Wine tourism is becoming an increasingly important tourism niche with various regions competing for tourism dollars. It is often assumed that differentiation in the sector is region based. This research investigates the positioning narratives from websites of a sample of top wine tour service firms across the US and Australia. Analysis is undertaken using an innovative methodology that combines computer-based lexical analysis followed by hierarchical clustering on principal components. The research seeks to determine the extent to which identified clusters are region based and whether the positioning narratives on websites can provides useful clusters across regions. Results are reported, implications are discussed, limitations are noted and possible areas for further research are indicated.
