Why Is Lungo More Bitter Than Espresso?
Lungo tends to be more bitter than espresso due to the extended extraction process. In making a lungo, more water is passed through the coffee grounds for a longer time than with an espresso.
This prolonged extraction not only captures the desired flavors from the coffee but can also extract undesirable compounds, such as bitter-tasting quinic acids.
Espresso, with its shorter extraction time, tends to emphasize the sweet and aromatic compounds in the coffee while minimizing the extraction of these bitter compounds. It’s the balance of extraction time and water volume that differentiates the taste profiles of these two brew methods.
Key Takeaways
- Lungo is more bitter than espresso due to its longer extraction time and increased extraction of bitter compounds.
- Factors such as coffee bean selection, grind size, and brewing temperature also contribute to the bitterness of lungo.
- The extended extraction time of a lungo allows for more water-to-coffee contact, leading to dilution of flavors and a more pronounced bitterness.
The Difference Between Lungo and Espresso
Lungo and espresso differ in their preparation, taste, and caffeine concentration.
Preparation
You pull a lungo shot slower than an espresso. It has more water too. This makes it taste stronger and more intense. Both drinks use the same amount of coffee grounds, but a lungo uses double the water.
The longer time needed to make a lungo brings out more bitter tastes from the coffee beans. Also, less crema forms on top of a lungo compared to an espresso because of how long it takes to brew.
Taste
A lungo has a more bitter taste compared to espresso. The longer extraction time of a lungo shot results in the increased extraction of bitter compounds from the coffee grounds, making it more intense and bitter.
Although a lungo is slightly less intense than espresso, its bitterness can make it seem stronger. The water-to-coffee ratio in a lungo is higher, which leads to dilution of flavors and a more pronounced bitterness.
So, if you prefer milder coffee with less bitterness, espresso might be a better choice for you.
Caffeine Concentration
The caffeine concentration in a cup of lungo or espresso depends on how long the water and coffee are in contact during extraction. The longer extraction time of a lungo shot means that more caffeine is extracted from the coffee grounds, resulting in a higher concentration of caffeine compared to espresso.
The overall caffeine content can vary depending on factors like bean selection and brewing temperature. So while lungo shots may be more bitter than espresso, they also tend to have a slightly higher caffeine kick.
Why Lungo is More Bitter Than Espresso
Lungo is more bitter than espresso due to its extended extraction time, which leads to an increased extraction of bitter compounds and dilution of flavors.
Extended extraction time
A lungo shot takes longer to extract than espresso, which contributes to its increased bitterness. During the extraction process, hot water passes through the ground coffee for a longer period of time, allowing more bitter compounds to be extracted from the beans.
As a result, the flavor becomes more intense and slightly more bitter compared to a standard espresso shot. The extended extraction time allows for a greater release of these bitter compounds into the final drink.
Increased extraction of bitter compounds
The increased extraction of bitter compounds is one reason why lungo is more bitter than espresso. When making a lungo, the water has more time to come into contact with the coffee grounds, which leads to a longer and slower extraction process.
This extended extraction time allows for more bitterness from the coffee beans to be extracted into the drink. As a result, the longer brewing time of a lungo shot contributes to its intensified bitterness compared to espresso.
Dilution of flavors
The dilution of flavors refers to the fact that a lungo shot has more water compared to espresso, which can affect its taste. When making a lungo, more water is passed through the coffee grounds for a longer period of time, resulting in increased extraction and dilution of compounds from the coffee beans.
This can lead to a milder and less concentrated flavor profile compared to espresso. However, despite being milder overall, the extended extraction time also allows for more bitter compounds to be extracted from the beans, resulting in a stronger bitterness in the final drink.
So while a lungo may have double the amount of water as an espresso shot, this dilution does not necessarily make it less bitter than espresso.
Factors That Influence Bitterness in Lungo
Coffee bean selection, grind size, and brewing temperature all play a role in the bitterness of lungo. Want to know more about how these factors affect the taste? Keep reading!
Coffee bean selection
The type of coffee beans used in brewing a lungo or espresso can also play a role in the bitterness of the drink. Different coffee bean varieties have different flavor profiles, including their level of bitterness.
Some types of coffee beans may naturally have more bitter compounds, resulting in a more pronounced bitterness when brewed as a lungo.
The selection of coffee beans is an important factor to consider when aiming for a specific taste profile, whether it’s a milder and less bitter espresso or a more intense and bitter lungo.
Grind size
The grind size of coffee beans plays a crucial role in the taste and bitterness of lungo and espresso. A finer grind size is typically used for espresso, which means that the coffee particles are smaller.
This finer grind allows for a faster extraction process, resulting in a shorter contact time between the water and coffee grounds. On the other hand, lungo requires a coarser grind size because it has more water passing through it during extraction.
The larger coffee particles take longer to extract, leading to an extended contact time with the water. This prolonged interaction can result in an increased extraction of bitter compounds from the coffee grounds, making lungo shots more bitter than espresso shots.
Coffee beans ground at different sizes have an impact on how flavors are extracted during brewing. In general, larger grinds tend to produce milder flavors while finer grinds yield more intense ones.
When it comes to lungo and espresso, the different grind sizes contribute significantly to their distinct tastes and levels of bitterness.
Choosing the right grind size is essential when brewing either lungo or espresso as it directly affects their flavor profiles. Using a coarser grind for lungo results in an extended extraction time but also leads to greater bitterness due to increased exposure to water.
Conversely, using a finer grind for espresso ensures a quicker extraction process with less contact time between water and coffee grounds, resulting in a stronger flavor profile that is less bitter compared to lungo.
Brewing temperature
The brewing temperature also plays a role in the bitterness of lungo. When the water is too hot, it can extract more bitter compounds from the coffee grounds, leading to a stronger and more bitter taste.
If the water is not hot enough, it may not fully extract all the flavors from the coffee, resulting in a milder taste. Finding the right brewing temperature is important in achieving a balanced and enjoyable lungo shot.
Conclusion
Lungo is more bitter than espresso because of its longer extraction time and increased extraction of bitter compounds. This bitterness can make it seem stronger even though it has more water than espresso.
Factors such as coffee bean selection, grind size, and brewing temperature also play a role in the overall bitterness of a lungo shot. So if you prefer a milder taste, stick to a standard espresso shot instead!
FAQ
What makes lungo more bitter than espresso?
The intensity of the coffee brewing methods used by the espresso machine plays a part in making lungo more complex thus, more bitter compared to espresso.
Is there any way I can make my lungo less bitter?
Yes! By controlling your brewing time with your espresso machine and adjusting for desired intensity, you can reduce the bitterness of your lungo.
Does adding milk like in a latte change the taste of our coffee?
Certainly, crafting a latte from an intense brew will create a different version oftaste as it combines with milk which tends to soften its flavor.
What is responsible for the complex taste profile found in Lungos compared to Espressos?
It’s mostly due to how each type is brewed: Espresso shots are short using less water which creates an intense but sweet cup; while Lungos use more water that drips through coffee grounds longer extracting other flavors making it slightly bitter.
