Espresso doesn't hide anything. It's a small, concentrated shot, so every flaw in a bean and every strength gets pulled straight into the cup. That's why picking the right beans matters more here than with almost any other brew method.
Why roast level matters most
Medium-dark to dark roasts tend to work best for espresso, and there's a real reason for that beyond tradition. Darker roasts develop more caramelised sugars and bittersweet, chocolatey notes that cut through milk and hold their own in a short, intense shot. They're also a bit more forgiving if your grind or extraction time is slightly off. Our Ascent roast was built with exactly this in mind, dark chocolate, molasses, and caramel notes that come through whether you're drinking it straight or with milk.
Origin still matters
Even in a dark roast, origin shapes the final cup. Ascent is built on the same Brazil, El Salvador, and India origins as Peak, just taken further in the roast, and it's grown above 1,500 metres like every Altura bean. That altitude is a big part of why the flavour holds together instead of just tasting burnt. If you want the full explanation of why altitude matters so much, we cover it in what speciality coffee actually means.
Freshness matters even more for espresso
Espresso shows staleness faster than almost any other brew method. Stale beans pull flat, thin shots with barely any crema. That's a big reason we roast to order rather than sitting on stock, the fresher the bean, the better your shot is going to look and taste.
Grind size and dose
A consistent, fine grind is non-negotiable for espresso, a decent burr grinder will do more for your shots than almost any other upgrade. As a starting point, aim for around 18 to 20g of coffee for a double shot, pulled over roughly 25 to 30 seconds.
Do you have to use a dark roast?
Not necessarily. Plenty of people pull excellent espresso with a medium roast like Peak, especially if they want a brighter, more clarity-forward shot in a flat white or cappuccino. Dark roast is the safer, more classic choice, but it comes down to what you like drinking.
Frequently asked questions
Is dark roast always best for espresso?
Not always, but it's the safer choice. Dark roasts tend to be more forgiving and produce the bittersweet, chocolatey notes people expect from espresso, though medium roasts can work well too if you prefer a brighter shot.
Can I make espresso without a machine?
You can get close with a Moka pot, which uses steam pressure to produce a strong, concentrated coffee. It's not identical to a true espresso shot, but it's a solid alternative if you don't have a machine.
How much coffee should I use for a double shot?
Around 18 to 20g of coffee is a good starting point for a double shot, pulled over about 25 to 30 seconds. Adjust from there based on taste.
