The Wine Bar

Polypins, which are essentially bag-in-box containers, are often used in cellars to serve beer. This method of serving beer is not only practical but also helps to maintain the freshness and quality of the beer. The beer is stored in the polypin in the cellar, where the temperature is typically cooler, thus ensuring the beer remains at an optimal temperature. This method of serving beer is particularly popular in pubs and breweries, as it allows for larger quantities of beer to be stored and served efficiently. The use of polypins in cellars for serving beer is a testament to the industry's commitment to preserving the quality and taste of their products.
