What to check first

Brewer type and filter type

Your espresso machine and its portafilter basket are the heart of the operation. Different baskets have different hole sizes and shapes. This affects how the espresso flows. A good basket is crucial for even extraction.

Water quality and temperature

Espresso is mostly water. If your water tastes bad, your espresso will taste bad. Filtered water is usually best. For espresso, water temperature typically runs between 195°F and 205°F. Too hot or too cold, and you’re chasing your tail.

Grind size and coffee freshness

This is huge for espresso. You need a fine, consistent grind. Think table salt, maybe a bit finer. Freshly roasted beans are a must. Aim to use beans within a few weeks of their roast date. Old beans lose their magic.

Freshly roasted beans are a must for great espresso. For the best results, consider using high-quality espresso beans like these.

Coffee-to-water ratio

This is often called the “brew ratio.” A common starting point for espresso is 1:2. That means for every gram of dry coffee grounds, you get two grams of liquid espresso. So, 18g of coffee in, 36g of espresso out.

Cleanliness/descale status

Old coffee oils and mineral buildup are the enemy. Clean your espresso machine regularly. Descale it according to the manufacturer’s instructions. A clean machine makes clean-tasting coffee. It’s that simple.

Step-by-step (brew workflow)

1. Select your beans: Choose high-quality, single-origin beans. For espresso, a mix of origins often works well. Think about flavor profiles you like.

• Good looks like: Beans with a recent roast date and a clean appearance.
• Common mistake: Using old or low-quality beans. Avoid this by buying from reputable roasters.

2. Weigh your coffee: Use a digital scale. Measure out your desired dose. For a double shot, 18-20 grams is a good starting point.

• Good looks like: Precise measurement. Your scale reads the exact weight you want.
• Common mistake: Guessing the amount. This leads to inconsistent shots. Use a scale, always.

3. Grind your coffee: Grind your beans just before brewing. Use a quality burr grinder. Aim for a fine, consistent grind.

• Good looks like: A uniform powder, not too clumpy or too dusty.
• Common mistake: Using a blade grinder or a worn-out burr grinder. This creates uneven particle sizes, leading to bitter or sour shots.

4. Dose the portafilter: Place the ground coffee into your portafilter basket. Distribute it evenly.

• Good looks like: A level bed of grounds with no major gaps or mounds.
• Common mistake: Tamping down unevenly. This causes channeling, where water finds paths of least resistance.

5. Tamp the coffee: Apply firm, even pressure. Aim for a level tamp. This compacts the grounds.

• Good looks like: A solid, flat puck of coffee.
• Common mistake: Tamping too hard or too lightly, or with an angle. This messes with water flow and extraction.

6. Lock in the portafilter: Secure the portafilter into the group head of your espresso machine.

• Good looks like: A firm, secure fit with no leaks.
• Common mistake: Not locking it in fully. This can lead to grounds spraying everywhere. Ouch.

7. Start the shot: Engage the brew cycle. Watch the espresso flow.

• Good looks like: A steady stream of rich, dark liquid that gradually lightens.
• Common mistake: Starting the shot too quickly without pre-infusion (if your machine has it). This can lead to uneven extraction.

8. Monitor the flow and time: Aim for your target yield within a specific timeframe. For a 1:2 ratio, 25-30 seconds is a common target.

• Good looks like: The espresso flowing like warm honey, hitting your target weight in the right time.
• Common mistake: Letting the shot run too long or too short. Too long = bitter. Too short = sour.

9. Stop the shot: Stop the brew cycle when you reach your target yield.

• Good looks like: You hit your weight goal precisely.
• Common mistake: Stopping too early or too late. This throws off your ratio and flavor.

10. Taste and adjust: Sip your espresso. Does it taste balanced? Bitter? Sour? Adjust your grind size for the next shot.

• Good looks like: A balanced shot with sweetness, acidity, and body.
• Common mistake: Not tasting and adjusting. You’ll keep making the same mistake.

Common mistakes (and what happens if you ignore them)

Decision rules (simple if/then)

• If your espresso tastes bitter, then grind finer because bitter indicates over-extraction.
• If your espresso tastes sour, then grind coarser because sour indicates under-extraction.
• If your espresso flows too fast, then grind finer because a faster flow means the grounds aren’t resisting water enough.
• If your espresso flows too slow or chokes, then grind coarser because a slow flow means the grounds are too compact.
• If your crema is thin and dissipates quickly, then check bean freshness and grind size because these are key to good crema.
• If your shot has visible spurts or uneven flow, then check your tamping and distribution for evenness because channeling is the likely culprit.
• If your espresso tastes weak, then increase your coffee dose or decrease your yield because you might be under-dosing or over-extracting.
• If your espresso tastes too intense, then decrease your coffee dose or increase your yield because you might be over-dosing or under-extracting.
• If your machine is making weird noises, then check the water level and descaling status because these can affect pump performance.
• If your espresso tastes “off” or metallic, then clean your brew path thoroughly because old oils can impart nasty flavors.
• If you’re using a new bag of beans, then expect to adjust your grind setting because different beans behave differently.

FAQ

How do I make an espresso blend?

Start with good single-origin beans. Roast them individually to your desired level, then mix them in proportions you like. Some people prefer to roast them together, but individual roasting offers more control.

What kind of beans are best for espresso?

Darker roasts, like Italian or French roasts, are traditional for espresso. However, many modern roasters use medium roasts, or even blends of light and dark, to achieve complex flavors. It really depends on your taste.

How fresh do my beans need to be for espresso?

Ideally, beans should be between 4 days and 3 weeks post-roast for optimal espresso. They still have plenty of CO2 to produce good crema. Older than a month, and the crema starts to fade.

What’s the deal with crema?

Crema is the reddish-brown foam on top of espresso. It’s made of emulsified oils and CO2. Good crema is a sign of fresh beans and proper extraction, but it doesn’t guarantee a delicious shot on its own.

How do I adjust my grind for espresso?

You adjust your grind based on the shot time and taste. If the shot runs too fast and tastes sour, grind finer. If it runs too slow and tastes bitter, grind coarser. It’s a continuous process of dialing in.

Is it better to buy pre-ground espresso or grind my own?

Always grind your own. Pre-ground coffee loses its aroma and flavor very quickly. Espresso requires a very specific, consistent grind that you can only achieve with a quality burr grinder right before brewing.

What is a “dialed-in” espresso shot?

A dialed-in shot is an espresso that tastes balanced and delicious. It means you’ve found the right combination of grind size, dose, yield, and time for your specific beans and machine.
