Guinness Beer's Ph Mystery: Acidic Or Not?

Guinness is a popular stout beer that originated in Ireland in the 18th century. It has a distinctively creamy texture and a rich flavour, which has made it a favourite among beer enthusiasts worldwide. One unique characteristic of Guinness is its perceived smoothness, which can be attributed to its low carbonation and the use of nitrogen during the brewing process. This also results in a less acidic taste compared to other beers. The question of whether Guinness is acidic or not is an interesting one, as some people find it gentler on the stomach than other beers, while others consider it to be equally or more acidic.

Guinness is less acidic than other beers due to its low carbon dioxide content

Guinness beer is less acidic than other beers, and this can be attributed to its relatively low carbon dioxide content. While most beers are carbonated using only carbon dioxide, Guinness is unique in that it is carbonated with a blend of both carbon dioxide and nitrogen. This blend is responsible for the tiny bubbles, creamy head, and smooth, mellow finish characteristic of Guinness.

The carbonation process in beer typically involves infusing carbon dioxide into the liquid, resulting in the formation of bubbles and a crisp, bitter taste. However, Guinness's use of nitrogen results in smaller, more delicate bubbles, contributing to its signature smooth texture. This difference in carbonation methods leads to a variation in the acidity levels of Guinness compared to other beers.

Nitrogen plays a crucial role in the distinct characteristics of Guinness. The nitrogen and carbon dioxide mixture is carefully combined and pressurised in kegs, resulting in the creamy head and cascading bubbles that Guinness is known for. This blend also contributes to the sweeter and more mellow flavour profile of the beer.

The use of nitrogen in Guinness has a significant impact on its acidity levels. Nitrogen produces smaller bubbles compared to carbon dioxide, which leads to a smoother and less acidic beer. The presence of nitrogen also influences the mouthfeel of Guinness, making it velvety and rich on the palate.

Additionally, the lower carbon dioxide content in Guinness affects the taste and overall drinking experience. Carbon dioxide is known to contribute to a crisp and bitter flavour profile typically associated with beers carbonated solely with carbon dioxide. By reducing the amount of carbon dioxide, Guinness achieves a sweeter and fuller-bodied taste, further differentiating it from other beers.

It is also less fizzy, which makes it easier on the stomach

Guinness beer is known for its distinctively creamy mouthfeel and signature head. This is achieved through a blend of carbon dioxide and nitrogen gas, with the nitrogen creating smaller bubbles that are far less soluble than carbon dioxide. The result is a slightly under-carbonated ale with a creamy head.

The use of nitrogen gas in Guinness beer also contributes to its reputation for being easier on the stomach than other beers. While all beers contain carbonation, Guinness has a lower level of carbonation due to its higher ratio of nitrogen to carbon dioxide. This lower level of carbonation can make Guinness more tolerable for those with stomach sensitivities or issues such as GERD, who might otherwise struggle with highly carbonated beverages.

In addition to its lower carbonation, Guinness is also lower in alcohol content than many other beers, with an ABV of 4.3%, while popular lager beers in the US typically have an ABV of 5% or higher. The lower alcohol content contributes to Guinness being lower in calories, which can also make it easier on the stomach.

The unique characteristics of Guinness beer, including its nitrogenation, lower carbonation, and lower alcohol and calorie content, all contribute to its reputation for being a gentle and smooth beer that is well-tolerated by those who might experience stomach discomfort from other types of beer.

Guinness has fewer calories than skim milk or orange juice

Guinness Beer is often associated with being a heavy drink due to its dark colour. However, it is lower in calories than skimmed milk, orange juice, and many popular beers. A pint of Guinness has approximately 198 calories, which is less than the number of calories in a pint of orange juice or skimmed milk.

The reason behind this is that alcohol is the main source of calories in any alcoholic beverage. Guinness is 4.3% ABV, whereas most popular lager beers in the US are at least 5%. Thus, a Guinness will naturally be lower in calories than a beer containing 5% or more alcohol, even though it might seem more filling.

The nitrogenation process used by Guinness, which pairs nitrogen gas and carbon dioxide, gives the beer its iconic velvety texture. This is similar to how drinking nitro cold brew is smoother than a regular cup of cold brew coffee, making it seem more filling without adding any extra calories.

The perception of Guinness as a heavy drink may also stem from its advertising campaigns. In the past, Guinness has used slogans such as "Guinness for Strength" and "Guinness is Good for You", which contributed to the idea that the beer is rich and nutritious. While Guinness does contain some antioxidants, B vitamins, fibre, and prebiotics, it is important to note that most health organisations advise against starting to drink alcohol for the sake of longevity.

In conclusion, while Guinness may have a richer mouthfeel and be perceived as a heavy drink, it actually has fewer calories than skim milk or orange juice. However, it is always important to consume alcoholic beverages in moderation and be mindful of their calorie content.

It is associated with a decreased risk of cardiovascular disease

While Guinness is an alcoholic beverage and excessive drinking is associated with many health problems, moderate consumption of alcohol is linked to a decreased risk of cardiovascular disease. According to a 2021 review in Nutrients, moderate beer consumption—defined as up to one beer per day for women and two per day for men—is associated with a reduced risk of cardiovascular disease and overall mortality.

The health benefits of moderate alcohol consumption have been debated, with some experts claiming that it can be beneficial, while others have questioned these benefits. However, it is important to note that the 2021 review in Nutrients is not an isolated finding, and other studies have supported the idea that moderate drinking may have positive effects on cardiovascular health. For example, a 2019 study found that moderate drinking—one drink per day for women and two drinks per day for men—reduced the risk of heart attack or dying from cardiovascular disease.

The key nutrients in Guinness that may contribute to these health benefits are antioxidants, B vitamins, fiber, and prebiotics. Bamforth, a brewing expert, states that Guinness is one of the richer sources of these nutrients among beers. The polyphenols from barley and hops in beer have been shown to lower cholesterol, reduce the risk of heart disease, and protect against free radicals. Additionally, the nitrogenation process used by Guinness gives the beer its velvety texture without adding extra calories.

While the health benefits of moderate drinking may be debated, it is essential to consider the risks associated with excessive alcohol consumption. Excessive drinking can lead to liver damage, cancer, decreased brain function, and other health problems. It is also important to note that certain individuals should avoid alcohol entirely, such as pregnant women, people under the age of 21, and those with specific health conditions or medications that interact with alcohol.

Guinness is suitable for vegans and vegetarians

Guinness is now officially vegan and suitable for vegans and vegetarians in draft, bottle, and can form. This change came about after Guinness changed its filtration process, removing isinglass, a collagen product made from fish bladders, which was previously used to remove extra yeast from the stout during the fining process.

In 2015, Guinness's parent company, Diageo, announced it would be implementing a new filtration system to eliminate isinglass from the manufacturing process to make Guinness suitable for vegans. In April 2016, Diageo confirmed that all kegs of Guinness on the market were vegan-friendly. Finally, in 2018, Diageo confirmed that all Guinness products worldwide, including Guinness Draught, Guinness Extra Stout, and Guinness Foreign Extra Stout, are now isinglass-free and suitable for vegans.

The popular stout drink is famous for its deep ruby-red colour and signature foamy white top. Guinness is made from four main ingredients: roasted and malted barley, hops, water, and yeast. Its creamy white head is formed when the beer is poured, causing bubbles of nitrogen and carbon dioxide gas to surge, resulting in the frothy topping.

Guinness has a rich history, having been brewed for over 260 years and is now manufactured in five countries worldwide. It is one of the world's most popular drinks, with 10 million pints consumed daily and 1.5 billion pints enjoyed annually.
