What Are Espresso Extraction Ratios?
What is an espresso extraction ratio?
- It’s a recipe for making espresso
- It tells you how much coffee to use, how much espresso to make, and how long it should take
- Example: 18g coffee : 36g espresso : 25-30 seconds
Why Ratios are Important
- They help make tasty coffee consistently
- They can fix problems like sour or bitter coffee
- They help you make the same great coffee every time
How Ratios Change Coffee Taste ( guide for Coffee Cupping)
- Right ratio: Coffee tastes good, feels smooth, has nice foam on top
- Wrong ratio: Coffee might taste too strong, weak, sour, or bitter
Different Types of Ratios
- Ristretto (1:1): Very strong, intense flavor
- Normal (1:2): Balanced, most common
- Lungo (1:3): More liquid, lighter taste
Ratios can help make great coffee, but the best coffee is the one you enjoy drinking, find your perfect espresso, and experiment.
The Components of Espresso Extraction Ratio
The key parts of making espresso:
1. Dose (Coffee In)
- How much ground coffee you use
- Usually 7-10g for a single shot, 14-20g for a double
- More coffee makes stronger espresso
2. Yield (Espresso Out)
- How much liquid espresso you get
- Less liquid makes stronger espresso
- More liquid makes milder espresso
- Different amounts for different styles (ristretto, normal, lungo)
3. Time
- How long it takes to make the espresso
- Usually aim for 25-30 seconds
- Too fast (under 20s) can taste sour
- Too slow (over 35s) can taste bitter
All these things work together, if you change one thing you might need to change others. Experiment and find your perfect espresso.
Common Espresso Ratio Standards
Different espresso ratios:
- Traditional Italian (1:2): For every 1 part coffee, you get 2 parts espresso, classic and balanced taste
- Modern Specialty (1:2.5): A bit more beverage espresso than the traditional ratio, can bring out more flavors
- Ristretto (1:1): Equal parts coffee and beverage espresso, very strong and intense flavor
- Lungo (1:3): More beverage espresso compared to coffee, lighter taste, more to drink
The “Golden Ratio” Debate
- Some people think there’s one perfect ratio
- Others say the best ratio is what you enjoy most
As you experiment, you will find different ratios create different tastes, don’t worry about being “correct”.
How to Measure and Control Espresso Ratios
Here’s a simple guide to measuring coffee for espresso:
Important Tools:
- Precise Scale: Measures coffee to 0.1 grams, helps get the same amount of coffee each time
- Timer: Measures to 0.1 seconds, helps control how long water runs through coffee
Making the Same Amount Each Time:
- Use a special cup to measure coffee
- Tap the holder to settle the coffee
- Use tools to spread coffee evenly
Measuring How Much Espresso You Get:
- Put your cup on the scale
- Start the machine and watch the weight
- Stop when you get the right amount
Timing Your Espresso:
- Aim for 25-30 seconds usually
- Start timer when you start the machine
- Some people start when coffee first drips
Usually, tools help make better coffee, you can adjust based on taste, and don’t forget to enjoy your coffee too!
Factors Affecting Espresso Extraction Ratios
Things that affect how espresso is made:
1. Coffee Grind Size:
- Too fine: coffee comes out very slowly
- Too coarse: Coffee comes out too fast
- Just right: Coffee flows nicely
2. How Fresh the Coffee Is (How To Choose Coffee Beans)
- Very fresh: Might make bubbly coffee
- Too old: Weak flavor, no crema
- Best: Use coffee 5-14 days after roasting
3. Machine Settings
- Pressure: Usually aim for 9 bars
- Temperature: Try for 195-205°F (90-96°C)
- Right settings make tasty coffee
4. Water Quality
- Hard water: Can clog the machine
- Soft water: Can make flat-tasting coffee
- Best: Water with some, but not too many, minerals
Making great espresso takes practice; things work together, and some changes can make big differences in your coffee.
Dialing In Your Espresso: A Step-by-Step Guide
This is a simple guide to making your espresso taste better:
1. Start with a Basic Recipe
- Try using twice as much espresso as coffee
- Example: 18g coffee makes 36g espresso in 25-30 seconds
2. Adjust How Fine You Grind the Coffee
- If coffee comes out too fast, grind finer
- If coffee comes out too slow, grind coarser
- Aim for 25-30 seconds
3. Taste Your Coffee

