Guinness Beer: Kosher Certification And Jewish Drinking Traditions

Kosher dietary laws are a very important part of everyday life for observant Jews. Kosher food and drink are those that are fit for consumption according to traditional Jewish law. Beer can be kosher, but it must be inspected and certified by a certifying body.

The rules for what makes a beer kosher can change depending on the ingredients, additives, and flavourings used. Beers with higher alcohol content that require fermentation with non-standard yeasts also require certification.

Guinness is a dry stout, and according to Rabbi Yair Hoffman, it does not contain any dairy products. However, a Smithsonian article has revealed that Guinness uses isinglass, which involves mixing fish collagen into the beer. The collagen usually comes from non-kosher fish, such as sturgeon. This has led to questions about whether Guinness is still kosher.

Guinness uses isinglass, a gelatine-like substance made from fish bladders

For many years, Guinness used isinglass, a gelatine-like substance made from fish bladders, in the production of its beer. Isinglass is a traditional finings agent, derived from the swim bladders of certain tropical and subtropical fish, including sturgeon. It is added to cask beers to help any remaining yeast and solid particles settle out of the final product, creating a clear beer.

The use of isinglass in beer production dates back centuries, with records showing that it was imported into Britain from Russia as early as 1761. The collagen in isinglass causes yeast to precipitate out of suspension, leaving the beer clear. This process is known as flocculation, and it is a cheaper way to control this process and produce clear beer.

The swim bladder of the fish is macerated and dissolved for several weeks in dilute food-grade acids, forming a turbid, colorless, viscous solution largely made up of collagen. This solution is then added to the beer, where it attracts particles in the fermented beer that create an unwanted "haziness". The isinglass and these particles then form a jelly-like mass that settles to the bottom of the cask, leaving a clear beer above.

While the use of isinglass is a well-established technique for clarifying beer, it has come under scrutiny in recent years due to its animal-derived source. In response to consumer pressure, Guinness announced that it was working to avoid using key animal byproducts like isinglass. There are now alternative fining agents on the market that are vegan-friendly, and some brewers have chosen to stop using isinglass altogether.

Isinglass is used to help yeast and solid particles settle out of the beer

Isinglass is a form of collagen obtained from the dried swim bladders of fish. The word comes from the obsolete Dutch 'huizenblaas', or German 'Hausenblase', both meaning 'sturgeon bladder'. The bladders are removed from the fish, processed, dried, and formed into various shapes for use.

In the context of beer, isinglass is used as a fining agent to help yeast and solid particles settle out of the beer. Specifically, it acts as a flocculant, causing yeast and proteins to precipitate out of suspension and leave the beer clear. This process is known as fining or clarification and is particularly important for cask-conditioned beers.

When added to beer, isinglass forms a jelly-like mass that attracts particles in the fermented beer, such as yeast, creating an unwanted "haziness". This mass then settles to the bottom of the cask, and can be removed. While beer will eventually clear on its own, isinglass speeds up this process without affecting the final flavour of the beer once removed.

Isinglass is especially useful for removing haze-forming particles that other fining agents, such as carrageenan (derived from Irish moss), cannot address. However, its use has declined in recent years due to the advancement of centrifugation and filtration technologies, as well as a growing demand for vegan-friendly beers.

The most common source of isinglass is the non-kosher sturgeon

Isinglass is a form of collagen obtained from the dried swim bladders of fish. The word comes from the obsolete Dutch 'huizenblaas', with 'huizen' meaning a kind of sturgeon and 'blaas' meaning bladder. The English word may also derive from the German 'Hausenblase', which means the same thing. The bladders are removed from the fish, processed, dried, and formed into various shapes for use.

Sturgeon is a non-kosher fish. According to Jewish law, for fish to be considered kosher, they must have fins and easily detached scales. The scales of a sturgeon are extremely hard to remove.

Isinglass is widely used in the production of kosher wines, but due to the kashrut, it is not derived from the beluga sturgeon. Whether the use of a non-kosher isinglass renders a beverage non-kosher is a matter of debate in Jewish law.

The most common source of isinglass historically was the non-kosher sturgeon, especially the beluga sturgeon. In 1795, an invention by William Murdoch facilitated a cheap substitute using cod, which was extensively used in Britain instead of Russian isinglass. In modern British brewing, all commercial isinglass products are blends of material from a limited range of tropical fish.

Guinness is kosher in some parts of the world, but not in the US

The kosher status of Guinness beer is a complex issue that has been the subject of much debate within the Jewish community. While some kosher agencies have previously accepted Guinness as kosher, its use of certain ingredients and production methods has raised questions about its compliance with Jewish dietary laws, known as kashrut.

Guinness beer is a dry stout, which is a darker and sweeter variation of regular beer. One of the key ingredients in stout beers is lactose, a sugar derived from whey, a dairy product. According to Jewish law, or halacha, anything that comes from milk is considered milchig, and consuming it with meat is forbidden. This presents a problem for those who follow the custom of waiting between consuming dairy and meat products, known as fleishig.

While lactose itself may not be an issue according to some interpretations, Guinness has also been reported to use isinglass, a substance made from the air bladders of fish, during the brewing process. Isinglass is often made from non-kosher fish, such as sturgeon, and its use has sparked concerns about the kosher status of Guinness beer.

Despite these concerns, Guinness bottled beer sold in the US is brewed in Canada by Labatt's, and it has been reported that the famous Guinness brewery in Dublin is under the supervision of the Irish Rabbinate. Additionally, both Guinness and Murphy's beers are kosher-certified in some parts of the world, and the recipe is said to be the same everywhere.

In summary, while Guinness beer may be considered kosher in some regions, it appears that the use of certain ingredients and production methods has led to debates about its kosher status, particularly in the US. The interpretation of Jewish dietary laws and the evaluation of specific ingredients can vary, resulting in differing opinions on the kosher status of certain foods and beverages, including Guinness beer.

Kosher beers are labelled with a mark called a hekhsher

Kosher certification agencies have differing opinions on whether Guinness is kosher. Some agencies, such as Star-K, previously specified that "All unflavored Heineken, Guinness, and Corona are kosher". However, Guinness uses isinglass, a gelatine-like substance made from the air bladders of fish, which is usually from non-kosher fish such as sturgeon, in its beer. This has brought into question whether Guinness is still kosher.

The hekhsher symbol serves as a quick and easy way for consumers to identify if a beer is kosher or not. It is important to note that not all kosher beers may have a hekhsher, as some smaller breweries or craft beers may not have undergone formal kosher certification. In such cases, consumers may need to refer to other sources of information, such as online kosher databases or by contacting the brewery directly, to determine if a particular beer is kosher.

The process of obtaining a hekhsher involves an inspection of the ingredients, production methods, and facilities used to produce the beer. The certifying agency will ensure that the beer complies with kosher laws, including the exclusion of non-kosher ingredients, proper handling and preparation of ingredients, and the separation of dairy and meat products. The agency may also require regular audits and inspections to maintain the kosher certification.

It is important to note that the requirements for kosher certification may vary depending on the specific interpretations and standards of the certifying agency. Some agencies may have more stringent requirements than others, and it is up to the consumer to decide which agency's standards they prefer to follow.
