Fazenda Santuario Sul is a 120-hectare farm, 80 hectares of which are planted in coffee. It's owned by Luiz Paulo Dias Pereira Filho, who is a fourth-generation coffee farmer and a cofounder of CarmoCoffees. Luiz Paulo is very curious about innovation through varieties and processing experiments, and he uses Santuario Sul as a kind of "test" farm for some of his idea.
Among the 30 varieties and cultivars grown there (which include Gesha) is this heirloom Ethiopian type called Yirgacheff, named for the region from which it likely came. The heirloom varieties and very high altitude contribute to the exceptional quality of the farm's coffee.
