Wine cellars are not just a place to store wines. They should be the ideal environment where wines comfortably age so that the vintage carries its characteristics, complexity, and quality and reach perfection the way the master of the vintage intended it to be.
Thus, when you plan to build a wine racks, you must consider first a lot of things such as:
Make sure that the ceiling must have a minimum of R-19 insulation all the way around. You must take much closer attention to the insulation on the top of the cellar. This is because during warm climates, this, the ceiling or roof, is where most of your energy is lost. Make sure also that the door is well-insulated as well as your interior ceiling and wall covering material must be rot and mildew-resistant.
To make sure you get to achieve the ideal temperature within the cellar, a wine cellar cooling system must be provided to properly keep the climate of the cellar controlled at a temperature of about 55-58 degrees and humidity of 50-70%.
These cooling systems come in various types and sizes but in three basic designs: self-contained, split refrigeration, and split air handling. The most basic among the 3 is the self-contained systems, which are intended to fit through a standard wall. This unit can produce air that is 30°F colder than the air in the room outside the cellar.
These are some of the things you should take into account while building your own wine cellar. Nowadays, the most well-known is the "air Lock" recessed ceiling can lights. Make sure to place these on dimmer switches to control brightness. However, it is advisable to place all lighting on a timer system. Leaving the lights on for long periods of time can induce excess heat as well as cause the cooling equipment to overwork itself.
