We previously discussed the importance of ratios in coffee and how they are the foundation of any successful cup. Ratios are not just numbers on a scale; they are a tool in the barista's hands to control taste and texture, ensuring a consistent experience for the customer. Today, we continue our discussion and focus on two key areas that highlight the value of ratios: espresso and filter coffee.
It is important to know that there are different types of coffee beans, and each type may require different ratios to achieve the best flavor.

Why are ratios considered the "language of coffee"?
Ratios are the common language among baristas worldwide. When you say 1:2 or 1:16, you are defining the cup even before it's tasted. This language makes training clearer and reduces variations between cups at the same cafe, especially if you have multiple baristas working simultaneously.
The Importance of Water Ratio
When preparing specialty coffee, many people focus solely on the type of beans or the brewing method, but the water-to-coffee ratio plays a fundamental role in determining the quality of the final cup. Using an appropriate amount of water with coffee beans ensures a balanced extraction of flavors, resulting in a rich and flavorful cup of coffee. If the water quantity exceeds the required limit, you will notice that the coffee becomes weak and may lose some of its flavor depth. Conversely, if the water quantity is too low, you will get a very concentrated coffee that might be bitter or heavy on the palate. Therefore, adjusting the water-to-coffee ratio every time is the secret to preparing coffee perfectly, giving you the best flavor experience in every cup.
Espresso Ratios
Espresso is the drink that requires the most precision in ratios:
Ristretto: 1:1 to 1:1.5 – intense, thick, high sweetness.
Classic Espresso: 1:2 – perfect balance of bitterness, sweetness, and acidity.
Lungo: 1:3 or more – lighter in body, more noticeable acidity.
The number of ratios or types of espresso that can be prepared depends on the number of different ways to change the coffee-to-water ratio, and each ratio yields a different taste and experience.
Tip: Any barista working without a scale cannot maintain consistent quality. In/Out weight must become a daily habit.
Filter Coffee Ratios
Filter coffee offers more room for experimentation but relies on the same principle:
The Golden Ratio: 1:15 to 1:17 (grams of coffee: ml of water).
Example: 20 grams of coffee x 300 ml of water = 1:15.
- Also, there are other methods or ratios that can be tried in addition to the golden ratio, and each experiment may yield different results depending on personal taste.
The difference between 1:15 and 1:17 completely changes the cup: the first gives a strong and rich coffee, while the second is smooth and easier to drink. This is where training plays a role, as customers don't like to find a strong cup one day and a weak one the next.
The Impact of Ratios on Customer Satisfaction
Customers may not know what 1:2 or 1:16 means, but they feel the difference in the cup. Consistency is what builds trust between a cafe and its customers. If they find the same quality every time, your cafe will be their first choice. If they notice variations between cups, you might lose them even if the flavor is sometimes good.
The Importance of Training Your Team on Ratios
Consistent Quality: Customers expect the same taste every time.
Cafe Reputation: Consistent quality = customer loyalty.
Reduced Waste: Adjusting ratios means precise use of beans and water.
Barista Development: When baristas understand the numbers, they become flavor-aware and learn how to adjust it on demand.
How to Explain Ratios to a New Team?
Instead of giving baristas general instructions, teach them to measure with a scale. Explain to them that ratios are not just "information," but a tool that controls flavor. The best training method is to prepare the same coffee with three different ratios and let the team taste the differences themselves. Hands-on experience reinforces the information more than words.
How to Write a Preparation Ratio Guide for Your Cafe?
Professional cafes write an internal "playbook" that includes the approved ratios for each drink. For example: Cappuccino = 1:2 espresso + 150ml milk, V60 = 1:16… etc. Having this guide enables the team, especially new members, to work with unified standards and saves the cafe owner time and effort in daily training.
We've talked a lot about ratios – and today we reiterated their importance because we believe they are the foundation of cafe success. From concentrated espresso to calm filter coffee, understanding and precisely applying these numbers is what elevates the quality of your drinks and establishes your identity as a professional cafe. Don't underestimate the numbers, because they are simply the secret to a perfect cup that satisfies every customer.
