Aluminum, malleable, lightweight, recyclable, and safer than glass, is widely used for beverage cans. Its resistance to corrosion depends in part on the quality of the protective internal coating. When this coating presents defects in application or uniformity, corrosion can develop, particularly in the presence of sugar.
This article explains the mechanisms involved and proposes a protocol to evaluate the quality of can coatings.
In quality control, production, or research, comparing analytical results is part of everyday practice.
But what happens when two professionals — each confident in the reliability of their work — observe a discrepancy between their measurements?
It’s a common situation, often leading to tension, misunderstanding… or rushed decisions.
Example: Two laboratories measure the alcohol content of the same spirit sample. One reports 40.1% vol, the other 39.8% vol.
Who’s right? Are the results truly incompatible — or simply different within the range of measurement uncertainty?
This article provides a practical framework to interpret such differences rigorously, understand the role of measurement uncertainty, and assess whether two results can be considered technically consistent.

After discussing the origin of volatile aromatic compounds in fermented raw materials, this second article focuses on the role and importance of distillation control in achieving the desired eau-de-vie quality.
The final part of this series explores the key physicochemical changes that eaux-de-vie undergo during barrel aging.
This three-part series will conclude with an analysis of the impact of climate change on the composition of barrel-aged eaux-de-vie and the measures that can be implemented to maintain quality control
