Any thoughts on the optimal space/height between shelves for storing bourbon (or other whisk(e)y)? I've noticed that the tallest bottles/boxes generally seem to be about 14" in height. I'm working on a shelving project and I'm trying to decide how many shelves I want in a certain space -- which, of course, is in part dependent on the height in between the shelves. If I do 18" or 20" inches between the top couple/few shelves, then the lower shelves will need to have far less height in between (e.g, 12"/13") -- which means the taller bottles cannot fit on the lower shelves. If I try to make it so the taller bottles could go on any shelf, then I likely would have very little, if any, clearance between the top of the taller bottles/boxes and the start of the next shelf. Do you guys care about having plenty of clearance space above the top of the bottle/box or do you just care about the bottle/box fitting in the space period (or do you think I'm nuts and not care about any of this)?
Any other thoughts, concerns, tips, advice re: bourbon shelving in general?
I apologize in advance if (a) this line of questioning is too esoteric even for this board (I doubt it), and (b) if this post belongs elsewhere.
