For the discerning espresso enthusiast, the choice of filter basket is paramount, often overlooked, yet profoundly impactful. IMS, a name synonymous with precision, offers their Competition Convex Nanotech basket as a potential keystone for superior extraction. This is not merely a receptacle for ground coffee; it’s an engineered component designed to optimize flow dynamics and flavor.
Technical Breakdown
- Design Profile: This IMS basket features a distinct convex bottom, specifically engineered to manage puck thickness and water dispersion, a departure from traditional flat-bottom designs.
- Nanotech Coating: The entire basket is treated with a durable Nanotech coating. This hydrophobic surface actively repels coffee oils and water, significantly reducing particle adhesion and streamlining cleaning post-extraction.
- Big Bang Hole Pattern: The unique ‘Big Bang’ hole configuration is meticulously matched to the convex internal profile. It features an increased density of holes in the center, designed to compensate for the greater puck thickness there, ensuring uniform water distribution and preventing channeling.
- Capacity & Compatibility: Engineered for double espresso doses ranging from 20g to 24g, it demands a 58-58.5mm tamper for optimal puck preparation. Its 28mm height is designed for standard 58mm bottomless portafilters, ensuring proper clearance and seating.
The Real-wold Performance
In practical application, the IMS Competition Convex Nanotech basket delivers a noticeably refined extraction. The enhanced water flow through the puck’s center, due to the Big Bang pattern and convex profile, reliably translates to a more balanced and complex cup. Users will observe an appreciable enhancement in perceived sweetness and a richer, more integrated body, often leading to a denser, more uniform crema. The Nanotech coating genuinely simplifies post-shot cleanup, with grounds rinsing away effortlessly, contributing to consistent temperature stability across multiple extractions.
Who is this for?
This basket is unequivocally for the home barista meticulously pairing high-end grinders with premium beans, seeking consistent, analytical control over their espresso extraction.
