Embarking on the journey to perfect your coffee brewing experience? The medium-coarse grind size strikes a delicate balance, offering a rich and balanced flavor that's neither too bold nor too weak. This guide will walk you through the nuances of medium-coarse grind size, its impact on brewing, and how to achieve the perfect cup every time.
Overview & Background
The grind size of your coffee beans is one of the most critical factors affecting the taste and aroma of your final product. Medium-coarse grind size, often likened to the texture of sand, is ideal for brewing methods that require contact with water for a moderate amount of time. This grind size is perfect for drip coffee makers, pour-over setups like Chemex or V60, and even cold brew, as it allows for a good balance of extraction without over-extraction, which can lead to bitterness.

Preparing Medium-Course Grind Size
- Select Your Grind Size: Use a burr grinder to achieve a consistent medium-coarse grind. Aim for a grind size that resembles small sand particles.
- Measure Your Coffee: For every 256g of water, use 16g to 18g of coffee beans.
- Preheat Your Equipment: Rinse your filter and preheat your carafe with hot water to maintain the ideal brewing temperature.
- Brewing Process:
- Add the coffee grounds to your filter and pour a small amount of hot water over them to dampen them and release any gases.
- Wait 30 seconds, then slowly pour the remainder of the water over the grounds, making sure to distribute it evenly.
- Let the coffee brew for 4-5 minutes.
