Key Takeaways

  • Robust porter is a complex beer style, offering a balance between roasted malt flavors and caramel sweetness.
  • This beer showcases a range of hop profiles and is available in both American and English styles.
  • Ideal for food pairings and varied glassware options, robust porters carry rich cocoa and coffee notes.


The history of the robust porter can be traced back to the 18th century as a stronger, roastier, and hoppier version of the traditional porter. The rise in popularity of pale ales during that time motivated brewers to create a darker, more robust alternative. The robust porter is differentiated from its counterpart, the brown porter, by having more bitter and roasted malt flavors, yet not quite as much as a stout.

Throughout its history, the robust porter has taken on various interpretations depending on the region and period. Traditional versions of the style feature a more subtle hop character, often with English hop varietals. In contrast, modern American interpretations of the robust porter tend to be considerably more aggressive in their hop bitterness and roastiness.

In 2013, a resurgence in the popularity of porters, including the robust variety, was witnessed around the world. As craft beer enthusiasts continue to explore the diverse range of beer styles, robust porters have attracted attention for their harmonious balance of caramel and malty sweetness, sharp bitterness, and roasted malt flavors, which often evoke notes of cocoa.

As a prime example of the beer’s adaptability and versatility, the Baltic porter, a former subtype of the robust porter, evolved to suit the tastes of the working class in the 18th century. Today, robust porters are brewed and enjoyed globally, showcasing the enduring allure and rich history of this dark, full-bodied beer.



Robust porter features a variety of specialty grains, which gives it its signature taste and character. One of the essential ingredients in a robust porter is malt. This ingredient determines the beer’s color, aroma, and flavor, and plays a significant role in the final taste of the beer.

The most commonly used malts in robust porters are black malt and chocolate malt. These malts impart a roasted flavor and can range from a subtle, cocoa-like taste to a more pronounced bitterness. While both black malt and chocolate malt contribute to the overall roastiness, the black malt also adds a slightly burnt character, distinct from the chocolate malt’s sweeter profile.

Apart from the two main malts, brewers often use smaller amounts of other malts to add complexity to the flavor profile, such as Munich malt and crystal malt. Munich malt provides a bready and malty sweetness that balances the roastiness of the robust porter, while crystal malt adds caramel-like flavors and helps to maintain the desired body and mouthfeel.

In some robust porter recipes, roasted barley is also included. This ingredient contributes to the bitterness and enhances the roasted flavors, but it’s important to note that it should not overpower the malt flavors. Roasted barley is used sparingly, and its presence should not be as dominant as it is in a stout.

To sum up, here’s an overview of the main malts used in a robust porter:

  • Black malt: Roasty flavor, moderately strong, lightly burnt character
  • Chocolate malt: Roasted cocoa-like taste, subtle to pronounced bitterness
  • Munich malt: Bready and malty sweetness
  • Crystal malt: Caramel-like flavors, body and mouthfeel
  • Roasted barley (optional): Bitterness, enhanced roasted flavors

When brewing a robust porter, the balance of these malts is essential, as it creates the unique harmony of flavors that sets this beer style apart.


When it comes to brewing a Robust Porter, the choice of hops plays a significant role in achieving the desired flavor profile. Hops contribute to the beer’s aroma and bitterness, balancing the sweetness of the malt, and enhancing the overall complexity of the beer.

In a Robust Porter, hop flavors and aromas typically range from very low to medium, with the focus primarily on the roasted malt character and balancing bitterness. While a variety of hop varieties can be used, some popular choices for this style include Kent Goldings and Fuggles.

Kent Goldings hops, originating from England, are known for their smooth and gentle bitterness, floral and earthy notes, and mild aromas. These characteristics make Kent Goldings a suitable choice for a Robust Porter, allowing the hops to complement the intense malt profile without overpowering it.

Fuggles hops are another English variety, often used in conjunction with Kent Goldings. Fuggles provide a slightly more robust and earthy bitterness, along with woody and herbal notes, which can add depth and complexity to the final beer. Utilizing both of these hop varieties can result in a well-rounded and harmonious flavor profile.

