Espresso is simple. It's just hot water going through coffee. If your coffee tastes sour, bitter, or like it's taken a personal stance against you, there's a good chance the grind is involved. Getting consistently good espresso isn't about luck. It's about making small adjustments and only changing one thing at a time.
Start With Consistency
Before you reach for the grinder, make sure you're giving yourself a consistent starting point.
As a rough guide, we're aiming for:
• 18g of coffee in
• 36g of espresso out
• In 30-35 seconds
Not 17-ish. Not "that'll do." The more consistent your recipe is, the easier it becomes to understand what your coffee is telling you.
Tamping Doesn't Need To Be Dramatic
Once you've dosed your coffee, it's time to tamp. A firm, level tamp is all you're after. You don't need to punish the coffee.
Watch The Shot
When you start your extraction, don't just look at the timer. Watch the coffee. A good espresso will usually begin dripping after a few seconds before settling into a steady, even flow. Think warm honey. Not a garden hose.
What Your Coffee Is Trying To Tell You
If your shot runs too quickly, the water is moving through the coffee too easily. The result is often a sour, thin or under-extracted espresso. Try making your grind a little finer. If your shot runs too slowly, the water struggles to move through the coffee. That can leave you with something bitter, dry or over-extracted. Try making your grind a little coarser. The goal isn't to make huge changes. One small adjustment at a time is usually all you need.
Your Grinder Is Your Steering Wheel
Whether your grinder is built into your Breville, sitting beside it, or handled by your local roaster, grind size has one of the biggest impacts on flavour. Think of it as your steering wheel.
It gives you the control to respond to what you're tasting and make small adjustments until everything falls into place. The beans matter. The machine matters. But if your espresso isn't tasting quite right, we'd start with the grinder.
