MHW Espresso Chilling Ball: 30mm - Smooth

MHW-3Bomber Espresso Chilling Ball: 30mm

The MHW Espresso Chilling Ball: 30mm is designed to instantly cool espresso as it’s extracted, locking in aroma and reducing bitterness. Perfect for precision brewing.

Preserve Aroma and Clarity During Espresso Extraction

Chilling espresso immediately after extraction helps preserve delicate aromatics and reduces the sharp bitterness caused by high-temperature oxidation. The MHW-3BOMBER Espresso Chilling Ball sits directly beneath the espresso stream, cooling it rapidly to deliver a smoother, more flavourful shot.

How It Works

The 30mm espresso chilling ball functions as a thermal sink. Pre-frozen before brewing, it sits in your cup under the portafilter spout. As espresso flows over the stainless steel surface, its temperature drops instantly. This preserves aroma compounds and enhances clarity, leading to a sweeter, more balanced cup.

How to Use

1. Freeze the chilling ball for 3–4 hours at -5°C to -18°C (ideal: -15°C).
2. Place it in your espresso cup before extraction.
3. Use a split spout for best results and align closely to the ball's centre.
4. Extract the full shot over the ball to maximise chilling.
5. After use, clean and return to freezer — ready in 20 minutes.

Maintenance & Cleaning

Rinse the ball after each use or wipe clean. Store it back in the freezer after drying. Do not use abrasive cleaners or expose to high heat outside of intended use.

Best Practices for Brewing

For espresso clarity, use the chilling ball in the centre of the stream. When preparing iced drinks like Americanos or iced lattes, extract the espresso fully over the chilling ball to reduce the temperature without altering the strength or body. Pair with light to medium roast coffees to highlight floral and fruity notes.
