Linea Rouge is a red wine thermometer that uses the alcohol to indicate heat. This red wine thermometer was inspired by the [Grand Duke of Tuscany](https://www.trendhunter.com/trends/ramen-library), Ferdinando II de’ Medici who invented the modern thermometer in 1654. A capillary glass tub is filled with red wine which tells the temperature according to a wall-mounted numerological chart. ## Trend Insights (Trend Hunter) - Score: 2.4/10 - Popularity: 24% | Activity: 41% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Millennial - Top markets: North America, Europe ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Lifestyle](https://www.trendhunter.com/lifestyle) > [Drinking](https://www.trendhunter.com/drinking) ## Key Themes ### What's Driving This Trend - **Mercury-free Thermometers:** There is an opportunity for companies to create more sustainable temperature-taking devices by replacing mercury with non-toxic materials. - **Alcohol-based Indicators:** An innovative opportunity exists for companies to use alcohol as an alternative to mercury in various measurement devices. - **Historically-inspired Technology:** There is potential for companies to create new products that combine modern technology with historical design, such as the red wine thermometer inspired by the Grand Duke of Tuscany. ### Who This Affects Most - **Medical Devices:** There is a disruptive innovation opportunity for the medical industry to create sustainable and non-toxic thermometers to be used in healthcare settings. - **Lab Equipment:** There is a potential for companies that manufacture laboratory equipment to create alcohol-based indicators for various measurements during experiments. - **Home Improvement:** There is a market opportunity for companies in the home improvement industry to create historically-inspired and unique temperature-taking devices for consumers. ## Related on Trend Hunter - [Rosé-Dispensing Billboards](https://www.trendhunter.com/trends/dispensing-billboard.md) - [Portable Wine Coolers](https://www.trendhunter.com/trends/portable-wine-cooler.md) - [Magnetic Power-Free Food Thermometers](https://www.trendhunter.com/trends/food-temperature-detector.md) - [Sizable Wine Refrigerators](https://www.trendhunter.com/trends/equator-advanced-appliances.md) - [Relaxing Red Wine Tinctures](https://www.trendhunter.com/trends/red-wine-tincture.md) - [Metallic Wine-Aging Bar Tools](https://www.trendhunter.com/trends/peugeot-clef-du-vin-wine-tool.md) - [Customizable Wine Cabinets](https://www.trendhunter.com/trends/elegant-wine-cabinet.md) - [Libation-Cooling Glasses](https://www.trendhunter.com/trends/diamas.md) - [Sleek Smart Wine Cabinets](https://www.trendhunter.com/trends/wine-climate-cabinet.md)
