Traditional information based health campaigns have been largely ineffectual at changing long term health behaviours. In recent years, public health researchers have been trying new approaches to change health behaviours such as changing the choice architecture of environments to nudge individuals towards healthier behaviours. The studies in this thesis set out to investigate how altering the shape and design of glassware can change consumption and other alcohol-related behaviours. First, the feasibility of manipulating glassware in naturalistic environments was investigated. I found it was possible to change the stock of glassware in pubs and it was possible to use monetary takings as a proxy for consumption. Second, there was strong evidence that shape of glassware influences the pouring accuracy of liquid volume. Pouring was more accurate at 11 data points in straight compared to curved glasses in an online task. Straight and inverted glasses resulted in more accurate pouring compared to tulip and curved glasses. Third, applying a midpoint marker to curved glassware appears to have no meaningful effect on consumption speed. However, applying two additional markers at 1/4 and 3/4 slowed consumption marginally. Last, the effect of a design feature on lager glasses known as a nucleation stamp was investigated. I found evidence that lagers in nucleated glasses were rated as more visually appealing and refreshing than lagers in non-nucleated glasses. However, there was no direct evidence that nucleation affected the consumption of lager either in terms of volume consumed or speed of consumption. Whether glassware can change consumption and other alcohol-related behaviours depends on what aspect of the glass is altered. It remains to be seen if population alcohol consumption can be reduced via glassware based interventions tested in this thesis.
