Minimum unit price (MUP) policies establish a retail floor price below which alcohol may not be sold, and have been shown to reduce harmful alcohol use. We aimed to collect retail price data to estimate the proportion of alcohol products that would potentially be impacted by a MUP policy in Western Australia.
We purposively sampled the four largest off-premises alcohol retail chains, a further random sample of other off-premise alcohol outlets (n = 16) and on-premise inner-city outlets (n = 11). Using website data from May to June 2021, we estimated the proportion of products across four beverage categories priced ≤A$1.30, ≤A$1.50 and ≤A$1.75 per standard drink (10 g alcohol).
Of 27,797 off-premise products identified, 5.7% were available at ≤$1.30 per standard drink, 7.6% at ≤$1.50 and 10.4% at ≤$1.75. The proportion of products available at ≤$1.30 per standard drink varied by beverage category: 7.8% wine, 2.9% beer and cider, <0.1% spirits, 0.0% ready-to-drink spirits. Cask-packaged wines represented only 1.9% of off-premise wine products and 98.9% of this cask wine was priced ≤$1.30 per standard drink. No on-premise products were priced ≤$1.75 per standard drink.
A comprehensive survey of alcohol prices in Western Australia found only a small proportion of products would potentially be affected by a MUP of $1.30 to $1.75 per standard drink. A MUP policy has potential to target the small proportion of alcohol products available at very low prices (i.e., off-premise cask wine), with negligible impact on other off-premise beverage categories, and no impact on on-premises products.
最低单位价格（MUP）政策设定了一个零售底价，低于该价格酒精饮料不得销售，并且已证明该政策可减少有害饮酒行为。我们旨在收集零售价格数据，以估计西澳大利亚州可能受MUP政策影响的酒精产品比例。
我们有目的地对四家最大的店外酒精零售连锁店进行抽样，另外还对其他店外酒精销售点（n = 16）和市中心的店内销售点（n = 11）进行随机抽样。利用2021年5月至6月的网站数据，我们估计了四个饮料类别中每标准饮酒单位（10克酒精）价格≤1.30澳元、≤1.50澳元和≤1.75澳元的产品比例。
在识别出的27797种店外销售产品中，5.7%的产品每标准饮酒单位价格≤1.30澳元，7.6%的产品≤1.50澳元，10.4%的产品≤1.75澳元。每标准饮酒单位价格≤1.30澳元的产品比例因饮料类别而异：葡萄酒为7.8%，啤酒和苹果酒为2.9%，烈酒<0.1%，即饮型烈酒为0.0%。桶装葡萄酒仅占店外葡萄酒产品的1.9%，且该桶装葡萄酒的98.9%每标准饮酒单位价格≤1.30澳元。没有店内销售产品每标准饮酒单位价格≤1.75澳元。
对西澳大利亚州酒精价格的全面调查发现，每标准饮酒单位1.30至1.75澳元的MUP政策可能只会影响一小部分产品。MUP政策有可能针对一小部分价格极低的酒精产品（即店外桶装葡萄酒），对其他店外饮料类别的影响可忽略不计，且对店内产品没有影响。
