New laser technology detects counterfeit alcohol through sealed bottles

July 17, 2026 - 21:09

A team of researchers at Adelaide University is working on a laser-based system that could let authorities identify counterfeit alcohol and dangerous chemicals inside sealed bottles. The technology, still in development, aims to detect deadly bootleg spirits and expose wine fraud without ever uncorking the container.

The method uses a specific type of laser to scan through glass and analyze the liquid inside. By measuring how the light scatters and interacts with the contents, the system can identify the chemical signature of the alcohol. This means inspectors could quickly spot methanol, the toxic substance often found in fake spirits that can cause blindness or death. It could also help verify the authenticity of expensive wines by confirming their chemical makeup matches the label.

Current testing often requires opening a bottle, which ruins the product and takes time. The new approach would allow law enforcement and customs officials to screen large shipments in minutes. The researchers say the technology could also be adapted for other industries, such as detecting contaminants in chemicals or pharmaceuticals.

While the system is not yet ready for commercial use, the team is optimistic about its potential to save lives and protect consumers from fraud. Further trials are planned to refine the laser's accuracy across different bottle types and liquid colors.
