Impact of bottle size on in-home consumption of wine: a randomized controlled cross-over trial.

ABSTRACT:

Aim

To assess the impact of purchasing wine in 50 cl bottles compared with 75 cl bottles on the amount of wine consumed at home.

Design

Cross-over randomized controlled trial with a 'usual behaviour' period of a maximum of 3 weeks between conditions.

Setting

Households in the United Kingdom.

Participants

One hundred and eighty-six households that consumed between two and eight 75 cl bottles of wine each week.

Intervention

Households were randomized to the order in which they purchased wine in two bottle sizes. During two 14-day intervention periods, households purchased a pre-set volume of wine-based on their baseline self-reported weekly consumption-in either 75 cl bottles or 50 cl bottles. On days 7 and 14 of each study period, participating households
