Mastering Medium Roast Coffee: Grind Size & Brewing Guide

Medium roast coffee offers a balanced profile, striking a delicate balance between the boldness of dark roast and the lightness of light roast. However, achieving the perfect cup of medium roast coffee is more than just choosing the right beans; it's also about getting the grind size just right. The grind size impacts how well water extracts the flavors from the coffee grounds, and for medium roast, a precise grind size is key to unlocking its full potential.

Overview & Background

Medium roast coffee beans are roasted to a level that highlights their unique characteristics without overpowering them. This roast level is often preferred for its versatility, as it pairs well with a variety of brewing methods and can be enjoyed both on its own and in blends. The grind size plays a crucial role in how these beans perform, affecting the brewing time and the extraction of flavors.

Key Brewing Parameters / Specs

For medium roast coffee, the grind size should be slightly coarser than espresso grind but finer than French press grind. This middle ground helps in achieving optimal extraction without over-extraction or under-extraction.

• Grind Size: Medium-Fine to Medium
• Water Temperature: 92°C - 96°C (198°F - 205°F)
