A blue beer is a unique and visually striking beverage that has gained popularity in recent years. It is created by adding a natural blue pigment derived from spirulina algae during the brewing process. This algae, commonly known as spirulina, is grown in basins by a company called Etika Spirulina in northern France. The specific component of spirulina that gives the blue color is called phycocyanin.
As a sommelier and brewer, I have had the opportunity to taste and study various types of beers, including blue beers. The addition of spirulina to beer not only gives it a vibrant blue hue but also adds a subtle earthy flavor. It is fascinating how this natural ingredient can transform the appearance and taste of a traditional beer.
One of the key reasons why spirulina is used to create blue beer is its rich nutritional profile. Spirulina is packed with vitamins, minerals, and antioxidants, making it a popular superfood. By incorporating spirulina into beer, brewers are able to offer a visually appealing product that also provides some potential health benefits. However, it is important to note that the concentration of spirulina in blue beer is typically quite low, so its nutritional impact may be minimal.
The process of adding spirulina to beer involves careful consideration and experimentation by the brewer. The spirulina extract, containing the phycocyanin pigment, is typically added during the fermentation stage of brewing. This allows the pigment to blend with the beer and create the desired blue color. The amount of spirulina used can vary depending on the brewer's preference, and it may require some trial and error to achieve the perfect shade of blue.
It is worth mentioning that the blue color of spirulina beer can vary in intensity. Some brewers may opt for a lighter, sky-blue hue, while others may aim for a deeper, navy blue tone. This variation in color adds to the artistic and creative aspect of blue beer production.
The taste of blue beer can vary depending on the base beer style and the additional ingredients used. Some brewers may choose to create a blue version of a classic beer style, such as a blue lager or blue ale, while others may experiment with more unconventional flavors. The spirulina itself adds a subtle earthy note to the beer, which can complement certain beer styles and enhance the overall drinking experience.
In addition to its unique appearance and flavor profile, blue beer can also be a great conversation starter and a way to add a fun twist to social gatherings or special occasions. Its eye-catching blue color is sure to intrigue and captivate beer enthusiasts and casual drinkers alike.
To summarize, a blue beer is a visually striking beverage created by adding spirulina algae, specifically the phycocyanin pigment, during the brewing process. This natural ingredient not only gives the beer a vibrant blue hue but also adds a subtle earthy flavor. The concentration of spirulina is typically low, and the taste can vary depending on the base beer style and additional ingredients. Blue beer offers a unique and creative drinking experience, making it a popular choice for those looking to try something out of the ordinary.
