Stick-on thermometers, also known as LCD thermometers, are a convenient and easy way to measure temperature. They consist of a thin strip with a liquid crystal display that changes color based on the temperature. These thermometers are commonly used in various settings, including homebrewing and winemaking.
In my experience as a sommelier and brewer, stick-on thermometers have proven to be quite reliable and accurate. They provide a quick and straightforward way to monitor the temperature of a liquid without the need for additional equipment or complicated setups. This is particularly useful when fermenting or aging beverages, as temperature control is crucial for achieving desired flavors and characteristics.
One of the main advantages of stick-on thermometers is their simplicity. They are incredibly easy to use and require no calibration or setup. Simply peel off the backing and stick them onto a clean and dry surface, such as the side of a fermentation vessel or the outside of a wine barrel. The temperature reading is then easily visible on the display, allowing for quick monitoring and adjustments if necessary.
I have found stick-on thermometers to be quite accurate within a reasonable range. However, it is important to note that they may not provide the same level of precision as more advanced temperature measuring devices. For most homebrewers and winemakers, the accuracy provided by stick-on thermometers is more than sufficient for their needs.
Additionally, stick-on thermometers are versatile and can be used in a variety of situations. They can be applied to both curved and flat surfaces, making them suitable for various containers and vessels. Whether you are fermenting beer in a carboy, aging wine in a barrel, or even monitoring the temperature of your aquarium, stick-on thermometers can be a practical and reliable tool.
It is worth mentioning that stick-on thermometers are best suited for ambient temperature monitoring rather than precise liquid temperature measurements. While they can give you a general idea of the temperature, they might not be as accurate when it comes to measuring the exact temperature of the liquid itself. For more precise measurements, a dedicated thermometer specifically designed for liquid immersion would be more appropriate.
Stick-on thermometers, or LCD thermometers, are a practical and reliable tool for monitoring temperature in various settings. They offer simplicity, versatility, and reasonable accuracy, making them a popular choice among homebrewers, winemakers, and hobbyists. While they may not provide the same level of precision as more advanced temperature measuring devices, stick-on thermometers are a convenient option for quick and easy temperature monitoring.
