Günter Coffee Roasters is a specialty roaster based in Freiburg im Breisgau, Germany, founded in 2018 by Aurore Ceretta, Mats Weller, and Philip Weller. The founders first opened Café Marcel in Freiburg’s Stadtgarten in 2014; the roastery grew out of that venue when they decided to roast coffee to their own standards.

- Aurore Ceretta: World Cup Tasters Championship runner-up 2024 (Chicago). Two-time German Cup Tasting Champion (2023 Bremen, 2024 Frankfurt).

Roasting style
Günter emphasises precision light-to-medium roasting that reveals the natural flavours of each origin. The founders explicitly avoid the dominant roast-driven aromas that come from darker or longer roasts. Weekly roasting cycles ensure freshness. Every roast batch goes through a weekly cupping quality-control session.
Roast degree uses a 5-point scale (■□□□□ to ■■■■■). Most single-origin filter coffees are rated 1–2/5 (very light); espresso blends range from 3–4/5. This light-roast orientation aligns well with Kaiserblick’s filter roast development programme.
Sourcing philosophy
Green coffee is sourced via selected import partners who are committed to specialty quality and supply chain transparency. Named importers/trading partners visible in the product pages:
- Somaho / Vanía Nzeyimana — Rwanda sourcing partner (People’s Farm lots from Kivubelt Coffee / Murundo Washing Station, Kivusee region)
- DDC Kaffee — Colombia sourcing partner (referenced in blog)
For some origins Günter sources directly from farms. The site states long-term farmer relationships are a priority. No ACE or Cup of Excellence involvement is evident.
EU organic certification
Günter holds DE-ÖKO-007 (German/EU organic certification). Several products carry the Bio label (Toulouse, Peru Lima, Marcello Sweet, Marcello Strong). However, not all products are organic — single-origin coffees from Rwanda, Ethiopia, Uganda, and Costa Rica appear without organic labelling. This suggests EU organic certification is not a universal requirement for their green coffee sourcing — it applies selectively. This is a more favourable situation than Coffee Pirates Vienna, which requires EU organic for its entire catalogue. Verify this interpretation before outreach.
Wholesale
Günter supplies restaurants, cafés, and offices with specialty coffee. The wholesale page features testimonials from Freiburg-area café operators (Café Norso, Café Alma, Au contraire). Enquiry is via a contact form; no public price list. The offer includes professional barista training and equipment consulting.
Fit for Kaiserblick
HIGH fit. Key factors:
- No El Salvador — clean slate: No current or recently visible Salvadoran coffees. No competing supplier relationship to navigate. An open opportunity.
- Double German Roasting Champion 2024+2025: This makes Günter one of the most credentialed and quality-focused roasters in Germany. They actively seek outstanding coffees to showcase their craft.
- Elite tasting skills: Aurore Ceretta’s World Cup Tasters runner-up title and Phillip’s roasting championships mean this team will evaluate and appreciate nuanced terroir flavours — exactly what Apaneca-Ilamatepec high-altitude lots offer.
- Light roast / filter-forward: Directly aligned with Kaiserblick’s roast profile development for micro-lot filter coffees.
- EU organic partial fit: Günter is organic-certified and sells Bio products, but does not require all sourced coffees to be organic. Kaiserblick’s pending organic certification is not necessarily a blocking issue — but organic lots would command stronger positioning.
- Named-importer sourcing model: Günter uses importers for at least some origins. Kaiserblick may need to approach via an established EU importer (e.g. Trabocca, Nordic Approach, Cafe Imports) or pitch direct. Their stated interest in “some direct-from-farm” sourcing leaves a door open.
- SCA member: Attends specialty events; WoC Brussels is a natural touchpoint.
- Small roastery (15 kg Giesen): Volume per origin is modest — manageable lot sizes for Kaiserblick’s micro-lot programme.
- Champions edition product line: At €159/kg retail, they have demonstrated willingness to feature ultra-premium lots. A standout competition or auction lot from Kaiserblick could fit this tier.
WoC Brussels 2026 (June 25–27): As a double German Roasting Champion, Philip Weller is a plausible WoC attendee and competition participant. Priority target at the show.
Outreach angle: Lead with the double-champion hook — “We’d love to bring an El Salvador lot to a German Röstmeister.” Frame around terroir and precision: Apaneca-Ilamatepec altitude, variety diversity (Bourbon, Pacamara), and Kaiserblick’s own processing precision align naturally with their cupping-driven quality culture. Offer cupping samples well before WoC so Philip can evaluate with time. If Kaiserblick has EU organic-certified lots by then, lead with those for stronger fit.
