The choice of format depends on the type of beer or cider you produce, your target market and the context in which the product will be sold or consumed.
The 330ml format is the classic single-serve size, ideal for retail, pub sales and events. It is the most immediate format for customers discovering a new product and works well for higher-strength beers or those with an intense character, where a smaller portion is enough.
The 500ml format is the European standard for craft beer. It suits a very wide range of beer styles, from lager to IPA, stout to wheat beer. It is the preferred format for sales in delis and specialist shops.
The 750ml format is the sharing size, associated with special beers, abbey ales, premium ciders or seasonal releases. It is a strong choice for producers who want to position their product as premium and stand out from supermarket offerings.
