A tall Kenyan selection with exceptional cup potential at altitude, but highly susceptible to coffee berry disease.
SL34 was selected at Scott Agricultural Laboratories in Kenya from a single tree labelled French Mission. It has dark bronze shoot tips, large beans and exceptional cup potential, suited to high, well-watered sites. It is susceptible to berry disease, leaf rust and nematodes.
