On the Nyeri-Kirinyaga boarder lies the Gatina Coffee Factory. Together with four other factories; Kagumoini, Kiamabara, Kieni and Gathuga, Gatina belongs to the Mugaga Farmers Cooperative Society. Its membership currently stands at 681 farmers. Coffee is received, sorted, pulped, fermented and washed at the base of the hill at Gatina. It’s then pumped or carried to the highest corner of the hill for drying.
