Grapevine is a three-level course in British English running from complete beginner level to pre-intermediate level. Each level consists of 40 units, each of which takes a double-page spread. It is an extremely comprehensive series, which includes an integrated (but optional) video element, as well as a built-in extensive reading component, a listening development syllabus, tests and a Workbook which goes far beyond the basic exercises associated with Workbooks.
