You’ve got the beans. You’ve got the machine. You press the button—and you wait.
But here’s the real question: Is your espresso shot actually well-extracted?
Most people assume that once coffee flows into the cup, the job is done. But the quality of your espresso comes down to something critical: extraction. And when done wrong, it can make your cup sour, bitter, or just plain weak.
At Zuma Coffee, we’re here to help you go from guesswork to greatness with your coffee game. Let’s break down the three types of espresso extraction—and how to know if you’ve nailed it.
Under Extraction
Taste: Sour, acidic, weak Body: Watery Crema: White, thin, not persistent Flow: Fast – around 20 seconds
If your espresso tastes sharp and underwhelming, chances are you’re under-extracting. The water didn’t have enough time to pull the full range of flavor from the grounds. It’s like stopping a great story at chapter one.
Tip: Try a finer grind or increase your brew time slightly to get more depth.
Perfect Extraction
Taste: Balanced, sweet Body: Medium Crema: Hazelnut brown, thick Flow: Ideal – 20 to 30 seconds
This is where the magic happens. A perfectly extracted shot has a rich, full-bodied taste with a sweet balance and thick crema on top. It hits all the right notes and gives you that signature Zuma-quality experience.
Pro tip: Zuma Coffee beans are roasted to help you hit this sweet spot with ease.
Over Extraction
Taste: Bitter, strong Body: Heavy, syrupy Crema: Dark brown Flow: Slow – 30+ seconds
If your espresso is overpowering and bitter, it’s likely over-extracted. This happens when hot water stays in contact with the grounds too long, pulling out undesirable, harsh compounds.
Tip: Use a coarser grind or reduce your brew time for a smoother shot.
