Your espresso tastes like disappointment. Not because you’re hopeless. Because you’re making the same seven mistakes everyone makes when they start pulling shots at home.
The best coffee beans for espresso won’t save you if you’re getting the basics wrong. But fix these mistakes and suddenly your kitchen machine starts producing shots that rival the stuff you pay £4 for in town.
Let’s fix it.
This is the big one. The murder scene. The crime against caffeine.
Supermarket beans sit on shelves for weeks. Sometimes months. By the time they hit your grinder, they’ve lost most of their oils, aromatics, and any chance of producing decent crema.
Freshly roasted coffee beans are the difference between “meh” espresso and “bloody hell, I made this?” espresso.
The fix: Buy beans roasted to order. Not roasted-then-stored. Roasted after you click buy. Check the roast date. If it’s more than two weeks old, you’re already losing flavour.
We roast after you order. Your beans arrive days old, not months old. That’s the standard.
Too coarse and your espresso runs fast. Tastes weak. Watery. Sad.
Too fine and your machine chokes. Nothing comes out. Or it drips like a broken tap and tastes burnt.
Espresso grind needs to be fine. But not powder. Think caster sugar, not icing sugar.
The fix: Invest in a decent burr grinder. Adjust in tiny increments. Your target extraction time is 25-30 seconds for a double shot. If it’s faster, grind finer. If it’s slower, grind coarser.
Dial it in. Every bean is different. Every machine is different. There’s no magic number.
Your espresso is 90% water. If your water tastes like chlorine or limescale, your espresso will too.
Hard water clogs your machine. Soft water tastes flat. You need the Goldilocks zone.
The fix: Use filtered water. Not distilled. Not straight from the tap (unless you’re blessed with great water). A simple carbon filter jug does the job.
If your kettle has limescale, your espresso machine does too. Descale regularly. Your machine will thank you. Your taste buds will thank you.
Not all beans work for espresso. Light roasts taste sour and thin under pressure. They’re built for pour-over, not espresso.
The best coffee beans for espresso are darker roasts. Medium-dark minimum. Full-bodied. Oils visible on the bean. Built to handle 9 bars of pressure without falling apart.
The fix: Look for espresso-specific blends or single origins labelled for espresso. At Roast My Bean, our Filthy and Ferocious profiles are espresso weapons.
Filthy is bold, heavy-hitting, zero apologies. Think dark chocolate, toffee, serious body.
Ferocious is the wake-up call you didn’t ask for but absolutely needed. High caffeine. Maximum impact. Monday morning survival in a cup.
Both work beautifully under pressure. Both deliver crema. Both taste like you know what you’re doing.
“I just eyeball it.”
No. Stop. Espresso is precise. One gram makes a difference.
Guessing your dose means inconsistent shots. Sometimes great. Usually not. You’ll never know what went right or wrong because you didn’t measure.
The fix: Buy cheap kitchen scales. Weigh your dose. Standard is 18g in, 36g out (1:2 ratio).
Adjust to taste. Want it stronger? Go 1:1.5. Want it longer? Go 1:2.5. But write it down. Dial it in. Repeat what works.
Consistency beats luck every time.
Tamping too light and water finds the path of least resistance. Channels through the puck. Tastes weak and bitter at the same time (impressive, really).
Tamping unevenly creates the same problem. Water flows where it’s easiest. Half your puck gets over-extracted. Half gets under-extracted. The result? Rubbish espresso.
The fix: Tamp firm. Tamp level. Apply about 15kg of pressure (push until you can’t push anymore without straining).
Use a flat tamper that fits your basket. Keep it level. Give it a light twist to polish the surface.
Distribute your grounds evenly before tamping. Tap the portafilter. Use a distribution tool if you’re fancy. Just make sure it’s level before you press.
Espresso extracts between 90-96°C. If your machine isn’t up to temperature, your shot will be sour, under-extracted, disappointing.
Pulling a shot immediately after turning on your machine is a rookie error. The boiler might be ready. The group head isn’t.
The fix: Heat your machine for at least 15 minutes before pulling a shot. Run a blank shot through the group head to warm the portafilter and basket.
Preheat your cup. Nobody wants espresso going cold in a freezing mug.
If your shot tastes sour, your water is too cold or your extraction is too fast. If it tastes burnt and bitter, you’ve over-extracted or your water is too hot.
Dial. It. In.
