fruit flies cruising at wine rack

[Mdrew]

I recently made up this wine rack. It's purpose built for 1000mL flip top bottles, and I think I've made a grave mistake. Some of the bottles sliiiiiightly leak by their flip top rubber gasket. This smells awesome to fruit flies, and they've become a problem down there.
Ya know, I could feel for the bottles that are leaking, replace the gasket, wash them thoroughly and put 'em back. That would probably be the best solution there.
Generally we store bottles on their side to keep the cork wet, but for these, that doesn't matter. What if the entire rack held them at a 30deg upwards angle, so the top would stay dry? I may have to redo this thing.

Any advice would be great. thanks!

Only bottles with corks need to be on their sides. Screw capped bottles and the flip top bottles can be stored standing upright.

Thank you @Ohio Bob any racks you might recommend for upright storage?

I don’t use racks for flip tops (aka Grolsch-style). I use totes. Not a great system as the bottles are just tall enough that the lid won’t completely snap down.

Like Bob I keep synthetic cork and Grosch bottles upright (in cases). ,,, The food inspector checks to see if rubber gaskets are old / cracking. You need to check for chips and cracks.
