Canned beer is a type of beer that is packaged in aluminum cans instead of bottles. This method of packaging helps to protect the beer from light and oxygen, which can affect its flavor and freshness. Cans are also lightweight and portable, making them a popular choice for outdoor activities and events. The process of canning beer involves filling the cans with the brewed beverage and sealing them to maintain freshness. Many breweries, including large companies and craft breweries, have adopted this method due to its convenience and environmental benefits, as aluminum cans are recyclable and often have a lower carbon footprint than glass bottles.
