Best Wine Cellar Thermometers and Hygrometers
So, you got there. You built your dream wine cellar. You are surrounded by different bottles of wine, each more different and more interesting. You are thinking of expanding your collection, which assortment of wine works best with each type of food, but most importantly, you are thinking on how to preserve your wine stash in proper conditions for a more extended period of time (because, let’s face it, building such a collection does not come very cheap).
And scrolling through the information available online, you found out that a thermometer and a hygrometer are essential for your wine cellar. But you are not sure yet why they are so important. So, let us explain why humidity and temperature control are very important for your wine cellar, why you need a wine cellar thermometer hygrometer and the best wine cellar thermometer hygrometer.
Why is temperature critical for my wine cellar?
The best temperature that will preserve your wines in proper conditions is between 45- and 65-degrees Fahrenheit (4° to 18°C); if the temperature goes higher than that, your wine will age too fast, and you will lose the aromas. If you would like to store wines for a longer period of time, cooler temperatures are desired. Usually, wine wines are consumed faster than red wines; nevertheless, they benefit from the colder storage.
On the same note, make sure it is not freezing temperature either because the wines will not last long. The cold temperature will dry the corks over time, thus letting air in and destroying the wine. Ideally, the temperature should be kept at around 55 degrees Fahrenheit. Also, a refrigerated wine will suffer the process of slow aging, meaning it will not mature or gain anything from the aging process.
If you store the wines at room temperature (70°F/21°C or higher) or in a location where the temperature continually fluctuates (like the attic) various reactions will be accelerated in a bottle, but at different rates, resulting in a lack of balance in the aging process.
Why do I need to control the humidity level in my wine cellar?
Humidity is another essential aspect that you need to take into consideration when setting up your wine cellar. As stated above, a dry climate will also lead to cork shrinking, initiating the oxidation process because the corks will lose their sealing power and turning the wine into vinegar.
However, a too humid atmosphere will cause mold to develop, which will damage the labels and deface the bottles. The presence of mold and mildew will impact the flavor through the cork because the wine will absorb the environment’s aroma.
Ideally, the humidity should be kept between 50 and 70% for the best results.
How do I serve and store the wine?
Serving each wine at the right temperature will enhance the tasting experience and perfectly accompany the food served. To get the most out of your wines, serving each wine at the right temperature is essential. If you serve the wine too cold, it will lose all its complexities, but if you serve it too hot, you will likely feel the alcohol taste first, before any other flavor.
After serving the wine, the way you store it is even more critical. With the right temperature, preserving and developing the wine will become very easy.
What does a wine cellar thermometer do?
Now that you understood what improper temperatures can do to your wine collection, you realize that temperature management is essential. The easiest way to measure the temperature, know what the trend is and what changes you need to make in your space is getting a wine cellar thermometer.
What does a wine cellar hygrometer do?
Like the temperature part, you will need to pay very close attention to the humidity level. You can do that with a hygrometer, or humidity gauge, which is essentially a device that measures relative humidity/water vapor in an enclosed space.
Since the amount of moisture air varies based on the temperature, most hygrometers nowadays will display the humidity level and the temperature. The best way to measure the humidity and temperature in a particular location is by using a digital wine cellar thermometer hygrometer. In the following list, you will find several models that can accommodate any need, regardless of space’s dimension, the purpose of location or price, so you can be sure you will find the best wine cellar thermometer hygrometer for you.
Featuring an easy-to-read display that shows real-time temperatures and humidity levels and three-level indicators: dry/comfort/wet, this little gadget is straightforward to use. It has a built-in Swiss-made thermometer hygrometer sensor that provides precise monitoring, the temperature being accurate to ±0.5°F, while humidity is ±3%RH. Equipped with Bluetooth technology that allows you to remotely monitor the temperature/humidity on the Govee Home app, it has a range of 80m/260ft/3149 inch (with no obstacles).
Moreover, the intelligent app will send you an alert each time there is a modification of the preset temperature/humidity level and allows you to adjust the situation in real-time. With Free Data Storage, you can check the statistics and graphs for humidity and temperature for the past 20 days and export the latest 2-month data in CSV format anytime you need. It has a built-in stand and a hanging hole, so you will be able to place it anywhere in your wine cellar for closer and more careful monitoring.
Nevertheless, you need to consider that being a Bluetooth connected device, the range will only go so far, sometimes not far enough as you need it; for this reason, many people prefer the WiFi feature. You also need to pay attention to the location where you set your device because the screen will be dim and not visible enough from all angles or distances.
• Swiss made thermometer hygrometer for precise monitoring;
• Bluetooth technology;
• Alerts for humidity/temperature change.
• Bluetooth range possibly not large enough for everyone;
• Less visible screen from certain positions.
With a new type of technology, this digital thermometer/hygrometer is designed to combine the functions of measuring temperature and humidity, the wet-bulb temperature, and dew point temperature (it measures how much water vapor is actually in the air). The dual display of temperature and humidity has a range of 0% – 100%RH for humidity and a temperature range of -20℃(-4℉) – 60℃(140℉). The Dew point Temperature ranges from -50℃(-58℉) – 60℃(140℉) and the Wet Bulb Temperature from -20℃(-4℉) – 60℃(140℉).
