SL34

What it is and what sets it apart: SL34 is a variety or species documented in specialty coffee. Kenyan selections (Scott Laboratories and later): famed for acidity and black fruit when AA/AB process and elevation align. Also known as SL-34. Reference genetics: Kenyan Arabica selections, including Scott Laboratories lines and resistant crosses.

Flavours in the cup: Citrus acidity, red fruit and often a slightly sturdier body than SL28 in Kenyan lots. Process (washed, natural, honey), elevation and roast can shift this guidance a lot.

Technical notes and growing zone: Usual zone and origins: Kenia. Guidance altitude: 1.600–2.000 m. Habit: Medium, vigorous shrub managed with pruning; exact form depends on the cultivar. Cultivation: Best at elevation with regular rainfall and fertile soils; manage rust and shade.

Usage tips: V60/Kalita filter often highlights fruit; for espresso, lower temp slightly if acidity feels sharp. In Cafesito, search the name with origin and process; compare lots before judging the variety.

Common mistakes: Crediting everything to variety and ignoring Kenyan process; buying “Kenya SL28” with no lot data; very short sour espresso.
