Whether an avid coffee fan or a professional barista, a perfect shot can sometimes go wrong, over-extracting and yielding too much espresso. This could be frustrating, especially when trying to make your customers happy.
Fear not, as there are ways to reduce the yield of espresso shots and return to making the perfect cup of coffee. This blog post will share tips and tricks to save your coffee from being wasted and help you create the perfect espresso shot.
5 Effective Methods to Reduce Espresso Yield
1. Use a Finer Grind Size
When trying to reduce the yield of your espresso shot, a finer grind size will help you achieve that.
The finer the coffee ground, the slower the water will pass through the coffee, which ultimately leads to a decrease in yield, resulting in a more concentrated and stronger shot of espresso.
2. Adjust Your Tamping Pressure
The amount of coffee you use for an espresso shot and the pressure with which you tamp it is also important. Pressing the tamped coffee down harder will decrease the amount of water that drips through the coffee and thus reduce the yield.
3. Shorten Brew Time
Espresso should be brewed in a range of 20-30 seconds, so if your extraction time exceeds this range, it will lead to an over-extracted shot with a higher yield.
To reduce the yield, you must focus on cutting back the brew time by using a finer grind or adjusting the water pressure. This will produce a shot with a more desirable taste and appearance.
4. Adjust Your Water Pressure
When pulling a shot, the amount of pressure applied to the coffee can impact the yield. Increasing the water pressure during your extraction process will decrease the brew time and the volume of the espresso produced in the cup.

5. Monitor Your Shot Yield
It’s really important to monitor your shot yield as you prepare espresso; that way, you can keep track of the amount of coffee you use and maintain consistency.
For example, if you know that your shot yield is usually 50 grams, you can adjust your grind size or the tamping pressure before and during the brewing process.
What is the Correct Espresso Extraction Ratio?
To understand the importance of the espresso extraction ratio, it’s helpful first to understand how espresso is made. Hot water is forced through finely-ground coffee beans at high pressure, resulting in a concentrated, flavorful shot of coffee. But getting the extraction ratio right is key to ensuring the shot tastes as it should.
So, what is the correct espresso extraction ratio?
While there is no universal answer, a common guideline is to use a 1:2 ratio of coffee to water. That means you should aim to extract two grams of espresso for every gram of coffee used. However, some baristas prefer a 1:1 ratio, while others allow a 1:3 ratio.
While the ratio itself may vary, what’s important is consistency. Most baristas will use a scale to measure coffee and water to achieve that. This ensures that each shot is brewed with the same amount of coffee and the same amount of water, resulting in a consistent flavor profile.
Another thing to remember regarding extraction ratios is the ‘yield.’ This refers to the amount of espresso extracted from the coffee grounds. An ideal yield for a double shot of espresso is around 60ml (or two ounces), with an extraction time of around 25-30 seconds.
But what happens if you don’t get the extraction ratio right?
An under-extracted espresso shot will taste sour and weak, while an over-extracted shot will taste bitter and burnt. Achieving the perfect balance of sweetness, acidity, and bitterness is the key to a delicious espresso shot.
How to reduce espresso yield in a coffee machine
If the espresso yield is too high, your coffee will taste weak and watery. You need to adjust the grind size, tamping pressure, and dose to reduce the yield.
- Start by adjusting the grind size. If the grounds are too coarse, the espresso will taste weak.
- On the other hand, if the grind size is too fine, the yield will be too high.
- Increase the tamping pressure slightly to reduce the yield.
- You may need to adjust the dose if you’re still not getting the desired yield.
- The more coffee you pack into the portafilter, the lower the yield.
How to calculate espresso extraction yield
To calculate the extraction yield, weigh the amount of coffee used, the espresso volume produced, and the brewing time.
Divide the espresso’s weight by the coffee’s weight, and you’ll get the extraction yield as a percentage. Most espresso blends have an ideal extraction yield of 18% to 22%. You must adjust the parameters to get the desired yield if the yield is too high or too low.
How to make sure your espresso dose yield time is just right
The ideal dosage for a standard single shot is around 7 grams, while a double shot requires around 14 grams. The dose should be evenly distributed and tamped down firmly to ensure consistent extraction.
The yield time should be between 20 to 30 seconds for optimal extraction. If the time is too short, the coffee will taste weak and sour, while a prolonged extraction can result in bitter and over-extracted coffee.
Importance of water quality and temperature
Besides the yield, dose, and extraction time, water quality and temperature also play a critical role in espresso extraction. The water temperature should be between 195 to 205 degrees Fahrenheit for best results.
Use filtered or bottled water to avoid impurities affecting the coffee’s taste. Always describe your espresso machine regularly to prevent mineral buildup and ensure the machine’s longevity.
There are many ways to reduce espresso yield, as we’ve explored in this post. From adjusting grind size, tamping pressure, and water pressure to monitoring shot yields, there are numerous ways to ensure your espresso shot is just right.
Remember, it’s all about taste, so don’t be afraid to experiment and find what works for you and your customers.
By following these tips and tricks, you can ensure your espresso shots are perfectly extracted every time. So, take your time and prepare to create the perfect cup of coffee for yourself or your customers.
