Wine is the most difficult single food or beverage to store.
Unlike your poultry, beef, or even dairy and soda, wine is a living grape. Its taste is directly impacted by how it’s stored.
Store it badly with too much light, humidity or higher temperatures, you will have “corked” or spoiled wine.
In this article, you will learn the problems of storing wine and how Sub-Zero and other manufacturers attempted to address these issues.
Hint: Only one company is successful, while most are not.
I was once fortunate enough to travel to the Hungarian wine country. This particular family vineyard produced premium Tokkai wine.
Their storage "system" was local caves.
Interestingly enough, a cave emulates the exact conditions of proper wine storage.
A cave has:
So you want your wine storage system to emulate these conditions - which doesn’t usually happen.
The early wine craze of wine in the 1990s caused many manufacturers to market wine storage products of all types.
Instead of designing a system geared to solving the problems of storing wine: Temperature, humidity, vibration, and light, most companies added pull out shelves to existing under cabinet refrigerators.
Many still had a light bulb on the top of the cabinet. So your wine was directly below a 75 watt light bulb. That’s kind of funny when you think about it (unless it’s your bottle).
All of them had a compressor vibrating when turned on. The shelves didn’t glide.
Almost all had one temperature control. The “two-zone” wine cooler merely reflected the temperature disparity between the top and bottom.
Most are still like that today. By the way, if you are not storing wine for long periods, its not as big a problem.
Sub-Zero did not turn an existing undercounter refrigerator into a wine cooler. It was designed independently 20 years ago to answer the problems surrounding wine storage.
Sub-Zero was the first to use a Low-e glass door to refract harmful UV light. Others have followed. Their lighting inside the cabinet is an indirect LED.
LED light emits way less heat with far less wattage than incandescent or halogen lighting employed by other companies.
The compressor of the Sub-Zero is mounted to rubber grommets, so there is little vibration when the compressor is turned on.
You have rollered shelving, so your wine glides out, unlike steel shelves welded to the sides of an existing refrigerator.
Sub-Zero employs two evaporators and is a true two-zone unit. You can set either zone from 39-65 degrees to store reds or whites.
You can also precisely set the temperature in 1-degree increments, unlike any other wine cooler.
The outside is sealed so air cannot infiltrate. The middle is also gasketed, so there is no temperature cross over between the two zones
You can tie in your wine cooler to home security as well. Attach the cable to the unit for that extra protection when there is an issue.
You have several finish options from panels to stainless steel.
You can choose from many sizes. The most popular is the 24-inch models holding 46 bottles in freestanding, built-in, or undercounter.
You can buy Sub-Zero wine columns in 18, 24, and 30 inches to store more bottles.
This unit will allow you wine with space for food or other beverages.
You have several less expensive competitors like ours, Uline, Marvel, and a host of other manufacturers for undercounter refrigerators.
Ours is much less expensive at $1,799 with a 5-year warranty compared to $3,500 for a Sub-Zero.
However, it does not offer the same features as Sub-Zero for protecting wine long term.
Perhaps True is the only competitor to Sub-Zero for long term storage of wine and wine preservation.
They are 2 zone units as well with vibration control and a low E door.
The units are even more expensive than Sub-Zero. They are somewhat new, so it is a bit unproven. Then again, True supplies half the supermarkets in the US, so they should know a bit about refrigeration
First, you should know wine is a living grape. How you store wine will have a direct impact on the taste.
You can consider other options if you drink just a few bottles or don’t store for a long time.
However, with better wine and longer storage, Sub-Zero will be your best choice in a field of retooled refrigerators masquerading as wine storage.
