Wonder if they considered featuring Altitude coffee, it's decent stuff and more closely related to the brand, in more ways than one.

No connection to the business, just a happy customer (of Altitude and Grind).

I used to cut open a bag of Union coffee then use in my Aeropress. Came out a lot better than stewed in a pot.
