Two issues with the pods can cause this problem of grounds in your coffee and the top of the pod ruptured. I’ve found when using Dunkin’ pods (and another brand I can’t recall), the inside filter ruptures, allowing grounds to leak out into your coffee. Either the coffee is ground so fine that it clogs the pores of the filter and/or the filter is so fine and/or weak that pressure builds and it ruptures, sometimes causing the foil top to rupture as well, spewing grounds everywhere. The other problem I’ve encountered is a foil lid improperly sealed to the plastic cup. Pressure from inside the pod lifts the edge of the foil and creates a big mess.

With the Dunkin’ cups, if I limit them to a 10oz brew, I can get away with no problem most of the time.
