Which ground coffee size is best?

Coffee grind sizes refer to the coarseness or fineness of the coffee particles obtained after grinding coffee beans. The grind size plays a crucial role in the coffee brewing process, as different brewing methods require specific grind sizes to achieve the desired flavour and extraction. Here are some common coffee grind sizes and the brewing methods they are typically used for:

Coffee for French Press, Cafetière, Cold Brew & Percolator

Grind Size: Coarse

Description: Coarse grind has larger coffee particles, similar to sea salt or rough sand.

Brewing Methods: French press, Cafetière, cold brew, percolator.

Coffee for Chemex, Clever Dripper, Cafe Solo Brewer

Grind Size: Medium-Coarse

Coffee for Turkish Coffee

It's important to match the grind size to the specific brewing method to optimize the extraction process. Using the correct grind size ensures that water passes through the coffee grounds at the appropriate rate, extracting the desired flavours and avoiding over-extraction or under-extraction.

Remember that the grind size can also be adjusted based on personal preference. For example, some espresso enthusiasts prefer a finer grind to achieve a richer flavour, while others may prefer a coarser grind for a milder taste. Experimenting with different grind sizes and brewing techniques can lead to discovering the perfect cup of coffee tailored to individual preferences.