The hop additions in a Robust Porter typically occur during the boiling stage of the brewing process, with bittering hops added early in the boil to extract the required bitterness, and any aroma hops added later in the boil or even during fermentation as dry hopping. It is important to carefully calculate and measure your hop additions to achieve the desired balance between bitterness, flavor, and aroma while also taking into account your beer’s malt structure.

Key Properties

Robust Porter is a popular beer style that strikes a balance between a brown porter and a stout. It showcases more bitter and roasted malt flavors than a brown porter but falls short of a stout’s intensity. Fans of this beer often appreciate its harmonious blend of caramel and malty sweetness with the sharp bitterness of black malt.

The alcohol by volume (ABV) for a Robust Porter typically ranges from 4.5% to 6.0%. This moderate range appeals to those who enjoy a full-flavored beer without an excessively high alcohol content. Thanks to its bitterness, the International Bitterness Unit (IBU) for a Robust Porter usually falls between 25 and 50, providing a noticeable yet well-balanced hop bitterness.

In terms of Original Gravity (OG), Robust Porters exhibit a moderate range of 1.040 to 1.060, resulting in the potential for a pronounced malt character without excessive density. This ensures that the beer remains easily drinkable and doesn’t feel overly heavy on the palate.

The Standard Reference Method (SRM) is used to quantify the color intensity of a beer, and for Robust Porters, we can expect an SRM value between 22 and 35. This results in a deep brown to almost black color, often presenting ruby highlights when held to the light. This characteristic color matches well with the notable cocoa-like roast malt flavors that define the style.

Robust Porters’ combination of rich flavor profiles, balanced hop bitterness, and moderate alcohol content make them a popular choice for those looking for a more pronounced taste experience than a brown porter while maintaining greater drinkability than a stout.

Fermentation and Yeast

Robust Porter is an ale, which means that it is fermented using ale yeast. This type of yeast typically works at warmer temperatures, around 60-72°F (15-22°C), and produces fruity esters and other fermentation by-products that contribute to the beer’s complex flavor profile.

When fermenting a Robust Porter, it’s essential to choose the right yeast strain to achieve the desired balance of flavors. A versatile and popular choice for this style is the American ale yeast, known for its clean profile, soft nutty notes, and slightly tart finish. This strain is an excellent option for a “house” strain due to its consistent performance and adaptability to various American beer styles.

Fermentation temperature is an essential factor to consider when brewing a Robust Porter. To emphasize the malt and chocolate-like flavors of the style, it is recommended to ferment at the lower end of the yeast’s temperature range (around 60-66°F, 15-19°C). This temperature will suppress the production of fruity esters, ensuring that the focus remains on the malt character of the beer.

For a more pronounced hop bitterness and aroma in the finished product, some brewers may opt to dry-hop their Robust Porters. Dry-hopping involves adding hops to the fermenter, usually after the initial fermentation has slowed, to impart additional hop flavors and aromas to the beer. This technique is optional and entirely up to the brewer’s preference.

Appearance and Aroma

The Robust Porter is characterized by its medium brown to very dark brown color, which can sometimes approach black. The beer often exhibits ruby or garnet-like highlights that add depth to its appearance. It is important to note that its clarity may be challenging to discern due to its dark color; however, when not opaque, the beer is clear, particularly when held up to light.

A distinguishing feature of the Robust Porter is its full, tan-colored head. This head, when poured correctly, adds an enticing aspect to the beer’s presentation. The head retention of a Robust Porter is moderately good, meaning that the foam should persist for some time after pouring, enhancing its overall appearance.

In terms of aroma, the Robust Porter is known for its roasty notes, which often include a lightly burnt, black malt character. This aroma should be noticeable and can be moderately strong, providing an appealing olfactory experience. Additionally, some Robust Porters may exhibit optional malt characteristics, such as grainy, bready, toffee, caramel, chocolate, coffee, rich, and sweet scents.

The hop aroma in Robust Porters can range from low to high, with either US or UK hop varieties typically used. The right balance of aromas in a Robust Porter can captivate the senses and contribute to an enjoyable drinking experience.

Flavor Profile

The robust porter is a delightful beer that boasts a range of flavors, appealing to the taste buds of beer enthusiasts. While retaining its classic porter roots, the robust porter distinguishes itself by incorporating more bitter and roasted malt flavors. This elevates it above a brown porter, although not quite to the level of a stout.

