There are some limitations of the study that bear mention. Firstly, knowledge of brand loyalty is not based on actual buying behaviour identified via panel but reflects the declared loyalty of each respondent (see table 7). There was not applied control mechanism whether perceived willingness to beer brand switch fully answers real behaviour in the purchasing situations. Secondly, impact of the advertising on brand loyalty was studied generally although the role of social media as one of the communication tools for building strong brand is probably more stressed by Generation Y. Finally, consumer behaviour on the beer market including loyalty has not been searched across particular brands. There are numerous studies that are interested in that issue. Ehrenberg et al. (1990) holds that large brands receive more loyalty, while small brands receive less (double jeopardy effect). Bannelis et al (2013) adds that consumer loyalty is related to purchase incidence – heavy buyers of a category buy more brands, consequently are less loyal to any particular brand. The analysis of role for particular beer brands gives a potential for future research.
