How A Simple Bulge Has Protected Beers For Over A Century
The presence of a bulge on certain drink glasses, particularly pint glasses like the Nonic, is not merely an aesthetic choice. Did you know it serves a practical purpose rooted in functionality?
This design element, exemplified by the Nonic pint patented in 1913, continues to be prevalent in the beverage industry due to its straightforward benefits, according to drinks whizz Mandy Naglich @drinkswithmandy.
The benefits of the bulge
Rim protection: A key advantage
One of the primary advantages of the strategically placed bulge on a glass is the protection it offers to the rim.
The rim is inherently the most vulnerable part of the glass, susceptible to chipping or breaking upon impact. In environments where accidental knocks are possible, such as busy bars and pubs, this risk is amplified. The bulge, typically located approximately two-thirds of the way up the glass, acts as a buffer.
Should the glass be tipped over, this reinforced section is likely to make initial contact with the surface. By absorbing the impact, the bulge significantly reduces the stress on the delicate rim, thereby minimising the potential for damage and spillage.
The legacy of the Nonic pint
The enduring popularity of the Nonic pint, with its characteristic bulge, underscores the effectiveness of this design principle.
Patented over a century ago, its continued use worldwide is a testament to its practical utility in mitigating glass breakage.

This longevity highlights how well-considered design, even in seemingly simple objects, can provide lasting benefits.
Enhanced grip and stability
Beyond impact protection, the bulge also contributes to a more secure grip. The subtle outward curve provides a natural indentation for the hand, offering a better purchase on the glass.
This can be particularly advantageous when condensation forms on the exterior, which can otherwise make the glass slippery. The improved grip reduces the likelihood of accidental drops, further safeguarding the beverage and the glass itself.
