He has written a paper describing his analysis of beer glass shapes and posted it on the arXiv preprint server. Prior research and a lot of anecdotal evidence suggests that beer consumers prefer their beverage cold—generally as cold as possible. Many such beer drinkers also prefer to consume their beverages from a clear glass—doing so allows for enjoying the look of the beer as it is being consumed and makes for an easy and tasty consumption.
Unfortunately, the two desires represent a conundrum— drinking from a glass allows the beer to lose its chill very quickly. Because of that, beer glass makers have developed a variety of designs meant to retain as much chill as possible, for as long as possible. In this new effort, Pellegrini put such designs to the test by calculating the optimal glass design, based on physics principles, for keeping a beer cold in a drinking glass.
In his work, Pellegrini did not include external factors, such as the warmth of a hand holding the glass, or the t.
