What brand of beer is available in a bottled or canned format?

Guinness is widely known for its signature stout, which is available in both bottled and canned formats. This iconic beer has a long history and is well-distributed, making it a common choice in many bars and restaurants, as well as for retail purchase. Bottled Guinness comes in various styles, with the Original and Draught versions being particularly popular. The canned options, especially with the unique nitrogen widget that helps replicate the draft experience, are also well-received by consumers. This availability in multiple formats makes Guinness a versatile choice for different preferences, aligning with the question asked.

In contrast, while styles like Epic IPA, Four Winds Pale Ale, and Russel Hazy IPA may also be available in bottled or canned formats, their distribution and presence may vary by location, possibly limiting their availability compared to the globally recognized Guinness. This broader reach solidifies Guinness as the brand that best fits the question's criteria.
