"Pollination Experiment" - SL28xGeisha Experiment Set by POMA Coffee Research

It is commonly known that better pollination results in better fruit set and yields. However, pollination is a fundamental yet often overlooked factor influencing coffee quality.

In this re-release of this experiment, POMA investigated the influence of cross-varietal pollination on the quality of SL28 for year-on-year validation. Specifically, they examined whether the identity of the pollen donor (SL28/self-pollination vs. Geisha/cross-varietal pollination) consistently could impact sensory attributes and chemical composition of the resulting seeds to confirm that last years’ results were not by chance or random. 

 

Inside the set: you will find the two versions of the SL28. The first is the self-pollinated version (SL28 x SL28) showcasing a typical profile of this variety with pronounced blackcurrant and fruity aromas, while the second one is cross-pollinated with Geisha (SL28 x Geisha), producing a coffee with a more complex aroma profile, with heady florals, citrus, and currants.
