Giancarlo Cignozzi, who owns a vineyard in Tuscany, Italy, claims that playing classical music for his grapes has resulted in a higher sugar content and fewer insect-related infections.

A winemaker in Tuscany, Italy has implemented an unusual approach to cultivating his grapes. 
A recent CBS News report states that Giancarlo Cignozzi plays classical music in his fields because “...he found the vines closer to the music grew bigger and toward the source of the sound.”
The experiment began sometime after the former lawyer bought the crumbling Paradiso di Frassina property in 1999 and decided to integrate his passion for music into the project. 
It has since evolved into a system where certain areas of the vineyard are continuously exposed to Mozart’s works through dozens of speakers placed around the property. 
The experiment has had some noticeable benefits, with Cignozzi’s winemaker son saying, “The plants seem more robust. The grapes closer to the speaker have the higher sugar content, so we believe in this idea.” 
They have also noticed fewer instances of infections from insects. 
Experts suspect the music’s vibrations and frequencies are behind the positive results.
