There is consistent proximity throughout the logotype. The negative space forming the "N" makes sense with the name because looking at the logotype engages the audience when locating the "N". I also think the logotype font works well bold.
here are different logos for different types of wine. These logos are all very different but all very smart and thought out. My favourite one is the one as i like the way the wine bottles fold over each other and i like how they are almost transparent.
