The latte. That creamy, comforting beverage that warms you on a cold day and provides a gentle caffeine kick to start your morning. But behind that simple facade of milk and coffee lies a question that has plagued home baristas and coffee aficionados alike: Do I use espresso or lungo for my latte?
The answer, like the perfect latte itself, is nuanced and depends on personal preference, the desired strength, and the specific flavor profile you’re aiming for. Let’s dive deep into the world of espresso, lungo, and lattes to unravel this coffee conundrum.
Understanding Espresso and Lungo: The Foundations of Your Latte
To make an informed decision about which coffee base to use for your latte, it’s crucial to understand the fundamental differences between espresso and lungo. They both originate from the same process – forcing hot water through finely-ground coffee beans – but variations in the brewing parameters result in vastly different characteristics.
Espresso: The Concentrated Classic
Espresso, derived from the Italian word for “expressed” or “forced out,” is the heart and soul of many coffee drinks. A classic espresso shot is typically around 30ml (approximately 1 ounce) in volume, brewed under high pressure (around 9 bars) for a short extraction time (around 25-30 seconds). This rapid extraction results in a concentrated, intense coffee with a rich crema – that desirable golden-brown foam on top.
The flavor profile of espresso is generally described as bold, robust, and complex. It features a concentrated sweetness, followed by notes of bitterness and acidity, all contributing to its distinctive character. The limited extraction time ensures that only the most desirable coffee compounds are extracted, resulting in a balanced and flavorful shot. Espresso offers a full-bodied flavor ideal as the base of a Latte.
Lungo: The Extended Extraction
Lungo, Italian for “long,” is essentially an extended espresso shot. It is brewed using the same amount of ground coffee as espresso but with roughly twice the amount of water (around 60ml or 2 ounces) and a longer extraction time (around 50-60 seconds). This prolonged extraction results in a larger volume of coffee with a significantly different flavor profile.
While lungo starts with the same initial flavors as espresso, the extended extraction pulls out additional compounds from the coffee grounds, including more bitter and astringent elements. This can lead to a less balanced and more intense, sometimes even burnt, taste. Some people find it bolder and more satisfying, while others perceive it as harsh and less refined. Lungo is an extraction that extends the espresso’s flavor profile into more bitter notes.
Lungo vs. Espresso in a Latte: A Comparative Analysis
Now that we’ve established the key differences between espresso and lungo, let’s explore how each one performs in a latte.
Flavor Impact on the Latte
The type of coffee base you choose has a direct impact on the overall flavor of your latte. Espresso contributes a strong, concentrated coffee flavor that cuts through the milk, creating a balanced and harmonious beverage. The sweetness of the espresso complements the sweetness of the milk, resulting in a pleasant and satisfying drink.
Lungo, on the other hand, will produce a latte with a bolder, more intense coffee flavor. The bitterness and astringency of the lungo can become more pronounced when combined with milk, potentially overshadowing the milk’s sweetness and creating a slightly unbalanced flavor profile. For those who prefer a very strong coffee taste, this might be desirable.
Strength and Caffeine Content
Espresso is known for its high caffeine concentration due to the rapid extraction process. Although the volume is smaller, the caffeine is more concentrated than in a lungo.
Lungo, with its larger volume and longer extraction time, tends to have a slightly higher overall caffeine content. The longer extraction allows more caffeine to be extracted from the coffee grounds. However, the caffeine concentration per unit volume is typically lower than in espresso. So, while you’re getting more caffeine overall in a lungo latte, the perceived strength might not be as intense due to the diluted flavor.
Milk-to-Coffee Ratio Adjustments
When making a latte with espresso, the standard milk-to-coffee ratio is typically around 2:1 or 3:1 (milk to espresso). This ratio allows the espresso to shine through while providing a creamy, smooth texture.
If you opt for a lungo in your latte, you might need to adjust the milk-to-coffee ratio to compensate for the larger volume and stronger flavor. You might find that using less milk (closer to a 1:1 or 2:1 ratio) helps to balance the flavor and prevent the latte from becoming too bitter or overpowering. Experimentation is key to finding the perfect ratio for your taste.
Factors Influencing Your Choice
Ultimately, the choice between espresso and lungo for your latte is a matter of personal preference. However, here are some additional factors to consider:
Your Preferred Coffee Roast
The type of coffee roast you use can significantly influence the flavor profile of both espresso and lungo. Light roasts tend to be more acidic and bright, while dark roasts are typically bolder, more bitter, and less acidic.
