Guinness Ipa Beer: Gmo And Chemical Mystery Solved

Guinness has been brewing beer for over 250 years, and in that time, it has expanded its range beyond its original stout. One such expansion is into the world of IPAs, with the Guinness Nitro IPA and Guinness Hop House 13. While the company has shown a dedication to innovation, it is unclear what specific chemicals or GMOs are present in their beers. However, with a focus on flavour and exceptional beers, it is likely that Guinness uses a variety of ingredients and processes to create their unique brews.

High Fructose Corn Syrup

Some sources claim that Guinness IPA contains HFCS, while others refute this claim. It is important to note that Guinness has not explicitly disclosed the presence of HFCS in their beer. However, they have stated that their beer contains barley, hops, yeast, and water, with no mention of corn or corn-derived products.

The origin of the claim that Guinness IPA contains HFCS may stem from the use of corn syrup in the brewing process. Corn syrup is a common source of fermentable sugar used by brewers to feed the yeast and promote fermentation. While it is possible that Guinness uses corn syrup in their brewing process, it is unlikely that HFCS is present in the final product. This is because the yeast consumes the sugars during fermentation, converting them into ethanol and carbon dioxide.

The absence of HFCS in Guinness IPA is further supported by the fact that Guinness has taken steps to remove corn-derived products from their brewing process. In recent years, they discontinued the use of isinglass, a fining agent made from fish bladders, to make their beer suitable for vegetarians and vegans. This change demonstrates Guinness's commitment to transparency and accommodating diverse consumer preferences.

In conclusion, while there may be speculation about the presence of HFCS in Guinness IPA, there is no concrete evidence to support this claim. The brewing process and ingredients used by Guinness suggest that HFCS is unlikely to be present in their beer. As such, consumers can make informed choices based on their preferences and ethical considerations.

Isinglass (fish bladder)

Isinglass, also known as fish glue, is derived from the swim bladders of certain types of fish. The word 'isinglass' comes from the Dutch term 'huizenblaas', where 'huizen' refers to a type of sturgeon and 'blaas' means bladder. It is a form of collagen that has been used for centuries as a fining or clarifying agent in alcoholic beverages. Finings are substances that are added to beer to remove particles such as yeast and protein solids, resulting in a clearer and more visually appealing beverage.

In the context of beer-making, isinglass is typically derived from the swim bladders of tropical and subtropical fish, such as sturgeon or Nile Perch from Lake Victoria. The swim bladders are sun-dried and then packed for export to markets, primarily in China and the UK. In China, it is used to make fish maw soup, while in the UK, it is used to make isinglass finings for beer.

The use of isinglass in beer involves macerating and dissolving the swim bladders in dilute food-grade acids for several weeks. This process forms a turbid, colorless, viscous solution largely composed of collagen, known as isinglass finings. When added to beer, isinglass causes yeast and other suspended particles to clump together through electrostatic interaction, forming larger formations that can be easily removed by brewers. This process results in a clearer and more aesthetically pleasing beer.

Isinglass has been traditionally used in cask ales (also called cask-conditioned beer), which are unfiltered and unpasteurized brews served straight from the cask. However, its use has declined in recent years due to advances in centrifugation and filtration technologies. Today, isinglass is mainly confined to cask ales in the UK and some craft brewers who use it to clarify their beer without filtration.

The presence of isinglass in beer has been a concern for vegetarians and vegans, as it is an animal-derived product. While very little isinglass may remain in the final beer product, its use in the brewing process is enough to render the beer non-vegetarian. As a result, there has been a push for brewers to explore alternative finings that are vegan-friendly, such as bentonite, seaweed, or Irish moss. Some breweries, like Green's, have chosen to avoid using isinglass altogether, prioritizing taste and a natural brewing process over the quicker turnaround time that isinglass provides.

Nitrogen

The "widget" in Guinness cans and bottles is a small plastic ball containing nitrogen, which activates and mixes the gas with the beer when opened. This innovation by Guinness has transformed the texture and flavour of the beer, making it a fundamental part of the drinking experience. The perceived smoothness of draught Guinness is a result of its low level of carbon dioxide and the creaminess of the head caused by the fine nitrogen bubbles and the dispensing method.

Carbon Dioxide

The use of carbon dioxide in beer dates back to the early days of brewing. Brewers would use carbon dioxide to carbonate the beer, giving it a sharp, bitter taste. Over time, brewers experimented with different levels of carbonation to create a range of beer styles, from light and crisp lagers to bold and robust stouts.

Guinness, known for its smooth and creamy texture, was one of the first beers to use nitrogen instead of carbon dioxide. Nitrogen bubbles are smaller than carbon dioxide bubbles, resulting in a smoother and less acidic taste. This change was first introduced in 1959 by mathematician-turned-brewer Michael Ash, who discovered a way to infuse the beer with nitrogen without making it fizzy.

The addition of carbon dioxide to beer can be done in several ways. One common method is to force the beer through a plate with fine holes, creating friction and forming small bubbles. Another method is to use a "widget", a small plastic ball containing nitrogen, that is placed inside the beer can or bottle. When the can or bottle is opened, the nitrogenated beer is released, creating a foamy head and a smooth mouthfeel.

While carbon dioxide is a natural byproduct of the fermentation process, brewers often add additional carbon dioxide to enhance the flavour and mouthfeel of the beer. This can be done through a process called force carbonation, where the beer is sealed in a keg or bottle with additional carbon dioxide.

In recent years, there has been a growing trend towards low-carbonation or even flat beers, such as traditional English-style cask ales. These beers have a softer mouthfeel and allow the subtle flavours of the malt and hops to come through. However, most mass-market beers still rely on carbonation to provide a crisp, refreshing taste.

Barley

Guinness beer is made from a variety of ingredients, including water, barley, roast malt extract, hops, and brewer's yeast. The barley used in Guinness is sourced from Irish barley farmers, with whom the company is working to transition towards regenerative agriculture. This involves adopting practices that use nature-based solutions to produce low-carbon barley and improve biodiversity and water resources.

In addition to malted barley, Guinness also uses unmalted barley, which was introduced in the mid-20th century. The unmalted barley adds a sharp lactic acid flavour to the beer. The combination of malted and unmalted barley gives Guinness its unique flavour profile.

The use of barley in the brewing process is a traditional method that has been used for centuries. It is an essential component in creating the distinct taste, aroma, and appearance of Guinness beer. The roasting process of the barley can be adjusted to create different flavour profiles, allowing for experimentation and the creation of new varieties of Guinness, such as the IPA.

The company's commitment to using high-quality barley and its collaboration with Irish farmers to promote sustainable practices ensures the consistency and quality of Guinness beer. The barley is carefully selected and processed to meet the specific requirements of the brewing process, contributing to the overall success and popularity of the brand.
