You have two choices when searching for a wine cooler: compressor or thermoelectric? Compressor wine coolers are normally bigger and more powerful, but a thermoelectric wine cooler provides a few benefits compressor coolers can’t match.
How a Thermoelectric Wine Cooler Works
Thermoelectric wine coolers cool wine using the Peltier effect. It’s named after Jean Charles Athanase Peltier, the French physicist who discovered it. The effect is simple. When you run an electrical current through the junctions of a semiconductor plate made of dissimilar metals, one side transforms the electrical current into heat while on the other side transforms heat into electricity. This causes one side to get warm while the other side gets cold.
In a NewAir thermoelectric heater, the heat generated by the plate is immediately dumped outside by a heat sink, a large piece of metal with aluminum wings that protrudes out behind the unit and dissipates warmth into the surrounding air. The semiconductor plate it fixed with thermal paste, so the heat is transferred directly outside. The cold air generated by the Peltier effect remains trapped inside the unit, maintaining a cool, consistent temperature for your wine.
How They Benefit Your Wine
Because no motors or moving parts are required to create the Peltier effect, thermoelectric wine coolers use very little electricity and produce no vibrations at all. Vibrations are an important concern because they can upset the chemical balance in your wine and ruin the aging process. Even small amounts of vibration can be harmful if their effects are allowed to accumulate. Vibrations decreases the amount of tartaric acid in wine. Tartaric acid is the natural acid found in grapes and it’s what gives wine its taste, feel, and color. Vibration also decreases the level of succinic acid in wine. Succinic acid are the primary catalyst that forms esters, another important component of wine flavor.
On the other hand, vibrations increase the wine’s refractive index, which makes the wine sweeter, and increases the amount of propanol and isoamyl alcohol in the wine, which degrades the wine’s aroma. Instead of a rich, full flavor, it ends up smelling like potatoes, fuel, whiskey, or bananas.
Thermoelectric Wine Coolers vs. Compressor Wine Coolers
Compressor wine coolers operate like refrigerators. They use motors to compress refrigerants and then evaporate them to create cold air. Though this is a powerful cooling technique, it also produces a lot of vibrations. The compressor’s motor has to cycle regularly to keep producing cold air. NewAir thermoelectric wine coolers let you avoid those risks. They provide a solid and stable environment for your wine. It remains cool and protected until you’re ready to drink.