The Protmex Thermometer Hygrometer features an LCD display, with backlight and high accuracy sensor, and it will auto power off after 15 seconds. With various functions such as data retention, data storage, unit conversion, and maximum & minimum functions, this gadget can be used successfully not only in a wine cellar but also in meteorology, medical field or engineering.
While the humidity (and temperature) changes are registered almost immediately within an environment change, the real values need a little time to stabilize before being fully accurately displayed.
• Wet-bulb temperature/dew point temperature monitoring;
• Data retention of up to 100 loggings.
• Needs time to stabilize before the accurate values are displayed correctly.
The ThermoPro TP50 Thermometer Hygrometer is equipped with highly sensitive sensors to accurately measure the temperature and humidity. Keeping any wine cellar within the preset values needs to maintain the quality of your product. The temperature ranges between -58°F ~ 158°F(-50°C ~ 70°C), with an accuracy of ±1°F, while humidity ranges between 10% ~ 99%, with an accuracy of 30%~80%: ±2%, out of range: ±3%.
Data measurements are updated every 10 seconds, and the face icon comfort indicator level will let you know if you need to humidify or dehumidify your space. Easily attachable to any wine rack due to the magnet on the back, you can tuck it away in any corner of your wine cellar because the screen is easy to ready, due to its high contrast.
As the device displays Humidity before Temperature, make sure you do not reverse and misunderstand the readings, especially when the measurements are similar. Also, after further testing from other customers, the conclusion is that the humidity level is not always accurately displayed (if you place two units side by side, you will get a slight difference), however, it is a close-range; if you need to know the exact levels, this might not be the unit for you.
• Fast update of temperature/humidity;
• Easily attachable/suitable for various places.
• The humidity level is not measured accurately enough;
• Humidity is displayed before temperature; there is a risk of mixing the two readings.
This pocket-size thermometer hygrometer that features an air comfort level indicator measures indoor humidity and temperature just timely for you to adjust them in any space you want to place it. With multi mounting design options, you can either set it on its stand, mount it on the wall or simply attach it to any metal surface due to its incorporated magnet, making it easy for you to find its own space. Equipped with 24 vents, the temperature range is around ±2.7℉ ( ±1.5℃), whereas the Humidity sensor accuracy range is around ±5%.
With a small, compact size, it updates every ten seconds, so you are ensured that you have the correct values in real-time. Habor has an excellent customer service that will reach out to you in case of any possible problem.
However, since its dimensions are so small, it will be quite hard to read from certain distances or angles; so if you know that your cellar is quite big and you do not want to walk straight to it to read the levels of humidity and the temperature, this might not be the option for you.
• Small, easy to place in any corner;
• Updates the readings every 10 seconds.
• Too small to be easily visible.
With a calibration feature meant to improve the data readings, you can set up your product in a step by step guided process for improved accuracy of temperature and humidity sensors. The humidity level ranges between 1% – 99% RH indoors, and the colorful display bar will indicate whether humidity levels are ok, too high, or too low.
Good with battery life and visible even in a dark cellar, it can be easily mounted on anything metal grace to its magnetic components or placed on a wall or tabletop, due to its mounting capabilities. Data measures update every 10 seconds, so you can be aware of your surroundings’ humidity and temperature. It will also show you the minimum and maximum for the past 24h and the trend for each of them.
The aspect that you need to take into consideration is that if you want to manually calibrate the AcuRite monitor, you will need an extra device (that it’s appropriately calibrated) so you have what to compare it with. In case of this one lacking, you could do the salt test, that you can easily find online. Also, the humidity will be displayed on top of the temperature, which can be counterintuitive for some people.
• Small and compact;
• Bright display, easily visible;
• Updates every 10 seconds;
• Can be manually calibrated;
• Consistent in readings when placed close to similar products.
• Need an extra device to compare it to when manually calibrating.
Compatible with Android, iOS (requires Bluetooth 4.0) and even SensorPush G1 WiFi Gateway (needs to be purchased separately) for remote access via the Internet, Sensor Push is the new step in monitoring the temperature and humidity level in your wine cellar. The humidity range is between 0-100% (accuracy: (@ 25°C / 77°F, from 20% – 80% RH ): ±3% typical ±4.5% maximum / @ 25°C / 77°F, from 0% – 100% RH ): ±4.5% typical ±7.5% maximum) and the temperature range is between -40°C – 60°C (-40°F – 140°F) (accuracy: 0°C – 60°C / 32°F – 140°F): ±0.3°C / ±0.5°F typical 0.5°C / ±0.9°F maximum).
The wireless range will go up to 100 m lines of sight if there are no obstacles in the way, and the sensors can be read virtually anywhere in the location or immediately outside it, meaning that you can take prompt actions in adjusting it when needed. Easy to setup and read, with batteries lasting more than one year, you can see the downloaded data in excel sheets or on your phone, divided over various periods (daily, weekly, monthly, yearly) and with specific graphs added to it.
