MHW-3Bomber Pour Over Chilling Ball: 42mm
The MHW Pour Over Chilling Ball: 42mm is designed for precision cooling during manual brewing. It enhances clarity, boosts aroma retention, and reduces over-extraction in pour-over coffee.
Control Brew Temperature for Cleaner Pour-Over Flavours
The 42mm chilling ball sits just below the dripper during extraction. Acting as a thermal sink, it rapidly cools the coffee at its initial contact, preserving delicate aromas and reducing harsh over-extraction. It's engineered specifically for iced or high-clarity brews.
How It Works
Place the chilling ball below your V60 or egg-shaped dripper, maintaining a ~5mm gap from the coffee flow. Use it during the first 40% of brew time, when most aromatics are released. The concave surface design prolongs contact, enhancing clarity and brightness.
