Bubbles for bubbly - creating a wine cellar with curved edges is so cool on a metaphorical level. But I also really love this space in practice. While the walls' curve does limit the actual amount of wine storage space available, it lends a cool underground tunnel feel to the space and just looks really great.
I just imagine walking the Italian countryside and coming across some door in the side of a cliff. I walk through the door and into a fantastic wine cellar.
Here, the clean lines of the wine storage are a nice counterpoint to the rustic table and stone surroundings.
