There IS a difference in supermarket brands

Surefine (Mac's Market house brand) 100% Colombian coffee tastes better than Shaw's house brand 100% Colombian coffee.  Was in Shaw's the other day and picked up a can of their stuff by mistake.  Bad idea, it was harsh and bitter.  Even youngest son commented on how bad it was.  Whereas the Surefine at $4 and change a can tastes as good as jazzier coffees going for as much as $9 a can.
