The brewing process of a classic Scottish Ale involves one or two mashing steps at higher temperatures, often above 160ºF, followed by a kettle caramelization process. This method, combined with the cold fermentation temperatures due to Scotland’s harsh climate, results in a full-bodied beer with very low attenuation yeast levels. To prepare a true Scottish Ale, it is crucial to use pale malt and pay close attention to the fermentation process to create an ale that evokes the proud heritage of Scottish brewing.
For those passionate about brewing, exploring various Scottish Ale recipes can lead to discovering diverse selections of beer, ranging from the light 60/- shilling ale to the robust “wee heavy” strong ales. Each recipe offers a unique opportunity to experiment with different malt types, hops, and yeast, creating a distinct and enjoyable experience with each batch brewed.
History of Scottish Ale
Scottish Ale has a rich and varied history that traces its origins back to the brewing traditions of ancient Scotland. The early brewers of this nation were known to incorporate a plethora of spices, herbs, and ingredients native to their land, which played a significant role in shaping the distinct flavor profiles of the ales they produced.
In the earlier days of its production, Scottish Ale was brewed using traditional methods that were unique to the region. Due to the harsh climate of Scotland, the brewers would often mash at higher temperatures, resulting in a kettle caramelization process that gave the beer its full-bodied flavor. Additionally, the ales were fermented at relatively cold temperatures, yielding a low attenuation yeast level.
As time passed, the brewing industry in Scotland evolved and expanded, with the number of breweries reaching a peak of 280 in 1840. However, this number started to decline due to mergers and closures, leaving brewing primarily concentrated in large firms located in Edinburgh, Glasgow, and Alloa by the 20th century.
One interesting aspect of Scottish Ale is the use of “Shilling” to categorize the various types of beer within Scotland. Denoted by the /- symbol and typically preceded by a number (60, 70, 80, or 90), “Shilling” beer is an indication of both strength and cost.
The Beer Duty levied in the 18th century on Scottish breweries impacted the ingredients they used. Heavy taxes on malt led the brewers to rely more on local resources such as peat for drying malt, which resulted in a distinctive peaty flavor profile for the Scottish Ales.

Styles and Categories
60/- Shilling Light Scottish Ale
60/- Shilling Light Scottish Ales, also known as Scottish Lights, are a type of Scottish ale with lower alcohol content and a lighter body. These ales typically have a malt-forward profile, with low hoppiness and full-bodied flavors. They often feature pale malt as their base and are less bitter than their heavier counterparts1.
Scottish Heavy Ale
Scottish Heavy Ale, or 70/- Shilling, is another category of Scottish ales with a slightly higher alcohol content than the 60/- Shilling Light Ales. These beers maintain the malt-centric focus of Scottish ales, but offer a more robust flavor profile. The increased alcohol content produces a richer, heartier beer that showcases a balance of malt sweetness and subtle hop character.
Scottish Export Ale
Scottish Export Ale, commonly referred to as 80/- Shilling, is a higher-alcohol variant of the standard Scottish ales. These ales are often characterized by a more robust maltiness and increased hop bitterness, offering a complex and satisfying drinking experience. With a bolder flavor profile and higher alcohol content, Scottish Export Ales showcase the variety and depth found within the Scottish ale style3.
Strong Scotch Ale
Strong Scotch Ale, also known as “Wee Heavy,” is a distinct category of Scottish ales that represent the boldest and most intense examples of the style. These beers are characterized by their high alcohol content, rich maltiness, and dark color. They often exhibit flavors of caramel, toffee, and dark fruits, with minimal hop presence. The focus in this category is firmly on the malt characteristics, making for a powerful and satisfying beer.
Ingredients and Profiles
Scottish Ales, known for their full-bodied nature and low hop profiles, typically feature a variety of malt and grain ingredients. Pale malt serves as the base, while additional malt varieties, such as crystal and biscuit malt, contribute to the flavor profile. The malt character is the backbone of Scottish Ales as it imparts caramel, toffee, and bready characteristics.
Water plays a significant role in the crafting of Scottish Ales, as the mineral content of the water used in brewing can enhance the malt nuances. A higher mineral content accentuates the maltiness while retaining a balanced taste.
In terms of hops, Scottish Ales use minimal amounts to keep the bitterness low. The International Bitterness Units (IBU) range is typically around 17-22, complementing the malt profile without overpowering it. A common hop choice for these ales is Kent Goldings, imparting subtle earthy and floral aromas to the beer.
Yeast selection is crucial in achieving the desired character of a Scottish Ale. Traditional Scottish Ales are fermented at relatively cold temperatures, resulting in low attenuation yeast levels. These ales also exhibit a higher final gravity, contributing to their full-body texture.
Barley is not as dominant in Scottish Ales compared to other beer styles but can still be present in some recipes. The use of barley can add a biscuit-like flavor, further enhancing the ale’s overall taste.
