I work in maintenance at Massimo Zanetti Beverage Group, here in the swamp.
We make Chase & Sanborn, Hills Bros., MJB, Chock Full O' Nuts, Kirkland (Costco.), Master Chef (Walmart) and other various and sundry store brands. My favorite is the Kirkland 100% Columbian, brewed in my Krups espresso maker. It's a powerfull cup of coffee, not for the squeamish. Other folks at the plant who prefer a more mild cup like the MJB Hawaiian Blend which is 10% Kauai.
The fragrance inside the plant can be overwhelming. But lately we have been getting into the flavored coffees. Which is nice 'cuz one day the place will smell of French Vanilla, the next day Hazelnuts, etc.
