In this article, we'll explore the differences between single and double coffee in detail, focusing on aspects such as quantity, flavor, caffeine, and preparation methods. We'll also cover the benefits of each type and tips for choosing the right one for you.

This article is designed to be a comprehensive guide to help you understand the difference between single and double coffee. We'll also discuss how to incorporate this knowledge into your daily routine, whether you're using a home machine or visiting a coffee shop.
What is Single Shot Espresso?
Single coffee, or single shot espresso, is the basic and traditional form of espresso. This method originated in Italy in the early 20th century, where the first espresso machines were invented to prepare quick, strong coffee. A single shot is prepared using a small amount of ground coffee beans, typically 7 to 9 grams, extracted under high pressure (around 9 bars) using hot water (90–96°C) for 25–30 seconds.
The result? A small cup containing about 30 ml of espresso with a rich crema (the thick golden layer on top of the liquid). This type of coffee brings out the coffee's essential flavors purely, such as light acidity or fruity notes, without being overpowering. If you're using a home machine like the De'Longhi Dedica, the "single" button is specifically designed to extract this amount automatically.
Historically, the single shot was the standard in Italian cafes, served as a quick post-meal drink. Today, it's preferred by those seeking a balanced coffee experience without excess caffeine, especially in the early morning or late afternoon.
What is Double Shot Espresso?
A double shot, or espresso double shot, is simply double the amount of coffee a single serves. It's prepared using 14 to 18 grams of ground coffee, extracting approximately 60 ml of liquid. This type became popular in the United States and Europe during the 1980s, with the rise of specialty coffee culture and the emergence of chains like Starbucks, which often uses doubles as the basis for their drinks.
In preparation, the double shot takes a similar amount of time (25–30 seconds), but produces a stronger, more concentrated espresso. The crema is thicker, and the flavors are deeper, such as dark chocolate or spices. In modern machines, the "double" button is used for automatic extraction, making it ideal for beginners.
The double shot is the preferred choice for strong coffee lovers and is often used as a base for other drinks such as lattes or cappuccinos, adding extra strength without altering the balance.
The main difference between single and double coffee
Now, let's examine the differences between single and double coffee directly. These differences aren't just in size; they also affect the overall experience:
Quantity and size :
- Single: 7-9g coffee, 30ml liquid.
- Doubles: 14-18 grams of coffee, 60 ml of liquid. This difference makes the double larger, making it suitable for long sessions.
Flavor and concentration :
- The single brings out the subtle flavors and acidity, making it smoother.
- Double is stronger, with more bitterness and rich flavors like cocoa or nuts. If you prefer a light coffee, choose a single; if you're looking for excitement, double is the choice.
Caffeine content :
- Single: About 63 mg of caffeine.
- Double: About 126 mg of caffeine. This makes double ideal for long days, but it may be too strong for some.
Preparation time and grinding degree :
- Both types take a similar amount of time, but double requires a finer grind to maintain balance. In machines like the De'Longhi, the difference lies in the size of the basket.
Cost and consumption :
- Single is less expensive to consume daily, while double consumes twice the amount of coffee.
These differences make each type appropriate for a different context. For example, in cafes, the double is often the default in America, while in Italy, the single is the norm.
How to prepare single and double coffee at home
To prepare the perfect espresso, start by selecting high-quality beans, such as Arabica from Ethiopia for acidity or Robusta for strength. Use a grinder to obtain a fine grind, then press the beans into a 15 kg portafilter.
- For singles : Use a small basket, 7-9 grams, extract 30 ml in 25-30 seconds.
- For doubles : Large basket, 14-18g, 60ml extract.
Tip: Watch the flow – it should be like warm honey. If it's too fast, finer the grind; if it's slow, coarser.
Benefits of single versus double coffee
- Single benefits : Less caffeine to avoid fatigue, pure flavor, ideal for beginners or those with caffeine sensitivity. Aids concentration without overindulgence.
- Benefits of double squash : More energy, rich flavors, suitable for athletes or those working long hours. Contains more antioxidants due to the large quantity.
In studies, coffee has been shown to reduce the risk of heart disease, but moderation is important.
When to choose single or double coffee?
