Which type of faucet is most commonly found on a beer engine?

A swan neck faucet is the type most commonly found on a beer engine. This design features a long, curved spout that helps create a smooth flow of beer by reducing turbulence as it pours into the glass. The silhouette of the swan neck also allows for better clearance when pouring, preventing beer from splashing and possibly wasting the product.

Moreover, this faucet is designed to facilitate the right pour, which is vital for achieving the proper head on the beer. The curvature of the swan neck contributes to both aesthetics and functionality, providing brewers and bartenders with greater control over the pouring process, which is particularly important for cask ales where preserving the natural carbonation is essential.

Understanding the design and function of a beer engine's faucet is crucial for serving traditional ales, as it affects not only the presentation but also the overall quality of the beer being served.
