Roasting in perpetuity: That will be the state of Coffeehouse NW owner Adam McGovern and old/new biz partner/Bluehour mixologist Eric Miller when the pair opens a coffee stand/roasting facility called Sterling Coffee Roasters in mid-December next to Sammy's Flowers and Trader Joe's on NW Glisan near 21st Avenue. Sterling will feature Portland's smallest commercial roasting machine (Pictured above) wherein McGovern will roast all of the shop's coffee in one-pound increments, each batch taking between 10 and 15 minutes. Miller says one employee will have to to work the roaster at all times just to keep the shop's Synesso espresso machine (which was purchased from Billy Wilson's Barista) fully stocked. Back at the original acclaimed coffee shop and food writer hangout Coffeehouse NW, McGovern will continue serving Stumptown coffee beans while showcasing one of several rotating Stumptown-roasted single-origin espressos. Like Heart and Extracto, Sterling is another entry in a wave of Portland coffee shops now roasting in-house.
