I always have space for 8 bottles per shelf (in a zigzag pattern). I can't manage 10, at most for white wine with very slim bottles. There's a bit more space at the top because it's higher. Heavy, thick-walled bottles with a base, such as champagne, don't go in as well because they need more space in the width. I'm happy with the appliance (in use since the end of 2023). It's in my cellar, I wouldn't want it in the living area as it's louder than a fridge.
