Medium Roast Grind Size: The Goldilocks of Coffee Brewing

Discover the perfect balance between boldness and subtlety with medium roast coffee, ideal for French Press or Aeropress brewing. This guide will walk you through the nuances of medium grind size, ensuring your cup is neither too bitter nor too weak.

Overview & Background

Medium roast coffee strikes a middle ground between the rich, dark flavors of a full roast and the lighter, more acidic notes of a light roast. It's a versatile choice that pairs well with a variety of brewing methods, offering a robust yet approachable flavor profile. Medium grind size is crucial for methods that require a coarse grind, such as French Press, where it allows for a balanced extraction without overwhelming the palate.

Key Brewing Parameters / Specs

• Brew Time: 4-5 minutes for French Press, 2 minutes for Aeropress

Step-by-Step Guide for French Press

1. Place 40 grams of medium grind coffee into the French Press.
2. Slowly pour 640 grams of hot water over the coffee, making sure to saturate all grounds evenly.

Pro Tips & Common Mistakes

• Consistency: Use a burr grinder for consistent grind size. Inconsistent grinding can lead to uneven extraction.
• Temperature: Avoid water that is too hot, as it can extract bitter compounds. Aim for 92°C - 96°C.
• Over-extraction: Don't let the coffee sit in the French Press for too long, as it can become bitter. Aim for a 4-5 minute steep time.
