Duman is a variety of glutinous rice or malagkit grown only in Sta. Rita (Brgys Sta. Monica and San Agustin). Planting begins in June and harvest is in November when the cool air keeps the rice kernels fall off. The prized duman are the young greenish kernels that stay on the stalks. The way to get the duman is to shake the stalks. The greenish grains are gathered, watered and toasted for two hours. The grain is pounded the winnowed to separate chaff from grain. Unlike the regular rice variety, which can be planted and harvested three times a year, duman can only be harvested in the coll air of November and December.
