Highball

A highball is a mixed alcoholic drink composed of an alcoholic base spirit and a larger proportion of a non-alcoholic mixer, often a carbonated beverage. Examples include the Seven and Seven, Scotch and soda, gin and tonic, screwdriver , fernet con coca, Tom Collins, and rum and Coke (a.k.a. Cuba libre with the addition of lime juice). A highball is typically served over ice in a large straight-sided highball glass or Collins glass. Highballs are popular in Japan, where the term haibōru (ハイボール) is synonymous with a whisky and soda (rather than an umbrella term for assorted mixers). Shōchū is used to make chūhai (チューハイ); various mixers can be specified by suffixing with -hai (〜ハイ), as in oolong highball (ウーロンハイ, ūron-hai). The name may have come from early railroad signals with raised globes meaning "clear track ahead", i.e., "you're good to go".
