I have a high end espresso machine and I can honestly say one of the best cups I had recently was Foldgers at a friend's house
For my daily brew, I've actually transitioned over this summer to a Hario cold brew bottle. It's the size of a wine bottle, I cut up a few k-cups from the office into it each day before I go home and put it in the office fridge. The next day I have cold brew that I can keep boring into a whisky glass that I drink from all day.
