Mine have 30 x7 or 210 bottles without any issue at all. Sounds like your talking 25 x 13 or 325 bottles. The shelves should hold as you have less weight per shelf than what I have so that just leaves the 4 poles to be concerned about. I think it should handle it but I would try and attach the shelf to a wall somehow and make sure its on a level surface to begin width. If you have a small tilt to begin with and add 325 bottles of wine that little tilt could become a big one over time.
If I double stack these shelves do you think it would be too much weight? Double stacking would allow me to put one 5 gallon batch per shelf.View attachment 83352