- Too bitter? It might be over-extracted
- Just right? You’ve found the sweet spot!
4. Change How Much Espresso You Make
- For stronger taste, make less espresso
- For milder taste, make more espresso
5. Slightly Change How Much Coffee You Use
- Small changes can make a big difference
- Try 0.5g more or less at a time
6. Repeat for Different Coffees
- Each type of coffee might need different settings
Making great espresso is like a puzzle, keep trying and you’ll get better!
Tasting and Evaluating Espresso Based on Ratios

The Science Behind espresso extraction ratios
The science behind espresso:
1. Total Dissolved Solids (TDS)
- How much coffee stuff is in your drink
- Good espresso is usually 8-12% coffee stuff
2. Extraction Yield
- How much flavor you got out of the coffee
- Best flavor is when you get 18-22% of the good stuff
3. How Coffee Flavors Come Out
- First: Sour and bright flavors
- Then: Sweet flavors
- Last: Bitter flavors
5. Different Parts of Coffee Dissolve Differently
- Some parts dissolve fast (like caffeine)
- Some parts are slower (like sugars)
- Some parts are very slow (like bitter stuff)
Good coffee balances all these things, it’s okay to experiment to find what you like. You don’t need to understand all the science to enjoy coffee, the best coffee is one that tastes good to you
espresso extraction ratios Considerations for Different Roast Levels
Here’s a simple guide to making espresso with different roasts: Guide for Coffee Roast
Light Roast Coffee
- Use more water (like 1:2.5 or 1:3 coffee to water)
- Grind coffee very fine
- Takes longer to make
- Tastes bright and light
Medium Roast Coffee

FAQs
1. What’s the ideal espresso ratio?
The classic ratio is 1:2, for every gram of coffee, extract 2 grams of espresso. Start with 18g of ground coffee to yield 36g of espresso in about 25-30 seconds.
This balanced ratio typically provides optimal flavor extraction. Adjust to taste: use 1:1.5 for ristretto (stronger) or 1:2.5 for lungo (lighter). Experiment to find your perfect balance.
2. How do I adjust my grind to improve extraction?
If your shot pulls too fast (under-extracted, sour), grind finer. If it’s too slow (over-extracted, bitter), grind coarser.
Make small adjustments, even tiny changes can have big effects. Aim for a 25-30 second extraction time. Keep your dose consistent and only change one variable at a time for accurate results.
3. What’s the importance of tamping in espresso extraction?
Tamping creates an even bed of coffee for water to pass through, ensuring uniform extraction. Apply about 30 pounds of pressure and keep the tamp level.
Consistency is key, maintain the same pressure each time. Poor tamping can lead to channeling, where water finds the path of least resistance, resulting in uneven extraction.
4. How does water temperature affect espresso extraction?
Ideal temperature is between 195°F and 205°F (90°C-96°C). Too cool leads to under-extraction (sour, weak), while too hot causes over-extraction (bitter, harsh).
Many machines maintain this automatically. If yours doesn’t, try pulling a blank shot first to heat the group head. For lighter roasts, aim for higher temperatures; for darker roasts, go slightly cooler.
5. What’s the role of pre-infusion in espresso extraction?
Pre-infusion wets the coffee grounds at low pressure before full extraction, ensuring even saturation. This helps prevent channeling and can lead to more balanced flavors.
If your machine has this feature, start with 3-5 seconds of pre-infusion. Adjust based on taste, longer for lighter roasts, shorter for darker ones. It’s especially helpful for fresh, gassy coffee.
