Know Your Coffee Beans

Jan 23, 2024

Ever wondered why some coffee tastes light and fruity, while others hit like a bold, earthy punch?

It all comes down to the beans—where they’re grown, what kind they are, and how they’re blended and roasted.

If you’re aiming to become a true coffee aficionado, knowing your beans is the first step toward mastering the flavour in your cup.

Let’s break it down.

 

Meet the Bean MVPs: Arabica & Robusta

Most of the coffee we drink comes from two main bean types:

Arabica – The Smooth Classic
  • Origin: Highlands of Ethiopia
  • Grown In: Colombia, Brazil, Ethiopia, Costa Rica, and more
  • Flavour: Floral, fruity, nutty, even chocolatey
  • Caffeine: Lower
  • Fun Fact: These beans are oval with a curved crease and tend to be more acidic—great for bright, lively brews.

Arabica is the go-to for specialty coffee. If you’ve had a single-origin pour-over that tasted like citrus or berries? That was likely Arabica.

Robusta – The Bold Underdog
  • Origin: West and Central Africa
  • Grown In: Vietnam, Brazil, Indonesia
  • Flavour: Strong, bitter, earthy, woody
  • Caffeine: Almost double that of Arabica
  • Fun Fact: These beans are rounder and tougher—perfect for espresso blends and instant coffee.

Robusta may get a bad rap, but it’s the secret behind that rich crema on your morning espresso shot.

Honorable Mentions: Liberica & Excelsa

Though rare, Liberica and Excelsa beans bring wild, fruity, and smoky flavours to the table. They make up less than 2% of the global market but are prized by adventurous drinkers.

The Art of Blending: Building the Perfect Cup

Just like music needs different instruments to create harmony, coffee blends different beans for balanced, beautiful flavour.

Single-Origin Purity

These coffees come from one place and let you taste the unique vibe of that region—like citrusy Yirgacheffe from Ethiopia or nutty Colombian beans.

Espresso Blends

Often a mix of Arabica and Robusta. Arabica adds brightness, while Robusta adds depth and crema. The result? A bold, full-bodied espresso shot that hits just right.

Breakfast Blends

Lighter, smoother, and meant to ease you into the day. Think bright, clean, and easy-drinking.

Decaf Without Compromise

Decaf blends use special processes (like the Swiss Water Process) to remove caffeine without losing flavour. A good decaf still tastes like coffee, not cardboard.

 

Bean Science: What Makes a Brew Work

It’s not just about the bean—how you brew it matters too.

Grind Size
  • Fine for espresso
  • Medium for drip
  • Coarse for French press

Grind too fine for the wrong method, and you’ll get a bitter mess. Too coarse? Weak and watery.

Roast Level
  • Light roasts = more bean flavour, higher acidity
  • Dark roasts = bolder, roasted taste

Choose based on your brewing method and your taste preference.

Water Matters

Water is 98% of your coffee. If it tastes off, so will your brew. Use clean, filtered water at just the right temperature—usually between 195°F and 205°F.

 

Why This Matters to You

Learning to recognize bean types, flavour profiles, and brew methods lets you:

  • Choose better beans
  • Taste like a pro
  • Make a cup that fits your mood, every time

Whether you’re sipping a single-origin V60 or pulling a thick espresso shot, every cup tells a story. When you know the characters (the beans), the story gets even better.