While the sensors work flawlessly, you need to consider that the WiFi feature is still a new one that needs constant improvements, so this can be a disadvantage, mainly because you are charged extra for this extra function. Also, it has been reported that the device tends to crash after a few months, and it does not send timely alerts on your phone, so while the advantages seem very attractive, the downsides seem to equal them.
• Easy to setup;
• Long battery life;
• Detailed data are available to download.
• WiFi feature needs to be purchased separately;
• App and alerts tend to crash;
• Relatively short life spawn.
Like SensorPush, the Inkbird is a new generation thermometer hygrometer with the capacity to pair with Android and iOS phones to display humidity and temperature measurements. If you also purchase (separately) the Inkbird M1 WiFi Gateway, you will be able to receive the alerts via the Internet. The Bluetooth connection range is up to 30 meters, the app supports various languages, and you can select to display the temperature in °C /°F mode, depending on your preferences.
The temperature range is between -40°C~60°C / -40°F~140°F (Inner sensor), -40~212°F/-40~100°C (External Probe), while the Humidity Range is 0~99%RH. With a user-friendly app, you are able to download data and graphs, ideal if you need to keep track for a more extended period of time. You can set up alerts for temperature and humidity changes or just one of the two if you wish to know about only one of the changes.
As was the case for SensorPush, the app for Inkbird needs constant updates (sometimes, not so successfully made), so it might often crash. Moreover, you will indeed receive the alerts when temperature or humidity changes, but that will only happen if you open the app on your phone (so you have to remember to do this) and not when it’s in standby, making this feature a little pointless.
• User-friendly app;
• Option for Internet reading checking;
• The app tends to crash;
• Setup alerts only work when you open the app.

• Short life spawn.
Perhaps the smallest digital thermometer hygrometer from this list, Veanic comes in a pack of 4 pieces; the functions are very basic, only measuring temperature and humidity, but if you only need a gadget that will do this, this is the pack for you. Due to its size and the multiple units you receive, you can place them in various corners of your wine cellar, so you will know the temperature and humidity from the whole space. The humidity range is 10%-99%, with an accuracy of +/-5% and the temperature range is -58℉-158℉ with an accuracy of ±2℉ (under normal temperature).
Each unit has a vent for the sensor in the back, so you need to remember to leave some space behind. Easy to read and super simple to use, these compact units are accurate and very consistent with each other. If the price point is one crucial aspect for you, then you should definitely look into this set, especially because the customer service is also very prompt and helpful.
Of course that, being so small and simple, they do have their limitations. Therefore, you will not get a backlit screen, and you can’t change between the F or C scale. Also, you cannot calibrate these units, so if you are looking for specific values (not approximate ones), this is an aspect that might bother you.
• Very small, pack of four pieces;
• Consistent readings;
• Affordable price;
• Good customer service;
• Shows approximate readings (maybe not suitable for very professional use);
• No backlit screen;
• Cannot change between Fahrenheit/Celsius scale.
The 4-inch super large display of the Herphia hygrometer thermometer features touchscreen and backlight, which will make it easier to read from any angle and even in dim light. The temperature display unit is °C and °F switchable with a humidity range of 10% ~ 99%. Resolution:1% and a temperature resolution of 0.1 °C/°F. It is powered up by 2 AAA 1.5V batteries, the refresh rate is 10 seconds, and it will show the comfort level: low (dry), comfort or high (wet).
However, this is just an essential gadget that you use to measure temperature and humidity, so it is very suited for domestic use. Still, if you are looking for a professional tool, you might need to look further. Best fitted for measuring the levels in a small space, if you are not looking for exact values.
• Easy to use and read;
• Large screen with backlight.
• Mounting stands not very solid;
• LCD screen failure after some time.
After you have gone through our list of suggestions, let’s have a sum-up of all the information provided in this article, that you absolutely need to remember:
1. The best storage temperature for a wine cellar is between 45° F and 65° F, 55°F being cited as close to perfect.
2. The best humidity ranges between 50% to 70%, with 60% being ideal.
3. The best place to set your hygrometer is away from any moisture produced by the kitchen.
4. For a hygrometer to display the real value of humidity, you must wait a few minutes after placing the device in the desired location.
5. Digital hygrometers are more accurate because they also measure temperature and other environmental factors when displaying the humidity.
6. While digital hygrometers are more accurate than the analog one, they are factory calibrated when you receive them; however, some of them have the option of calibrating them manually if desired.
7. Some thermometer hygrometers nowadays can be connected to your phone by Bluetooth (or even WiFi), and you can receive alerts of any temperature/humidity change.
8. In case you need to calibrate your device, you will need a second one, that is very accurate in readings, to compare it to.
Hopefully, you found all the necessary information needed for you to set up or adequately maintain your wine cellar and wine collection so you can enjoy it over the years. The only thing left to advise you is to drink responsibly and enjoy every drop. Bottoms up!
