Coffee Maker - Chemex

Choosing the right coffee grind is crucial to achieving the perfect cup of coffee, as the size of the coffee grounds affects brewing time and flavor extraction. Here’s a guide to the different coffee grinds and their specific uses:

1. Grinding into Grains

• Description : Whole bean coffee is simply unground coffee. It is sold as whole beans and should be ground just before use to ensure freshness and flavor retention.
• Usage : Suitable for all preparation methods, but requires a coffee grinder to achieve the desired grind.

2. Espresso grind

• Description : The espresso grind is fine, almost like powdered sugar. This fineness allows for a fast and intense extraction under high pressure.
• Usage : Specifically for espresso machines. The high pressure of these machines requires a fine grind for optimal extraction in 25 to 30 seconds.

3. Italian Grind (or Fine Grind)

• Description : The Italian grind is slightly coarser than the espresso grind. It is still fine, but with a slightly more granular texture.
• Use : Used for Italian coffee makers (Moka). These coffee makers use pressure but not as much as espresso machines, hence a slightly less fine grind.

4. Grinding Filter

• Description : Filter grind is medium consistency, similar to granulated sugar. It allows for a slower extraction than espresso.
• Use : Suitable for filter coffee makers, such as drip machines or manual filters (V60, Chemex type). The particle size allows for a slow infusion that extracts aromas without bitterness.

5. Piston Grind (or Coarse Grind)

• Description : The piston grind is coarse, with clearly visible coffee particles and a texture similar to coarse salt.
• Use : Used for French Press coffee makers. The coarse grind prevents particles from passing through the coffee maker's metal filter, allowing for a long infusion that develops aromas without creating sediment.

Tips for Grinding

• Coffee grinder : Investing in a good coffee grinder, preferably one with burrs, allows you to obtain a uniform grind and easily adjust the particle size depending on the preparation method.
• Freshness : Grind the coffee just before preparing it to preserve all its freshness and aromas.