If you’re using a light roast, espresso might be the better choice for your latte, as it will highlight the coffee’s natural sweetness and acidity. A lungo with a light roast could potentially result in an overly acidic and unbalanced latte. Conversely, if you’re using a dark roast, a lungo might be a good option, as the extended extraction can help to mellow out the bitterness and create a more complex flavor profile. A darker roast will naturally lend itself to a pleasant and mild Lungo.
Your Brewing Equipment
The type of espresso machine you use can also play a role in your decision. Some machines are better suited for brewing espresso, while others are more versatile and can handle both espresso and lungo. If you’re using a manual espresso machine, you have more control over the extraction process and can fine-tune the parameters to achieve the desired flavor. Automatic machines, on the other hand, might offer pre-programmed settings for espresso and lungo, making the process more convenient.
Your Tolerance for Bitterness
As mentioned earlier, lungo tends to be more bitter than espresso due to the extended extraction time. If you have a low tolerance for bitterness, espresso is definitely the safer choice for your latte. If you enjoy a bold, slightly bitter coffee flavor, then you might appreciate the unique characteristics of a lungo latte.
The Art of Experimentation: Finding Your Perfect Latte
The best way to determine whether you prefer espresso or lungo in your latte is to experiment! Try making lattes with both types of coffee and compare the results. Pay attention to the flavor, strength, and overall balance of each drink. Adjust the milk-to-coffee ratio as needed to find the perfect combination that suits your taste.
Consider starting with a classic espresso latte and then try a lungo latte using the same coffee beans and milk. This will allow you to directly compare the differences in flavor and strength. You can also experiment with different coffee roasts and milk types to further refine your latte-making skills.
Beyond Espresso and Lungo: Other Coffee Options
While espresso and lungo are the most common choices for lattes, there are other coffee brewing methods that can be used to create unique and flavorful variations.
Ristretto: The Restricted Shot
Ristretto, Italian for “restricted,” is a short shot of espresso that is extracted for an even shorter time than espresso, typically around 15-20 seconds. This results in a smaller volume of coffee (around 15-20ml) with a sweeter, more concentrated flavor. Ristretto is often described as being less bitter and more nuanced than espresso.
A ristretto latte can be a delightful option for those who prefer a sweeter, less bitter coffee flavor. However, due to the smaller volume of ristretto, you might need to use a double shot to achieve the desired strength in your latte.
Americano: Espresso and Hot Water
An Americano is simply espresso diluted with hot water. It offers a similar flavor profile to espresso but with a less intense concentration. While not a traditional latte ingredient, it can be used as a base for a lighter, less rich latte. Using an Americano will provide a lighter, less dense coffee note to the beverage.
Cold Brew: A Smooth and Sweet Alternative
Cold brew coffee is made by steeping coarsely-ground coffee beans in cold water for an extended period, typically 12-24 hours. This slow extraction process results in a smooth, low-acid coffee concentrate with a naturally sweet flavor.
While not typically used in traditional lattes, cold brew can be a fantastic alternative for iced lattes. Its smooth, sweet flavor pairs well with milk and ice, creating a refreshing and flavorful beverage.
Mastering the Milk: The Perfect Complement to Your Coffee
No discussion about lattes is complete without addressing the importance of milk. The type of milk you use and how you prepare it can have a significant impact on the overall taste and texture of your latte.
Whole Milk: The Classic Choice
Whole milk is the traditional choice for lattes due to its rich, creamy texture and natural sweetness. It steams beautifully, creating a velvety microfoam that complements the coffee perfectly.
Low-Fat Milk: A Lighter Option
Low-fat milk can be used as a lighter alternative to whole milk. However, it tends to produce a less stable microfoam and may not have the same rich, creamy texture as whole milk.
Plant-Based Milks: Expanding Your Latte Horizons
Plant-based milks, such as almond milk, soy milk, oat milk, and coconut milk, are becoming increasingly popular as alternatives to dairy milk. Each type of plant-based milk has its own unique flavor and texture, so experimentation is key to finding the one that you prefer. Oat milk is generally considered to be the best plant-based milk for lattes due to its creamy texture and neutral flavor.
The Art of Steaming Milk
Regardless of the type of milk you use, proper steaming is essential for creating a perfect latte. Steaming milk involves introducing air into the milk to create microfoam, a velvety, smooth foam that is integrated into the milk. The ideal steamed milk should have a glossy sheen and a silky texture.

