"Another advantage of cold brewed coffee is that it stays fresh for much longer than hot coffee, which goes stale as it cools down, so you can have a keg on tap for a month without losing its flavor..."
A dubious claim followed by a non sequitur.
What the HECK are those briquettes? And they're going to grind that much coffee in that little thing? Really?
In all seriousness, why do people advertise brewing methods that they claim preserve so much wonderful flavor, and then showcase beans that don't have enough good flavor to start with, worth preserving?
