How Was Beer Made in the 18TH Century?


Imagine you’re a brewer in the 18th century, tasked with turning simple ingredients into a satisfying pint. You’d start with barley, soaking and germinating it before drying it in a kiln to preserve essential enzymes.

Next, you’d mash the malted barley in hot water to extract the sugars, setting the stage for fermentation. Boiling the wort with hops would add bitterness, aroma, and preservative qualities.

The fermentation process, often conducted in open vats, required careful monitoring. Ever wondered what challenges and innovations defined this ancient craft?

Ingredients and Raw Materials

In the 18th century, beer was primarily made from malted barley, yeast, water, hops, and occasionally molasses or honey. These ingredients were the cornerstone of the brewing process and essential for creating the diverse beer styles of the era.

Malted barley was the main grain used, providing necessary sugars for fermentation. By germinating and drying the barley, brewers converted its starches into fermentable sugars, a crucial step in brewing.

Water quality significantly impacted the beer’s final taste, with brewers often sourcing water from local wells or rivers, each imparting unique characteristics to the brew.

Hops, added during the boiling stage, contributed flavor and bitterness, balancing the malt’s sweetness. While not as universally used as today, hops were valued for their preservative qualities.

Yeast played a critical role in fermentation, converting sugars into alcohol and carbon dioxide. Brewers typically sourced yeast from previous batches or relied on wild yeast present in the environment.

Occasionally, molasses or honey was added for additional flavor and fermentable sugars, further diversifying the beer’s profile.

Malting Process

Malting Process

The malting process transforms raw barley into malt, which provides the essential fermentable sugars needed for brewing beer. In the 18th century, this process began with soaking barley in water to initiate germination. This germination stage was crucial for enzyme development, necessary for breaking down the barley’s starches into fermentable sugars.

After soaking, the barley was allowed to sprout and was then spread out on malting floors to control moisture and temperature, ensuring optimal enzyme development. The germinated barley, known as green malt, was subsequently dried in a kiln to halt the germination process. This drying phase was vital for preserving the enzymes and reducing moisture content, making the malt stable for storage.

The 18th-century malting process required meticulous attention to detail, encompassing several key steps:

  • Soaking: Initiating germination by soaking barley in water.
  • Germination: Controlled sprouting to develop essential enzymes.
  • Kilning: Drying green malt to stop germination and preserve enzymes.
  • Monitoring: Constant observation of temperature and moisture levels.

This method ensured the production of high-quality malt essential for brewing.

Mashing and Lautering

Mashing and Lautering

Once your malt is ready, mashing begins by soaking the grains in hot water to extract the sugars necessary for fermentation. In the 18th century, brewers often used brown malt, which contributed a distinct flavor and color to the beer. During mashing, the malt is mixed with hot water in a mash-lauter tun. This process converts the starches in the grains into fermentable sugars, creating a thick, porridge-like mixture.

After mashing, the next step is lautering, which separates the liquid wort from the solid grain husks. The mash-lauter tun is drained, allowing the liquid wort to filter through the grain bed. This wort contains the essential sugars that yeast will later ferment into alcohol.

During lautering, the wort is carefully collected to ensure it’s free from unwanted solids. Lautering is crucial to the brewing process because it affects the quality and clarity of the wort. Any remaining grains are rinsed with additional hot water to extract every last bit of sugar.

Once lautering is complete, the wort is ready for the next step: boiling with hops, a phase that adds flavor and bitterness to the beer.

Boiling With Hops

Boiling With Hops

Boiling the wort with hops is essential for infusing beer with flavor, bitterness, and aroma, resulting in a balanced and well-preserved brew. In the 18th century, brewers meticulously added hops during the boiling stage for several critical reasons.

Firstly, hops balanced the malt’s sweetness, creating a more complex and enjoyable flavor profile.

Secondly, the boiling process extracted bittering compounds and aromatic oils from the hops, which were vital for the beer’s taste and aroma.

Moreover, hops acted as a natural preservative, preventing spoilage and extending the beer’s shelf life in an era without modern refrigeration and pasteurization. This preservation was crucial for ensuring the beer remained fresh over time.

Here are the key reasons why boiling with hops was indispensable in 18th-century brewing:

  • Flavor Balance: Hops counteracted the malt’s sweetness with necessary bitterness.
  • Aroma: Boiling released essential aromatic oils from the hops.
  • Preservation: Hops served as a natural preservative, extending the beer’s shelf life.
  • Consistency: The process ensured uniform extraction of bittering compounds.

Understanding the role of boiling with hops illuminates the intricacies of 18th-century beer making and underscores the importance of each brewing step.

Fermentation Techniques

Understanding 18th-century fermentation techniques reveals how brewers utilized yeast to convert sugars into alcohol and carbon dioxide, ensuring each batch of beer developed the desired flavors and characteristics. Fermentation was a vital step in the brewing process.

Brewers predominantly employed open vat brewing, where yeast from previous batches or the environment would naturally inoculate the wort. Open-topped barrels were standard, allowing the yeast to thrive and initiate fermentation.

Proper yeast management was crucial. Brewers meticulously handled their yeast, often skimming it off the top of fermenting wort for reuse in future batches. This practice not only ensured successful fermentation but also maintained the consistency of the beer’s flavor profile. Without modern refrigeration or pure yeast cultures, brewers had to be highly attentive to how yeast influenced their beer.

While the science behind yeast’s role in fermentation wasn’t fully understood, brewers knew that successful fermentation resulted in the desired alcohol content and carbonation. By mastering these techniques, 18th-century brewers produced quality beer that satisfied contemporary tastes, laying the foundation for modern brewing practices.

Conditioning and Storage

Conditioning and Storage

After fermentation, 18th-century brewers conditioned and stored their beer in wooden barrels or bottles to allow the flavors to mature and develop. This conditioning phase was crucial for the beer’s taste profile to deepen as it aged. Wooden barrels were particularly favored because they could impart unique flavors to the beer and aid in the aging process, resulting in a smoother and more complex beverage.

To ensure the beer maintained its quality, brewers typically stored it in cellars or other cool, dark spaces. These conditions facilitated proper aging without the risk of spoilage. Even small beer, a weaker brew consumed daily, underwent conditioning but for a shorter period due to its quick turnaround.

Proper storage was vital for several reasons:

  • Flavor Development: Wooden barrels contributed unique flavors as the beer aged.
  • Temperature Control: Cool, dark storage spaces prevented spoilage.
  • Wood Fire Impact: The heat from wood fires used in brewing could influence storage conditions.
  • Small Beer: Even lower-alcohol beers required careful conditioning.

Understanding the conditioning and storage processes highlights the meticulous care 18th-century brewers invested in their craft. These steps ensured that every pint, whether a strong ale or small beer, was flavorful and enjoyable.


In the 18th century, brewing beer began with malting barley, which involved soaking and drying the grains to activate essential enzymes.

The malt was then mashed in hot water to extract fermentable sugars. This mixture, known as wort, was boiled with hops to add flavor and act as a preservative.

Fermentation typically took place in open vats using natural yeast to achieve the desired alcohol content.

The beer was then conditioned and stored properly to ensure quality and taste.
