The aim of this study is to extend an existing method to untangle the effect of taste (intrinsic) versus label information (extrinsic) on repurchase in a new-to-wine market. Results from a repeated discrete choice experiment (DCE) conducted before and after tasting a set of wines in China are compared with a control group that only performed the repeated DCE, but not the informed tasting. Fundamental differences were observed in choice response for the control group between the two sets, indicating a low stability of preferences and low test-retest reliability. There was a narrow range of responses for both the control and test groups, with an unusually high number of random choices recorded. The effect of extrinsic and intrinsic product attributes could not be determined. The method of combining discrete choice and tasting should be reassessed first in an established market. Other recommendations for conducting similar research in developing markets are discussed.
