Tea was first grown in the area in early 1960's. Nyankoba is the oldest Tea Factory in Kisii region. The construction work was commissioned on 14th May 1965 by Hon L. G. Sagini who was the Minister for Local Government. It was officially opened on 9th March 1966 by Hon. B. R. McKenzie the then Minister for Agriculture and Animal Husbandry. The factory serves 16,727 tea farmers who are also shareholders of the company and who have approximately 1827.7 Ha under tea. The clones grown include SFS/150, 31/8, 6/8,303/577,301/4,301/5 and BB 35,15/10.

The Factory is situated approximately 34.9 degrees East and 0.8 degrees South of the equator at 2160m above sea level. It is 340km North West of Nairobi, the capital city of Kenya and 130km South East of Kisumu, the lake side city. It is 25km from Kisii town on the Kisii - Sotik highway. Administratively, the factory is in the Rigoma ward of Masaba North sub-county in Nyamira county. The catchment has a rugged topography, characteristic of the famous Kisii highlands. Not far away are the Manga escarpments. The giant Gucha River cuts right across the area on its long journey to Lake Victoria. With its proximity to the Lake Victoria basin, the area receives well distributed rainfall through out the year.

Occasionally, the area experiences strong cold winds. When it rains, the area is prone to heavy thunder and lightening. Actually, the name “Nyankoba” is derived from the word “Enkoba” which means “thunder” in the local Gusii language. The soils are mainly alluvial which are deep i.e. more than six feet with a pH between 4.5 -6.5 and well drained. The vegetation cover consists of indigenous and exotic trees. Apart from tea, other crops are also grown including pyrethrum, maize, beans, potatoes, coffee and bananas& finger millet are trade mark crops for Kisii.
