Introduction
In this article, we compare two recipes for brewing Kenya Kirimahiga coffee using the same IMS filter model, B702TFH24. The key difference lies in the filter coating: the first recipe uses a standard filter, while the second incorporates the Nanoquartz coating. By analyzing the results, we aim to highlight the impact of the Nanoquartz coating on the cup profile and brewing efficiency.
First Recipe: Standard Filter (B702TFH24)
Coffee Details
- Origin: Kenya
- Mill: Kirimahiga
- Producer: Smallholder farmers
- Region: Muranga
- Altitude: 2100 masl
- Varietal: Batian, SL28, Ruiru11
- Process: Washed
Recipe
- Filter: B702TFH24
- Grams in: 18
- Grams out: 38
- Seconds: 27
- TDS: 8.92
- Extraction Yield: 18.83%
Sensory Profile
- Aroma: 8
- Sweetness: 6
- Acidity: 4
- Bitterness: 1
- Aftertaste: 6
- Flavor Notes: Cocoa, Red Berry, Pink Grapefruit
Considerations
The cylindrical shape with a flat bottom of the IMS filter ensures optimal utilization of the coffee puck. This design facilitates drying and expulsion, contributing to a clean workflow. The resulting cup highlights a cocoa-forward profile with balanced red berry and pink grapefruit notes.
Second Recipe: Nanoquartz Coated Filter (B702TFH24NT)
Coffee Details
- Origin: Kenya
- Mill: Kirimahiga
- Producer: Smallholder farmers
- Region: Muranga
- Altitude: 2100 masl
- Varietal: Batian, SL28, Ruiru11
- Process: Washed
Recipe
- Filter: B702TFH24NT
- Grams in: 18
- Grams out: 38
- Seconds: 29
- TDS: 9.08
- Extraction Yield: 19.16%
Sensory Profile
- Aroma: 9
- Sweetness: 7
- Acidity: 5
- Bitterness: 1
- Aftertaste: 7
- Flavor Notes: Milk Chocolate, Raspberry, Strawberry Yoghurt, Caramel Finish
Considerations
The Nanoquartz coating elevates the brewing experience by enhancing the antibacterial properties and non-stick nature of the surface. This results in easier removal of used coffee grounds and simplified cleaning. In the cup, the Nanoquartz coating emphasizes sweetness, acidity, and flavor clarity, with a notably silkier body. The vibrant flavor notes, such as milk chocolate, raspberry, and strawberry yoghurt, are further accentuated, leading to a more refined and dynamic tasting experience. The rainbow effect characteristic of the Nanoquartz coating is temporary, but its benefits are permanent.
Comparison and Conclusions
The Nanoquartz-coated filter demonstrates clear advantages over the standard filter, particularly in terms of sensory enhancements and workflow efficiency. The second recipe achieved a higher TDS and extraction yield, showcasing a richer, more complex cup with elevated sweetness and acidity. While both filters provide a clean and consistent brewing process, the Nanoquartz coating significantly refines the flavor profile and body, making it a valuable tool for those seeking a superior coffee experience.
