Tandem Coffee Roasters

Tandem Coffee Roasters is based in Portland, Maine, with two distinct retail locations: a Café and Roastery at 122 Anderson Street and a Coffee and Bakery at 742 Congress Street. The roaster focuses on single-origin coffees sourced from regions including Ecuador, Ethiopia, Peru, and Colombia, with offerings that highlight specific producers and processing methods such as honey processing. In addition to single-origin lots, Tandem offers house blends and instant coffee options. Customers can access a range of subscription tiers organized by region or roast profile, including African, South and Central American, and other curated selections. Beyond coffee, the company sells wearables, accessories, vinyl, and gift cards, and maintains a rewards program using a proprietary currency called Venkmans. The roaster also provides catering, wholesale, and technical services, and hosts public cuppings. Bakery online ordering is available daily for same-day pickup.
