The only bartending methods are American bartending and English bartending. Fancy is a branch of American bartending, and Japanese is a branch of English bartending. To tell the difference, American bartending is free and casual, and the style and service of bartending are informal. English is more gentlemanly and easygoing. I like shirts, waistcoats and ties, which are a little serious and formal. If I were a playboy, I would focus on acting and really go for a few drinks.
If you want to learn English to mix wine, you are more orthodox, practical and skilled.
