Moreover, defects in espresso brewing can result in inconsistent extraction, leading to imbalanced and unappealing espresso shots.
Impact of Defects
Defects in coffee beans can significantly alter the flavor, impacting the aroma and taste of the final brew. Understanding the impact of defects is crucial for ensuring quality control in coffee production.
For instance, the presence of defects such as mold, fermentation, or insect damage can lead to off-flavors in the coffee. Moldy beans can result in musty or earthy tastes, while fermented beans may produce sour or vinegary notes. Insect-damaged beans can introduce a range of undesirable flavors, including bitterness and astringency.
Remedying Defects Through Sorting and Processing
By carefully sorting and processing Robusta coffee beans, you can effectively remedy defects and ensure high quality in the final product. The following sorting techniques and processing methods are crucial for addressing defects and enhancing the overall quality of Robusta coffee beans:
