Basic Coffee Terms You Should Know

Grind Size (One of the Most Important Factors)

Grind size refers to how fine or coarse your coffee grounds are.

Why it matters:
Grind size directly affects how your coffee tastes.

  • Too fine → bitter, over-extracted coffee
  • Too coarse → weak, watery coffee

💡 Think of grind size as controlling how fast water pulls flavor from the coffee.

Different brewing methods require different grind sizes:

  • Espresso → very fine
  • Drip coffee → medium
  • French press → coarse

Coffee-to-Water Ratio (The Secret to Consistent Coffee)

The ratio is how much coffee you use compared to water.

Example:
A common ratio is 1:16 (1 part coffee to 16 parts water)

Why it matters:

  • More coffee = stronger, richer flavor
  • More water = lighter, weaker flavor

💡 If your coffee tastes too weak or too strong, adjusting your ratio is often the easiest fix.


Brew Strength vs. Caffeine Strength

These two are often confused.

  • Brew strength = how strong your coffee tastes
  • Caffeine content = how much caffeine is actually in it

A strong-tasting coffee isn’t always higher in caffeine.


Espresso Vocabulary Explained

Espresso (The Base of Most Coffee Shop Drinks)

Espresso is a concentrated coffee made by forcing hot water through finely ground coffee under pressure.

It’s used to make:

  • lattes
  • cappuccinos
  • Americanos
  • iced coffee drinks

💡 Most coffee shop drinks start with espresso shots.


Tamp (A Small Step That Makes a Big Difference)

Tamping is when you press coffee grounds evenly into the espresso machine.

Why it matters:

  • Ensures even water flow
  • Prevents weak or bitter espresso

💡 Think of tamping as creating a smooth, even surface for water to pass through.

Uneven tamp = uneven extraction = bad-tasting espresso


Extraction (Where Flavor Comes From)

Extraction is the process of pulling flavor out of coffee grounds.

The goal is balance:

  • Pull the good flavors
  • Avoid the bitter or sour ones

💡 Extraction is what actually determines how your coffee tastes.

  • Over-extracted → bitter
  • Under-extracted → sour

Shot (Espresso Serving Size)

A “shot” refers to a serving of espresso.

  • Single shot → about 1 oz
  • Double shot → about 2 oz

Most coffee drinks use double shots as the standard.


Crema (The Golden Layer on Espresso)

Crema is the light, foamy layer that sits on top of a fresh espresso shot.

Why it matters:

  • Indicates freshness and proper extraction
  • Adds texture and flavor

💡 A good espresso shot usually has a rich, golden crema on top.


Common Coffee Mistakes (And Easy Fixes)

1.) Mistake: Using the Wrong Grind Size

✔ Fix: Adjust your grind based on your brewing method


2.) Mistake: Ignoring Coffee-to-Water Ratio

✔ Fix: Start with a standard ratio (like 1:16) and adjust to taste


3.) Mistake: Not Tamping Properly (Espresso)

✔ Fix: Apply even pressure when tamping—this improves consistency


4.) Mistake: Brewing Time Is Off

✔ Fix: Pay attention to brew time—over or under brewing changes flavor

You’ll be able to:
