Previous Auctions

Los Favoritos with Fincas Mierisch

Our private auction “Los Favorites” was born in 2013 as an initiative to show the world the exquisiteness and allure of the coffees produced by Fincas Mierisch in Nicaragua. Characterized by cultivating different varieties and experimenting with distinct post-harvest processes, the lots are chosen from the cream of the crop of the family ‘s eight farms. Quality is not a coincidence. Quality is hard work that is built every day. We are a generation that is passionate about coffee and our mission is always focused on continuous improvement, innovation, and sustainability.
