Carmo de Minas sits in the south of Minas Gerais, high enough for coffee to ripen slowly and cool enough that winter frost is a real risk. Fazenda Sertão answers that with geography: 330 hectares planted on the tops of the hillsides, on slopes reaching 50%, where the cold air drains away instead of settling on the trees. The same exposure ripens the cherries evenly and keeps the canopy dry enough to hold fungal disease back. Altitudes run from 1,100 to 1,450 metres and the year averages 18 °C — the conditions behind the dense, sweet beans this farm is known for.
