The phrase represents a specific category of pizza commonly found in establishments that brew and serve their own beer. This pizza style is characterized by a generous application of mozzarella cheese. For example, a customer might order this type of pizza as an accompaniment to a particular craft beer offered at the brewing establishment.
The appeal of this pizza likely stems from its simplicity and the complementary relationship between the rich, cheesy flavor and the diverse profiles of craft beers. Historically, pizzerias and breweries have often co-existed, leading to the development of menu items that pair well with various beer styles. The combination offers a familiar and comforting dining experience. The abundance of cheese provides a satisfying texture and flavor that balances the bitterness or complexity of certain beers.
