Roasting Profile

Roasting Record for Guatemala La Serrania Geisha Natural
Roasting Record for Guatemala La Serrania Geisha Natural

The characteristics of Central American naturals are not as pronounced; the natural processing's fermentation and character are relatively subtle. It seems to be naturally processed in a way that embraces clean, floral, tea-like, aromatic attributes - highlighting the features of the Geisha variety.

For the next batch, I might try roasting with slightly increased gas pressure to achieve a more intense flavor profile.

The roasting profile was designed considering three factors: origin (Central America, Guatemala), processing method (Natural), and desired roast level (Medium Light). The profile was set with a medium gas pressure.

Roasting Profile

Several elements need modification in the profile. Though naturally processed, it is presumable that a washed processing was involved. The progression resembles a washed roast, and the cup character also shows nuances of a washed Geisha. Therefore, it seems appropriate to modify the profile to a washed-processing profile. The current profile is not adequate, showing signs of underdevelopment. In order to resolve this, a higher gas pressure supply is needed, along with a higher damper setting and lower charge temperature. I plan to refer to other Central and South American washed green coffee posts, proceed similarly, and confirm the profile after checking the cup. The roasting profile was designed considering three factors: origin (Central America, Panama), processing method (Natural), and desired roast level (Light). It was set with a medium gas pressure.

However, it seems necessary to proceed with a profile that forms a higher gas pressure.

Roasting Profile

There are elements in the sample profile that require modifications.
The roasting profile and cupping revealed the underdeveloped characteristics - low intensity of con aroma.
The sampled green coffee, [Bolivia Cusillo Java Natural], sampled as a weekly coffee, shows different aspects from the natural processing method. While Cusillo Java displays typical natural green coffee progression and taste, Los Rodriguez Geisha appears to require an early first crack temperature and rapid airflow, similar to a washed process.
Slightly increasing the heat (about 0.02~0.05kPa) and reducing the charge temperature (by about 20 degrees) might resolve the underdevelopment, allowing for more pronounced floral and fruity nuances.

The roasting profile was designed considering three factors: origin (Central America, Bolivia), processing method (Natural), and desired roast level (Medium Light). It was set to a medium size between profiles that form higher and lower heat supplies.
