Espresso Brew Guide
Espresso is coffee at its smallest and strongest. A concentrated base for most café drinks, it’s made using an espresso machine, where near boiling water is forced through a compacted bed of finely ground coffee at high pressure. This process extracts intense flavour in a short amount of time, producing a liquid with a viscous body that carries the signature crema on top.

Our Approach
Recipe: Coffee: 18g (fine) | Yield: 36g | Extraction time: 32 seconds
Equipment: Fellow Series One | Acaia Scales | Resolute
Step by Step Guide
Step 1
Turn on the espresso machine and allow it to preheat. Fill the water reservoir with fresh water.
Step 2
Remove the portafilter and wipe it completely dry, ensuring no old grounds are present and flush the group head by running a short stream of hot water through it.
Step 3
Grind 18g of coffee to a fine consistency (icing sugar texture) and place into the portafilter basket. Evening out the coffee in the basket by tapping the portafilter on the side using your finger or using a distribution tool.
Step 4
With the edge of the portafilter handle on the counter (or tamping mat), use your body weight to gently tamp the ground coffee in the basket and wipe off any loose grind coffee on the rim. Insert and lock the portafilter into the group head.
Step 5
Place your scales and cup under the spouts. Tare the scales. Begin the extraction by pressing the double shot button and start the timer.
Step 6
Stop the shot when the scale reaches ~34 g to account for final drips, aiming for 36g total. For this recipe, the ratio is 36g yield of espresso in 28–32 seconds. Give the espresso a gentle swirl and serve immediately.
Why Brew Espresso at Home?
Brewing espresso at home gives you a high-quality base for creating a wide range of coffee drinks. A well-made espresso is delicious on its own, but it also forms the foundation of flat whites, cappuccinos, lattes, and iced coffees. Making it yourself gives you complete control over how your coffee tastes; you can dial in each shot to your preference simply by adjusting the grind, dose, and yield. There’s a learning curve, but one that rewards you quickly; even small, intentional changes to your technique or recipe can lead to noticeable improvement, making the process both educational and satisfying.
Expert Tip
"Espresso rewards precision, but it doesn't need to feel intimidating. Focus on consistency rather than perfection; weigh your coffee, keep your technique repeatable, and make one adjustment at a time. Before long, you'll understand exactly how each change affects the cup."
Freda Yuan, Director of Coffee
Brewing Tips
- To keep your machine in good condition and your coffee tasting its best, it’s essential that you fully clean your machine after every use. Flush the group head between shots to reduce grind buildup and perform backflush cleaning according to the manufacturer's instructions.
- When experimenting with brew ratios and recipes, isolate the variables and change one thing at a time; this way, you can understand the effects of each.
- If your shot runs too fast, try a finer grind to slow the flow and increase extraction.
- If your shot runs too slow, try a coarser grind to quicken the flow and reduce extraction.
- Freshness plays an important role in espresso extraction. We recommend using coffee within a few weeks of roasting, and grinding immediately before brewing wherever possible.
- For espresso served black, coffees with vibrant acidity and bolder, fruit-forward characteristics are great options to explore. Washed coffees often express greater clarity, floral or citrus-forward notes which shine when served as espresso.
- If you are preparing milk-based drinks such as flat whites, cappuccinos or lattes, you might want to opt for coffees with chocolate, caramel or nut notes that pair smoothly with milk
Frequently Asked Questions
Espresso requires a fine grind, similar in texture to icing sugar. If your shot runs too quickly, grind finer. If it runs too slowly, grind slightly coarser.
As a starting point, aim for a 1:2 brew ratio (18g of coffee producing 36g of espresso) in approximately 28-32 seconds. Small adjustments can then be made to suit your coffee and taste preferences.
A sour espresso is often under extracted, meaning the water hasn’t dissolved enough flavour from the coffee. Try grinding finer, increasing your extraction time slightly, or checking that you’re using enough coffee.
Bitterness is usually caused by over extraction. Grinding slightly coarser or shortening the shot can help produce a sweeter, more balanced espresso.
You can, but freshly ground coffee produces significantly better results. Espresso is particularly sensitive to grind size, so immediately before brewing offers much greater control and freshness.
Crema is mostly influenced by coffee freshness, roast profile and brewing technique. Freshly roasted coffee, the correct grind size and proper extraction pressure will usually produce a thicker, more stable crema.
