Thanks Jules,
I thought about that very thing when deciding on the command strips. Each pair is rated for 8lbs sheer force and with 2 pair on each of 4 side brackets for each 5 bottles there are 8 pairs of command strips holding the load so 48lb of load capacity for 15 lbs of wine 
it may have been over kill but better safe than commit alcohol abuse by breaking wine bottles!
I spent more on the command strips than any other part…
