Scotch Ale Vs Stout – What’s the Difference?

As a passionate brewer and beer enthusiast, I’ve had the pleasure of brewing and tasting countless beer styles over the years. Among the many styles that have caught my attention, Scotch Ale and Stout have always stood out due to their complexity and richness.

So, which one is best for you and what is the difference?

The answer depends on your personal preference, as both styles offer unique characteristics and flavor profiles. Scotch Ale is known for its malty sweetness and caramel flavors, while Stout is characterized by its roasted, coffee-like bitterness.

In this post, we’ll dive into the similarities and differences between these two classic styles, exploring their history, brewing process, appearance, aroma, and taste.

Let’s take a closer look at both styles to help you decide which one might suit your taste buds better:

1. History

Scotch Ale and Stout are two distinct styles of beer that have a long and fascinating history.

Scotch Ale, also known as Wee Heavy, has its roots in Scotland. The style originated in the 18th century and was a strong, malt-forward beer brewed for export to England. Its name comes from the fact that it was originally brewed in Scotland using malted barley that had been dried over peat fires, giving it a distinctive smoky flavor.

Over time, Scotch Ale became known for its rich, complex flavors and high alcohol content, making it a popular choice for special occasions and celebrations. In the early 20th century, the style fell out of favor as lighter, more refreshing beers became more popular, but it experienced a resurgence in the craft beer movement of the late 20th and early 21st centuries.

Stout, on the other hand, has its roots in England. The style was originally known as Porter, a dark, roasted beer that was popular among the working classes in London in the 18th century. Over time, brewers began to experiment with different variations of Porter, including the addition of roasted barley, which gave the beer a distinctively dark color and rich, roasted flavor.

The term “stout” was originally used to describe a stronger version of Porter, and over time it became a distinct style of beer in its own right. Guinness, the famous Irish brewery, played a major role in popularizing Stout in the 19th and early 20th centuries with the introduction of their iconic Guinness Draught Stout.

Today, Stout remains a popular style of beer, known for its dark color, rich flavor, and creamy mouthfeel. There are many different variations of Stout, including Dry Stout, Foreign Extra Stout, and Imperial Stout, each with its own unique flavor profile and brewing techniques.

Both Scotch Ale and Stout are beloved styles of beer with rich histories and complex flavors. Whether you prefer the smoky, malt-forward character of Scotch Ale or the rich, roasted flavors of Stout, there’s something for every beer lover to enjoy.

  • Initially known as “Stout Porter,” referring to its stronger and bolder characteristics
  • Gained popularity in Ireland, where it became synonymous with the iconic Guinness brand

2. Ingredients

Scotch Ale

  • Scottish malts, such as Golden Promise or Maris Otter, provide the foundation for the style’s rich, malty flavors
  • Caramel and roasted malts add depth and complexity
  • Traditional hops like Fuggles, East Kent Goldings, or Willamette add a subtle bitterness to balance the sweetness

  • Roasted barley and chocolate malts contribute to the distinct roasted flavors and dark color
  • Hops like Fuggles, East Kent Goldings, or Nugget provide a balancing bitterness

3. Brewing Process

Scotch ale and stout are two popular styles of beer that are known for their rich, complex flavors and dark color. Despite some similarities in appearance and taste, the brewing process for these two styles of beer differs significantly.

Scotch ale, also known as Wee Heavy, is a strong and malty beer that originated in Scotland. The brewing process for Scotch ale involves the use of a high proportion of malted barley, which is kilned at a higher temperature to produce a rich, caramelized flavor. The malt is then mashed with hot water to extract the sugars and other soluble compounds, and the resulting wort is boiled with hops to balance the sweetness and add bitterness. After fermentation, Scotch ale is aged for several weeks to allow the flavors to mellow and mature.

Stout, on the other hand, is a dark, roasty beer that was first brewed in Ireland. The brewing process for stout involves the use of roasted barley, which gives the beer its distinctive coffee-like flavor and aroma. The barley is roasted at a high temperature to create a dark color and complex flavor profile. The malted barley is then mashed and boiled with hops to create the wort, which is fermented with yeast. After fermentation, stout is often aged for a period of time to allow the flavors to develop and mature.

