Protecting a Collection While the Unit Is Down

A wine cooler that stops holding its zones leaves you with two jobs: getting it repaired, and looking after what is inside it until then. On Mercer Island the second job can last longer than it would on the mainland, because a part that has to be ordered means a second trip over I-90 before the unit is whole again.

This note is about the bottles. What happens on our side during that gap is in the note on waiting on a part.

The first hour: measure before you move anything

The urge is to start carrying bottles out. Hold off until you know how fast the cabinet is warming, and in the meantime avoid three habits. Opening the door to feel the bottles lets in air the unit then has to cool. Switching the unit off and on to see whether it recovers erases the pattern we diagnose from. And unloading a whole cabinet onto a kitchen counter swaps a slow problem for a fast one.

Measure instead. A probe in a glass of water, one per zone, tells you what the wine is actually at. A zone creeping up by the hour, a zone stuck a few degrees high and a zone already falling back toward its set point call for three different decisions, and only the readings tell them apart.

If the bottles have to come out

Sub-Zero’s own short list of what harms wine, heat, humidity, vibration and light, doubles as a guide to where bottles should wait. Choose the room that stays most even through the day: dark, clear of the sun, the range and the furnace, and with no appliance running against the wall. An even room is better than one that is cool at night and warm by afternoon, because wine stored through frequent temperature swings tends to develop early.

Move the bottles you are keeping longest first, and lay them down the way they sat on the racks. Everyday bottles you will open soon can stay behind the closed door. Lift bottles off each rack by hand while the rack is still in its tracks: Sub-Zero’s guide for its undercounter wine racks says to unload every bottle before a rack is taken out.

Damp and smells while it stands

A cabinet that sits switched off with the door shut, or runs warm for days, can come back with a musty smell or damp labels. Wipe it out before reloading. If the damp keeps returning after the repair, the Lake Air note on damp labels and mold follows where that moisture comes from and how Sub-Zero says the interior should be cleaned.

Loading it back

Wait until the repaired unit has brought both zones back to their set points on the probe, not only on the display. Then return the moved bottles in two or three lots rather than all at once, so a freshly repaired unit is not asked to pull a whole collection down from room temperature in one go. The repair itself is booked as wine storage repair, and both zones are probed before we leave, so you know the cabinet is holding before the collection goes back in.

Before you call

1. Step 1

   Keep the door shut and the bottles racked

   Each opening lets in room air the unit is already struggling with. Until you know what the zones are doing, leave the load where it is and resist checking it every hour.

2. Step 2

   Stand a probe in each zone

   Sit a thermometer probe in a cup of water halfway up each zone; the water reads what the bottles are at, whatever the display claims. Check it at night and again at breakfast.

3. Step 3

   Log the readings with the time

   Three or four timed readings show whether a zone is creeping up, sitting still or recovering, and that trend decides more than any one number.

4. Step 4

   Pick the steadiest room in the house

   Somewhere dark, out of the sun, away from the range and the furnace, with nothing humming against the wall, in case some bottles have to come out.

Asked about this

Should we switch the wine unit off while the part is on order?

Not on a hunch. A unit still pulling its zones close to their set points usually serves the wine better running than a dark cabinet drifting to room temperature. Switching it off and on to test it also wipes out the pattern we read. Ask Mercer Island Sub-Zero Service on (206) 208-3377, and we will say which applies to your unit.

How long can the bottles stay in a unit that is running warm?

We will not give you a number, because the answer depends on how warm the zone is, what the wine is and how long you meant to keep it. What we can give you is the trend: probe readings taken morning and evening show whether the unit is holding, drifting or failing, and that is what decides whether the bottles move.
