Whether it's the compact punch of a ristretto or the robust flair of an espresso, each offers a unique coffee experience. 

We'll explore the distinctions from beans to brew, helping you decide which might suit your taste buds better.

What is espresso?

An espresso is more than just a quick caffeine fix; it's a cultural icon. This coffee is brewed by forcing a small amount of nearly boiling water through finely-ground coffee beans. Known for its creamy consistency and intense flavour, espresso is often the base for many popular coffee drinks, such as lattes and cappuccinos. It’s typically served in small amounts, yet it packs a substantial taste that can be both complex and captivating.

What is ristretto?

Consider ristretto the espresso’s intense cousin. Using an espresso machine, this shot is made with the same amount of coffee but half the water, resulting in a shorter extraction time. The result is a more concentrated and often sweeter shot of coffee. Ristretto translates to “restricted” in Italian, which refers to limiting the water and maximising the flavour.

Key differences between ristretto and espresso

While ristretto and espresso share the same foundation, their differences lie in the details. From brewing techniques to flavour profiles, each delivers a distinct coffee experience. One of the most important distinctions is the brew ratio—espresso typically has a 1:2 ratio of coffee grounds to liquid (measured in weight), whereas ristretto is brewed at a more concentrated 1:1 ratio. This means that for the same amount of coffee, ristretto yields a smaller but more intense shot. Whether you prefer the bold richness of espresso or the smooth concentration of a ristretto shot, understanding these nuances will help you refine your coffee choices and elevate your home brewing skills. Here’s how they compare.

Brewing process

While both drinks start with a similar setup, the magic lies in the extraction. Espresso machines employ a swift extraction to yield a full espresso shot, whereas ristretto is all about a quick, sharp pull that limits extraction time and water, giving a shorter, more flavourful shot.

Flavour intensity and sweetness

If flavour were a canvas, espresso would be the broad strokes of intense, rich coffee, whereas ristretto would be the detailed dots of heightened sweetness and concentrated essence. The reduced extraction time for ristretto means less bitterness, making it a favourite for those who prefer a potent but smoother sip.

Caffeine content 

Contrary to popular belief, a ristretto shot has slightly less caffeine than an espresso due to its shorter water contact time. This means you can enjoy all the taste without quite as much of a buzz.

Serving size

Espresso is typically served in single or double shots, approximately 30ml or 60ml, respectively. Ristretto, being more concentrated, is usually about 15-20ml per shot, offering a bolder flavour in a smaller package.

How to brew ristretto and espresso at home

Brewing espresso and ristretto at home allows you to tailor every cup to your taste preferences. While both require similar equipment and techniques, small adjustments in grind size, water ratio, and extraction time make all the difference. Whether you're after the balanced depth of an espresso or the bold intensity of a ristretto, here’s how to perfect your brewing process at home.

Equipment needed

To get started, you’ll need a reliable espresso machine, high-quality coffee grinders, and other coffee accessories like a tamper to ensure the finest grind. High-quality espresso machines vary, so choosing the type of espresso machine that suits your coffee preferences is important.

Step-by-step guide for espresso

1. Fill your espresso machine with fresh, cold water.

2. Grind the coffee to a fine consistency similar to table salt.

3. Tamp the ground coffee evenly in the portafilter.

4. Lock the portafilter in place and start the machine.

5. Aim for a brew time of about 25 seconds to get that perfect espresso shot.

Adjustments for brewing ristretto

Follow the steps for espresso but adjust your grinder to a slightly finer setting. Use the same amount of coffee but half the water. Aim for a brew time of 25-30 seconds, as the finer grind slows extraction while maintaining the same duration.
