MHW-3Bomber Moonstone Espresso Chilling Filter Cube: Silver

MHW Moonstone Espresso Chilling Filter Cube: Silver is a high-precision tin tool designed to enhance espresso and pour-over extractions through cooling, flavour refinement, and flow control. Its conical mirror-polished surface preserves crema, cools espresso efficiently, and elevates aroma clarity with every shot.

Chill, Clarify, and Control Your Espresso Extraction

The Moonstone chilling cube uses a 72° polished tin funnel and deep flow channels to retain crema and enhance aroma in espresso and pour-over brews. A 43mm arched contact surface and circular flow path smooths out your pour and disperses water evenly for cleaner, more refined extractions. This cooling tool offers baristas precision flow and flavour improvement without dilution, which is perfect for sensory testing or creative espresso service.

How the MHW Moonstone Works

• Step 1: Place the Moonstone chilling cube on your espresso cup or server.
• Step 2: Begin extraction—coffee flows over the tin funnel, cooling on contact.
• Step 3: Observe reduced splashing and more stable crema formation.
• Step 4: For pour-over, place the Moonstone beneath the filter (≤2cm distance recommended).