What is the primary difference between an espresso and a lungo?
The fundamental difference lies in the extraction time and water volume. An espresso typically involves a shorter extraction time (around 25-30 seconds) using approximately 1 ounce of water. This results in a concentrated shot with a balanced flavor profile, showcasing the beans’ inherent characteristics.
Conversely, a lungo is extracted for a longer period, often extending to 45-60 seconds, using about twice the amount of water (around 2 ounces). This extended extraction pulls out more compounds from the coffee grounds, including bitter and astringent ones, resulting in a more intense and potentially less balanced flavor than a traditional espresso.
How does the taste of a lungo differ from an espresso in a latte?
In a latte, an espresso contributes a rich, bold coffee flavor that complements the sweetness of the milk. The balanced acidity and crema of the espresso meld well with the milk, creating a smooth and harmonious beverage. The espresso’s characteristic flavors shine through, adding depth and complexity to the latte.
A lungo in a latte can result in a more assertive, potentially bitter taste. The increased extraction draws out more bitter compounds, which can overpower the milk and create a less balanced flavor profile. While some may appreciate the stronger coffee presence, others might find it less enjoyable due to the heightened bitterness.
Which type of shot, espresso or lungo, is better for a latte?
Generally, an espresso is considered the superior choice for a latte. The shorter extraction yields a balanced flavor profile that complements the milk’s sweetness without becoming overly bitter. The resulting latte has a smoother, more harmonious taste that appeals to a wider range of palates.
While a lungo can be used in a latte, it’s important to be aware of the potential for bitterness. Those who prefer a bolder, more intense coffee flavor might enjoy a lungo latte, but it’s often necessary to adjust the milk ratio or add a sweetener to balance the flavor and mitigate the bitterness.
Does the type of coffee bean matter when choosing between espresso and lungo for a latte?
Yes, the type of coffee bean significantly impacts the outcome of both espresso and lungo shots, and consequently, the flavor of a latte. Beans with inherent bitterness or darker roasts will be amplified in a lungo, potentially creating an excessively bitter latte. Lighter, fruitier roasts may be more suitable for a lungo, but careful attention to the extraction time is still necessary.
For an espresso, a balanced blend or single-origin bean is often preferred, as the shorter extraction showcases the coffee’s nuanced flavors. The choice of bean should complement the milk in the latte, avoiding overly acidic or bitter profiles. Experimentation with different beans is crucial to find the perfect pairing for your desired latte flavor.
Can the grind size affect the taste of espresso and lungo shots in a latte?
Absolutely, grind size plays a critical role in the extraction process and ultimately affects the taste of both espresso and lungo shots in a latte. For espresso, a fine grind is essential to create the necessary pressure and resistance for proper extraction. This allows the water to evenly saturate the coffee grounds and extract the desired flavors within the optimal timeframe.
If using a lungo, a slightly coarser grind might be considered to prevent over-extraction and excessive bitterness. However, finding the right balance is key, as a grind that is too coarse will result in an under-extracted shot with a weak and sour flavor. Experimenting with grind size is crucial to achieving the desired flavor profile for both espresso and lungo shots in a latte.
How does the milk type influence whether to use an espresso or a lungo in a latte?
The type of milk used in a latte can influence the choice between espresso and lungo. Full-fat milk, with its richer and sweeter profile, can often balance the potential bitterness of a lungo, making it a more acceptable option. The milk’s fat content helps to emulsify with the coffee oils, creating a smoother and more palatable beverage.
On the other hand, if using a leaner milk, like skim or almond milk, an espresso might be a better choice. These milk types have less fat and sweetness to counteract bitterness, so the balanced flavor of an espresso is more likely to create a harmonious latte. The coffee’s character will be more pronounced, so selecting a bean that complements the milk’s flavor profile is essential.
Are there any alternatives to espresso or lungo for a latte?
While espresso and lungo are the most common choices for a latte, alternatives exist. A ristretto, a shorter and more concentrated version of espresso, can provide a sweeter and less bitter option. Another possibility is using a moka pot to brew a strong coffee concentrate, although the flavor profile differs significantly from espresso and may require adjustments to milk ratios.
Cold brew concentrate can also be used in a latte, offering a less acidic and naturally sweeter flavor. The cold brew process extracts different compounds from the coffee grounds, resulting in a unique taste profile. However, it’s important to note that these alternatives will not replicate the specific characteristics of an espresso-based latte, and may require experimentation to achieve the desired balance of flavor and texture.