Malt Selection
When crafting a Scottish ale recipe, the importance of selecting the right malts cannot be overstated. Malt selection plays a critical role in determining the ale’s flavor profile, color, and mouthfeel. The base grain for a Scottish ale is typically a pale ale malt such as Maris Otter or Golden Promise. These English pale malts provide a solid foundation for the unique characteristics of a Scotch ale.
In addition to the base malt, a variety of specialty malts can be used to enhance the ale’s complexity and depth of flavor. Munich malt adds a rich, malty character to the beer, while chocolate rye and pale chocolate malts contribute chocolaty, roasted notes. Biscuit and Victory malts impart a subtle, toasty flavor, perfect for creating the warm and inviting profile of a Scottish ale.
Caramel malts are commonly included in the grain bill to increase the beer’s body, add sweetness, and develop a rich, caramel-like flavor. Roasted malts, such as chocolate, also find their place in Scottish ale recipes, bringing darker, more robust flavors to the mix. The careful balancing of caramel and roasted malts allows for a harmonious blend of flavors, characteristic of Scotch ales.
Yeast Selection
When brewing a Scottish ale, the choice of yeast is crucial to achieve the desired flavor profile. There are several strains of yeast that can be used to create an authentic Scotch beer, each having their own unique characteristics.
One popular option is White Labs WLP028 Edinburgh Scottish Ale yeast. This strain originates from Edinburgh, Scotland and is well-suited for brewing Scottish ales due to its low attenuation and production of restrained esters. These qualities lead to a malt-forward beer with a clean, smooth flavor.
Another suitable yeast strain is Wyeast 1728 Scottish Ale yeast, which is also known for its low attenuation and ability to create a clean, malty beer. Additionally, this strain has a higher tolerance for alcohol, making it a good choice for stronger Scotch ales.
For brewers who prefer using dry yeasts, both Safale S-04 and Wyeast 1084 are viable options. While these strains may not provide the exact same flavor profile as the liquid yeast options, they can still produce a delicious Scottish ale when used correctly.
Regardless of the yeast strain chosen, it is essential to maintain proper fermentation temperature throughout the process. Scottish ales typically ferment at cooler temperatures (50 – 60ºF) than other types of ales [^1^]. This allows for a slower, more controlled fermentation that contributes to the beer’s malty character and helps to minimize the production of unwanted flavors like diacetyl.
Hop Selection
When it comes to brewing a Scottish ale, the choice of hops plays a crucial role in determining the overall flavor profile and characteristics of the beer. While Scottish ales typically have a lower hop profile with a focus on malt character, it’s still essential to select the appropriate hops to create balance and impart the desired subtle notes.
Among the popular traditional hop varieties used in Scottish ales, Fuggle and East Kent Goldings stand out as excellent choices. Both are classic English hops that provide mild to moderate bittering and contribute earthy, floral, and slightly spicy notes. These hops work well in Scottish ales as they don’t overpower the malt flavors but rather help bring out the natural richness and complexity.
Target hops, another English variety, can also be considered for Scottish ale recipes. They provide higher bitterness levels while still maintaining a pleasant spicy, floral, and somewhat fruity aroma. This hop variety is particularly suitable for Scottish ales that call for more assertive bittering to achieve overall balance.
Continental European hops such as Hallertauer and Saaz could be utilized as well, especially when there’s a preference for more delicate and subtle hop characteristics. Hallertauer offers a mild bitterness with noble hop traits, such as soft floral notes. Saaz, on the other hand, contributes a very refined and subtle bitterness with a touch of spice.
Brewing Process
The brewing process for a Scottish ale begins with the mashing of grains, which traditionally involves one or two steps at higher temperatures, often above 160ºF. This high-temperature mash aids in the kettle caramelization process, crucial for developing the signature flavors found in Scottish ales1.
When the mashing is complete, the next step is boiling the wort. During this phase, hops are added to the brew, but Scottish ales are generally known for their low hop bitterness. Thus, the IBU (International Bitterness Units) is usually kept below 30.
Following the boil, a slow sparging process is performed to extract the residual sugars from the grains. After sparging, the wort is cooled, and yeast is added for the fermentation process.
Scottish ales are fermented at relatively low temperatures due to the colder climate of Scotland. This leads to a slower, more controlled fermentation that enhances the beer’s mouthfeel, creating a rich, full-bodied beer1.
During fermentation, the yeast consumes the sugar in the wort, converting it into alcohol and CO2. This process affects the original gravity (OG) and final gravity (FG) of the beer. Typical OG values for a Scottish ale range from 1.055 to 1.070, while the FG values tend to fall between 1.016 and 1.024.
Carbonation is another crucial factor to consider in the brewing process. Scottish ales are known for their lower levels of carbonation, resulting in a more smooth and silky mouthfeel.
