A Nonic glass is a traditional English-style pint glass that has a curved lip about close to the top of the glass. A Nonic typically holds an imperial pint or 20 oz. The flare at the top of the glass aids in the grip of the glass and can prevent the glass from slipping from your hand when condensation is present on the outside of the glass.
This glass is typically used to serve English ales and English lagers but can be used to most lagers and ales. These are great everyday beer glasses and classy upgrade to shaker type pint glass.
Nonic glasses are a universal beer glass that can be used to serve most types of ales and lagers. Having Nonic glasses behind your bar also lends to an English Pub motif.
