The kitchen rack is convenient. The hall closet is darker. The guest room feels cooler, except when the heating is on. You need a way to compare those places without assuming that the darkest corner is automatically suitable for years of storage.
Separate bottles for the next occasion from bottles for years ahead
Write down what you expect the space to do. Holding a few bottles for an upcoming dinner and keeping a case for several years are different requirements. Do not give every bottle a distant drinking date before establishing where it will live.
For long-term storage, the Wine & Spirit Education Trust recommends controlled, consistent temperatures of 50 to 59°F (10 to 15°C), away from bright light. It flags temperature changes in kitchens as a concern. These are storage conditions, not a serving-temperature rule. Source: WSET storage guidance.
Compare two or three real locations
Make a short list of spaces you can actually use. Inspect each for nearby heating, direct sun at different times of day and practical access. Then measure temperatures in the proposed bottle position rather than relying on how the room feels.
A min/max thermometer or temperature logger can help you collect observations. Record the dates and conditions alongside the readings. A range observed during a mild September week does not tell you what happens in July or when winter heating starts.
The worksheet below is a way to document your comparison. It is not a pass/fail test or a prediction of how any particular wine will age.

Keep observations separate from conclusions
Suppose a hall closet measures 61 to 66°F (16 to 19°C) during the week you check it. That is useful information, but it does not match the long-term range above. "Dark and convenient" is not enough to call it controlled storage.
Alternatively, you may have only one reading from a guest room. Mark the missing information rather than choosing the room on that evidence. The next step is to observe it under the conditions you have not checked, not to label it suitable for aging.
If none of the available spaces meets your long-term needs, compare a temperature-controlled cabinet or managed storage against keeping a smaller collection. That decision should follow the storage requirement and available space, not the advertised bottle count of a cabinet.
Check how the bottles will sit
WSET advises storing cork-closed wine on its side and says screwcap bottles may stand upright. A domestic refrigerator is not its recommended solution for prolonged storage of cork-closed bottles. See the same WSET guide for the storage principles.
Test your proposed arrangement with the bottle shapes you own. Leave a way to retrieve a bottle without emptying a whole shelf. Record the usable capacity you can work with, including larger bottles and cases, before allocating the entire collection.
Give the chosen spot a name and a review date
Once you choose a location, record which bottles go there and save the observations with the location name. Use a note such as "Hall closet, checked September 9; summer conditions unknown" instead of an unsupported claim that the wine is perfectly stored.
Repeat the check when the conditions you were missing arrive or the room changes. If bottles need to move, update their locations at the same time. The rack and row guide covers that inventory step; the drinking-window guide explains how to keep estimates separate from certainty.
If the place you choose is a cooling cabinet rather than a closet, decide in advance what happens when it fails. The equipment failure guide covers the order to move bottles in and what to write down.