As for clarity, Scottish ales may not be crystal clear due to the kettle caramelization process, but they generally possess a brilliant reddish or copper hue.
Recipe Guidelines
Scottish Ale is a flavorful and rich beer that has gained popularity in recent years. When crafting your own Scottish Ale, there are a few key guidelines that can help in producing a high-quality beer with the desired taste and appearance.
Begin by selecting a well-designed all-grain recipe that includes essential ingredients such as pale malt and specialty grains. Cara Pils malt can be added to enhance mouthfeel and head retention, while the use of a quality Scottish ale yeast will contribute to its authentic taste.
One important aspect of a Scottish Ale’s appearance is its color, measured in Standard Reference Method (SRM) units. Aim for an SRM value within the range of 17-34, depending on the specific style of the ale. You can find examples of different SRM values at scottish ale homebrew recipes.
When brewing, pay close attention to your water’s mineral profile. The right water chemistry can greatly impact the final taste of the ale. Long boil times of ninety minutes or more can help develop the malt-forward flavors characteristic of this style.
You may opt to use Irish moss, a clarifying agent, to improve the clarity of your beer. Add it to the boiling wort during the final fifteen minutes to achieve best results.
Keep in mind that hop presence in Scottish Ales should be minimal, allowing the malt flavors to take center stage. Select hops with low alpha acid percentages for bittering. Typically, a total of 15-30 International Bitterness Units (IBUs) is appropriate for most Scottish Ale styles.
To achieve the desired flavor profile, ensure that fermentation temperatures are carefully controlled. This allows the yeast to produce the distinctive esters and phenols commonly associated with Scottish Ales.
Craft Beer Impact
The emergence of craft beer has significantly influenced the brewing industry, including the traditional Scottish ale recipes. Craft beer enthusiasts often seek to create and enjoy unique and flavorful brews, and Scottish ales offer an exciting route for them to explore. The popularity of these malty, low-hop ales has prompted a resurgence in the market with many homebrewers and professional breweries alike developing innovative recipes to showcase Scottish ale’s versatility and complexity.
With the growth of craft beer culture, there is an increased focus on the ingredients used in Scottish ales. Historically, Scottish ales were brewed with local malt, often using Maris Otter, a classic British pale malt that provides a rich, biscuity backbone to the beer. Nowadays, the selection of high-quality ingredients, including specially roasted barley and various caramelized malts, can elevate a classic Scottish ale’s flavors and add more depth to the beer.
Additionally, the craft beer movement has invoked a renewed interest in experimenting with traditional techniques. For example, homebrewers typically implement kettle caramelization, a process where the wort is boiled for an extended time, allowing the sugars to caramelize and develop rich flavors that are synonymous with Scottish ales. These techniques contribute to the full-bodied and smooth character of the ale.
Craft beer’s impact can also be felt in the type of yeast used for brewing Scottish ales. Today’s brewers can choose from a variety of ale-specific yeast strains that impart different flavor profiles to the final product. A popular choice is the Scottish Ale yeast (Wyeast Labs #1728), which adds a clean, slightly fruity taste, further embracing the diverse flavors that Scottish ales have to offer.
Other Related Styles
Scottish ales are known for their distinct, malt-forward taste, with a range of styles and strengths. Among these, there are other styles which have similarities or connections to Scottish ale, such as Irish ale, strong ale, and sweet beer.
Irish ales, like Scottish ales, often feature a malt-forward profile. They tend to have a slightly lower alcohol content, with a focus on caramel and toffee flavors, balanced with a moderate hop presence. One of the most well-known Irish ale styles is the Irish red ale, characterized by its reddish-copper hue and toasty malt flavors.
Strong ales are a category that can encompass both Scottish and Irish ales when they reach higher alcohol levels. These beers are typically more robust and feature intense, complex flavors that can lean towards the sweeter side. Examples of strong ales within the Scottish and Irish categories include “wee heavy” Scotch ales and Strong Irish red ales.
Malt-forward beers are those that emphasize the malty flavors derived from grains used in the brewing process. Both Scottish and Irish ales, as mentioned earlier, prioritize malt character in their flavor profiles. This results in beers that highlight caramel, toffee, biscuit, and nutty notes without an excessive hop bitterness. Other malt-forward beer styles outside the Scottish and Irish realm include English Brown Ales, Belgian Dubbels, and Doppelbocks.
Sweet beer, on the other hand, mainly refers to beer styles that have a residual sweetness due to unfermented sugars left during the brewing process. While this characteristic is not exclusive to any particular style, it can be common to find sweeter flavor profiles in malt-forward and strong ales. Some examples of sweet beers are Milk Stouts, which contain lactose for added sweetness, and certain Barleywines, which balance their high alcohol content with residual sugar.
