Mexico Talea de Castro (Ext. Fermentation)

Marty Lopes founded Roseline Coffee in Portland in 2012, starting with a 1.5 kilo Proaster and upgrading within a year as demand grew. A former coffee buyer at Barista PDX and Thomas Hammer Coffee Roasters, Lopes built the operation around precision, consistency, and a deep respect for the coffees themselves. Sourcing is driven by team consensus from blind cuppings rather than price lists, and the roastery maintains long standing relationships with farmers across Ethiopia, Kenya, Colombia, Guatemala, and Burundi. The name references Portland's Rose City identity and the roseline pattern in latte art, a nod to the intersection of craft and creativity that defines the brand. Roseline was named a finalist in the 2024 Sprudge Design Awards for both its roasting facility and its packaging.
