Kambaa is one of the premiere factories under umbrella of the KTDA (Kenya Tea Development Authority -a state run corporation). Each factory in the KTDA relies on the �small holder� (small individual family farming unit) to provide the green leaf for the making of loose leaf black tea. Within the KTDA there are 150,000 small holders supplying green leaf to 39 factories scattered throughout the tea growing districts of Kenya. Despite such a diverse supply of green leaf to the various factories there is very rigid quality control mechanisms in place, which ensure that farmers tender top quality produce. Kambaa is consistently within the top 4 quality tea estates of the KTDA and indeed Kenya.
