest size cup provides bursting flavor and aroma. The key is trial and error with the fineness of the grounds.
For example, taking Annick's Classic Blend (which I enjoy daily, and never tire of) in a bag that comes ground from the roaster, then put that in my grinder and grind for another 5 seconds to reduce it even a bit finer, provides for me, the best flavor in a My K-Cup.
On another note, if you like to press your coffee, which I also enjoy, order whole bean coffee, then grind to a consistency that is a bit more coarse than you'd use in a filter basket. Some experts suggest that you should grind your coffee to the consistency of fine bread crumbs if you are going to press.
Therefore, take a bag of our pre-ground coffee, then grind a bit finer for My K-Cup, or use whole bean and grind a bit coarser than for a drip brewer if you'd like to press your coffee (French Press).
You may find your liking different and it is always up to your taste and preferences.
