For the chūhai sold in bars and restaurants, the alcohol content can be quite low, allowing those with a low tolerance for alcohol to imbibe safely. Canned chūhai, however, can have alcohol levels as high as 9% (18 proof) and is often sold in convenience stores and vending machines. Chūhai is served in tall glasses or mugs as drinks for individuals, making it less social than other traditional Japanese bar drinks like sake, beer, or whisky, which can be shared by pouring portions from a large bottle. Fresh chūhai nama chūhai(生酎ハイ?) is also sometimes served, featuring fresh-squeezed juice; in some cases guests squeeze their own juice. Due to the high sugar content, the number of calories in each bottle can be quite high compared to other alcoholic beverages.
