I'm planning to make fairly simple racks like these: https://www.amazon.com/Stackable-Modular-Storage-Wobble-Free-Capacity/dp/B008XPLJFO?th=1 I'm wondering just how high I can go. I'm going to be framing up walls in my mud room to be my cellar and it'll have wall vented cooling. The total height of the room is about 10 feet. I probably won't stack wine that high, but 8 feet maybe, then a shelf at the top for some storage. I would be linking all the racks together (like a vertical strip once everything's assembled) then likely angle iron mounting that to the wall. I'm picking this design because it'll be super easy to make with 2x4s for the stackable layers and 1x4 for the bottle racks. Any thoughts on the limit of stacking?
