As an expert sommelier and brewer, I can provide you with a detailed answer to your question about who makes the Kirkland Citra Hop Session IPA. It is important to note that Kirkland is a private label brand owned by Costco, and they contract with different breweries to produce their beers.
In the case of the Kirkland Citra Hop Session IPA, it is believed to be produced by Matt Brewing Company, also known as Saranac Brewery. Matt Brewing is located in Utica, New York, and has been in operation since 1888. They have a long history of brewing quality craft beers and have gained a good reputation in the industry.
However, it is worth mentioning that Costco has also contracted with other breweries to produce their Kirkland beers. One of these breweries is Gordon Biersch, which also operates under the name Hopfen Und Malz Brewing Co. Gordon Biersch is a well-known brewery with locations across the United States, and they have been brewing craft beers since 1988.
The reason for Costco's partnership with multiple breweries is likely due to their large distribution network and the need to supply their stores on opposite sides of the country. By working with multiple breweries, Costco can ensure that their Kirkland beers are readily available in their stores nationwide.
It is important to note that while the Kirkland beers are produced by these breweries, they are not simply rebranded versions of the breweries' own beers. The Kirkland beers are unique recipes created specifically for Costco, and they are made to meet the specifications and standards set by the company.
In my personal experience, I have tried various Kirkland beers and have found them to be of good quality and enjoyable. While they may not have the same level of complexity and uniqueness as some craft beers from smaller breweries, they are still a great option for those looking for affordable and accessible beers.
To summarize, the Kirkland Citra Hop Session IPA is believed to be produced by Matt Brewing Company, also known as Saranac Brewery. However, Costco also contracts with other breweries such as Gordon Biersch to produce their Kirkland beers. These partnerships allow Costco to distribute their beers to stores across the country and provide customers with a range of options at affordable prices.
