Which of the following practices promotes proper beer rotation?

The practice that best promotes proper beer rotation is selling based on best before dates. This is because best before dates provide a clear indicator of the optimal time frame for consuming a beer to ensure its freshness and quality. By prioritizing sales of beers that are approaching their best before dates, establishments can effectively manage their inventory, reducing the risk of products becoming stale or losing their desirable flavors.

In contrast, storing beers by popularity can lead to a backlog of less popular beers that may not sell quickly, resulting in those beers potentially exceeding their best before dates. Focusing on seasonal promotions may also not address the inventory of all types of beers, as it often highlights only specific items that fit the current season rather than ensuring timely sales of all beers. Keeping all beers at room temperature would compromise the quality of many styles that benefit from refrigeration, leading to a negative experience for consumers and ultimately impacting sales. Therefore, using best before dates is crucial for maintaining freshness and ensuring customers receive the highest quality product.
