Guinness Yeast: Uncovering The Secret To Ireland's Iconic Beer

Guinness is a traditional Irish stout beer made from barley, hops, water, and a specific strain of ale yeast. The yeast has been used for over 125 years and is now often simply called Guinness yeast.

Guinness yeast strain used for over 125 years

Guinness is a traditional Irish stout beer made from barley, hops, water, and a specific strain of ale yeast. The yeast has been used for over 125 years and is now often simply called "Guinness yeast". The deep color and caramelized flavor that are characteristic of Guinness come from barley that has been roasted but not malted. The dark ale is known for its dense, creamy head, which is achieved by mixing the beer with nitrogen to create smaller bubbles that result in a thicker head.

The present yeast used to make Guinness stout brewed in Dublin, Ireland, can be traced back to 1903, but its origins are unknown. A genomic analysis of 22 S. cereviseae yeast strains used in beer brewing suggests that yeast used to brew Guinness form a distinct evolutionary sub-clade, and that the modern-day Guinness yeast is closely related to the 1903 Watling Laboratory Guinness yeast.

Brewer’s yeast (Saccharomyces cerevisiae) is an essential component of beer production. During fermentation, these microorganisms convert sugars from malt into alcohol and carbon dioxide. Using different strains of this yeast can result in different types of beer, such as stouts or lagers, and can even influence its flavour profile.

The dark ale is known for its dense, creamy head, which is achieved by mixing the beer with nitrogen to create smaller bubbles that result in a thicker head. Guinness is one of the most successful beer brands worldwide.

The original recipe for Guinness did not include yeast, which is uncommon in the beer world, which is overrun by science, branding, and everything niche. The book and its recipes reveal just how unscientific the company was at its inception. The book describes ground malt before the idea of it existed and mentions hops without much of an understanding of their taste. Today, hops are king of the craft beer game, and brewers and enthusiasts alike not only know all about the different varieties, but view the differences in varieties as crucial in determining flavor.

Guinness deep colour and caramelised flavour from roasted barley

Guinness is a traditional Irish stout beer made from barley, hops, water, and a specific strain of ale yeast called Guinness yeast. The deep colour and caramelised flavour that are characteristic of Guinness come from barley that has been roasted but not malted. The long-time traditions of Guinness have not hindered progress but have helped improve it. The roasting process of the barley transforms the barley's natural starches into various flavour and colour compounds. The longer and hotter the roasting process, the darker the barley becomes. The roasted barley used in Guinness is responsible for the beer's deep, dark shade, which can range from a deep ruby red to a near-black hue. This colour is a defining characteristic of the beer and has become synonymous with the Guinness brand.

Guinness is a traditional Irish stout beer made from barley, hops, water, and a specific strain of ale yeast. The yeast has been used for over 125 years and is now often simply called "Guinness yeast". The deep color and caramelized flavor that are characteristic of Guinness come from barley that has been roasted but not malted. The dark ale is known for its dense, creamy head, which is achieved by mixing the beer with nitrogen to create smaller bubbles that result in a thicker head.

The process of using this gas mix in draught systems is what gives Guinness its trademark appearance and flavor profile. Nitrogen plays a crucial role in this process, providing smaller bubbles that create a creamy head and a smooth taste. On the other hand, carbon dioxide helps to maintain just the right amount of carbonation in the beer, balancing the effects of nitrogen.

The company relies on a mixture of 75% nitrogen and 25% carbon dioxide, which helps create the smooth and dense foam that Guinness is known for. Maintaining the correct gas pressure is crucial. Regulators should be set between 30-38 PSI, which ensures the beer pours smoothly, without over-carbonating. Additionally, keeping the beer at the right temperature, typically around 38-42°F, is important for flavor and foam quality. Glass angle during the pour can also affect the head. Holding the glass at a 45-degree angle helps control foam formation.

The Guinness Storehouse and Open Gate Brewery in Dublin, Ireland, offers a look into the history of Guinness and beer in general. The book provides a spectacular look into the history of Guinness and beer in general. “What’s really interesting about this book is the age of it—the fact that we actually have brewing recipes going back to that date,” Colgan said.