The flavor profile of the robust porter is dominated by dark roasted grains, which exude rich and intricate tastes to the drinker. One main characteristic is its cocoa flavor, derived from the roasted malt. This imparts a subtle sweetness that harmonizes with the sharper bitterness of the black malt. The cocoa notes have an undeniable appeal, as they skillfully merge with the other flavors to create a remarkable drinking experience.

In addition to cocoa, coffee is another prevalent flavor in the robust porter. The presence of coffee nuances builds upon the complex array of tastes that already exist within the beer. The marriage of coffee and dark roasted grains imparts an earthy depth to the brew, which contributes to its overall allure.

Adding to the robust porter’s complexity are hints of chocolate, further accentuating the beer’s delightful spectrum of tastes. The chocolate notes intertwine with the previously mentioned flavors, creating a delightful symphony of tastes that please the palate.


The mouthfeel of a robust porter is an important aspect of the overall tasting experience. In general, this style of beer has a medium to medium-full body, providing a substantial and satisfying presence on the palate. The body contributes to the perception of richness and complexity that is characteristic of robust porters.

Carbonation plays a key role in the mouthfeel of a robust porter as well. These beers typically have moderately low to moderately high carbonation levels, enhancing the sensation of smoothness and drinkability. The carbonation also helps to lift and balance the bold, roasty flavors that are an integral part of this beer style.

A well-crafted robust porter should not have a particularly strong astringency, as this can detract from the overall enjoyment of the beer. However, a slight astringency originating from the roasted grains used in the brewing process can be acceptable, as long as it doesn’t dominate the experience.

American and English Styles

The Robust Porter style of beer showcases a complex, rich, and roasty flavor profile that has its roots in England. Over time, brewers in different countries have developed their unique interpretations of the porter style, leading to a distinction between English and American porters.

English Porters have a subtler flavor profile compared to their American counterparts, with a focus on balanced and harmonious notes of caramel and malt sweetness. The roast malt flavors in an English Porter typically resemble cocoa and may also include some coffee-like aspects. While English Porters still exhibit a sharp bitterness through the use of black malt, it is generally less intense than the American style.

Moving across the Atlantic, American Porters have given this classic beer style a new twist. American brewers often push the boundaries of the porter style by incorporating additional ingredients like coffee and chocolate, which further amplify the robust, roasted flavors. Another difference between the American and English Porters lies in the hop usage. In general, American Porters incorporate a higher level of hop bitterness, giving these beers a bolder character that appeals to American palates.

Pairings and Glassware

Robust porters are versatile when it comes to food pairings, offering rich and complex flavors that complement a wide variety of dishes. One of the ideal food pairings for a robust porter is roasted or grilled meats, as the beer’s roasted malt profile brings out the savory notes in the meat while also cutting through its richness.

Another delicious pairing for robust porters is gruyere cheese. The nutty and slightly sweet characteristics of gruyere cheese harmoniously blend with the chocolatey and caramel flavors present in a porter. This combination creates a satisfying and well-balanced dining experience.

Desserts also pair exceptionally well with robust porters, thanks to their notes of chocolate and coffee. One standout dessert option is peanut butter cookies, as the rich and creamy texture of peanut butter complements the robust flavors found in the beer. The combination of sweet and savory elements results in a memorable and indulgent treat.

When it comes to glassware, the nonic pint is the recommended choice for enjoying a robust porter. This type of glass, with its slight bulge near the top, allows for a good head retention while also enhancing the aroma and flavor profile of the beer. The ideal serving temperature for a robust porter should be between 50-55°F (10-13°C), as this range allows the beer’s complex flavors to shine while still maintaining its refreshing characteristics.

Commercial Examples and Awards

One popular commercial example of a Robust Porter is Black Butte Porter from Deschutes Brewery. This beer is very dark in color, has an opaque clarity, and features slow to fast rising carbonation bubbles. Its flavor and aroma profile exhibits mild alcohol and hop characteristics, and it overall has a very appealing taste for craft beer enthusiasts1.

Another notable example is Pig Iron Porter from Iron Hill Brewery & Restaurant. This beer, along with Moonlight Porter from Rock Bottom Restaurant & Brewery, showcases the range of flavors and appearance that can be found within the Robust Porter style1.
