The short answer
How do you look after a wine fridge?
Keep bottles a finger's width off the back wall so they cannot freeze, and check the real temperature with a glass of water inside. Clean the cabinet two or three times a year with warm water and mild, unscented soap, never with bleach or strong-smelling cleaners. Move it empty and upright, then let it stand before switching it back on: a few hours, or a full day if it travelled on its side. For magnums and Champagne, plan a space: rated capacity assumes slim Bordeaux bottles, so wide bottles need the base or a removed shelf.

Bottles freezing, or ice on the back wall
This was one of the most common problems I saw in service cabinets. It almost always has one of four causes, and the first is by far the most frequent.
- Back wall contact
In many wine fridges the back wall is the cooling plate. A bottle pushed against it can freeze while the rest of the cabinet is at the right temperature. Leave a finger's width of space behind every bottle.
- Setting too low
Check the real temperature with a thermometer in a glass of water. If it reads below 45°F on a storage setting, raise the setting a few degrees and check again the next day.
- A cold room
Most wine fridges can only cool. In a winter garage or an unheated basement colder than the setting, the inside falls with the room. Move it, or choose a model with a heating function.
- A blocked drain
Many fridges melt frost off the back wall and drain the water through a small hole at the bottom. If that hole is blocked, water pools and refreezes. Clear it with a pipe cleaner when you clean the fridge.
Watch for
A bottle that froze is usually still fineWine starts to freeze at around 20°F (−7°C). If the cork has not moved and nothing leaked, let the bottle thaw slowly in the fridge and drink it soon. Harmless crystals may appear: they are tartrates, not glass. If the cork has pushed out, air has reached the wine, so open it within a day or two.
Start with the back wall: moving the bottles forward fixes most freezing before anything else needs checking.
Cleaning a wine fridge, step by step
- Empty it first
Bottles are fine for a few hours in the coolest room you have, or in a cooler box for longer. Note which shelf each came from if you keep an order.
- Switch off and unplug
Leave the door open so any frost on the back wall can melt. Lay a towel at the bottom.
- Wash it gently
Unscented dish soap, or a spoon of baking soda in warm water. No bleach, ammonia or scented sprays: smells linger in a closed cabinet. Wipe the shelves, walls and door glass, then dry everything fully.
- Drain and door seal
Run a pipe cleaner through the drain hole. Wipe the door seal and close the door on a sheet of paper: if it slides out with no resistance, the seal is not closing.
- Dust the vents
Vacuum the grille at the front or back, wherever your model vents. Dust makes the compressor work harder and run louder.
- Cool it, then reload
Switch on and wait until it is back at temperature, usually a few hours, before the bottles go back in.
- Wipe a spill the same day. Wine dries sticky and feeds mould in a humid cabinet.
- Mould on labels means the humidity is high or the air is still. Wipe the labels and walls, and open the door for a few minutes once a week.
Two or three cleans a year, plus wiping spills when they happen, keeps a wine fridge fresh for its whole life.
Moving a wine fridge without damage
- Take every bottle out
However short the trip. A loaded fridge is heavy, the glass and shelves take the strain, and one jolt can break bottles inside a closed door.
- Tape shelves and door
Remove loose shelves or tape them in place, and tape the door shut with painter's tape that will not mark the finish.
- Keep it upright
A compressor fridge carries oil that can run into the cooling pipes if it is laid flat. Move it standing, on a dolly, with two people.
- Let it settle
Give it a few hours upright in its new spot, and a full day if it had to travel on its side. The maker's manual gives the exact wait for your model.
- Level it, leave space
Adjust the feet until it stands level, so the door closes and the compressor runs quietly. Leave the ventilation gap the manual asks for.
Empty, upright and patient: those three keep a move from becoming a repair.
Magnums, Champagne and bottles that do not fit
The bottle count on a wine fridge assumes slim Bordeaux bottles on every shelf. In service, the magnums and the wider Champagne and Burgundy bottles were always the ones that would not go in. A home fridge has the same problem, and it is easier to plan for before you buy than after.
| Bottle | Diameter | Length |
|---|---|---|
| Bordeaux 750ml | 3.0 in / 75 mm | 11.4–12.0 in / 290–305 mm |
| Burgundy 750ml | 3.1–3.4 in / 80–85 mm | 11.3–11.8 in / 286–300 mm |
| Champagne 750ml | 3.3–3.5 in / 85–90 mm | 12.5–13.0 in / 317–330 mm |
| Magnum 1.5L | 4.0 in / 102 mm | 13.5 in / 343 mm |
Common shapes; individual producers sit outside these ranges in both directions.
- Use the base. The bottom of most fridges takes bottles lying flat with no shelf above, which is where magnums go.
- Remove a shelf. Taking one shelf out makes a tall bay for Champagne and Burgundy, at the cost of a few Bordeaux spaces.
- Stand sparkling upright for a short time. For bottles you will open within a few weeks, standing does no harm.
- Before buying, measure your longest bottle against the inside depth, and look for shelves that slide out or can be removed.
Count your wide bottles before you choose a fridge, and expect to fit fewer of them than the number on the box.
Signs it needs a repair
- Not cooling: check the vents for dust, the door seal and the room temperature first. If all three are fine and it stays warm, call a technician.
- Running all the time: often a hot room or blocked vents; if neither, the seal or the cooling system needs a look.
- Ice building again soon after a clean: the drain or the door seal is the usual cause.
- New rattling or buzzing: check it is level and that no bottle or shelf is touching the back wall.
What this means for your fridge
Bottles off the back wall, a clean two or three times a year, and an empty, upright fridge whenever it moves.
Back to the Wine Fridge GuideCommon questions
- Why is my wine fridge freezing bottles?
- Usually because bottles are touching the back wall, which is the cooling surface in many wine fridges. Leave a finger's width of space, check the real temperature with a glass of water inside, and raise the setting if it reads too low.
- How do you clean a wine fridge?
- Empty it, unplug it and let any frost melt. Wash the inside with warm water and mild unscented soap or baking soda, dry it fully, clear the drain hole, then let it cool back down before reloading.
- Can you lay a wine fridge down to move it?
- Avoid it. Move it upright if you can. If it has to travel on its side, let it stand upright for a full day before switching it on, or the wait your manual gives.
- Will magnums fit in a wine fridge?
- Often not on the shelves. A magnum is about 4 inches across and 13.5 inches long. Most fridges take them on the base or in a bay made by removing a shelf.
- Why is my wine fridge not cooling?
- Check that the vents are free of dust and have space around them, that the door seal closes tightly, and that the room is not too hot for the model. Thermoelectric fridges in particular struggle in warm rooms.
