To keep the bottles quiet and safe, the wine racks have double slats in the front. This gives the required stability.
In addition, somewhat misshapen bottles (e.g., bottles with a “belly”) store more securely because the weight is against the back and cannot shift forward.
One reason that should not be neglected is the appearance. If all the bottoms of the bottles are stored forward, this will give a calmer and more uniform image.
As simple as it is logical, the label is immediately legible when pulled out and is not upside down.
However, we can assure all users that storage with the neck of the bottle facing forward is also possible.
