What type of glass is typically used for serving a Boiler Maker?

A Boiler Maker is traditionally served using a rocks glass, which is a short and broad glass suitable for mixed drinks. The cocktail typically consists of a shot of beer and a shot glass containing a shot of whisky or bourbon. This glass is ideal because it allows for the easy combination of the shot into the beer, making it a popular choice for this type of drink.

Using a cordial glass would not be appropriate, as it is designed for serving small, sweet drinks and lacks the volume needed for a Boiler Maker. A cocktail glass, being designed for shaken or stirred drinks, would also not accommodate the drink effectively. Similarly, a champagne glass is specifically for sparkling wines and is not suitable for serving beers or shots in a timely manner required for a Boiler Maker. Therefore, the rocks glass is the most fitting choice for this classic drink.
