Rösttrommel

What Rösttrommel does

Rösttrommel Kaffeerösterei is a Nuremberg-based specialty coffee roastery founded in 2010, operating a vertically integrated model that combines green-bean sourcing, in-house roasting, retail cafés, e-commerce, wholesale supply, an in-house coffee school, and an adjacent ceramics brand. The firm sources green coffee through a mix of specialty importers (Cafe Imports, InterAmerican Coffee, Forest Coffee) and direct-trade relationships with named producers in Colombia and Nicaragua, including Carolina Padilla, Erwin Mierisch, Romulox Andrade, and Juan Saldarriaga, and holds DE-ÖKO-001 organic certification for its BIO/Organic line. Roasting is conducted on Giesen drum roasters with profiles managed in Cropster, indicating mid-volume specialty hardware paired with industry-standard process-control software rather than proprietary technology.

The company serves both end consumers (D2C online orders, four company-owned cafés in the Nuremberg metropolitan area) and business customers (horeca wholesale, corporate gifting). Its assortment spans single-origin espresso and filter coffees (€9.90–€34.90 per 250g), co-infused SKUs, accessories and brewing equipment ranging from €7.90 to €3,980, and a Kaffeeschule education program with courses priced €49–€690. Hartmud Studio, an in-house ceramics subsidiary founded in 2017, manufactures mugs, brewing vessels, and tableware that are co-sold with Rösttrommel coffee, creating a curated lifestyle ecosystem around the core roastery business.

Revenue mechanics are diversified across product sales (coffee, equipment, ceramics), café operations, education, and B2B wholesale, but the firm is privately held with no disclosed revenue, headcount trajectory, or funding events, limiting visibility into unit economics and growth rate. Geographic focus is explicitly DACH (Germany, Austria, Switzerland), and the brand is positioned around transparent direct-trade sourcing and certified-organic credentials rather than technology differentiation.
