Quartermaine Coffee Roasters is a Rockville-based specialty coffee roaster that has been a staple of the Washington, D.C. metropolitan area since 1991. The company focuses on batch-roasting high-quality arabica beans, offering both a signature dark roast and a lighter 'Aromatica' roast profile. They operate a local retail presence alongside a wholesale division that distributes coffee across the East Coast. The company maintains a commitment to freshness by avoiding artificial vacuum packaging, instead prioritizing rapid distribution from their Maryland roasting facility. Their market position is defined by a long-standing reputation for quality and a direct, hands-on approach to sourcing and roasting that emphasizes the balance of body, acidity, and flavor.

These are examples recorded during editorial research. They are not a live product feed. The coffee, lot, price, and availability may have changed. We have not necessarily brewed these coffees ourselves.

External customer, cafe, marketplace, and class ratings are not comparable measures of the quality of an individual coffee. We do not convert them into original tasting scores or brand-wide star ratings. Our independent reviews are published separately after a coffee has actually been brewed and evaluated.