Scotch Ale

1. Mash at a higher temperature (around 154°F) to create a thicker, sweeter wort
2. Boil for an extended period (up to 2 hours) to develop caramel flavors
3. Use a clean, well-attenuating yeast strain to ferment the beer
4. Age for several months to allow flavors to meld and mellow


1. Mash at a lower temperature (around 150°F) to create a more fermentable wort
2. Include roasted barley and chocolate malts in the mash to achieve the desired color and flavor profile
3. Use a clean, well-attenuating yeast strain to ferment the beer
4. Consider adding adjuncts like coffee, chocolate, or lactose to enhance flavors and mouthfeel

In summary, the main difference between the brewing process of Scotch ale and stout is the use of different types of malted barley. Scotch ale uses a higher proportion of malted barley that is kilned at a higher temperature to create a rich, caramelized flavor, while stout uses roasted barley to create a dark color and coffee-like flavor.

Additionally, the aging process for Scotch ale and stout can vary, with Scotch ale typically aged longer to allow the flavors to mature and mellow.

4. Appearance

Scotch Ales typically have a deep amber to copper color, with a thick, creamy head that lingers for a while. They often have a clear appearance, with minimal haze. Some varieties of Scotch Ale may have a slight reddish hue, and they are typically darker than most pale ales.

Scotch Ale Vs Stout?

Stouts, on the other hand, are known for their dark color, which ranges from dark brown to almost black. They are opaque, with little to no clarity, and have a dense, creamy head. Stouts can have a variety of colors and textures, ranging from a thin, tan head to a thick, creamy, mocha-colored head.

Overall, the appearance of Scotch Ale and Stout differ significantly, with Scotch Ales being lighter and clearer in color, and Stouts being darker and more opaque.

Scotch Ale

  • Deep amber to dark brown color
  • Clear to slightly hazy
  • Moderate off-white to tan head


  • Dark brown to black color

5. Aroma

The aroma of Scotch Ale is typically malty and complex, with notes of caramel, toffee, and sometimes a hint of smoke. It may also have a fruity character, with aromas of dark fruit like plums or raisins. The use of specialty malts in the brewing process contributes to the unique aroma of Scotch Ale.

In contrast, the aroma of Stout is often characterized by roasted malt notes, including coffee and chocolate aromas. Depending on the style of Stout, there may also be hints of dark fruit or licorice. The use of roasted barley in the brewing process is what gives Stout its distinct aroma.

Both Scotch Ale and Stout can also have subtle hop aromas, but the focus is typically on the malty and roasted notes. The aroma of these beers can vary depending on the specific recipe and brewing techniques used by the brewer.

Scotch Ale

  • Rich maltiness with notes of caramel, toffee, and dark fruit
  • Subtle hints of roasted malt and smoke
  • Low to moderate hop aroma


  • Roasted malt character with coffee, chocolate, and sometimes burnt notes

6. Taste

Scotch Ale is a rich, malty beer that often has notes of caramel, toffee, and dark fruit. It is typically brewed with a variety of specialty malts, which give it a deep, complex flavor profile. The beer is also known for its high alcohol content, which can range from 6% to 10% or higher. Scotch Ale is typically served at a slightly warmer temperature than other beers, which allows the complex flavors to be more fully appreciated.

Stout, on the other hand, is a dark, roasted beer that is known for its coffee and chocolate flavors. It is brewed with roasted malts, which give it a distinctive flavor and a dark color. The beer is typically lower in alcohol than Scotch Ale, with most stouts falling in the 4% to 7% range. Stout is often served on nitro, which gives it a creamy, smooth mouthfeel.

While both Scotch Ale and Stout are dark beers with complex flavors, they have distinct differences. Scotch Ale is typically sweeter and maltier, while Stout is more roasty and bitter. Additionally, Scotch Ale is higher in alcohol and often served at a warmer temperature, while Stout is lower in alcohol and often served on nitro for a creamier mouthfeel.

Scotch Ale

7. Mouthfeel

Scotch ale is typically full-bodied and has a rich, malty character. It often has a slightly sweet flavor with notes of caramel, toffee, and dark fruit. The mouthfeel of a Scotch ale is smooth and creamy, with a medium to low level of carbonation. It can also have a slight warming sensation from its higher alcohol content.

Stout, on the other hand, is known for its thick and creamy mouthfeel. It has a roasted flavor with notes of coffee, chocolate, and sometimes even a hint of smoke. The carbonation level of stout is typically low, which enhances the creamy texture of the beer. The high level of proteins from the roasted malts used in stouts contributes to the thick and velvety texture that makes it feel almost like a meal.

In summary, while both Scotch ale and stout offer a rich and complex flavor profile, the main difference in their mouthfeel comes from their level of creaminess and carbonation. Scotch ale tends to have a smoother, medium-bodied mouthfeel, while stout offers a thicker and creamier texture that can almost feel like a dessert.
